Main features
Housing
Base made of painted galvanised steel; panels made of galvanised
steel externally coated with plastic (PVC) film and mounted on aluminium
profiles to ensure total weathering resistance. Panels are
internally lined to reduce the noise level (LN Accessories only).
Compressor
Reciprocating SEMIHERMETIC type, fixed on vibration isolation
mountings; complete with oil pump, crankcase electrical heater,
electronic protection, intercepting valves on suction and discharge
(mod. 015-20 HP); flexible joints on suction and discharge.
Fan
Centrifugal type with two suctions, coupled to the three phases
motor by V-belt and pulley. The fans have forward curved blades in
order to get the best performances in terms of efficiency and noise
level.
Air heat exchanger
Finned coil made with copper pipes and aluminium fins offering a
high exchange surface area.
Water heat exchanger
Shell and tube type, thermally insulated by vapour-proof closed cell.
Electrical board
Switchboard to standards IEC 204-1/EN60204-1, complete with contactor
and protection for compressor and fans. Main isolator and
door interlock safety device.
Control
The microprocessor controls the unit capacity by timing the compressors
and checks the operating alarms with the possibility to
connect to BMS.
Refrigerant circuit
Filter dryer, moisture-liquid sight glass, solenoid valve, intercepting
valve on the liquid line, thermostatic expansion valve with external
equaliser, HP and LP pressure switches.
Accessories
Spring vibration isolation.
Vibration isolation mountings.
