Automatic roller shutters use automatic belt winders.

Rademacher : 23 August, 2007  (New Product)
New belt drives make automating roller shutter opening and closure simpler and more reliable.
Automatic rolling shutters which open and close all by themselves without the daily pulling and tugging on the shutter belt - a dream for many. Adding this convenience to existing shutters is a simple matter with automatic belt winders. The previous manual belt winder is simply replaced with practical drive. More convenience in your own four walls in only minutes, with virtually no mess or installation noise. But careful consideration should be given to the decision about buying even this simplest way to automate rolling shutters: many drives do not deliver what they promise because the tensile force is too low and the motors are of low quality. You can be confident when you choose the inventor of the automatic belt winder, Rademacher, the company with tradition: Rollotron, the original which has proven itself millions of times, has been continually improved over decades and has plenty of power reserves to guarantee trouble-free operation even for old and stiff rolling shutters. Moreover, the quality product convinces users with its comfortable functions and technical innovations - such as the new radio system DuoFern used in the Rollotron for the first time.

"Our specialist dealers regularly report to us about disappointed customers who have bought low-price belt winders from a discounter or in a DIY shop which, despite the grand promises in the advertising, have nowhere near the tensile force required to move old and stiff rolling shutters," reports Jim Newby, Export Manager at the manufacturing company Rademacher. "The customer is given the impression that the size of the shutter is the only factor that must be taken into consideration when selecting a belt winder. But the age, material and belt webbing are equally important, if not more so." While rolling shutter automation with automatic belt winders really is easy, taking a mature product and speaking to the experts in the speciality shop will protect you from unpleasant surprises and the wrong purchase.

The Rollotron from Rademacher is the powerful original. The drive in the models Rollotron Pro Standard and Comfort has a tensile force of 45 kg and can easily move even older rolling shutters with an area of up to 6 m². The Standard and Comfort models as well as a Plus variant with a tensile force of 60 kg are available for even larger and heavier shutters. The simple to install drive is the ideal drive solution for large rolling shutters with an area of up to 10 m². The Rollotron is also available as a pivoting winder with a tensile force of 30 kg for surface mounting. All of the Rollotron models have an especially high-quality motor - the drive is not only especially strong, but is also robustly designed and works extremely quiet. This high-quality drive concept was recently singled out for special praise in the test magazine, HeimwerkerPraxis. The belt winder from Rademacher came out ahead of the competition as the test winner and scored an overall grade of 1.1.

Belt winders like the Rollotron are the simplest and least complicated way to achieve more comfort. Even heavy and stiff rolling shutters can be automated with the automatic belt winders in only a few minutes. The shutter belt is simply removed from the old belt winder and wound on the Rollotron. As a rule, the Rollotron fits into the previous belt box. A common 230 V power outlet is all that is needed to supply electrical current. As a rule, breaking through the plaster on the walls is just as unnecessary as expensive painting and wallpapering.

Despite the very simple installation, the Rollotron Pro is a match for more complicated solutions in terms of comfort thanks to its large display and intuitive operation: in the Comfort model, the drive offers weekly and weekend programmes and a random function which simulates your being home by varying the opening and closing times, a feature which gives burglars pause for thought. A radio-controlled clock takes care of operational precision and automatically changes to summer time and back. The ASTRO function determines the twilight time on the basis of the local postal code and closes rolling shutters just as it becomes dark. A keypad block protects the device from clever children's hands. The Standard model does not require a display, yet allows daily operating times to be programmed.
The integrated automatic sun and twilight function is practical for the coming summer. All customers need to do is add an inexpensive sunlight/twilight sensor to the Rollotron, and the rolling shutters open and close according to brightness and the amount of sunlight.

Rademacher integrates a unique radio system in the Rollotron Pro - DuoFern. DuoFern operates bi-directionally - the operator receives feedback about the successful transmission of the radio commands on the hand-held transmitter. This is ideal when rolling shutters in spots which cannot be seen are controlled using a hand-held transmitter. A high level of operating security and simple installation guarantee the routing function of the DuoFern system: every Rollotron Pro DuoFern is simultaneously a transmitter and forwards radio commands to receivers which are further away. So the transmission strength of each individual device is kept to a moderate level, yet a reliable and uncomplicated wireless control throughout the building becomes possible. The innovative master/slave function makes the use of DuoFern especially flexible. Individual DuoFern components can act as controls for additional DuoFern devices. In a DuoFern environment, subordinate groups of components with the same operating times can be created. That saves money when, for example, Rollotron Pro DuoFern Standard is controlled by the various timer programmes of a Rollotron Pro DuoFern Comfort acting as a master.

Whether the Standard or Comfort model, with or without DuoFern functionality - Rollotron is the powerful original with the high-quality motor and high tensile force. Millions of satisfied Rollotron customers can confirm this and know that, whatever the technical marvels and comfort functions, automation of rolling shutters is above all a question of tensile force.
