4. Compressors. These are the SCROLL type with orbiting coil equipped with built-in thermal protection and oil heater. As part
of the standard supply, they are positioned on rubber vibration dampers to reduce the vibrations transmitted to the base of the
unit. To lower the sound emission of silenced version AS, they are installed in a soundproofed booth made of galvanized sheet
metal coated with polyurethane powder paints and covered in soundproofing material.
5. Bearing structure made of galvanized sheet metal coated with polyurethane powder paint to ensure good protection against adver-
se weather conditions.
6. Water storage tank (accessory that must be requested when the unit is ordered) Made of adequately thick painted sheet
metal, this reduces the number of compressor start-ups and fluctuations in the temperature of the water conveyed to the users.
It is insulated with thermal barrier insulating material to prevent the formation of condensation and heat exchanges towards
the outside. In conjunction with the Pumping Module accessory, it can be supplied in 3 different configurations: Storage on the
Delivery, Storage on the Return, Storage pre-engineered for Primary and Secondary circuits. In conjunction with the Pipe Kit,
the only configuration possible is the one with Storage on the Delivery.
The water drain is installed under the tank as part of the standard supply. The water is turned on and off by a cock that allows
the unit to be drained.
7. Air vent. The automatic type, turned on and off by a cock and positioned on the highest part of the tank.
8.Water safety valve, on the rear part of the tank. It acts whenever faulty service leads to an operating pressure in the plumbing
system that exceeds the valve opening value.
9.Antifreeze heater connection. 1 1/4 female threaded connection pre-engineered for installation of the tank s antifreeze hea-
ter.
10. Evaporator, plate type made of braze-welded stainless steel (AISI 316), double chilling circuit and alternate water/refrige-
rant circuits. It is installed within a shell of thermal barrier insulating material to prevent the formation of condensation and heat
exchanges towards the outside. Standard supply also includes a differential pressure switch on the water supply circuit to avoid
the risk of freezing if the water flow is shut off for some reason.
11. Condensing coils, the aluminium finned pack type with shaped profile to increase the heat exchange coefficient and with
copper pipes arranged in staggered rows.
12. Covering panels, made of galvanized sheet metal coated with polyurethane powder paints to ensure the utmost ability to
withstand adverse weather conditions.
