THE SERIES
Galletti has developed this product for the production of hot water for heating
systems - especially in demand for independent homes - with the aim of
reducing primary energy consumption and operating costs compared to
conventional gas or electric systems, thanks to a high level of efficiency:
average COP 3.33 (Eurovent Energy Efficiency Class A)
average EER 3.23 (Eurovent Energy Efficiency Class A)
OPTIMISED FOR OPERATION IN THE HEATING MODE
-
Plate heat exchanger with reverse-flow operation in the heating mode
(+7% increase in efficiency).
-
Finned coil with wide fin spacing
-
Desuperheater in the pipes at the base of the finned block heat exchanger.
-
Heating cable on the base in the internal part of the finned coil.
-
Facilitated condensate drainage
YEAR-ROUND OPERATION
MXE heat pumps have been designed to work in the heating mode with
outdoor air temperatures ranging from -15°C to + 30°C, producing hot water
at temperatures of up to 55°C, and in the cooling mode with air temperatures
ranging from -10 to +45°C.
The electronic expansion valve and
condensation control (under pressure)
contribute to increasing the working range.

SMART DEFROST SYSTEM
The exclusive defrost system (optional feature available with the advanced
controller) can correctly identify an impairment of performance in the outdoor
exchanger due to the formation of ice and minimise the process time in
relation to normal operation of the unit.
SELF-ADAPTIVE
The electronic control system allows the setpoint to be adjusted automatically
according to the outdoor temperature in order to reduce consumption and
broaden the working temperature range.
The unit can also function in systems with a low water content, even
without the use of a storage reservoir, thanks to the automatic adjustment
which limits the number of compressor starts and thus extends the life of
the compressors themselves.
