greenhouse gearbox

The EP PolyGearbox (RPG) is a compact and lightweight reduction gearbox with a built-in limit switch system that’s ideal for assembly of a locally available electric engine. The PolyGearbox is used in manually-managed or climate-controlled ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox has a high protection course (IP65) and can be used within an ambient temperature of 0-60 °C.

The low-noise PolyGearbox has a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel transmission ensures that the drive shaft is usually locked when the reduction gearbox is not running. The completely sealed reduction gearbox has an expansion chamber with a diaphragm to keep carefully the gear essential oil at a low pressure under all conditions, even at high temperature ranges. Thanks to the usage of an growth chamber, the PolyGearbox can be installed in any placement. There are no limitations, because there is no need for a bleed plug. The sealed reduction gearbox keeps the gear oil of the PolyGearbox in Gear motors for Greenhouse optimum condition for its entire operating life time. The PolyGearbox is ideal for discontinuous use, working course s3-30%, with a maximum activation time of 25 minutes.

The PolyGearbox reduction gearbox has an FT85 electric motor assembly flange, to which the right 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 switch system is installed within an integrated chamber and is certainly enclosed by an impact-resistant plastic-type 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 connected in spring-clip connections. The PolyGearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
