Compressor

The units come with two different compressor types:

  • Semihermetic: MC x B, Bitzer - MC x F, Frascond.
  • Scroll: MC x C, Copeland

All compressors are fitted with suction and discharge valves, charging connections, crankcase heater, oil sight glass, oil charge and vibration dampeners. 50 Hz threephase electric motors are protected by internal thermistors, in the lower power units, and by an external Kriwan module in the other models.

On request the compressors and fans can be supplied with a different voltage and frequencies.
Condenser

Condensers selected for the units are significantly oversized for their respective compressors, so highly efficient.

Coils are made of copper tubes and aluminum fins (2.1 mm pitch).

Axial fans are 230 V / 50 Hz single-phase with 4-poles (STD version) 6-poles (LN low noise versions) motor and 350-mm diameter.

Motors are protected by internal automatic reset thermal contacts.
QEM Electrical panel (optional)

Installed on the condensing unit, it includes: door main switch, thermal relay compressor and condenser fans protection fuses (OPT with automatic switches), compressor and fans contactor, compressor delayed start-up timer, protected secondary circuit by transformer, warning lights, terminal box ready for: pressure switches, fan speed regulator and Kriwan.

The electrical panel is supplied with all components completely wired (compressors, fans, pressostats,etc.)
