Welcome Break for JS Air Curtains
JS Air Curtains has supplied eight air curtains to the Welcome Break motorway services at Membury on the M4. The air curtains are helping to maintain internal temperatures even with the external doors in constant use.
The air curtains were installed by Russell Air Conditioning. Five 2m Windbox air curtains and three HeatScreen air curtains are positioned at the front entrance, rear entrance and on some internal doorways.
Ray Drinkwater, Facilities Manager at Membury Services, commented, “Without the air curtains the doors acted like a wind tunnel with the cold air blowing right through. The air curtains from JS were recommended by Russell Air Conditioning and have done a great job in stopping the cold air entering.”
In total the air curtains are capable of providing over 21,000m3/h of airflow to seal the doorways. As well as keeping the heat in during the winter, they can also be used with the heaters off in the summer to prevent air conditioned air from escaping.
The Windbox air curtain has a powerful output and can be used on doorways up to 3.5m high. It can be horizontally mounted above a doorway or vertically to the side. The units supplied to Welcome Break were white but the Windbox is available in any RAL colour to suit interior architecture. The air curtain can incorporate electric or low pressure hot water heating and is controlled from either a five-speed wall mounted controller, supplied with 20m of plug and play RJ45 cable, or via a BMS system.
The other model used at Welcome Break was the HeatScreen air curtain. This is an economical air curtain with a maximum output of 1,670m3/h. It can be controlled either with the panel on the front of the unit or via a handheld remote control. It is available in lengths of 90cm, 120cm and 150cm, comes with two metres of electrical lead and can be wired to a single phase power supply.
