Cryogenic Vaporizer & Heat Exchanger Suppliers & Manufacturers
Cryogenic vaporizers and heat exchangers manage the thermal side of the cryogenic value chain. Vaporizers convert liquefied gases back to gas phase at required temperature and pressure for downstream use. Heat exchangers transfer heat between process streams inside liquefaction plants, air separation units, LNG regasification terminals, and hydrogen liquefaction facilities. Together they define the energy efficiency and product quality of most cryogenic installations.
Vaporizer families include ambient air vaporizers using atmospheric heat exchange, water bath and steam vaporizers for high continuous flow, electric vaporizers for precise temperature control, submerged combustion vaporizers for LNG peak-shaving, and open-rack seawater vaporizers for large LNG regasification terminals. Heat exchangers include brazed aluminum plate-fin exchangers (the workhorse of air separation and LNG liquefaction), coil-wound heat exchangers for large-scale LNG trains, printed circuit heat exchangers for compact high-pressure duty, and shell-and-tube designs for auxiliary services.
This directory lists cryogenic vaporizer and heat exchanger manufacturers worldwide as a combined listing. Each supplier profile covers equipment types, thermal duty ranges, design pressures, cryogen compatibility, certifications under ASME BPVC Section VIII, PED, or ALPEMA for plate-fin heat exchangers, and lead times.
Procurement teams evaluating suppliers typically weigh thermal capacity across ambient conditions, discharge temperature control, defrost and switching arrangements for ambient air vaporizers, exchanger effectiveness and pressure drop, plate-fin design flexibility for multi-stream duty, ALPEMA compliance for critical exchangers, and delivery lead times which extend to 78+ weeks for large brazed aluminum exchangers. Filter suppliers by country, equipment type, cryogen, or capacity.
Frequently asked questions
What is a brazed aluminum plate-fin heat exchanger?
A compact cryogenic heat exchanger built by stacking aluminum plates with finned separators and brazing the assembly in a vacuum furnace. Plate-fin exchangers handle multiple streams in a single core, achieve very low temperature approaches, and dominate air separation cold boxes, hydrogen liquefaction, and LNG plants. Design and manufacturing follow the ALPEMA standard.
What is an ambient air vaporizer?
A vaporizer that uses natural convection over finned aluminum tubes to absorb heat from surrounding air, requiring no energy input beyond pumping. Economical for continuous or intermittent low-to-moderate flow. Performance drops with humidity, cold weather, and ice accumulation, so pairs or trios operate in alternating service and defrost cycles.
Which vaporizers are used at LNG regasification terminals?
Open-rack seawater vaporizers dominate large baseload terminals in coastal locations. Submerged combustion vaporizers are used for peak-shaving and where seawater is not available. Intermediate fluid vaporizers use a secondary loop of glycol or propane to isolate seawater from LNG for improved reliability.
What is the ALPEMA standard?
The Aluminium Plate-fin Heat Exchanger Manufacturers Association Standards define design, manufacture, testing, and installation practices for brazed aluminum plate-fin heat exchangers. Fifth edition is current. Compliance is expected for cryogenic exchangers in air separation, LNG, and hydrogen service.
What are typical lead times?
Standard ambient air vaporizers: 12 to 20 weeks. Large steam or water bath vaporizers: 24 to 40 weeks. Brazed aluminum plate-fin heat exchangers: 40 to 78 weeks and sometimes longer for large ASU cold boxes. Coil-wound exchangers for large LNG trains: 78 to 130 weeks.
