The EP PolyGearbox (RPG) is a concise and light-weight reduction gearbox with a limit switch system that is suitable for assembly of a locally available electric motor. The PolyGearbox is used in manually-managed or climate-controlled ventilation and display 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 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 within an aluminium precision housing. The self-braking worm wheel transmitting means that the drive shaft is usually locked when the decrease gearbox isn’t running. The completely sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep the gear essential oil at a minimal pressure under all conditions, even at high temperature ranges. Thanks to the use of an expansion chamber, the PolyGearbox could be installed in any placement. There are no limitations, since there is no dependence on a bleed connect. The sealed reduction gearbox keeps the gear essential oil of the PolyGearbox in optimal condition for its entire operating lifetime. The PolyGearbox is ideal for discontinuous use, working course s3-30%, with a maximum activation period of 25 minutes.

The PolyGearbox reduction gearbox has an FT85 engine assembly flange, on to which the right IEC standard engine 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 change system is installed within an included chamber and is definitely enclosed by an impact-resistant plastic-type material cover. The limit switch system is accessible and simple to adjust. The limit change system’s maximum 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 Gear motors for Greenhouse feed-through.
