Twin roll screen system
To achieve a better climate greenhouses are getting higher and longer, so the twin roll screens must be equally so.
Huima Specials has developed a special shaped gearbox to meet these demands. Despite being light, it is the strongest twin roll motor available with torques up to 220 Nm.
Due to this special design this strong gearbox is small enough to require no more space than the width of a post. This space-saving shape ensures there will be no collision with for instance automatic transport and enables you to make the utmost use of the greenhouse surface.
When closed, the twin wall forms a solid barrier, no special blackout strokes are needed for insulation between motor and posts.
For extra long roll screen there is a gear motor available that can be placed in the centre of the screen to avoid torsion in the roll tube
The twin roll motor can be equipped with both a 3 phase and a 1 phase motor.
For small screens, or when operating on a low frequency, Huima has a hand-operated gearbox. Its unique design assures that every tube can be mounted directly to the outcoming shaft of this gearbox.
