Basic construction and technical description

Common features

All Series WK water circulation coolers have a refrigeration system in the lower part of the unit, employing a
sealed compressor, air-cooled or water-cooled condenser with refrigerant R 134a resp. R 404 A to cool the
liquid in the liquid tank through an evaporator.

In case of water-cooled version the required cooling water flow is optimized in dependence of the
condensation pressure, that means the water consumption is dependent on the dissipated capacity. It is
between 200 and 2000 L/h according to device, cooling water temperature and load. The cooling water
temperature must not exceed 25°C. Cooling water pressure 2,5...10 bar is necessary.

Immersion pumps of different capacity circulate the liquid (usually water) inside the bath and pump it
outside and through the external equipment to be cooled.

The types WK 7000, WK 10000 und WKL 7000, WKL 10000 have a separate pump that charges a plate
heat exchanger. Through that the cooling capacity is independent of the discharge flow through the external
circuit.

A temperature probe inside the bath measures the temperature which is indicated digitally. The temperature
setpoint is selected digitally. The controller controls cooling by switching the refrigeration compressor on
and off (from WK 4600 through magnetic valves in push-pull circuit).

An intelligent delay logic prevents the compressor being overloaded due to excessive switching frequency.

In the configuration level an alarm switching point can be adjusted. When exceeding this value the luminous
diode K2 goes out and the neutral contact of the plug connection alarm at the back of the unit opens. This
means that the alarm contact is open even in case the unit is switched off. The contact is closed only 60 sec
after switching on the mains switch.
If the temperature of the liquid is lower than the chosen alarm switching point the contact is closed which
means that contacts 1 and 2 of the plug connection 15N are closed. Maximum contact load 30 V, 2 A.
