The EP PolyGearbox (RPG) is a compact and light-weight reduction gearbox with an Gear motors for Greenhouse integrated 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 definitely rainproof and windproof. The PolyGearbox includes a high protection class (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 in an aluminium precision housing. The self-braking worm wheel transmitting ensures that the drive shaft is usually locked when the decrease gearbox is not running. The fully sealed reduction gearbox has an growth chamber with a diaphragm to keep the gear oil at a low pressure under all conditions, even at high temps. Thanks to the use of an expansion chamber, the PolyGearbox could be installed in any placement. There are no limitations, because there is no need for a bleed plug. The sealed decrease 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 course s3-30%, with a maximum activation time of 25 minutes.

The PolyGearbox reduction gearbox has an FT85 electric motor assembly flange, on to which the right IEC standard engine 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 at the end positions. The limit switch system is installed in an integrated chamber and is usually enclosed by an impact-resistant plastic cover. The limit change system is obtainable and simple to adjust. The limit change 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 comes with an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
