Water-water heat exchanger 1 to 25 kW
Chilling is performed by passing the laser water through a heat exchanger which is also attached to primary (house) water. Functional requirement: a ∆t of at least 5 °C is necessary between the secondary circuit (laser water) and the primary circuit (house water). Temperature control via a proportional valve.

Theory of operation:
Using a stainless steel heat exchanger plate, the coolant water in the secondary circuit is cooled with tap water in the primary circuit. A servo driven proportional valve adjusts the primary water flow according to the tank temperature, thus optimising water usage. This control circuit enables a very constant coolant water temperature of < ± 0,2K to be maintained and prevents pressure surges in the system. Using proportional control, the cooling capacity automatically adjusts to the load requirements.
