Hi-FLEXi S series heat recovery unit can enable simultaneous operation of cooling and heating within a single refrigerant circuit, achieving energy savings through heat recovery. Besides, a hydrobox is availiable to be connected in the refrigerant system, providing cooled or heated water for fan coils, radiators, the floor heating and domestic hot water tanks.

New generation scroll compressor is now patented with higher performance capability vapour injection technology, increasing capacity up to 25% compared to conventional scroll compressor with same amount of power consumed.

With the 360° refrigerant cooling technology, Hi-FLEXi S Series will remove the heat from the main PCB, making inverter module and electrical box stable and efficiency. New and integral heat sink can help to improve the electrical reliability of the unit when it is running under high ambient temperature.

In winter, our products can achieve continuous heating by rotational defrost, providing with a more comfortable and warmer indoor environment.

Compared with conventional 10RT EEV with 480 steps, dual 20RT EEV with 3000pls can better reduce pressure loss and improve performance.
