HYDRONIC
ELFOEnergy Medium
Liquid chillers and heat pumps of the ELFOEnergy Medium range, ideal
for the small-scale commercial sector, are specifically designed for outdoor
installation.
energy efficiency, especially during operation at partial loads,
High
thanks to the use of two compressors of different capacity operating on a
single cooling circuit
for systems with radiant panels or hydronic terminal units
Ideal
Hydronic
assembly supplied as standard, available with pumps with
non-standard available head and/or with double pump
tank not normally necessary, but available for applications
