Refrigeration Components
Condenser Large surface area coils ideally positioned to optimise airflow and heat transfer,
manufactured from micro channel coil or Copper tube with aluminium fins
For DCC models the condenser is manufactured from Copper tube with aluminium
fins whilst the DCF variant has aluminium micro channel.
Head Pressure Control Electronic head pressure controllers are fitted which modulate the fan speed to
maintain a constant condensing pressure, allowing the system to operate
satisfactorily in ambient temperatures as low as -20°C.
Head pressure can be set, monitored and values viewed at the microprocessor
display.
Compressor Staging The sequence of the compressor staging has been engineered to
optimise the units ESEER performance.
Compressor Scroll compressors comprising:

Internal motor protection

Internal pressure relief

Non return valve

External discharge temperature protection

Oil sight glass
Each Tandem / Trio set has an oil equalisation line.
The compressors are mounted to the rigid galvanised heavy duty sub-frame with
the use of vibration reducing isolation.
