Cryochillers, Cryopumps
& Cryogenic Vacuum Systems
Understand the equipment that removes water vapor, captures gases and creates reliable cryogenic cooling—from cryocoils, pump arrays and cold heads to compressors, refrigerant or helium circuits, controls and regeneration—then connect to the correct YTI repair, refurbishment, recharge, rental, parts or fleet-support page.
Equipment Category Hub
Two cryogenic technologies—one connected vacuum process
Cryochillers and cryopumps both use very low temperatures, but they solve different vacuum problems. A cryochiller commonly cools a cryocoil or Meissner coil to trap water vapor and shorten chamber pump-down. A cryopump uses internal cryogenic arrays to capture gases and vapors as a high-vacuum pumping stage.
This page organizes those equipment families and the support hardware around them. Use it to compare system roles, understand the complete cryogenic chain, identify manufacturers and connected equipment, and continue to YTI’s focused pages for repair, refurbishment, refrigerant recharge, preventive maintenance, rentals, used equipment, component stocking or fleet planning.
Cryogenic Equipment Families
Cryogenic systems YTI supports
The correct equipment path depends on what the cryogenic system is expected to capture, the vacuum level required, the process load, cycle time, regeneration needs and the utilities available at the chamber.
Cryochillers, Cryocoils & Meissner Coils
Refrigeration systems that cool an in-chamber or external coil so water vapor and other condensable vapors collect on a cold surface. These systems improve pump-down, reduce residual moisture and support more repeatable coating cycles.
Cryopumps & Cryogenic Arrays
High-vacuum pumps with staged cold surfaces that capture gases and vapors inside the pump body. Performance depends on cold-head capacity, array condition, compressor support, chamber load and a reliable regeneration sequence.
Cold Heads & Refrigeration Modules
Cold-head, displacer, valve, seal and thermal-interface assemblies that create the low-temperature surfaces used by cryopumps and other cryogenic equipment.
Compressors, Lines & Gas Circuits
Refrigeration compressors, helium compressors, adsorbers, flexible lines, fittings, cooling circuits and pressure-management hardware that keep the cold-producing equipment operating correctly.
Legacy, Mixed-Brand & Chamber-Integrated Systems
Older or modified packages where cryogenic hardware, chamber interfaces, controls, replacement parts and other vacuum equipment must be evaluated together.
Cryogenic System Architecture
Six equipment layers behind cryogenic performance
Cooling capacity and vacuum performance are created by the entire chain. A healthy cryocoil or cryopump can still underperform when the process load, compressor, gas circuit, chamber interface, controls or regeneration strategy limits the system.
Chamber & Process Load
Chamber volume, water-vapor load, outgassing, process gases, target base pressure, cycle time, heat load and the location of the cryogenic surface.
Cold Surface
Cryocoil, Meissner coil, first-stage array, second-stage array, cryopanel or adsorbent surface where gases and vapors are captured.
Cold-Producing Assembly
Refrigeration circuit or cold head, including displacer, valves, seals, thermal interfaces and the components that create usable low temperature.
Compressor & Working-Gas Circuit
Refrigeration compressor and refrigerant charge for cryochillers, or helium compressor, adsorber and flexible lines for compressor-driven cryopumps.
Controls, Sensors & Regeneration
Temperature measurement, pressure protection, alarms, valves, heaters, purge, regeneration logic, interlocks and operator controls.
Utilities & Vacuum Interfaces
Cooling water, electrical service, ventilation, chamber ports, isolation valves, vacuum seals, support structure, service access and connected pumping equipment.
Application & Integration
What determines the right cryogenic equipment path
Cryogenic equipment should be matched to the process objective and complete vacuum system. These factors determine whether the need is water-vapor trapping, high-vacuum pumping, deeper service, an integration change or a different support strategy.
Process Gas & Vapor Load
Water vapor, condensable load, noncondensable gases, process byproducts, outgassing and contamination determine what the cold surface must capture.
