Main features<br />
Housing<br />
Frame made of painted galvanised steel heavy profiles to ensure<br />
total mechanical and corrosion resistance.<br />
Compressor<br />
Reciprocating SEMIHERMETIC type, fixed on vibration isolation<br />
mountings; <strong>com</strong>plete with oil pump, crankcase electrical heater,<br />
electronic protection, intercepting valves on suction and discharge<br />
(mod. 015-20 HP); flexible joints on suction and discharge.<br />
Water heat exchanger<br />
Shell and tube type, shell made of thick steel ; exchanger thermally<br />
insulated by vapour-proof closed cell (evaporator for cooling only<br />
unit; evaporator and condenser for heat pump unit).<br />
Electrical board<br />
Switchboard to standards IEC 204-1/EN60204-1, <strong>com</strong>plete with<br />
contactor and protection for <strong>com</strong>pressor. Main isolator and door<br />
interlock safety device.<br />
Control<br />
The microprocessor controls the unit capacity by timing the <strong>com</strong>pressors<br />
and checks the operating alarms with the possibility to<br />
connect to BMS.<br />
