Cryogenic Tank Manufacturers: Meet the Industry Leader Cryotanx

The invisible backbone of modern industry (medicine, energy, food production, and metalworking) is the ability to store critical gases in a liquid state at extremely low temperatures, such as -196°C. Liquid Nitrogen (LIN), Liquid Oxygen (LOX), Liquid Argon (LAR), and Liquefied Natural Gas (LNG) ensure the uninterrupted operation of these industries. However, storing these valuable liquids safely and efficiently is only possible with “cryogenic tanks,” which require a high level of engineering discipline.

When researching the market for “cryogenic tank manufacturers,” purchasers and engineers often encounter a complex market structure: distributors, importers, assemblers, and full-scope manufacturers. This distinction is of critical importance. A cryogenic tank is a decades-long, capital-intensive (CapEx), and high-risk investment. A vacuum failure or a weld crack can lead not only to a halt in production but also to catastrophic safety incidents.

Your search for a “manufacturer” is essentially a search for “risk avoidance.” This means purchasing not just a tank, but the engineering assurance, quality control processes, and long-term support behind that tank.

A true manufacturer is a company that manages the process from start to finish:

• Engineering: Performs complex pressure and stress calculations according to international codes like ASME and PED.

• Material Science: Selects the correct stainless steel alloys that will not embrittle at -196°C.

• Welding Engineering: Implements certified welding procedures that guarantee zero leakage.

• Vacuum Technology: Creates the deep and permanent vacuum that determines the lifespan of the tank.

• Testing and Quality Control: Inspects every single weld seam with Non-Destructive Testing (NDT).

Cryotanx is the exact embodiment of this definition. We are not just a supplier offering standard products; we are an engineering partner that designs according to your project’s specific requirements, brings these designs to life in our domestic production facilities, and supports you throughout the entire economic life of your tank. When you work with us, you buy not just a tank, but over 20 years of operational excellence and an unwavering promise of safety.

This comprehensive guide contains the answers to all the critical questions you need to ask when selecting a cryogenic tank manufacturer and transparently reveals Cryotanx’s expertise and competence in this field.

What is a Cryogenic Tank and What Should a Manufacturer Guarantee?

For engineers or procurement specialists new to the subject, a cryogenic tank works fundamentally on the principle of a giant “thermos.” However, this simple analogy hides the complex engineering lying within.

The Structure of a Cryogenic Tank

A cryogenic tank consists of two nested vessels (walls):

• Inner Vessel: Usually manufactured from austenitic stainless steel such as 304L or 316L. This vessel is in direct contact with the cryogenic liquid reaching down to -196°C and is designed to withstand high pressure.

• Outer Jacket: Usually made of carbon steel, providing structural integrity.

• Annular Space: The space between the two vessels. This space houses two critical components that determine the tank’s performance:

  • Insulation Material: Usually perlit (expanded volcanic glass) or Multi-Layer Insulation (MLI) is used.

  • High Vacuum: All air in the space is evacuated and brought to a very low pressure (deep vacuum) such as <50 microns.

Since air itself (especially Oxygen and Nitrogen) would freeze in this space, heat transfer (conduction and convection) is almost completely cut off. This vacuum insulation is the only thing protecting the -196°C liquid inside from the +30°C ambient temperature outside.

What Should a Manufacturer Guarantee?

When buying a cryogenic tank, the manufacturer’s guarantee should not just be “water tightness of the tank” (i.e., holding pressure). This is already a necessity. The truly critical guarantee is the tank’s “heat tightness.”

There are three fundamental guarantees a manufacturer must provide you clearly, measurably, and in writing:

1. Structural Integrity and Safety Guarantee: The manufacturer must guarantee that the tank is designed, manufactured, and tested according to internationally accepted standards such as ASME, PED, or AD 2000. This is the assurance that your tank will operate safely at the specified design pressure (e.g., 18 bar) and low temperatures without embrittlement or cracking.

2. Vacuum Life Guarantee: Poor welding quality, inadequate vacuuming processes, or poor-quality materials lead to the deterioration of the vacuum over time (sometimes within months). When the vacuum fails, the outer surface of the tank begins to “sweat” (ice up), and heat leakage increases rapidly. A good manufacturer should provide a guarantee on vacuum quality (usually 5 years).

