Constructedfrom galvanised steel, the wheel is statically balanced, The blower shaft is mounted inplumber blocks with, self aligning, single row ball bearings. RPC Coolers are fitted with aPlastic Blower Wheel.

Water Reservoir.The water reservoir is a one piece Rotational Moulding of Polyethylene, providing a thickwalled, corrosion free component with excellent sound deadening properties.

Fan Motors.RPC Models & RPA400 are 240V Single Phase, two speed PSC motor. RPA450 to 900are 415V 3 Phase TEFC tropic proof induction motor, Aluminium or Cast Iron frame, IP55enclosures to AS1359. Motor current draw can vary depending on supplier.

Electrical Control.A Three Phase DOL starter assembly is pre-wired within the unit and incorporates a dualcontactor assembly for control of high and low speeds, Current overloads are fitted toboth high and low contactors. The enclosure is hose proof to IP55. All 3 phase modelsincorporate an isolation switch. Single phase is wired directly to mains.The wall control switch supplied incorporates the Pump, Fan and High/Low mechanisms.

Water Connection.Water supply connection is 1/2" BSP, this connects directly to a 1/2" NB standardapproved ball valve.

Filter Pads.Filter pads are Chillcel® with a minimum operating saturation efficiency of 80%. Shreddedwood wool fibre is available on some models. All models incorporate Plastic Louvres (UVstabilised) to enhance the appearance of the pad and to prevent water splash.

Special Features. Bleed off adjustment is by an external valve located at thecorner pillar. A mains isolator is provided. Flexible Connectors are fitted on all downdischarge models and supplied in kit form for Side and Top Discharge Models.A Lifting Lug Kit is also available for all models and can be factory fitted.
