The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with a built-in limit switch system that is suitable for assembly of a locally available Gear motors for Greenhouse electric electric motor. The PolyGearbox is used in manually-controlled or climate-managed ventilation and screen 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 utilized in 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 transmitting means that the drive shaft is usually locked when the decrease gearbox is not running. The fully sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep carefully the gear essential oil at a low pressure under all situations, even at high temperatures. Thanks to the use of an growth chamber, the PolyGearbox can be installed in any position. There are no limitations, because there is no need for a bleed plug. The sealed reduction gearbox keeps the apparatus essential oil of the PolyGearbox in optimum condition because of its entire operating lifetime. The PolyGearbox is suitable for discontinuous use, working course s3-30%, with a maximum activation time of 25 minutes.

The PolyGearbox reduction gearbox comes with an FT85 engine assembly flange, to which the right IEC standard motor can certainly 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 switch system is installed in an included chamber and is certainly enclosed by an impact-resistant plastic material cover. The limit change system is obtainable and easy to adjust. The limit switch system’s optimum 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.
