Motorised Louvres

All units are purpose designed to suit clients individual requirements and the most requested specification is for pre-galvanised mild steel fully welded casings housing pre-galvanised mild steel double skin ‘z’ section type parallel operating blades mounted on zinc plated spindles running in nylon bushes. The maximum blade length based on face velocities up to 1250 FPM (6.35m/sec) is 2000mm but units having internal casing width in excess of this figure will have banks of blades with mullions sited to cause the minimum restriction in air flow. Louvres suitable for higher air velocities can be supplied but E.A.T must be advised accordingly before manufacture commences. To cater for site conditions and global installations we can offer alternative constructions of 304 or 316L Stainless steel, Mill finish or Marine Grade Aluminium:- Black or Hot dip galvanised Mild Steel. All units can be offered with a wet paint or powder coated finish. If the Louvres are to be sited or operated in tempartures exceedeing 80 degree C once again we should be advised of such at the outset. 12mm Sq. Mesh Guards are fitted over the blades dependent upon the position of installation to comply with CE certification. Apart from the basic manual operation the louvres can be fitted, suitable for safe or hazardous areas, with pneumatic open/close Actuators, Spring assisted Pneumatic actuators, open/close modulating, spring return electric motors, fast operating open/close electric Linear Actuators.
