The units are shipped with a sealed charge of nitrogen.
(1) data referred to the following conditions :
internal exchanger water = 12/7°C
condensing temperature = 50°C
(2) According to EUROVENT the Total Power Input does not consider the pump share,
required to overcome the pressure drop for the solution circulation inside the exchangers.
(3) Continuous regulation power control (Stepless)
(4) Fittings with flexible joint and solder pipe connection
