Dual Circuit Cryotraps

The TVP2000 and TVP3500 are available in dual circuit models 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 minimal 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.

Dual Circuit Models are:
TVP2000D
TVP3500D

Model and Accessory Selection

Selection of the correct model of the Telemark TVP depends upon two primary factors: The amount of water vapor that needs to be trapped and the total heat load the system needs to manage.

The TVP2000 deals with heat loads up to 2000 watts and can trap up to 90,000 l/sec of water vapor at a variety of vacuum depths. The TVP3500 can manage a combined heat load of 3500 Watts and can trap up to 220,000 l/sec.

When determining the optimum vapor trapping capability to significantly improve pump-down times, a preliminary goal should be to achieve at least four times the current water vapor trapping capability of your vacuum pump.

Total heat load is a combination of: 35 watts/square ft. of cryosurface, 8 Watts per linear ft. of insulated refrigerant line, "latent" heat loads which are extensive at shallow vacuum depth but can be ignored at 10^-4 or below, and in-chamber heating of:

Feedthroughts
(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.

Single pass feedthroughs are also available.

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 TVP system 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.
