| High Speed Rolling doors  Energy prices are rocketing and the climate scientists are sounding the alarm. Everyone is talking about CO2 emissions and saving energy. However, what is a pain in the wallet for the consumer can translate into an acute price jump for the manufacturing industry and an accompanying decrease in competitive ability. There are many ways of tackling the problem, such as converting to energy-saving production methods, using more efficient machinery, installing new heating systems or insulating buildings. Sometimes, however, the solution is much more obvious and is therefore totally disregarded. The energy - and in other words the money - is literally flying out of the window. Indeed, in the trade and industry sector doors and gates often need to be opened hundreds of times a day. The doors are then left open and may need to remain open for some time or they are only closed again after a certain amount of time. During this time warm air is pouring out of the heated part of the building - making it necessary to use more energy to replace the lost heat. While the amounts are small in and of themselves, they have a huge knock-on effect and, given the number of times the doors are opened, add up to an appreciable sum. The greater the difference between the outside and inside temperature and the more frequently the doors have to be opened, the greater the increase in consumption and therefore in costs.In developing its High Speed Rolling door, Albany Door Systems has gone a long way to solving this problem. High Speed Rolling doors have been developed in response to this very problem of frequent opening and closing. Example: RapidRoll 3000: RR 3000 opens 84% faster RR 3000 closes 60% faster than a standard door of the same size. Basic assumption: RR3000 V = 2.3 m/s Standard door V = typ. 0.2 m/s write your comments about the article :: © 2008 Construction News :: home page |
