“We were using electric doors but wanted to have better access and visibility for the forklifts. We also had heat spots near the door and were getting about 8°C with the door open. However, without the door and with the air curtains installed we are now maintaining 2°C, even right next to the doorway in the summer.

Since seeing how effective the air curtains are at sealing the entrance, I’ve ordered two more for a chill store at our Passion Food Café facility in Portsmouth.”

“We trialed the air curtain for two weeks as we were concerned that the down-draught would damage the flowers and that it wouldn't create a seal across the door. However, the down-draught had no effect on the flowers and it sealed up the fridge and ambient working area very well – a lot better than I expected it to.

It’s difficult to quantify a financial benefit from any energy savings at this time. However, based on maintenance for the existing fast acting roller door alone, the payback period will be between 8 and 17 months.”
