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 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 definitely 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 in 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 completely sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep the gear essential oil at a low pressure under all situations, even at high temperatures. Thanks to the utilization of an expansion 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 life time. 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 electric 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 can be enclosed by an impact-resistant plastic cover. The limit Gear motors for Greenhouse change system is obtainable and easy to adjust. The limit switch system’s optimum switching range is certainly 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.
