Telemark Cryogenics Microprocessor Based Cryochillers
a. The surface should be clear of any moving parts within the vacuum
system.
b. No closer than 25mm to any chamber wall and out of direct line of sight
with heaters or other forms of heat (magnetrons etc) – if this is
unavoidable then the surface can be effectively shielded by aluminium foil.
c. In systems where there is a great deal of water evolved such as roll / web
coating of paper and other materials or where the film is moisture
sensitive process improvements can be made by placing the cryo-surface
close to the point of moisture generation e.g. The unwind area of a web
coater.
d. Consideration should be given to where the trapped water goes once the
surface has been defrosted a drain may be required if there is a lot of
water.
e. Do not place refrigerant couplings within the vacuum system.
