The EP PolyGearbox (RPG) is a concise and lightweight reduction gearbox with a limit switch system that’s ideal for assembly of a locally available electric motor. The PolyGearbox can be used in manually-managed or climate-controlled ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is usually rainproof and windproof. The PolyGearbox includes a high protection course (IP65) and can be utilized in an ambient temperature of 0-60 °C.
The low-noise PolyGearbox has a gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium Gear motors for Greenhouse precision housing. The self-braking worm wheel transmission means that the drive shaft is locked when the decrease gearbox isn’t running. The fully sealed reduction gearbox has an expansion chamber with a diaphragm to keep carefully the gear essential oil at a minimal pressure under all situations, even at high temperature ranges. Thanks to the use of an expansion chamber, the PolyGearbox could be installed in any position. There are no limitations, because there is no dependence on a bleed connect. The sealed decrease gearbox keeps the apparatus oil of the PolyGearbox in optimum condition for its entire operating life time. The PolyGearbox is ideal for discontinuous use, working class s3-30%, with a maximum activation period of 25 minutes.
The PolyGearbox reduction gearbox comes with an FT85 electric motor assembly flange, on to which the 
right IEC standard electric motor can simply 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 definitely enclosed by an impact-resistant plastic-type cover. The limit switch system is obtainable and easy to adjust. The limit change system’s optimum switching range can be 40 or 64 revolutions of the drive shaft. The cabling is connected 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.
