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 heater 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 garden window. Indeed, in the trade and industry sector commercial doors and modern 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



Saving energy and protecting the environment must surely come at a price?

Not necessarily. In the case outlined it is, we are pleased to say, the other way round. The gates will actually pay itself off surprisingly quickly and, depending on the field of application and location, savings will generally become apparent after two to three years if not before. After this time there should be a significant gain in contrast to the previous situation. Protecting the environment and saving energy can therefore make good business sense.

Energy conservation:

Door dimensions WxH: 3.5 x 3.5 m
14 °C difference between inside and outside temperature
8 km/h wind
50 cycles in 24 hours
250 days in operation