3. Certified Boil-Off Rate (BOR) Guarantee: This is the most important yet least discussed technical metric indicating a manufacturer’s quality. The main enemy in cryogenic storage is “heat leak.” No matter how perfectly a tank is insulated, there will always be a minimum heat leak. This heat continuously boils a portion of the liquid, turning it into gas (Boil-Off Gas – BOG). This gas raises the tank pressure and is eventually vented to the atmosphere through the safety valve.

   • BOR (Boil-Off Rate) is the rate showing “what percentage of the liquid inside the tank will boil off and be vented to the atmosphere within 24 hours” (e.g., 0.15%/day).

Why is BOR So Important?

A tank bought from a low-quality manufacturer might have a BOR of 1%/day. A tank produced with Cryotanx’s superior engineering and vacuum technology might have a BOR of 0.15%/day.

• Low-Quality Tank: 1% loss per day in a 50,000-liter tank = 500 liters of lost gas.

• Cryotanx Tank: 0.15% loss per day in a 50,000-liter tank = 75 liters of lost gas.

The difference is 425 liters of expensive liquid gas that you vent into the atmosphere every day. Within a few years, the low-quality tank will make you pay the price difference many times over in lost gas costs.

As Cryotanx, we guarantee not only structural integrity but also an optimized, low BOR rate that will save you money every day.

Our Production Portfolio: Comprehensive Cryogenic Storage Solutions

Cryogenic storage needs are not homogeneous. The daily flexible need of a research lab and the massive, constant storage need of an LNG power plant cannot be met with the same engineering solution. The breadth of Cryotanx’s production portfolio shows that we are not just a “product manufacturer” but a “scalability partner” in our customers’ growth journeys.

Regardless of the scale of your need, Cryotanx’s engineering capability offers the most suitable solution for your operation with the advantages of domestic production.

Liquid Nitrogen (LIN), Oxygen (LOX), and Argon (LAR) Tanks

These are the backbone of uninterrupted, high-volume gas supply for industrial facilities, hospitals, welding workshops, and chemical plants. Cryotanx produces vertical or horizontal tanks in volumes ranging from 3,000 liters to 60,000 liters (or more for special projects) and in different pressure classes (e.g., 8, 18, 22 bar). These tanks feature optimized BOR rates to maximize the reliability and efficiency of your industrial gas supply.

LNG (Liquefied Natural Gas) Tanks

Key to energy transition and off-grid power plants, LNG is one of the most challenging areas of cryogenic storage. LNG stored at -162°C requires special safety protocols and often dual safety systems. Cryotanx designs and manufactures high-security LNG storage tanks compliant with international standards (e.g., EN 13645) to help industrial facilities lower energy costs, assist the marine sector in complying with emission rules like IMO 2020, or provide energy to locations without grid access (hotels, factories).

Microbulk Solutions

This is the smartest way for medium-sized enterprises (SMEs) to switch to cryogenic technology. The logistics of traditional high-pressure gas cylinders are a nightmare: constant order tracking, high transport costs, storage space issues, occupational safety risks, and interruptions during cylinder changes. Microbulk solutions eliminate these problems with a smaller cryogenic tank (1,000L – 5,000L) installed at your facility. It offers fewer shipments, higher gas purity, uninterrupted supply, and lower total cost.

Portable Dewar Tanks

These offer flexibility and reliability for laboratories, research centers, universities, dermatology clinics, or low-volume mobile applications. These portable, wheeled tanks (usually between 100L – 500L) allow for the easy transport of cryogenic liquids within the facility and use in low-volume, precise applications. Cryotanx’s Dewar solutions combine laboratory-scale precision with industrial durability.

Working with Cryotanx means starting with a Dewar tank, switching to Microbulk as you grow, and being able to procure a 60,000-liter bulk tank with the same engineering partner and quality assurance when you reach industrial scale.

Not Just a Tank: Complete Cryogenic System Equipment

A cryogenic tank is the heart of a system; but a heart cannot work alone. Your facility needs gas nitrogen (GAN), not liquid nitrogen (LIN). To convert the -196°C liquid inside the tank into usable gas at the correct pressure and temperature needed by your facility, a complete “circulatory system” is required.

