Decalcifying the cooling water circuit
At regular intervals of 3 months or longer (depending on the water hardness / degree of contamination of the cooling
water), the water-cooled condenser must be decalcified or cleaned.
Required equipment:
Two containers of 10 to 20 liters.
Use a suitable pump (drum pump) or possibly use hose with a funnel with funnel located above the cool-
ing water inlet.
Hose between container, pump and cooling water inlet and also between cooling water outlet and container.
Via the water inlet hose, fill the device with decalcifier (pump or hose). Set the set value to 10 °C; after the chiller
starts the water circuit can be filled. Circulate the decalcifier with the pump or continue to top up the decalcifier.
Allow the decalcifier to have an effect (see table below). Then drain the device. Again connect the device to the water
supply and thoroughly flush it out (see table below).
Continue with the pumping process until the foaming reaction decays. Generally, this is achieved
after about 20 to 30 minutes.
