The EP PolyGearbox (RPG) is a compact and light-weight reduction gearbox with a built-in limit switch system that’s suitable for assembly of a locally available electric engine. The PolyGearbox is used in manually-controlled or climate-managed ventilation and display screen systems in poly greenhouses. The quick and easy-to-installEP PolyGearbox is rainproof and windproof. The PolyGearbox includes a high Gear motors for Greenhouse protection course (IP65) and can be utilized in an ambient temperature of 0-60 °C.
The low-noise PolyGearbox has a gearwheel transmission and a worm wheel transmission, which are integrated within an aluminium precision housing. The self-braking worm wheel tranny means that the drive shaft is definitely locked when the decrease gearbox isn’t running. The completely sealed reduction gearbox comes with an growth 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 use of an growth chamber, the PolyGearbox can be installed in any placement. There are no restrictions, since there is no need for a bleed connect. The sealed decrease gearbox keeps the gear oil of the PolyGearbox in optimal condition because of 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 comes with an FT85 electric motor assembly flange, to which the right IEC standard engine can certainly 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 within an built-in chamber and is 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 certainly 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.
