Electric air heater POLARIS

hot waterceiling-mounted

The Polaris circular unit heaters, for ceiling installation only, are especially suitable for high rooms, even if the optimum ratio between the air flow-rate and the heat output make them suitable for any manufacturing environment. The large heat exchange coil and the fan downstream of the coil ensure optimum mixing of the air in the environment, meaning less stratification of the hot air than with traditional unit heaters. When supplied with cold water they can also be used in the summer months, thus allowing cooling at very reasonable costs. The Polaris unit heaters are made in 10 sizes, all fitted with very silent two speeds motors motors, heat outputs from 17 to 107 kW and cooling capacities from 2 to 20 kW. The casing is made of spun steel on both top and bottom sections which is designed to give greater strength and quieter operation. The casing is then finished with an epoxy, polyester powder coating of light grey, RAL 9002. • The circular coil is constructed of copper tubes with aluminium fins. • The helicoidal fan is statically and dynamically balanced, the rational high-capacity profile provides maximum air volume with a minimum power consumption. • Standard motors are three phase 400 V, closed frame, flange mounted, pre-greased bearings, protection IP 44. Available with double speed double wiring at 6/8 pole (900-700 r.p.m.). Made of eight separately adjustable large louvres, shaped so as to be able to cover the whole outlet area and therefore adaptable for minimum to maximum heights.
