This series of condenserless unit satisfies the cooling and heating requirements of commercial and industrial plants of medium size.
All the units are suitable for indoor installation and can be applied to fan coil plants and radiant floor plants.
The refrigerant circuit is equipped with 2 scroll compressors, mounted on rubber vibration-damper supports, plant side heat exchanger brazed plate-type in stainless steel (AISI 316), complete with thermal insulation shell and differential pressure switch, thermostatic expansion valve or electronic expansion valve (as option), dehydrator filter, solenoid valve to shut-off the liquid line, shut-off ball valves on the discharge and liquid lines, refrigerant circuit protected by refrigerant safety valve, low and high pressure switches, electrical panel for power and control complete with main breaker power supply with door lock function microprocessor controller with keyboard-display, and phase sequence controller (standard).
The units can be chosen in Basic setting up (AB) (unit without closing panels), Low noise setting up (AS), featuring closing panels coated with acoustic material, Extra Low noise setting up (AX) featuring closing panels coated with superior acoustic material and soundproofing jackets on the compressors.
The units are suitable to be combined with remote condensers cooled by air (coil and fans) or remote condensers cooled by water (plates or shel and tube heat exchanger).
The electronic controller can manage the numerous ways used on the market for the head pressure control for condensation by air and for condensation by water.
A wide range of options and accessories completes the commercial offer.
All the units are carefully built in compliance with the current regulations and individually tested.
The units are supplied with charge of NITROGEN in order to avoid the entrance of air inside the refrigerant circuit.
