The S Heat Recovery Series maximizes energy utilization by enabling simultaneous cooling and heating in heat recovery mode, while also functioning as a two-pipe system. A water module can be seamlessly integrated into the refrigerant system to support floor heating, domestic hot water (DHW), fan coils, and radiators—delivering a more comfortable and versatile indoor environment.
All-in-One Renewable Energy SolutionHi-FLEXi S series heat recovery unit supports simultaneous cooling and heating within a single refrigerant circuit, promoting energy efficiency through heat recovery. It can also connect to a hydrobox, providing heated or cooled water for fan coils, radiators, floor heating, or domestic hot water systems. |
