General Description
INTRODUCTION This range of air cooled condensing units covers the range 40 kW to 161 kW in seven
model sizes and has been custom designed to maximise performance whilst
minimising footprint, profile and noise.
The range is ideal for application on any split system where the benefits of a range of
units employing two independent refrigeration circuits can be fully realised.
Airedale condensing units are run, wired, function tested and leave the factory with a
holding charge of ozone friendly nitrogen.
These units are purpose designed for outdoor applications and are fully
weatherproofed for adverse climatic conditions.
CONSTRUCTION CUS 15-30D
The base utilises a lock bolted channel sub frame, the upper section being of a
pentapost type construction. A totally enclosed weatherproof compressor
compartment features full access to all refrigeration components. All items are
fabricated from galvanised steel and coated with an epoxy baked powder paint for a
durable weatherproof finish.
CUS 40-60D
The cabinet is fabricated from galvanised steel coated with an epoxy baked powder
paint, giving a durable weatherproof finish. A fully weatherproofed electrical panel is
situated at one end of the unit.
Standard unit paint colour is Charcoal Grey (RAL 7022).
CONDENSER Large surface area condenser coil(s) manufactured from refrigeration quality copper
tubes, with mechanically bonded aluminium fins.
FAN A 610mm diameter axial flow fan assembly with low noise paddle type blades. The
unique external rotor motor design allows the use of a low power output single phase
speed controllable motor to power the fan. The motor has inbuilt thermal overload
protection, and the assembly is supplied complete with a finger guard for protection.
