Side furling sails
In winter, barns tend to be completely closed, but ammonia and carbon dioxide accumulate in the barn, which must be ventilated.
The tarpaulins are automatically controlled by an ERSTA control unit.
Tarpaulins are produced in lengths of one section up to 60 m. Two sections up to a total length of 100 metres can be powered by only one motor.
The opening height of the tarpaulin is up to 425 cm. The drive is fully automatic; it can also be manual/electric or manual/crank.
The tarpaulin is made of woven PVC with optional colour, grammage and light transmittance. The tarpaulin material can be welded.
