Polaris • Unit heater

Unit heaters
Horizontal or vertical discharge

Datasheet

The Polaris air conditioners for vertical discharge offer a practical and economical

solution for space heating and cooling with hot water supply (17 - 107 kW) or chilled

water supply (2 - 20 kW)

Range

DRA (Radial louvre) - It is the model most commonly used: made up of eight separately adjustable large louvre, so shaped as to be able to cover the whole of the outlet area and therefore adaptable for minimum to maximum heights. This diffuser allows the air to be directed more easily to the areas where it is required the most, or conversely, if you do not require air to one particular corner you can close down one, two or three vanes and restrict the distribution
DA (Four cone diffuser) - It is designed to distribute the air in large open areas at a reasonably low level. Its other particular advantage is its low noise level operation and the aesthetic appearance. Ideal for restaurants, schools, hospitals, theatres etc

Material

Casing

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

Heat exchanger

The heat exchanger is manufactured from the highest quality copper tube.

The fins are pressed from aluminium sheet, bonded onto the tubes facilitating the

maximum transfer contact available

Helicoidal fan

The helicoidal fan is statically and dynamically balanced, the rational high-capacity

profile provides maximum air volume with a minimum power consumption

Electric motor

The motor fitted is hermetically sealed and therefore maintenance free. It is supplied as standard for a three phase 230/400 V 50 Hz

two speed 6/8 poles

Options

IP 55 motor protection
Flanged connections
Steam execution
