摘要：	Dangling strips of PVC have traditionally been used as an alternative to air curtains, and many operators still favour them. Many drivers of temperature-controlled vans and trucks dislike them, however, says Rupert Gatty, chief executive at fridge van conversion specialist CoolKit -especially if they wear glasses. "If you've got spectacles on, then you can guarantee that the strips will knock them off when you walk through them," he remarks. If you are on multi-drop work, than that can be umpteen times daily. Even if you do not wear glasses, going backwards and forwards through wet, cold, and potentially dirty PVC strips all day, every day, can be a dispiriting experience. As a consequence, drivers regularly tie them together, so they are out of the way even if the transport manager tells them not to; which means there is no barrier in place at all. Air curtains do not give rise to this sort of issue, says Gatty. "They're easy to walk through - you don't have to barge through a physical obstacle - and they are tamper proof," he comments. However they have one or two drawbacks. "They can reduce the height of the door aperture by perhaps 100mm," he says. "Furthermore, they sometimes need a bit of maintenance," he adds. "You may need to replace an electric motor occasionally. PVC strips have to be replaced from time to time, too, of course, although they are pretty hard wearing."
