3. Compressors. They are the SCROLL type with orbiting coil equipped with built-in thermal protection and oil heater. The AS
unit includes: a soundproofing jacket for the compressors, an acoustic cladding around the compartment where they are hou-
sed, to reduce noise level, and reduced rotating speed of axial fans; AX unit integrates batteries with condensing surface
increased and rotating speed of axial fans further reduced. All units are equipped with two compressors connected in parallel
(1 single cooling circuit) which can operate at the same time (100% cooling power) or individually (50% of the cooling
power), thus adapting to the different thermal loads of the system supplied.
4. Frame structure made of galvanized sheet metal panels coated with polyurethane powder paint to ensure maximun pro-
tection against adverse weather conditions.
5. Evaporator made of brazed stainless steel plates (AISI 316). It is installed in a shell of heat-insulating material to prevent
the formation of condensation and heat exchanges towards the outside. Standard supply also includes antifreeze heater a dif-
ferential pressure switch on the water circuit to avoid the risk of freezing if the water flow is shut off for some reason.
6. Condensing coils, the aluminium finned pack type with shaped profile to increase the heat exchange coefficient and with
copper pipes arranged in staggered rows. A sub-cooling section is integrated into the lower part.
7. Covering panels, made of galvanized sheet metal coated with polyurethane powder paint to ensure maximun protection
against adverse weather conditions
8.One-way valves (IP unit only), allowing the coolant to pass into the appropriate exchangers, depending on the operating
cycle.
9. 4-way cycle reversal valve (IP unit only), reverses the flow direction of the coolant as the summer/winter operating mode
is changed.
