Unit Description
The evaporative cooler is a completely self-contained, portable unit
capable of delivering cooled air at 6.8m/s with a temperature drop of up to
16°C. The unit is composed of:
* Level-controlled water supply system
* Cooling pad assembly
* Motor-driven fan
* Frame and housing
The housing is made of high impact poly and holds approximately 200L
water at normal operating level.
A float-operated valve automatically controls the water level when the unit
is connected to a constant water supply.
The bottom rests on, and is fixed to, a rugged steel support frame. Four
casters (2 locking, 2 regular) are attached to the underside of the steel
frame.
A pump draws water from the bottom and discharges it through the vinyl
hose to the PVC pipes located above the cooling pads. The PVC pipes
distribute water onto the top of the cooling pads saturating them. Excess
water drips back into the bottom sump of the cooling unit.
The cellulose cooling pads rest within the support channels and are held
in place by the tray and pad support plate.
The fan draws ambient air through the cooling pads where it picks up
Moisture and cools by evaporation. The fan blade then discharges the
cooled air.
