VivAir Uni Comfort SDH 19 is the new range of air conditioners that use R32 refrigerant gas which offers greater energy efficiency , a lower impact on the climate (Global Warming Potential - GWP= 675) and a lower amount of charge required compared to air conditioners that use R410A gas.
Thanks to the use of the new R32 gas, the new Hermann Saunier Duval air conditioners are already in line with the achievement of the objectives established by the new regulation on fluorinated gases issued by the EU in 2015, which prohibits the use of refrigerants with a GWP higher than 750 in single split air conditioners containing a refrigerant charge below 3 kg.
VivAir Uni Comfort SDH 19 is available in Dual, Trial and Quadri versions with powers from 4.1 kW to 8 kW in cooling, with energy class A++ in cooling (SEER up to 6.3) and in heating A+ (SCOP equal to 4 ,0) on all models.
The new range offers various functions to improve the comfort of your home: " I Feel " function to offer the desired temperature where the remote control is located, " Turbo " function to reach the desired temperature in the shortest possible time, flow direction adjustment of air vertically and Sleep function to minimize noise at night.
All available functions can be easily set by the supplied remote control, which is easy to use and features a large display to indicate the current operating status.
