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. The new R32 gas VivAir is the new range of Hermann Saunier Duval air conditioners that use R32 ecological refrigerant gas. Thanks to the use of the new gas it is possible to obtain many advantages such as greater energy efficiency, a lower impact on the climate and a lower amount of charge required compared to air conditioners that use R410A gas. R32 gas is a safe gas, tested and already widely used for domestic applications in many foreign countries for several years. What impact does it have on the climate? The acronym GWP (Global Warming Potential) is used to express the influence that a specific refrigerant would have if released into the atmosphere. The higher the GWP value, the greater the negative effect of that refrigerant on climate and global warming. The new R32 refrigerant has a GWP of approximately 675, which corresponds to approximately one third of that of R410A gas (GWP=2088). Ready for the new EU Standards The new VivAir range is already in line with the achievement of the objectives established by the new directive No. 517/2014 on fluorinated gases issued by the European Union, which prohibits the use of refrigerants with a GWP higher than 750 starting from 2025 in mono-split air conditioners containing a refrigerant charge below 3 kg. Multisplit air conditioner with R32 ecological gas New R32 refrigerant gas Dedicated MultiSplit indoor units: wall, cassette and floor/ceiling Energy efficiency class in cooling up to A++ "I Feel" function with remote temperature sensor on the remote control Sleep function to minimize noise at night. High performance with a reduced environmental impact Environmentally friendly, because it has a low GWP index Less refrigerant than units with R410A More energy efficient than R410A Safe and reliable Product Guarantee: All products for sale on our site are new and packed. The warranty on this item is 24 months from the date of purchase.
