The EP Greenhouse Gearbox is a concise and lightweight reduction gearbox with an integrated limit switch system that is ideal for assembly of a locally available electric motor. The Gearbox is utilized in manually-controlled or climate-controlled ventilation and display screen systems in greenhouses. The quick and easy-to-installEP Gearbox can be rainproof and windproof. The Gearbox includes a high protection course (IP65) and can be utilized within an ambient temperature of 0-60 °C.
The low-noise Gearbox for Greenhouse has a gear reduction motor 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 locked when the reduction gearbox is not running. The completely sealed reduction gearbox has an expansion chamber with a diaphragm to keep the 
gear essential oil at a low pressure under all circumstances, even at high temperatures. Thanks to the use of an expansion chamber, the Gearbox can be installed in any position. There are no restrictions, since there is no dependence on a bleed connect. The sealed reduction gearbox keeps the apparatus essential oil of the Gearbox in optimum condition because of its entire operating life time. The Gearbox is suitable for discontinuous use, working course s3-30%, with a maximum activation period of 25 minutes.
THE APPARATUS box reduction gearbox comes with an FT85 motor assembly flange, to which a suitable 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 at the end positions. The limit change system is installed within an integrated 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 definitely 40 or 64 revolutions of the drive shaft. The cabling is linked in spring-clip connections. The Gearbox has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through.
The Gearbox for greenhouse comes with 16 teeth 5/8”x3/8” sprockets, keys and fasteners. The accompanying chain couplings and assembly plates can be found as accessories.
Optimum drive torque of 150 Nm or 450 Nm.
Rotational speeds of 3 or 5 rpm for a mains frequency of 50 Hz or 3.6 or 6 rpm for a mains frequency of 60 Hz in the event of program of 4-pole electric motor.
