Working from Chamber drawings or specification, a custom designed cryocoil can be fabricated to perfectly fit your chamber and deliver optimal vapor trapping and heat removal performance
Cryocoils are made from copper tubing (stainless steel is also available) and constructed with a stainless steel feedthrough.
Many different coil shapes and configurations allow for optimum efficiency of your cryosurface.
Cryochiller Digital Control
The advanced digital control package operates at 24V, has battery back-up, and is fully CE compliant. Two 20 character 1/2” high backlit read-outs allow for easy reading and rapid scrolling through all available monitor points.
Convenient interface capability for RS-232, RS-485 or Ethernet (TCP/IP) allows for easily adapted system controls or external data-logging. This advanced control package is placed inside the main unit housing creating a smaller overall system footprint. The flexible capabilities of the controller remove the need for additional and costly system control options or specialized interface modules. A 37 pin remote connector is included for those wishing remote manual or analog system control.
(Available separately or as part of the cryocoil)
The dual pass feedthrough gives access to the chamber while maintaining the thermal isolation between the feed and return tubing. On the external side, couplings mate directly with the refrigerant line. On the chamber side, the feedthrough is braised to the cryosurface lines.
Cryochiller Refrigerant Line
The “refrigerant line” contains both a feed line and a return line of copper tubing with stainless steel couplings to mate with the cryochiller and with the feedthrough. The refrigerant line is protected with foam type thermal insulation to minimize heat loss and protect against exposure to open air.
Dual Circuit Cryochillers
All five models are available in a dual circuit configuration, in which the systems provide independent control and cooling of two surfaces. Common configurations are two cryocoils or a cryocoil and a cryobaffle. Each circuit can cool or defrost independently with only a modest effect on the other circuit. For cryobaffles protected by a gate valve, the baffle can be constantly maintained at cryo-temperature while the in-chamber cryocoil is cycled for expected process time improvements. Each circuit is independently controlled and monitored.
