Manufacturing Plant
State of art heat exchangers (L-shaped U-shaped)  used for heating/cooling in DX applications was specially designed for R-290 (Propan) refrigerant. Thanks to grooved - copper tubes , louvered fins and special (patented) deflectors  We  are able to increase efficency/cooling capacity.
Our heat exchangers custom projects not only include number of rows and circuts , fin space, tube diameter and R-290 refrigerant side / air side parameters but also air/water heat pump shape and EC fan localisation.  
PCT patent (also ready with R-32, R-1234,NH3,CO2 refrigerants)  changes refrigerant expansion inside the heat exchanger tubes , thats why our heat exchangers are so powerfull. Special design of refrigerant distributor guarantee lubricant recover even in inverter designs.
