This makes them the ideal solution for roll up side ventilation systems. Either wired to a low-cost controller & thermostat or linked to a sophisticated environmental control system, these offer a great value automatic ventilation solution.
Bare Drive Shaft Diam: 16mm OD. Drive Shaft Coupling: 26mm ID / 36mm OD. Electrical Input: 24vDC +/- 10%.
24vDC driven, planetary geared, motorised vent winder with an inbuilt limit switch. Multiple applications for both fixed polytunnels and fruit-growing field tunnels, including roll-down side vents, end ventilation screens, rack & pinion vents, roof vents etc.
Easily installed to existing ventilation systems by attaching the motor’s drive shaft to the vent drive tube using the couplings provided. For roll-up/roll-down screens the motor can then be either attached to a vertical support tube (guide tube) using a roller guide carriage or attached directly to a pivoting telescopic arm. Vertical guide tubes and telescopic arms can also be supplied – call 01282 873120 for details.
Three models available:
40Nm,
90Nm
150Nm (normal operating loads).
As a general guide, every metre of ventilation screen requires 1Nm of torque, therefore a 40m roll-down screen would require a 40Nm motor. If in doubt, phone our sales team with your requirements before ordering.
Supplied with a drive tube coupler (26mm I.D. x 36mm O.D.) to suit a range of drive tubes, but we can make couplers to suit any size of drive tube. Roller guide carriages are available for mounting on to 32-35mm O.D. guide tubes, or alternatively, the motor can be mounted directly on to a pivoting telescopic arm.
These motors require a driver unit for operation. One driver unit can operate up to two motors under normal operating loads. For fully automatic (temperature-based) operation an automatic controller is also required unless you’re using your existing control panel.
