The EP PolyGearbox (RPG) is a concise and lightweight reduction gearbox with a limit switch system that is suitable for assembly of a locally available electric motor. The PolyGearbox can be used in manually-controlled or climate-controlled ventilation and display systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox includes a high protection course 
(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 tranny means that the drive shaft is usually locked when the decrease gearbox isn’t running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep carefully the gear oil at a minimal pressure under all conditions, even at high temperatures. Thanks to the use of an growth chamber, the PolyGearbox can be installed in any placement. There are no limitations, because there is no need for a bleed connect. The sealed reduction gearbox keeps the apparatus essential oil of the PolyGearbox in optimal condition for its entire operating lifetime. The PolyGearbox is ideal for discontinuous use, operating course s3-30%, with a Gear motors for Greenhouse maximum activation time of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 motor assembly flange, to which the right IEC standard electric motor can easily 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 switch system is installed in an built-in chamber and is usually enclosed by an impact-resistant plastic material cover. The limit change system is accessible and easy to adjust. The limit switch system’s maximum switching range is certainly 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.
