PGC Gas Chillers

A closed-loop refrigeration system that cools a non-recirculating gas stream

Edwards Polycold® PGC Gas Chiller requires no pre-cooling

PGC Gas Chillers are closed-loop refrigeration systems that cool a non-recirculating gas stream using a refrigerant to gas tube-in-tube heat exchanger.

Using the Edwards Polycold auto-refrigerating cascade technique with a mixed refrigerant, PGC Gas Chillers enable you to cool dry gas to temperatures between -75°C and 125°C without sacrificing high flow rates.

PGC Gas Chillers are suitable for many applications, including thermal testing of electronics, cold gas venting of vacuum chambers, rheology, and low-temperature characterization of materials.

They are the most cost-effective systems available for cooling a gas stream in an ultra-low temperature range (-75° to -125°C/ -103° to -193°F/198 to 148 K) without the cost, risk or inconvenience of liquid nitrogen.
