The EP PolyGearbox (RPG) is a concise and light-weight reduction gearbox with a built-in limit switch system that is ideal for assembly of a locally available electric motor. The PolyGearbox can be used in manually-controlled or climate-managed ventilation and display systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox can be rainproof and windproof. The PolyGearbox has a high protection course (IP65) and can be utilized within an ambient temperature of 0-60 °C.
The low-noise PolyGearbox includes a gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium precision housing. The self-braking worm wheel transmission ensures that the drive shaft can be locked when the decrease gearbox isn’t running. The completely sealed reduction gearbox has an expansion chamber with a diaphragm to keep carefully the gear essential oil at a minimal pressure under all situations, even at high temperatures. Thanks to the usage of an expansion chamber, the PolyGearbox could be installed in any placement. There are no limitations, since there is no dependence on a bleed plug. The sealed reduction gearbox keeps the apparatus essential oil of the PolyGearbox in ideal condition for its entire operating life time. The PolyGearbox is ideal for discontinuous use, working class s3-30%, with a maximum activation period of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 motor assembly flange, on to which the right IEC standard engine can certainly be installed (EN 50347).
The PolyGearbox includes a rotating limit switch system with operating switches and circuit Gear motors for Greenhouse breakers (NC contacts) for turning off at the end positions. The limit change system is installed within an built-in chamber and is definitely enclosed by an impact-resistant plastic material cover. The limit switch system is obtainable and easy to adjust. 
The limit switch system’s optimum switching range is usually 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The PolyGearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
