Condenser Coils
Large surface area coils ideally positioned to optimise airflow and heat transfer,
manufactured from micro channel coil.
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 -30°C.
Head pressure can be set, monitored and values viewed at the microprocessor
display.
Corrosion Resistant Coated Coils
In atmospheres where high corrosion is anticipated a corrosion resistant epoxy
coating is applied to the aluminium fins.
Evaporator
Shell and Tube Heat Exchanger(s) will allow optimum heat transfer between
media. Each heat exchanger shall be insulated with closed cell polyurethane
foam to Class 1 fire rating.
A immersion heater is fitted to the single evaporator and will protect against
freeze up in ambient temperatures as low as -30°C. This is however subject to
the Freeze protection policy.
Internal water pipework is trace heated.
Connections for External Trace Heating (230V/1PH / 50Hz / 500W) available.
