S-THERM 4 OUTDOOR UNITS
Outdoor units of S-THERM 4th generation are different from the 3rd generation mainly because of the used refrigerant. Units are prefilled with single-component refrigerant R32 which is more gentle to the environment. Innovated refrigerant circuit solution with economizer and intermediate enthalpy adding through gas injection helps to achieve better operating range, improving both capacity and efficiency and regulate compressor temperature.
