Product Description


Characteristics


Structure
Galvanised steel construction, closed cell foam lined compressor and fan compartments, with an insulted and powder coated drain tray for complete moisture protection, the drain tray is easily removed for inspection and cleaning.
Centrifugal fan
High efficiency, double inlet centrifugal fan Protection level IP44. Low noise, low speed, big air flow and high ESP.


Refrigerant
Each unit is factory charged with refrigerant R410a, which is deemed to have zero ozone depletion potential.
Water side heat exchanger
High efficiency coaxial heat exchanger, factory insulated with flexible close cell material.


Hermetic compressor
Single phase rotary compressor is used for this type unit, with built-in thermal overload cut- out, mounted on rubber vibration dampers.
Air filter
An optional filter integrated return air spigot is available on all models.The filter is a washable polypropylene net media. Care should be taken, when locating each unit, that to enough space is provided to enable the one-piece filter to be withdrawn to its full length from either side of the unit.


Electric heater(optional)
Electric heater is optional on cooling only versions. Electric elements have spirally wound stainless steel fins to give increased area and low surface temperature. They are totally enclosed within the unit and are supplied with safety cutouts. An optional fan run-on timer for rapid heat dissipation is available.
Insulation
AMWCP are well insulated to minimise condensation and attenuate noise.
All models are equipped with wire controller with the following features
•7 days programmable timer
•Auto random restart
•Error self diagnostic


Electric panel
Consists of:
Compressor contactor
Compressor protection breaker
Microprocessor with function display
Safety protection
High pressure switch
Low pressure switch
Discharge temperature protection
Anti freezing protection
