The EP PolyGearbox (RPG) is a compact and light-weight reduction gearbox with a built-in limit Gear motors for Greenhouse switch system that’s suitable for assembly of a locally available electric electric motor. The PolyGearbox is utilized in manually-controlled or climate-managed ventilation and display systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is certainly rainproof and windproof. The PolyGearbox includes a high protection course (IP65) and can be used 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 transmission ensures that the drive shaft is definitely locked when the decrease gearbox is not running. The fully sealed reduction gearbox has an expansion chamber with a diaphragm to keep carefully the gear oil at a low pressure under all circumstances, even at high temps. Thanks to the use of an growth chamber, the PolyGearbox can be installed in any position. There are no limitations, because there is no need for a bleed connect. The sealed reduction gearbox keeps the apparatus 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 comes with an FT85 electric motor assembly flange, on to which a suitable IEC standard 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 by the end positions. The limit change system is installed in an integrated chamber and is enclosed by an impact-resistant plastic material cover. The limit switch system is accessible and easy to adjust. The limit switch system’s optimum switching range is usually 40 or 64 revolutions of the drive shaft. The cabling is linked 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.
