Dimplex air curtains provide welcome entrance to service stations
Dimplex CAB air curtains have been retrofitted at 10 Extra MSA Services site to overcome the problem of cold draughts from automatic doorways that operate many times a day.
Dimplex air curtains installed at 10 motorway service areas run by Extra MSA Services tackle the problems of noise, pollution, dust and cold draughts. Each site normally sees at least 3000 people passing though each day, and the installation of Dimplex CAB air curtains was specified by DC Electrical of Lincoln, which managed the electrical refurbishment of the sites. Some of the sites presented particular challenges. For example, the Chesterfield services area on the M1 has an unusual layout which means there are always at least two doors open during service hours — creating a through draught and a high rate of heat loss. Steve Crawford, services manager at Extra MSA Services, says, ‘Even with the large volumes of air circulated in these service areas, all the units really need is a service and clean once a year. ‘We installed the first units last Autumn at Chesterfield services on the M1, and they worked well over the winter using heated air. In recent months, we’ve been using them on the unheated air setting, and they’ve proved just as efficient. Although its a retrofit, you really can’t tell they haven’t been there since day one.’ CAB units are available in lengths of 1 and 12 m and can be fitted in pairs to cover doorways up to 3 m wide, with a total heat output of 27 kW.
