Ultra-low temperatures -50 to -100℃ (-58 to -148℉) PascalAir - air cycle system

PascalAir

Since air acts as the refrigerant, not an HFC, there is no refrigerant-induced impact on the global environment. Furthermore, in the ultra-low temperature range from -50 to -100℃ (-58 to -148℉), it is possible to reduce CO₂ emissions and achieve energy savings of up to 50 percent compared to conventional vapor pressure refrigeration systems.

NH₃/CO₂ cascade refrigeration system

An environmentally friendly cascade refrigeration system that uses ammonia as a refrigerant on the higher-temperature side and CO₂ on the lower-temperature side. As only CO₂ is supplied as the secondary refrigerant, the risks associated with ammonia are minimized. This product is suited for use in situations where low temperatures are needed, such as freezers that have internal temperatures of -40℃ (-40℉) or lower. By controlling the number of refrigeration compressors on the high-and low-temperature sides, it is possible to operate the system in line with the required load.
