The components of a heating and cooling system are exposed to degradation caused by the impurities that circulate in the thermal medium. If the impurities are not removed as necessary, they may cause blockages and seizing of the pumps, lower efficiency of the heat exchangers, unreliable valve operation and insufficient heat exchange.
In the specific case of heat pump systems, the use of a magnetic filter dirt separator is recommended. The impurities may actually put the already small inner channels at risk of blockage, or prevent the internal adjustment devices from working properly. As the heat pump is a generator employing low temperature differences, even small changes in flow rate may adversely affect its performance. The greater the filtering action of the magnetic filter dirt separator, the longer the high efficiency of the heat pump systems will be maintained.
