P200 series ensure reliable, precise and consumption-optimised cooling with the aid of a central water circuit. Starting with 4 RU (rack units) they have a particularly compact design. Alternatively, they are also available as desktop units.
A stainless-steel plate heat exchanger is integrated between the cold water circuit towards the connected devices (secondary circuit) and the central cooling water circuit (primary circuit). The functional requirement is a temperature difference of at least 5°C between the two circuits. The temperature is regulated automatically using a motive proportional control valve. It controls the water flow into the primary circuit as a function of the tank temperature, thereby ensuring a low water consumption. The cooling water temperature remains continuously constant with a maximum deviation of +/- 0.2 K and the refrigeration capacity, which is variable between 1 and 20 kW, is automatically adapted to the load requirements.
