HIGH ENERGY EFFICIENCY
The use of several scroll compressors in parallel ensures
high performance at partial loads, with the absorbed power
decreasing in proportion to the cooling capacity demand.
The electronic thermostatic valve, available as an option,
offers further energy savings and high precision capacity
control; the microprocessor analyses signals transmitted
by the sensors in the circuit and consequently adjusts the
degree of opening of the valve, thus optimising operation in
all load conditions.
ADVANCED MICROPROCESSOR
Thanks to its processing power the 32-byte programmable
microprocessor permits energy efficiency maximization in
all load conditions and the management of up to 4 units
in master-slave mode. The microprocessor features STATUS
CONTROL design, presenting the user with a full range of
information concerning the status of the various controlled
parameters.
Remote interfaceability is assured by means of a GSM
modem and full compatibility with the most widely used
Building Management System (BMS) communication
protocols: BACnet, Lonworks, and ModBus.

MULTI-SCROLL TECHNOLOGY
Multi-scroll technology, with several compressors in parallel
on each circuit, ensures maximum performance at partial
loads by varying the cooling capacity in proportion to the
real demand. This solution also reduces the system minimum
thermal inertia value and its related energy loss. Apart
from reducing the level of absorbed power, progressive
disactivation of the compressors and fans renders Galaxy
extremely quiet, making it ideal for installation in noise-
sensitive surroundings.
Air-cooled chillers with R410A or R407C equipped
scroll compressors. Cooling capacity 480 - 1442 kW.
EASY TO INSTALL
Storage tank, single or double pumps, expansion vessel,
pressure relief valve, and pressure gauge: with Galaxy all the
main hydronic components can be installed on board.
This translates into savings in time otherwise required
to select hydraulic circuit components, plus simplified
installation procedures, leading to reduced installation times
and costs.
Galaxy is supplied, as standard, with a differential pressure
switch protecting the evaporator and with “Victaulic”
connections to help reduce vibration, noise levels and the
problems associated with thermal expansion of the pipin
