The electrically operated Compact Door has no counter-balancing
springs or weights which require adjustment or regular maintenance.
The simple, unique guiding system minimises the forces on the
moving parts. Manual chain operated doors include springs.
Compact doors are manufactured to the highest European Standards.
It is a requirement of the Health and Safety Executive that all
powered doors comply with the machinery Directive 89/392/EEC and
carry the CE symbol. Every electrically operated Compact Door
complies with this directive.
The Compact Door is constructed from aluminium sandwich panels,
610mm high and 40mm thick with CFC free polystyrene fill. The
compact door has seals around the perimeter and between the panels.
The door is driven by a high quality three phase motor. The motors
are available in frequent-use, medium-speed and high-speed operation.
The high-speed version can achieve a speed of up to 0.5 m/sec
on a door 4.00m w x 4.25m h.
