The reliable and effective RPX evaporative air coolers are proven performers for heavy duty industrial cooling.
They are often preferred by contractors where high static pressure and/or complex ductwork is experienced. These coolers have provided low cost, low energy and maintenance over many years
The cabinet is constructed of marine grade alluminium, incorporating channel section corner pillars, mounted on a heavy gauge bass frame for structural ability. Many components have been powder coated for extra corrosion protection. Cabinet fasteners are stainless steel, monel, nylon and aluminium.
Blower Wheel
The blower wheel is a double inlet, multi blade, forward curve, centrifugal type. Constructed from Galvanised steel, the wheel is statically balanced. The blower shaft is solid stainless steel and is mounted in rubber insulated, self aligning, single row ball bearings.
Water Reservoir
The water reservoir is a one piece rotational of moulding of polyethylene. providing a thick walled, corrosion free component with excellent sound deadening properties.
Fan Motors
Three phase motors are TECF tropic proof, aluminium frame, IP55 enclosures to AS 1359.
Electric control
The three phase starter assembly is prewired within the unit and incorporates a dual contactor assembly for control of the high and lowspeeds. The enclosure is hoseproof to IP55 and incorporates an isolation switch. the wall control switch supplies incorporates pump, fan and speed variation mechanisms.
Water Connection
Water supply connection is 1/2" BSP. this connects directly to a 1/2" NB standard approval ball valve. Bleed off adjustment is by an external valve located at the corner pillar.
Filter Pads
Chillcel TM with a typical saturation efficiency of 80%.
Unit Rating
Units are factory set to run, "free discharge" at the motor rated current, unless operating conditions are specified.
Motor ratings, pulley and belt sizes are nominal and may vary slightly due to manufacturing tolerances. Larger & smaller belts are available on request.
