Door Closer: Automatic Door Closers
While there are manual door closers, logically there would also be automatic door closers too. An automatic door closer opens the door automatically by using push buttons, motion detectors or other hi-tech apparatus. After which, it will then close itself automatically, typically employing a motion or proximity detector to determine when it is safe to close the door. This kind of door is much more stylish and trendy than the usual door closers. Yet because of the technology it employs, it comes at a price as it doesn’t usually make use of the usual springs and hydraulic dampers. This kind of door closer is usually installed in corporate buildings, malls and other formal establishments. Just a hint for all you interested buyers; the leading and most trusted manufacturers of door closers include Briton, Dorma, Geze and Samuel Heath (Europe-based).
