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 engine. The PolyGearbox is used in manually-controlled or climate-managed ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox includes a high protection class (IP65) and can be used 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 tranny ensures that the drive shaft is definitely 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 low pressure under all situations, even at high temperature ranges. Thanks to the usage of an expansion chamber, the PolyGearbox could be installed in any placement. There are no restrictions, since there is no dependence on a bleed connect. The sealed decrease gearbox keeps the gear oil of the PolyGearbox in ideal condition because of its entire operating life time. 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 has an FT85 electric motor assembly flange, to which a suitable IEC standard motor can easily be installed (EN 50347).
The PolyGearbox has 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 included chamber and is enclosed by an impact-resistant plastic-type cover. The limit change 
system is obtainable and easy to adjust. The limit switch system’s maximum switching range is 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.
