The EP PolyGearbox (RPG) is a concise and light-weight reduction gearbox with a limit switch system that is ideal for assembly of a locally available electric motor. The PolyGearbox is utilized in manually-managed 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 within 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 ensures that the drive shaft is certainly locked when the reduction gearbox isn’t running. The fully sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep carefully the gear oil at a minimal pressure under all Gear motors for Greenhouse conditions, even at high temperature ranges. Thanks to the use of an growth chamber, the PolyGearbox can be installed in any position. 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 optimum condition because of 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 comes with an FT85 engine assembly flange, to which the right IEC standard motor can simply be installed (EN 50347).

The PolyGearbox includes 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 switch 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 feed-through.
