Function of the Klump & Koller Debris Filter System Type TA (patented)
The Debris Filter System type TA continuously removes all debris that otherwise might clog the heat exchanger and condenser tubes. A screen monitor (8) with limit contacts controls the degree of contamination of the Debris Filter. As soon as the highest permissible degree of contamination is reached, the waste water valve (10) opens automatically and the backwash rotor (4) is activated. The low pressure at the end of the backwash pipe (6) causes a reverse direction of flow (5) of the cooling water in the area of the backwash rotor filter segment (3). The filter element is released from pressure through the backwash rotor channel (3). Therefore a strong backwash flow (4) separates the debris from the filter surface and transports the debris to the backwash rotor channel (3). From here the separated debris is channelled off to the backwash pipe (6) and is disposed of by the waste water valve (10). Regardless of the degree of contamination the Klump & Koller Debris Filter System is also backwashed periodically.
