HAHU - Horizontal Mini Air Handling Unit

The Polar Air Horizontal Mini AHU fan coil units have been specifically designed for horizontal installations and suitable for ducted air distribution. With sandwich panels to achieve low noise levels, integrated control box and panels to access components, these units represent one of the most cost-effective solutions to provide a comfortable environment for both commercial and industrial applications. Their design also reduces on-site installation time and labor costs.

Units are delivered completely assembled with motor wiring introduced into the control box to reduce on-site installation time and manpower. It contains side panels that provide easy access to fans, motors, and filters.

HAHU - Horizontal Mini Air Handling Unit Product Range

The Polar Air Horizontal Mini AHU fan coil has a range of AC and EC motor in 415V/3Ph/50Hz or EC motor in 115V-220V/60Hz units with the following capacities:

Made from frameless integrated folded steel structure, it uses a sandwich panel consisting of two walls with high-pressure PU foam inner insulation. Both walls are made of pre-coated steel 1” thickness.

Built with seamless copper tubes and headers, mechanically expanded into corrugated aluminium fin material for a permanent primary to secondary surface bond. Tested at 35 bar, with maximum operating limits at 20 bar.
