Cold store air curtains cut energy costs

Each time a cold store door is opened and in use, warm air from outside the doorway combines with the cold air inside the cold store causing energy loss.  

Temperature recordings can show an increase of between 4°C and 10°C every time a cold store door is opened. This can be improved to 1°C with an air curtain, which results in reducing heat loss by up to 90%.

As the air curtain keeps the chilled air inside the cold store, the load on refrigeration equipment is reduced along with the associated energy consumption and carbon footprint.

An efficient and correctly installed air curtain in cold stores will provide a quick return on investment with savings made on energy bills.

“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.”
