Water Vapour Pumping 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. The MaxCool Advantage High-vacuum pumpdown time cut by up to 75% High-speed pumping of water vapour: 10,000 to 140,000 l/sec in the workspace Increased product throughput of 20% to 100% Lower water vapour 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 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.
