General Description
7.2 General specifications
The CLS/CLH units are supplied complete and pro-
vided with all connecting pipes for the refrigerant
and internal wiring.
The refrigeration circuit of each CLS/CLH unit under-
goes a pressure test, is drained, vacuumised, dehy-
drated and filled with refrigerant, and includes the
necessary oil. Once assembled, each unit is subject-
ed to a complete final testing and the correct opera-
tion of all refrigeration circuits is checked.
The base and the frame of each unit are made of
very thick galvanised sheet, and are secured by
screw and tropicalised steel bolts. All panels can be
disassembled for easy access to internal compo-
nents.
All galvanised steel parts are painted with white
polyester resin (RAL 9001), to ensure the resistance
of the unit to corrosion and weather agents over
time.
7.3 Compressors
The CLS/CLH units are provided with hermetic scroll
compressors, with built-in motor protection.
7 GENERAL DESCRIPTION
7.1 Introduction
The CLS/CLH units are water chillers/air - water heat
pumps with hermetic scroll compressors with double
refrigeration circuit.
These units are fit for cooling and heating the water
necessary for each air-conditioning application and

CLH EH Heat pump unit, with 1 or 2 pumps + tank with additional resistors
Compressors are mounted on shock absorbers to re-
duce vibrations. Motors are of direct start-up type,
cooled by the sucked refrigerant gas.
Thermistors protect the windings from any overtem-
peratures and the electronic control checks that the
delivery temperature is within the permissible range.
The capacity control, as well as the control of the de-
livered cooling capacity, are always ensured by the
electronic control.
7.4 Refrigeration circuits
Each unit has two complete refrigeration circuits, one
per each compressor. Each refrigeration circuit in-
cludes: a service valve to fill the unit with refrigerant,
shut-off valves, thermostatic expansion valve, dehy-
drating filter, sight glass with humidity indicator, a
differential pressure switch for the water. Condens-
ing unit CLC deriving from CLS and are without
evaporator. This units have check valve on suction
line and liquid line, it allows to collect with remote
evaporators. Furthermore, each circuit is equipped
with safety devices in accordance with PED
97/23/EC: high and low pressure switches, safety
valves providing protection in case of fire or malfunc-
tion of compressors.
other types of fluids, such as, for example, glycoled
water, that can be used in industrial processes.
The units are fit for outdoor installation on the roof of
a building, or at ground level.
The series includes the following variances:
For each CLS version is available the eqivalent con-
densing unit: CLC.
