Roof Top Air Conditioners Manufacturers

Roof Top air conditioners is a self-contained, air-conditioning unit that comprises mixing box, filter, direct-expansion cooler coil, air-cooled condensing unit, direct-fired air heater battery and supply fan with motor, drive and switch gear. This unit is weather-proofed, prewired and factory tested. It only requires electrical connections and a gas or oil feed, after erection on the roof, to operate. Such units are available in a range of capacities from 5 to 100 kW of refrigeration and from 17 to 150kW of heating. The filters provided as standard are generally washable polyurethane foam or oil-impregnated glass fibre, but electrical filters can also be obtained. The advantage of roof-top units are that they are simple and cheap, no boiler plant is needed, duct distribution systems can be reduced to a minimum, multiple units can be used to provide multiple zone control and they are ideal for single-storey commercial buildings.
