Integrated post-heating and cooling
The integrated post-heating can be selected as either liquid-based or electrical. A low temperature, liquid-based post-heating option is also available. A cooling coil can also be integrated inside the air handling unit (liquid or DX direct evaporation). Cooling coils can also be upgraded later. Integrated cooling coils reduce condensation problems. A separate drainage of condensation water is not required.
Fast and reliable installation
The new Plug & Play solution speeds up installation and reduces the risk of errors. Factory-connected controls for valves and pump groups minimise electrical connections at the site.
