Heat Exchanger Design INC

These heat exchangers were designed and manufactured by Heat Exchanger Design Inc. for NASA and are engineered for cryogenic applications utilizing liquid nitrogen to cool liquefied natural gas (LNG). Designed to operate at temperatures as low as -320°F, the units are built to perform reliably under extreme thermal conditions while maintaining high efficiency and structural integrity.

The system supports precise temperature control and heat transfer within LNG processing applications, where maintaining cryogenic conditions is critical for safe handling, storage, and transport. Fabricated from materials specifically selected for low-temperature performance, the units are engineered to meet stringent industrial and aerospace-quality standards.

CURRENT PROJECT:

This is a LNG Cryogenic Heat Exchanger is a high-performance thermal management unit engineered for NASA’s operation. Designed to operate at temperatures near –162 °C, it enables efficient heat transfer between liquefied natural gas and liquid nitrogen while maintaining exceptional reliability under extreme aerospace conditions.

Built from lightweight, high-strength stainless steel alloys, the exchanger features plain tubes for maximum heat transfer efficiency and minimal pressure drop. Its vacuum-jacketed insulation minimizes boil-off losses, and precision-welded joints ensure leak-free performance during thermal cycling.

Compact, durable, and mission-ready, this system supports NASA’s advancements in cryogenic fuel handling, clean-propulsion, and sustainable deep-space energy applications.
