Product innovations
New reversible heat pumps with propane
Alongside the standard solutions from Secon, our range now also includes reversible Climaveneta units from Mitsubishi Electric. Developed and manufactured in Europe, they use the environmentally friendly natural refrigerant propane (R-290). Safe and efficient to operate, these units feature scroll compressors, separate cooling circuits for each compressor and fans with diffusers to reduce noise levels.
