HCA air curtains reducing heating costs in a DIY store
Controls
All HCA air curtains are supplied with a control box for remote mounting.
When required, a thermostat can be connected to the control box. The thermostat will control the heat output while the fan runs continuously
How it Works
HCA high capacity air curtains are mounted above doorways and are designed to provide an invisible barrier between indoor and outdoor environments. The HCA range is well suited to stores with an open door policy. By creating this barrier, the HCA air curtain will help reduce heating costs in winter and air conditioning costs in summer, without impeding foot traffic. The HCA will also minimise the ingress of pollutants and insects
In cooler conditions, the ‘chill factor’ associated with a high velocity air stream can be uncomfortable. The HCA air curtains are therefore fitted with electric heating elements which warm the airstream thereby offsetting the ‘chill factor’ and contributing to a building’s heating requirement.

HCA air curtain suspended from drop rods
An HCA air curtain is designed for installation above doorways in commercial and industrial premises providing an invisible but effective barrier between internal and external environments. When the correct air curtain is selected benefits will include the reduction of heating costs (winter), reduction in air conditioning costs (summer) as well as minimising the ingress of insects.
HCA air curtains are effective at mounting heights between 2.5m and 4m. Ideally the selected air curtain should be longer than the width of the door. Use the following table as a guide.
Model Number |
Maximum Door Width |
HCA-09 |
1.0m |
HCA-13 |
1.5m |
HCA-18 |
2.0m |
Important Note: For an HCA air curtain to provide an effective air barrier, a high air velocity is required. The resulting noise output must be considered. For this reason, we do not recommend HCA air curtains for smaller shops or where people are working in close proximity to the entrance.
