ELFOEnergy Duct Medium
The chillers and heat pumps of WSA-XEE and WSN-XEE series are indoor units
with ducted condensation.
Thanks to his special design ELFOEnergy Duct Medium main features are:
Versatility: different combinations of inlet and outlet plug fans enable to
connect easily the unit to the air ducts and to have high available head;
High energy efficiency: ELFOEnergy Duct Medium besides being in
Eurovent efficiency class A at full load grants high seasonal power efficiency
thanks to the innovative cooling circuit optimized for partial load operation
and the DST (Dynamic Supply Temperature) return control logic;
Easy installation: the units are very compact and are supplied with high
efficiency pumps on board; therefore the available space for other purposes
is increased and the installations costs are reduced.
