PGC Gas Chillers

The Brooks Polycold® Gas Chillers cool compressed dry gases, such as nitrogen, argon or air, from ambient to cryogenic temperature without 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 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.