The biggest mistake inexperienced buyers make is trying to assemble the system “piece by piece” to cut costs: buying the tank from one manufacturer, the vaporizer from another supplier, and the valves from a third place. This approach almost always results in an operational disaster.

The “Supplier Blame Game” Cycle

When there is a problem with your system (e.g., “I can’t get enough gas pressure” or “The system is constantly freezing”), the inevitable “blame game” begins:

• The tank manufacturer says: “The problem isn’t me, you chose a vaporizer that is too small.”

• The vaporizer manufacturer says: “The problem isn’t me, the tank pressure is low or the valve is faulty.”

The result? While you go back and forth between suppliers, your production stops, and you lose money.

Cryotanx saves you from this cycle. We offer a “compatibility guarantee” and a promise of a “single responsible point of contact” not just for the tank, but for the entire system.

Cryogenic Vaporizers

These pieces of equipment are critical components that convert the cryogenic liquid taken from the tank into continuous gas at the temperature and pressure your facility needs. An incorrectly sized vaporizer can cause insufficient gas flow or excessive icing (freezing), halting your production. Cryotanx provides ambient air, forced draft (fan), or water bath vaporizers optimized for the flow rate required by your process (e.g., 50 Nm³/h or 5,000 Nm³/h), 100% compatible with your system.

Safety Valves and System Accessories

In cryogenic systems, safety is not an “optional” add-on; it is the system itself. An ordinary non-cryogenic brass or steel valve will freeze and lock within seconds when in contact with -196°C. If this valve locks open, you continuously lose gas; if it locks closed, you cause the tank to turn into a bomb due to overpressure. Cryotanx offers cryogenic safety valves, regulators, and filling equipment specially designed and certified to work at -196°C as part of the system, protecting your system and employees.

Working with a single engineering partner (Cryotanx) for all components of your system eliminates compatibility risk, maximizes operational efficiency, and raises your facility’s safety to the highest level.

Industries We Serve: Industry-Specific Solutions

We don’t just manufacture cryogenic tanks; we design optimized solutions based on your industry’s specific needs, regulations, and operational risks. There is no “one size fits all” tank. The hygiene priority of a food plant and the robustness priority of an oil field cannot be met with the same engineering approach.

Cryotanx’s sectoral expertise means we speak your language and know your regulations. This eliminates audit risks or operational risks for your facility.

Oil and Gas Solutions

From well stimulation operations to LNG terminals, the oil and gas sector has some of the harshest working environments. Equipment must withstand extreme temperatures, corrosion, and harsh field environments. Cryotanx offers ATEX/IECEx (explosion-proof) compliant pump and system integrations, high-durability tank designs, and LNG/LIN-based mobile solutions for this sector.

Medical and Pharmaceutical Solutions

For hospitals and pharmaceutical production facilities, “downtime” is not an option. An interruption in a hospital’s medical oxygen (LOX) supply for seconds means the difference between life and death. We are aware of this sector’s requirements for 100% uninterrupted supply, ultra-high purity (UHP), and validation. Cryotanx designs systems with automatic switching featuring a 100% redundancy principle and tanks fully compliant with medical gas standards.

Industrial Gas Solutions

From laser cutting to heat treatment, from metallurgy to chemistry, industrial gases are the heart of production. A drop in gas purity in laser cutting directly affects cutting quality (burrs). Loss of atmosphere control in heat treatment can turn product batches worth millions of dollars into scrap. For these facilities, Cryotanx installs optimized BOR rates and reliable, uninterrupted gas supply systems that maximize production efficiency.

Food and Beverage Solutions

In the food sector, safety, quality, and hygiene come before anything else. Cryotanx offers hygienically designed cryogenic systems with stainless steel surface quality (Ra) suitable for food contact (food-grade). We design and manufacture high-volume LIN (liquid nitrogen) and LCO2 systems compliant with food safety standards, specifically for IQF (Individual Quick Freezing) processes, food shock tunnels, and Modified Atmosphere Packaging (MAP) applications.

Why Should You Work with a Local Cryogenic Tank Manufacturer?

