The EP Greenhouse Gearbox is a concise and lightweight reduction gearbox with a limit switch system that is suitable for assembly of a locally available electric motor. The Gearbox is utilized in manually-managed or climate-managed ventilation and screen systems in greenhouses. The quick and easy-to-installEP Gearbox is rainproof and windproof. The Gearbox has a high protection class (IP65) and can be used within an ambient temperature of 0-60 °C.
The low-noise Gearbox for Greenhouse includes a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel tranny means that the drive shaft is certainly locked when the reduction gearbox is not running. 
The fully sealed reduction gearbox comes with an expansion chamber with a diaphragm to keep carefully the gear essential oil at a minimal pressure under all circumstances, even at high temperature ranges. Thanks to the use of an expansion chamber, the Gearbox can be installed in any position. There are no restrictions, because there is no need for a bleed connect. The sealed reduction gearbox keeps the apparatus oil of the Gearbox in ideal condition because of its entire operating lifetime. The Gearbox is ideal for discontinuous use, operating course s3-30%, with a maximum activation time of 25 minutes.
The Gear box reduction gearbox has an FT85 motor assembly flange, on to which the right IEC standard motor can simply be installed (EN 50347).
The Gear box has 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 included chamber and can be enclosed by an impact-resistant plastic-type material cover. The limit switch system is accessible 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 linked in spring-clip connections. The Gearbox comes with an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
The Gearbox for greenhouse includes 16 teeth 5/8”x3/8” sprockets, keys and fasteners. The accompanying chain couplings and assembly plates are available as accessories.
Optimum drive torque of 150 Nm or 450 Nm.
