Coltlite

Coltlite Cl and Coltlite CL3 are natural louvred ventilators suitable for natural day to day and smoke control ventilation in vertical application.

Overview

Coltlite is an award-winning 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.

The new Coltlite CL3 features an incredibly robust and innovative façade ventilator. It comes equipped with completely new installation tools, and its performance values leave nothing to be desired in terms of energy-saving. The Coltlite CL3 has a huge range of applications, it is the ideal solution for day-to-day ventilation and smoke control in commercial buildings, offices, shopping centres, laboratories and ultra-modern industrial buildings.

Its form and function makes it particularly suited to naturally ventilated buildings where good aerodynamic and measured free area ventilation is required while achieving high acoustic, thermal and aerodynamic performance. Whilst it is primarily designed as a glazed element of the building envelope, it can also be applied as a high specification fire, smoke and air control damper. Typical applications are hospitals, schools, shopping centres, apartments and commercial buildings.

A wide range of applications

Most versions of Coltlite are classed as dual purpose ventilators, providing both day-to-day and smoke control ventilation. It can also be installed either for low level air inlet or for high level extract. Coltlite is also often used as a termination piece for large ducted or air handling systems. Glass versions allow the entry of natural daylight, and a wide range of infill panels are available. Options include pneumatic, electronic or manual controls and a wide range of louvre types, accessories and finishes.

Coltlite can be used as an automatic opening smoke vent in certain instances. To learn more about AOV systems, check out our AOV Systems page.

Features and benefits

  • High performance – Coltlite has high aerodynamic, acoustic and thermal performance, and has a high resistance to the effects of fire. See the leaflet for further details.
  • Certified performance – All versions of Coltlite except CLS45 have been exhaustively tested and certified to EN 12101-2:2003 as dual purpose ventilators in accredited third party test laboratories. In addition all ventilators have been tested to EN 14351-1 which guarantees their performance as façade elements. All ventilators are CE marked accordingly.
  • Extremely well insulated – Coltlite CL3 achieves a Uw-value of up to 1.0 W/m²K.
  • High performance in fire – One of the fire consultant’s main design considerations is to make sure that any smoke emitted by a fire is evacuated from the building in a controlled fashion. Special arrangements need to be considered, in particular for escape routes such as in stairwells. Coltlite is very suitable for protecting escape routes since it has a high aerodynamic efficiency, opens quickly, has large openings and does not get in the way of people trying to leave the building.
  • Superb noise reduction – Up to 45 dB with the Coltlite CL3.
  • Unique louvre mechanism – Coltlite CL3 comprises a unique louvre mechanism which enables heavy louvre blades to be attached, for easy installation and maintenance.
  • Easy to install – Coltlite is delivered fully assembled to site into a structural opening or curtain walling. It must be installed in the vertical. It has a wide range of base profiles to suit most sheeting, curb or glazing applications.
  • Safe in operation – With electric versions there is an optional device to reduce the speed and force of the closing louvres in order to reduce the risk of finger trapping.
  • Durable – The frame is manufactured from tough, corrosion resistant aluminium alloy, with stainless steel fixings.
  • Quality of manufacture – Coltlite is manufactured under the ISO 9001 quality standard. Each unit is given a functional test before despatch.
  • Aesthetic design – Coltlite uses narrow framework and motors can be hidden within the frame or are small in size.

Detailed description

Coltlite CL3 ventilator providing highly efficient natural day-to-day ventilation and smoke control by making use of the natural buoyancy of warm air. The ventilator comprises frame and louvres. It is thermally broken and is made of extruded aluminium profiles with an alloy to the EN AW-6063 materials data sheet.
The ventilator incorporates concealed fittings and a lever and rod system to accommodate the drives with concealed mechanisms.
The unique louvre mechanism allows for quick attaching of heavy louvre blades for comfortable installation and maintenance. The units can be supplied with built-in louvres or, on request, with separately packed louvres.
