Coltlite natural louvred ventilator

Coltlite is a natural louvred ventilator suitable for natural day-to-day building ventilation, as well as smoke control. Most variants conform to both EN 12101-2 as smoke ventilators and EN 14351-1 as natural ventilators. All products are CE marked. It can provide inlet and extract ventilation as well as the entry of natural daylight for most kinds of industrial and commercial buildings. It achieves high acoustic, thermal and aerodynamic performance. It is suited for installation into the façade.

Coltlite CLS

Dimensions / size range

From 300mm to 1800mm in width, and from 250mm to 3000mm in height as one module.

Frame

Non thermally broken, 47mm deep

Louvres

  • 8mm / 10mm / 12mm overall clear toughened, float or laminated glass with overlapping blades.

Louvre dimensions

Louvre height from 205mm to 395mm.

Blade pitch 155 to 355mm (depending on overall size of complete unit) with central pivot point.

Colours/ finishes options

  • Polyester powder paint to a RAL colour, standard 75 mµ
  • Anodised, standard 20 mµ

Fixing options

  • Fixing to curtain walling using 20 to 30 mm thick non thermally broken glazing frame adaptor
  • Fixing to structural opening using either through frame or strap fixings.

Controls options

  • Lever
  • Crank handle
  • 230 volt AC motor
  • 24 volt DC motor
  • Pneumatic cylinder

Frame mounted and painted motor (hidden behind side frame profile) positioned at:

  • Top
  • Bottom

on either side frame and with a typical operation time of 32 seconds.

  • Optional device to reduce the speed and force of closing louvres, to reduce the risk of finger squeezing (some electric versions only).

If used as a smoke ventilator, activation is either by local thermal fuse which opens the unit at a pre-selected temperature, or by responding to an external release signal.
