At the State Airport of Lemnos “Hefaistos” an upgrade of the central air conditioning system was carried out with the installation of 2 air-cooled heat pumps AERMEC type NRB1400XHAV00 with a total installed cooling capacity of 800KWatt.

The heat pumps are highly energy efficient with a seasonal ESEER factor of 4.11 and the maximum possible energy class A according to EUROVENT with a COP of 3.22, and operating limits for ambient temperatures from -15ºC to +50ºC. Also, they are equipped with aluminum elements with epoxy paint for resistance to particularly harsh environmental conditions and a multi-function C-TOUCH color touch screen.
