The EP 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 is used in manually-controlled or climate-controlled ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox has a high protection class (IP65) and can be used in an ambient temperature of 0-60 
°C.
The low-noise PolyGearbox includes a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel tranny ensures that the drive shaft is usually locked when the reduction gearbox is not running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep carefully the gear essential oil at a minimal pressure under all conditions, even at high temps. Thanks to the use of an expansion chamber, the PolyGearbox can be installed in any placement. There are no limitations, since there is no dependence on a bleed plug. The sealed decrease gearbox keeps the gear oil of the PolyGearbox in optimum condition because of its entire operating lifetime. The PolyGearbox is ideal for discontinuous use, working class s3-30%, with a maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 electric motor assembly flange, to which a suitable IEC standard electric motor can simply be installed (EN 50347).
The PolyGearbox has a rotating limit switch system with operating switches and circuit breakers (NC contacts) for turning off by the end positions. The limit change system is installed within an built-in chamber and can be enclosed by an impact-resistant Gear motors for Greenhouse plastic cover. The limit change system is obtainable and simple to adjust. The limit switch system’s maximum switching range is definitely 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.
