The EP PolyGearbox (RPG) is a compact and light-weight reduction gearbox with an integrated limit switch system that is suitable for assembly of a locally available 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 is usually 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 gearwheel transmission and a worm wheel transmission, which are integrated Gear motors for Greenhouse within an aluminium precision housing. The self-braking worm wheel transmission ensures that the drive shaft is locked when the decrease gearbox is not running. The completely sealed reduction gearbox has an expansion chamber with a diaphragm to keep carefully the gear oil at a minimal pressure under all circumstances, even at high temps. Thanks to the use of an expansion chamber, the PolyGearbox can be installed in any placement. There are no restrictions, since there is no need for a bleed connect. The sealed decrease gearbox keeps the apparatus oil of the PolyGearbox in optimal condition for its entire operating life time. The PolyGearbox is ideal for discontinuous use, operating class s3-30%, with a maximum activation time of 25 minutes.

The PolyGearbox reduction gearbox comes with an FT85 electric motor assembly flange, on to which the right IEC standard 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 built-in chamber and can be enclosed by an impact-resistant plastic material cover. The limit switch system is accessible 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 comes with an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
