The Polycold MaxCool 2500 L cryochiller effectively captures water vapour, which comprises 65% to 95% of the residual gas in high vacuum systems.
Water vapour 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.
When added to your vacuum system, the MaxCool Cryochiller can dramatically reduce pumpdown times and increase product throughput. The MaxCool will pump water vapour 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.