Cryogenic tank acquisition is a Total Cost of Ownership (TCO) investment spanning 20-30 years. You must focus not just on the initial purchase price, but on the entire lifecycle cost. An imported tank may seem attractive initially but often harbors hidden costs and operational risks.

Imported tanks have chronic disadvantages such as high freight costs (especially for large volume tanks), long delivery times that can take 6-9 months, unpredictable customs duties, currency fluctuation risks, and most importantly, slow and expensive after-sales support.

Working with a local manufacturer like Cryotanx eliminates these risks and provides strategic benefits far beyond the “cost” advantage. The real strength of a local manufacturer is not “price,” but “agility” and “accessibility.”

Here are the fundamental advantages of working with the domestic manufacturer Cryotanx:

• Cost and Price Stability: You purge your project of international logistics costs lasting months, customs duties, and currency fluctuation risks. You plan your investment with a clear, predictable, and competitive cost.

• Fast Delivery Times: You don’t have to wait months for ship shipments for your project schedule. Thanks to our domestic production facilities, we offer delivery times measured in weeks for standard tanks, saving you time on your projects.

• Instant Service and Spare Parts Support: This is the most critical factor regarding TCO. When an imported tank breaks down or needs a spare part, you may have to wait for a response from a contact across the ocean and halt production for weeks for the part to arrive. When you work with Cryotanx, your contact is a phone call away. With our expert service teams and local spare parts stock, we intervene in potential problems within hours, not allowing production to stop.

• Engineering Flexibility and Custom Production Solutions: This is the greatest added value of a local manufacturer. Imported manufacturers offer you standard catalog products and expect your facility to fit that product. Cryotanx, on the other hand, produces solutions that fit your facility.

  • Example Scenario: The ceiling of the area where you will place the tank in your facility is low, or the door is narrow.

  • Imported Solution: “Sorry, this is our standard model. Change the location or tear down the wall.”

  • Cryotanx Solution: Our engineering team comes to the site, takes on-site measurements, and designs and manufactures a special “low-profile horizontal tank” or “narrow-diameter vertical tank” for your site. You don’t have to fit the standards. We can produce custom-built engineering solutions tailored to your specific needs.

Our Quality and Safety Standards (ASME, EN 13445, AD 2000)

With high pressure, flammable (LNG) or life-supporting (Medical LOX) liquids, and temperatures of -196°C, safety is not an option but an uncompromising engineering discipline. In the cryogenic tank market, a “non-certified” tank or one with “unclear standards” is legally no different from a ticking time bomb.

As a B2B buyer, the question “Do you have a certificate?” is not enough. The right question should be, “According to which specific standards do you design and manufacture, and are these standards audited by independent bodies?”

Cryotanx’s quality relies not just on our own declarations, but on the approvals of the world’s toughest and most respected independent inspection bodies. Our ability to comply simultaneously with standards from different schools like both ASME (American) and PED/CE (European) proves the global competence of our engineering and quality department.

Our Core Standards and What They Mean for You

The table below summarizes what these complex codes and certificates practically mean for your operation:

Standard / Directive	Scope (What does it do?)	Cryotanx Competence	Meaning for You (Customer Benefit)
ASME Section VIII Div. 1	The global “gold standard” for pressure vessel design, material selection, and production (USA).	U-Stamp Authorized Manufacturer	Proof that your tank has successfully passed and been audited against one of the world’s toughest engineering codes (American Society of Mechanical Engineers).
PED 2014/68/EU (CE)	A legal safety requirement for placing pressure equipment on the market in the European Union (and Turkey).	CE Marking Authority	The guarantee that your tank is fully compliant with laws, meets EU safety regulations, and your facility will pass inspections without issues.
AD 2000 Merkblatt	Detailed German pressure vessel technical rules, often considered even stricter than PED.	Full Compliance	Ensures you have a tank produced with German engineering discipline and attention to detail, possessing an extra level of safety and durability.
ISO 9001:2015	Quality Management System (QMS) standard. Audits the process, not the product.	Certified System	Assurance that every step we take from the moment you order to delivery (from material entry to final test) is traceable, consistent, and bound to high-quality standards.

