Brooks Polycold® 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.

MaxCool Cryochillers

Polycold MaxCool Cryochillers are closed loop cryogenic refrigeration systems that provide up to 2,500 watts or 4,000 watts of cooling, respectively. These cryochillers can be used to capture water vapor and other condensable substances by freezing them onto a cold surface such as a cryocoil or chevron baffle. MaxCool cryochillers are also used to cool and heat objects such as electrostatic chucks used in semiconductor wafer processing.

MaxCool Data Sheet

Water Vapor Pumping

The Polycold MaxCool 2500 L cryochiller effectively captures water vapor, which comprises 65% to 95% of the residual gas in high vacuum systems. Water vapor is typically the most reactive contaminant present. With the MaxCool Cryochiller, you can expect to increase product throughput in your existing system 20% to 100% and improve quality of deposition.

The MaxCool Advantage

  • High-vacuum pumpdown time cut by up to 75%
  • High-speed pumping of water vapor: 10,000 to 140,000 l/sec in the workspace
  • Increased product throughput of 20% to 100%
  • Lower water vapor partial pressure during processing for higher film quality, better adhesion and more reproducible deposition
  • Superior in cost/performance to liquid nitrogen cooled Meissners
  • Minimize cost of ownership with power management
  • High capacity cooling and heating for a wide variety of processes

When added to your vacuum system, the MaxCool Cryochiller can dramatically reduce pumpdown times and increase product throughput. The MaxCool will pump water vapor within minutes from “start” and can defrost in less than four minutes, giving true fast-cycle capability. It also has an option called Rapid Cool to Cool which eliminates the waiting period after defrost. For your system, this means more production cycles per shift.

Using patented Polycold® refrigerant mixtures, the MaxCool works on the principle of Meissner trapping. Water vapor is captured by condensation on a cryogenically cooled surface, called a Meissner coil. The Meissner (cryocoil) is mounted directly in the vacuum chamber so conductance is not limited by ports, manifolds, valves, and baffles. The cryocoil is easy to install and can be adapted to fit any system.

It does not need a high vacuum valve.

MaxCool Cryochillers are the most cost effective upgrade that you can add to any diffusion-pumped, turbo- pumped, or helium-cryopumped system.

MaxCool Cryochillers are compliant with European Application Refrigerants (EC 1005/2009), the Montreal Protocol, and the US EPA SNAP.
