ELFOEnergy Large²
HYDRONIC
ELFOEnergy Large2 water chillers and heat pumps provide the highest
seasonal efficiency. They’re designed to be installed outdoor and feature uneven
scroll compressors mounted in the same circuit, electronic expansion valves
and high efficiency plate type evaporators.
ELFOEnergy Large2 shows an unmatched seasonal efficiency ESEER and is
available in two versions: EXCELLENCE and PREMIUM. The standard version
EXCELLENCE offers the highest efficiency both at full and at part load. Also the
PREMIUM version offers high efficiency at part load but favour also the compact
dimensions being therefore extremely competitive.
Thanks to its features, ELFOEnergy Large2 offers:
self-adaptability in different load conditions, thanks to the availability
of several capacity steps and the adjustment logic developed for maximum
efficiency and minimum wear
very high overall reliability, thanks to the consolidated construction
choices and the use of industrially-made products
lower sound emissions, achieved thanks to the optimal sizing of the
exchange surfaces and the use of high efficiency fans with “winglets”
quick and easy installation thanks to the quick connections with the main
circuit, electrical wiring enablement and complete functional testing before
delivery. The units can also be supplied with pump assemblies, partial heat
recovery and inertial storage tank already installed on board, bringing
together all the system’s main components in a single solution.
