What's the benefit?

• Doors can remain open
  By creating an 'invisible door' using the fast moving airstream people can pass easily from area to area without doors hindering progress.
• Prevents heated or cooled air escaping
  An effective air curtain separates two zones allowing different temperatures to be maintained.
• Reduces draughts and discomfort
  Comfort levels for staff, customers and visitors close to the doorway are increased by air curtains reducing draughts through frequently opening doorways.
• Energy saving
  Costs of running heating and air conditioning systems can be reduced with air curtains as they help to seal the building from the environment, making the building more energy efficient.
• Reduced ingress of insects and pollutants
  Insects, pollens and other airborne pollutants can be minimised with air curtains as they block much of these from entering the building.

How do they work?

1. Air curtains work by separating two different temperature zones with an invisible curtain of air. They provide a fast moving air stream to block air movement through the door whilst allowing the door to remain open.
2. Placing an air curtain above or to the side of the entrance covering the full door width maximises performance by stopping heated air escaping in winter, or cooled air escaping in summertime.
3. Positioning the air curtain too far from the entrance compromises performance with air leaking around the airstream.
4. Where extractor units are used within the building, ventilation should also be provided to equalise pressure differences for maximum air curtain effectiveness.
5. By retaining the cooled air within a cold storage room, an air curtain dramatically reduces waste energy and gives unhindered access from area to area. With no doors or curtains to reduce visibility, user safety is improved for those moving around the building.

The range

Energy Saving Air Curtains

Lower Energy Bills
Significant reductions in HVAC running costs for a given premises
can be realised with a correctly installed air curtain.

Energy Saving with Dimplex Air Curtains

De-rated Installation Mode

For installations where a lower electrical input is desired, Dimplex air curtains can be permanently modified at installation to consume up to 50% less energy for reduced running cost.

Interlocked Installation Mode

By connecting the Dimplex air curtain to A/C plant or a heating system, up to 50% reduction in air curtain running costs can be realised as the air curtain modifies output dependent on heating or air conditioning mode.

Interlocked and De-rated Installation Mode

Where a lower electrical input power is desired and appropriate, and the Dimplex air curtain can be connected to the heating or air conditioning system, then up to 97% of air curtain running cost can be recouped.

Auto Door Sensor Mode

Save hundreds of pounds every year by fitting an inexpensive magnetic door sensor to the pre-programmed Dimplex control system. As the doors open and close, the air curtain optimises output accordingly.

Passive Infra-Red Sensor Mode

Save hundreds of pounds every year by using a PIR passive sensor with the Dimplex control system. As the PIR senses people movement, the Dimplex standard control system optimises output to match.

Thermostat Regulation Mode

No need for PWM systems that cost the earth. Thermostatic regulation fitted as standard** is the most cost effective way to save energy. Switching heat in and out as conditions dictate without limiting performance.
