We recommend using Frimec – Inverter outdoor condensing units as a cooling (heating) source for the HVAC units we manufacture. FRIMEC units are environmentally friendly, give good noise performance and stand out for their reliability and easy installation. They are equipped with an inverter compressor, which allows continuous power control depending on the actual demand. The FRIMEC condensing units of F5LCY and F5MSDC lines are supplied in the following version – a heat pump, including an injection valve or a capillary, with a 4-way valve – and are pre-filled with the R410A /R32 cooler). We will be happy to provide you with more detailed information on request or as part of a technical offer and a quotation.
