CryoProbe Installation BRUKER 87 (93)
the ‘pneumatic gas’ used for operating valves inside the CryoCooling Unit or with
the helium gas circulated through the CryoProbe for cryogenic cooling.
VT Interface Box
A small box with two cables which interfaces heater and temperature sensor be-
tween CryoProbe and VT unit.
VT unit
A device that controls the flow and temperature of the VT gas, e.g. a B-VT3000.
Water chiller
The water-cooled versions of the He Compressor require cooling water to remove
7.5 kW of heat. A water chiller is recommended if no closed cycle cooling water is
available in the laboratory building.
‘Split-type’ water chillers are composed of two units: a main unit that pumps and
cools the ‘primary’ water cycle by exchanging its heat to a ‘secondary’ cycle, and
a radiator unit that fans the heat from the secondary cycle into the air, usually at
the outside of the building.
