liquid nitrogen generator 1

Small Integrated Liquid Nitrogen Generator

The small liquid nitrogen machine is a plug-and-play liquid nitrogen solution.

It adopts the mixed-refrigerant Joule-Thomson (MRJT) cooling technology. Based on the regenerative multi-component mixed-refrigerant throttle refrigeration cycle, it selects pure components with high, medium, and low boiling points to form a multi-component mixed refrigerant from ambient temperature to the target cooling temperature, realizing the relay matching of effective cooling temperature ranges for each boiling-point component.

It is a refrigerator capable of efficiently achieving a cooling range of -40°C ~ -196°C.

Medium-sized Liquid Nitrogen Equipment

The medium-sized liquid nitrogen generator is a skid-mounted liquid nitrogen solution. It adopts the mixed-refrigerant refrigeration MRJT process, which is based on the recuperative multi-component mixed-refrigerant Joule-Thomson (MRJT) refrigeration cycle. From ambient temperature to the target refrigeration temperature, it optimally selects pure components with high, medium, and low boiling points to form a multi-component mixed refrigerant, achieving the relay matching of the effective refrigeration temperature ranges of each boiling-point component. It is a refrigeration machine that can efficiently achieve the temperature range of -40 to -196°C.