We are transparent about our quality commitment. You can review all our competencies, including our ASME U-Stamp authorization certificate, CE module certificates, and ISO 9001 documents.

Our Production Process: From Design to Commissioning

The best way to reinforce our identity as a “manufacturer” is to open our factory doors to you and transparently show how a Cryotanx tank comes to life through expert engineering. This process is proof that we are not a “subcontracting workshop” but an “engineering firm.”

Here are the steps of a Cryotanx tank:

Stage 1: Needs Analysis and Engineering (Design)

Everything starts with our expert engineering team listening to your needs (volume, pressure, sector, site conditions). Instead of selling a standard product, we design a solution specific to you.

• Do you need a tank in an earthquake zone? Our engineers perform FEA (Finite Element Analysis) for special support and anchor designs to withstand seismic loads.

• If your process requires 3D modeling and P&ID (Piping and Instrumentation Diagrams), our design team prepares them. This stage guarantees that your tank meets your needs not just today, but also 20 years from now.

Stage 2: Manufacturing and Welding Engineering

Once the design is approved, certified raw materials (ASME/PED compliant stainless steel and carbon steel) enter our workshop. Automatic Submerged Arc Welding (SAW) robots and our internationally certified welders manufacture both the inner and outer vessels of the tank with the goal of perfect union and zero defects. Welding quality is the foundation of the tank’s pressure integrity.

Stage 3: Insulation and Vacuuming

The inner vessel is placed inside the outer jacket. The annular space is filled with our proprietary multi-layer insulation materials (e.g., perlite) to achieve the optimized BOR rate. Then, the critical process that determines the tank’s “performance” begins: vacuuming. Using high-capacity diffusion pumps, the space between the two vessels is brought to a deep vacuum (<50 microns) in a process lasting for days.

Stage 4: Quality Control and Test

Quality control is applied at every stage of production, but this is where the tank is finished. Standard tests we apply to every tank with a zero-defect goal:

• Radiographic Test (RT / X-Ray): To view the internal structure of critical weld seams and detect potential cracks or pores.

• Hydrostatic Pressure Test: Testing structural integrity by filling the tank with water up to 1.5 times the design pressure.

• Helium Mass Spectrometer Leak Test: This is the test that determines our authority. It is the most sensitive way to test vacuum integrity. Helium is the second smallest atom in the universe. If your vacuum can keep even Helium out, this means perfect insulation and a vacuum life that will last for decades.

Stage 5: Shipment and Commissioning

The tank, having passed all tests, is shipped to your site with special transport protocols and commissioned by our expert teams.

This transparent and rigorous process allows us to confidently meet even our customers’ most complex Custom Production Solutions requests.

After-Sales Support: We Don’t Just Produce, We Sustain

Purchasing is not the end of your relationship with Cryotanx, but the beginning. Cryogenic tanks are not “fit-and-forget” equipment. They require periodic maintenance for legal obligations (such as safety valve tests) and to maintain the tank’s performance (BOR).

We are a local and accessible service partner standing behind every tank we produce throughout its 20+ year economic life.

Installation and Commissioning

Safely integrating your tank into your multimillion-dollar facility is a critical step. Our expert teams guarantee that your tank is mounted correctly on-site, your system operates safely, and your personnel receive the necessary training.

Periodic Maintenance and Inspection

Ensuring your facility’s safety and legal compliance is our duty. We proactively support you for periodic tank inspections and safety valve tests/replacements, which are mandatory under the pressure vessels regulation.

Refurbishment and Upgrading

This is our most key service transforming Cryotanx from a supplier into a “solution partner.”

• Scenario: You have a 20-year-old tank from a competitor brand in your facility. Its vacuum has failed (the outside is icing up), and the BOR rate has increased significantly (constant gas venting). You are preparing to allocate a €100,000 budget for a new tank.

• Cryotanx Solution: “No need for a new tank.” Our expert team can “re-vacuum” your existing tank (regardless of the brand) on-site or at our facility, modernize its valves, and gain you another 10 years of life. With this operation, you avoid a €100,000 capital expenditure and return your tank to its first-day performance at a much lower cost.

Do not throw away your old or inefficient tanks. Let us give your tank a new life with our vacuum renewal, modernization, and capacity increase services.
