Air Curtain Controls

One of the simplest ways of saving money on any heating system is to install effective controls. Not only does an effective control strategy save you money it also ensures that a comfortable temperature is maintained within the environment. When controls are used in air curtain applications we are not only trying to maintain a temperature in order to offer comfort and climate separation we are also looking to control the fan speed. Fan speed is important so that we can ensure the correct air velocity for effective climate separation.

Too little air velocity will mean that separation between the inside and outside environments is not maintained with a possibility of loss of heat from the building. Too fast a fan speed will cause turbulence where the airstream from the air curtain collides with the floor. Again this can result in the loss of valuable heat from the building. 

The Thermoscreens Ecopower controller is supplied as standard with our complete range of heated air curtains for comercial application and is designed to prevent over heating at the building entrance and to provide measurable energy savings. Ambient air curtains are supplied with a remote control unit which allow the user to turn the air curtain on and off and to select one of three fan speeds. 

The Ecopower controller can be set in Auto mode to ensure that consistent comfort levels are maintained by using the built- in thermostat. When used in this mode the air return temperature sensor on the air curtain is disabled allowing the air curtain to be controlled via the room temperature. 

In addition, you can choose to enable weather compensation control to further enhance energy savings. In this mode the outside air temperature is used as the trigger to adjust the heat output of the air curtain. An alternative control strategy for areas where there is less foot fall may be to fit a door limit switch. 

On electrically heated units ecopower has a fan over run function to prevent nuisance tripping of the thermal cut out. In situations where you have more than one air curtain fitted in the same room Ecopower can work in a master slave mode where up to 8 air curtains can be controlled using a single remote control unit. 

The Ecopower controller can be manually controlled for either ambient, 50% or 100% heat output or can be connected to a BMS for full integration with the buildings control systems.  

  • If outdoor temperature sensor measures less than 10°C the air curtain will operate on full heat
  • If the outdoor temperature sensor measures a temperature between 10oC and 15oC the air curtain will operate on half heat.
  • If the outdoor temperature sensor measures a temperature more than 15oC the air curtain will operate in ambient mode and recirculate the ambient air in the room
