“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.”

“The Rotowind air curtain for revolving doors was installed by M&E Contractor, HE Simm, at the Hope University in Liverpool. The air curtain is helping to maintain internal temperatures, keeping students and staff warm at the Registry Building at the Hope Park Campus.”

“Rotowind air curtain was selected to eliminate draughts in the lobby of the ME Hotel in The Strand, London. The stylish ME Hotel needed an air curtain solution that provided protection from draughts and was aesthetically in keeping with the minimalistic design of the hotel decor. This was achieved by recessing the unit into the suspended ceiling, producing a subtle design with a curve that matched the angles of the draught lobby.”

“JS Air Curtains has supplied and installed six air curtains above the doors of the University College Hospital in London. Sets of two 1.5m stainless steel air curtains and a 2.5m curved air curtain were installed above identical doorways at both the Euston Road and Beaumont Place entrances to the hospital.”

“JS Air Curtains has provided the ideal air curtain in the Rotowind G1500E, which was designed specifically for use with revolving doors. Working closely with the JS project management department, our design team subsequently fabricated bespoke plenum covers, matching the structure of the four entrance doors, to camouflage the Rotowind units.”

“We recognised the need to install an air curtain following complaints of the reception being draughty due to cold air entering the building through the external doors. The aesthetic design of the air curtain was important as it would be highly visible above our busy main entrance. As the building is electrically heated, we also needed to ensure that the installed product would not compromise its energy efficiency performance.”

“The massive cubic space of our entrance atrium was proving a challenge to heat because the revolving doors were acting as a huge fan, bringing in cold air with every turn. The Rund air curtains, positioned vertically either side of the doorway, are able to cope with this, keeping out the draught and providing sufficient heating for our reception staff. We have had no complaints of cold over the winter season and have been able to maintain a low heat output setting.”

“After a major refurbishment of this part of the building, the reception area was suffering from cold air being sucked in through the main doors. We needed an air curtain that was independently mounted, as it could not be fixed to the fascia or ceiling of the reception. Since the air curtain from JS has been installed the cold air problem has been solved.”

“Since the air curtains have been installed, we’ve noticed a considerable improvement in the internal environment. We no longer experience the draughts through our wide doorways and the temperature is much more pleasant.”
