MaxCool 4000 H Cryochiller

Maximum water pumping speed for increased throughput

Water Vapour Pumping

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 220,000 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 vapour 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.
