ACCESSORIES
MAIN COMPONENTS
Structure
Cooling circuit Electronic microprocessor controller
Scroll compressors Heat exchanger
Made in galvanised steel sheet
with a polyester powder coa-
ting for outdoors.
The compressor compartment
is completely sealed and may
be accessed on 3 sides thanks
to easy-to-remove panels that
greatly simplify maintenance
and/or inspection.
It can be made in three different versions with
the same power (Efficiency Pack), using mainly:
• R410A scroll compressors
• braze-welded plate exchangers
• electronic expansion valves
It allows complete management of the unit. The electronic control sy-
stem allows the setpoint to be adjusted automatically according to the
outdoor temperature in order to reduce consumption and broaden the
working temperature range. With the advanced microprocessor control
it is possible to set up LAN networks for controlling 4 units in parallel.
Scroll compressors are now
the best solution in terms of
reliability and sound power
emitted. The compressors are
supplied complete with motor
protection against overheating,
overcurrents and excessive
outlet gas temperatures.
Heat exchangers with bra-
ze-welded AISI 316 auste-
nitic stainless steel plates
and connections made of
AISI 316 L, characterised by a
reduced carbon content to
facilitate brazing.
A Power factor correction capacitors
B Soft-starter kit
C Service kit (kit of sensors for quick diagnosis)
D Clock card
E ON/OFF status of the compressors
F Remote contact for power step limits
G Configurable digital alarm card
H Pressure gauges
I Pair of Victaulic couplings for quick water IN-OUT connection
L Regulating filter kit (solenoid and tap on the liquid line)
M Outdoor temperature probe for setpoint compensation
N Normative reference other than "97/23/CE - PED"
P Unit lifting kit
