The QBE TOTEM serie is specifically designed to meet the application requirements of the laser applications by offering a precise control of the chilled water temperature during long operational periods with different thermal load requirements. It is equipped with two pumps for two different users at different temperatures (water source to cool the laser source and water source to cool the optics).

The refrigeration circuit is designed to meet a fine regulation of the outlet water temperature (± 0.5 K), made with an electronic hot gas bypass valve (01), able to manage widely variable thermal load trends and providing a constant temperature of the chilled water (source side).

The water temperature dedicated to the optics cooling is managed by a 3-way valve .(02)that guarantees a precise control of the outlet water temperature with a tolerance of ± 1 K.

QBE TOTEM series units have been designed with the smallest footprint possible and are equipped with wheels for an easy positioning. The hydraulic connections are located below in the rear side and are equipped with shut-off valves.
