The EP PolyGearbox (RPG) is a compact and light-weight reduction gearbox with a limit switch system that’s ideal for assembly of a locally available electric motor. The PolyGearbox is utilized in manually-managed or climate-managed ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox can be rainproof and windproof. The PolyGearbox has 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 tranny Gear motors for Greenhouse ensures that the drive shaft is usually locked when the reduction gearbox is not running. The fully sealed reduction gearbox has an growth chamber with a diaphragm to keep the gear essential oil at a minimal pressure under all situations, even at high temperatures. Thanks to the use of an expansion chamber, the PolyGearbox can be installed in any placement. There are no limitations, since there is no need for a bleed plug. The sealed reduction gearbox keeps the apparatus oil of the PolyGearbox in optimal condition for its entire operating life time. The PolyGearbox is suitable for discontinuous use, operating class s3-30%, with a maximum activation period of 25 minutes.

The PolyGearbox reduction gearbox has an FT85 electric motor assembly flange, to which a suitable IEC standard electric 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 in an integrated chamber and is 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 is definitely 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The PolyGearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
