Operating principle
The BCU05 is a cooling unit that reduces the temperature of an air input by typi-
cally 65°C.
Freon gas is circulating around an external heat exchanger within a completely
sealed system. The unit is designed to be operated in conjunction with the
BVTXX00. The VTU provides the gas input for the BCU05 as well as controlling
the sample temperature. When operated in conjunction with a BTO2000, sample
temperature stability of ± 0.01°C/°C can be achieved (with BVT3X00).
