EP PowerRoller roller screen drives for greenhouse

+86-13205713851 PowerRoller roller screen drives for greenhouse

EP PowerRoller (ERPR)

The EP PowerRoller is a compact, maintenance-free drive unit for operating roller screens in greenhouses. The PowerRoller has been specially designed for driving long roller screens in glass greenhouses and for rolling up the plastic film on polytunnel greenhouses. The PowerRoller can also be supplied with theEP weight compensator. This ensures that the screen rolls up and down smoothly, minimizing creases in the screen material.

 

Tried-and-tested technology

The PowerRoller was developed in-house and consists of a combination of perfectly matched worm gear and worm wheel transmissions, resulting in near-silent operation. The self-braking worm wheel transmission ensures that the double-sided output drive shafts are braked when the drive unit stops moving. The system has been tested extensively for force, functionality and durability.

The PowerRoller is equipped with a reliable limit switch system that has already proven its worth in the RW motor gearboxes. Since each roller screen is controlled independently, the screen drive units have a long lifespan. The PowerRoller is suitable for use worldwide thanks to the wide range of electric motors it can be fitted with. These electric motors vary in the number of phases, supply voltage, mains frequency and quality marks.

Even force distribution

As the PowerRoller can be installed in the middle of a roller screen, force is distributed evenly preventing extreme torsion in the roller tube. This allows you to accurately control the long roller screens that are commonly used today. It also makes the screens last longer.

The maximum roll-up height is approximately 5 metres at 43 revolutions. Various combinations of guiding systems are available for the PowerRoller. Both the bottom and top of the guiding system is available as a fixed or moveable model. At the bottom, the moveable model is designed for purlin widths of 80 mm to allow the PowerRoller to tilt freely. If the purlin width is greater than 100 mm, our fixed model can be used at the bottom.


Space-saving design

The compactEP PowerRoller combined with the guiding system requires minimal installation space, so you won´t have to modify the greenhouse structure. Even if the walls are fitted with heating pipes, only few modifications are needed. The speed of theEP PowerRoller has been adjusted to that of theEP tube motor, allowing both motors to run together perfectly.

Tightly-stretched screens with
theEP Weight Compensator (GC)

The PowerRoller can be supplied with theEP Weight Compensator. This ensures that the screen rolls up and down smoothly, minimizing creases in the screen material. It also reduces the load on the screen and the PowerRoller, extending the lifespan of both.

Thanks to the specially designed guiding system and the tilting motion of the drive unit, the roller screen can be opened or closed flawlessly. The couplings for the RPR100-4D PowerRoller ensure a seamless connection to the commonly used roller tubes with a diameter of 35 mm, 50 mm or 63 mm.

Main benefits of theEP PowerRoller

  • Compact design allows installation in any greenhouse
  • Ideal for long roller screens thanks to even force distribution
  • Suitable for various roller tube diameters: 35, 50, 60 mm
  • Minimum load on roller screen by bilateral coupling to winding tube
  • Extended screen lifespan
  • Reliable screen operation thanks to independent control of roller screens
  • Wide application range in phases, supply voltages, mains frequencies or quality marks
  • Minimal screen creasing in combination with theEP weight compensator
  • Accurate position control withEP LogicLink option
  • Near-silent operation

PowerRoller ERPR100-4 roll-up screen drivefor greenhouse

TheEP RPR100-4 PowerRoller is a maintenance-free drive unit for driving roll-up screen systems in greenhouses and livestock houses. The easy-to-install RPR100‐4 motor gearboxes are enclosed in a sealed housing with a high protection rating of IP54.

Because of its compact design and patented tilting movement, the RPR100-4 PowerRoller can be fitted with the heating ducts in the side walls of a greenhouse. With the conductor that is specifically designed for the PowerRoller and the tilting movement of the drive, a roller screen can be fully opened and closed. The RPR100-4 PowerRoller couplings ensure a seamless connection to the many suitable types of roller tubes with diameters of 35 mm, 50 mm and 63 mm.

The RPR100-4 PowerRoller has a combination of mutually tuned gearwheel and worm wheel transmissions, which results in an almost silent drive. The self-braking worm wheel transmission for the RPR100-4 ensures that the two-sided output drive shaft is locked when the drive is not running. The PowerRoller can be fitted in the centre of a roller screen system, which significantly lowers the torsion in the roller tube with larger rollup screens. Combined with weight compensation, the PowerRoller will achieve an optimal roll-up performance.

TheEP RPR100-4 PowerRoller has an integrated linear limit switch system with control and safety switches that have high switching precision. The maximum switch range for the limit switch system reaches 43 drive shaft revolutions. The PowerRoller comes supplied with a cable tree (harness) set connected to an electric motor and a limit switch system. These should be ordered separately according to the required length.

RPR100-4 PowerRoller:

  • Drive torque of 100 Nm at 50 Hz mains frequency;
  • Revolutions of 4 rpm at 50 Hz mains frequency;
  • Suitable for intermittent use, operating class S2-20%, duty cycle maximum 25 min;
  • Manual drive possible though a hexagon socket in the electric motor shaft;
  • Electric motors are supplied as standard in accordance with protection class IP55;
  • Standard suplied with a 3-phase euro-voltage motor, suitable for mains voltages of 400 V at 50Hz (type A).
