The EP PolyGearbox (RPG) is a concise and light-weight reduction gearbox with a limit switch system that is ideal for assembly of a locally available electric electric motor. The PolyGearbox is utilized 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 used in an ambient temperature of 0-60 °C.
The low-noise PolyGearbox has a Gear motors for Greenhouse gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium precision housing. The self-braking worm wheel tranny means that the drive shaft can be locked when the decrease gearbox isn’t running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep the gear oil at a minimal pressure under all circumstances, even at high temperatures. Thanks to the use of an expansion chamber, the PolyGearbox could be installed in any position. There are no limitations, since there is no dependence on a bleed connect. The sealed reduction gearbox keeps the apparatus essential oil of the PolyGearbox in optimal condition because of its entire operating lifetime. The PolyGearbox is suitable for discontinuous use, operating class s3-30%, with a maximum activation period of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 motor 
assembly flange, on to which a suitable IEC standard electric motor can simply be installed (EN 50347).
The PolyGearbox includes a rotating limit switch system with operating switches and circuit breakers (NC contacts) for turning off at the end positions. The limit change system is installed in an built-in chamber and is definitely enclosed by an impact-resistant plastic material cover. The limit change system is obtainable and simple to adjust. The limit change system’s optimum switching range can be 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The PolyGearbox comes with an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
