  • Ultra efficient

    Year-round system efficiency enhancement of chilled water and hot water loops by eliminating glycol mixing.

    While in simultaneous mode, combined heating and cooling efficiencies up to 28 EER can be achieved.

  • Move decarbonization forward

    Replace boilers that burn fossil fuels with an energy efficient electrified heating source. Thermafit multi-pipe units enable electric heating and cooling to get you one step closer to making net-zero goals happen and meet changing building codes and regulations for electrification.

  • Ultimate flexibility for cooling and heating

    Multipipe design provides simultaneous heating and cooling with ultimate versatility. 6-pipe design featuring three independent loops eliminating the need for extra heat exchangers and pumps. Each loop operates on its own compressor for reassuring redundancy and tighter fluid control. This design saves space by combining heating and cooling duties and eliminating glycol mixing.
