The EP Gear motors for Greenhouse PolyGearbox (RPG) is a concise and light-weight reduction gearbox with an integrated limit switch system that’s suitable for assembly of a locally available electric motor. The PolyGearbox can be used in manually-managed or climate-controlled ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is certainly rainproof and windproof. The PolyGearbox has a high protection class (IP65) and can be utilized within an ambient temperature of 0-60 °C.
The low-noise PolyGearbox has a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel transmitting ensures that the drive shaft is usually locked when the decrease gearbox is not running. The completely sealed reduction gearbox has an growth chamber with a diaphragm to keep the gear essential oil at a minimal pressure under all situations, even at high temperatures. Thanks to the use of an expansion chamber, the PolyGearbox could be installed in any position. There are no restrictions, because there is no need for a bleed connect. The 
sealed reduction gearbox keeps the gear oil of the PolyGearbox in ideal condition because of its entire operating life time. The PolyGearbox is suitable for discontinuous use, operating class s3-30%, with a maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox has an FT85 engine assembly flange, on to which a suitable IEC standard electric motor can certainly 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 within an integrated chamber and is usually enclosed by an impact-resistant plastic-type material cover. The limit change system is accessible and simple 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.
