PREMIUM PREHEAT 250 CS/CL A Product description Premium Preheat 250 CS/CL A is suitable in dwellings where a combination of heat recovery ventilation and supply of comfort heating or cooling with the supply air is desired. Before the fresh air is drawn into the house, heat is supplied to it in the counter current heat exchanger - heat recovered from the extract air. Then additional heat is supplied to the supply air by the heat pump and thereby it contributes to the home heating. If it is desired that cooling is supplied to the air instead, this is also possible. The supply air filter ensures that dirt and pollen is not brought into the house. Premium Preheat 250 CS/CL A can deliver an air volume of up to Premium Preheat 250 CS/CL A is an air-air heat recovery ventilation heat pump which is equipped with the following: An aluminum counter current heat exchanger, a heat pump with cooling function, a pre-heater integrated in the heat pump, supply and extract air fans, F7 supply air filter, M4 extract air filter, and complete Optima 301 automatics with a control panel. Premium Preheat 250 CS/CL A can be delivered with the following accessories: -- Electrical reheater for Ø160 mm duct appr. 325 m3/h at an external pressure of 100 Pa.

The capacity lines are based on an average of the supply and extract mass flow in a unit. The red line in the chart indicates a total power consumption for both fans and the control of 1620 J/m³ (PHI). The curve shows the average external pressure, which is available at a given air volume. Total power consumption Power consumption (W) For both fans and control.
