The EP PolyGearbox (RPG) is a Gear motors for Greenhouse concise and light-weight reduction gearbox with a built-in limit switch system that is suitable for assembly of a locally available electric engine. The PolyGearbox is used in manually-controlled or climate-managed ventilation and display systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox can be 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 transmitting ensures that the drive shaft is definitely locked when the reduction gearbox is not running. The completely sealed reduction gearbox comes with an growth chamber with a diaphragm to keep the gear oil at a low pressure under all circumstances, even at high temperatures. Thanks to the use of an growth chamber, the PolyGearbox could be installed in any placement. There are no restrictions, since there is no need for a bleed plug. The sealed reduction gearbox keeps the gear essential oil of the PolyGearbox in optimal condition because of its entire operating lifetime. 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, to which a suitable IEC standard 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 change system is installed within an integrated chamber and is certainly enclosed by an impact-resistant plastic 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 connected in spring-clip connections. The PolyGearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
