GENERAL FEATURES
3. Compressors.
They are the SCROLL type with orbiting coil equipped with built-in thermal protection and oil heater (accessory for
IR, as standard for IP). The AS unit includes: a soundproofing jacket for the compressors, to reduce noise level. 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,
supporting structure and lateral panels are made of galvanized and painted sheet-steel (colour RAL 7035) to guarantee
good resistance to the weather. Accessibility to internal parts is possible removing the frontal panel, for other manteinances also the
lateral panel can be removed.
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 differential
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.
