Hi,
Just a reminder that ice formations that grow from the chamber floor of any
cryostat are not directly caused by a frost buildup. They are most commonly
caused by a leak or blockage somewhere in the defrost system. If you check
above the ice formation you can usually detect the cause of the problem.
You will notice these types of problems more during times of heavy use or
high humidity because there is more frost on the fins, creating more water to
remove when the defrost system is activated. If the water cannot be directed
correctly through the defrost pan and out the tubing it will find another way
to travel--usually creating a stalagmite type of growth on the chamber floor.
