CTC EcoAir 520M


The design is based on the tried and tested EcoAir 400 range, so it also has the same high-quality finish and good design. The focus of development was to retain the popular properties that characterise the other products in the EcoAir family. The product has been fitted with a new speed-controlled compressor that adapts effectively to your own and your property's needs. The result is a product with very high COP values and low sound levels. The CTC EcoAir 520M has on-demand automatic defrost, which provides more heat and a longer useful life. The CTC EcoAir 520M is of course fitted with a heated condensation water tray.
