"Quality roof
ventilated tunnel house"
Redpath's classic vented arch combines the efficiency
of a simpler tunnel house construction with a quality rack and pinion controlled
full length "gutter roof ventilation system. The vented arch design
lends itself to high quality flower and seasonal vegetable production.

Popular in Europe, the "gutter vent" design offers
a grower the added flexibility of being able to open the roof vent partially
in wet conditions, without allowing excessive weather to drive in.
When closed, the roof ventilators utilise the internal walkthrough gutter
to shut down onto. This provides efficiencies in both performance
and cost. The roof vents are operated by automatic electric motor
gearboxes as a standard feature. A selection of Redpath computer
controllers are available for accurate monitoring and control.

The 7500 FI vented arch model also includes the
Redpath Eziwinder roll up sidewall ventilation system for the full length
of both sidewalls as standard. These are manually operated, however,
they can be easily automated as an optional extra.

Vented Arch is supplied with heavy-duty long-life
singleskin 200 micron (8mil) Duratough greenhouse film cladding or a thermally
efficient twinskin cladding may be fitted if required.
