Coltlite CL

Product catalog summary
Overview: The Coltlite CL is a high-performance natural louvred ventilator designed for both day-to-day and smoke control ventilation, suitable for industrial and commercial buildings. It offers high acoustic, thermal, and aerodynamic performance and is CE marked, conforming to EN 12101-2 and EN 14351-1 standards.
Key Features and Benefits:
  • Versatility: Functions as a façade element or smoke/air damper, suitable for both low-level air inlet and high-level extract.
  • Durability: Constructed from corrosion-resistant aluminium alloy with stainless steel fixings.
  • Safety: Optional device to reduce speed and force of closing louvres to prevent finger trapping.
  • Design: Narrow framework for increased aerodynamic efficiency, with motors concealed within the frame.
  • Installation and Maintenance: Delivered fully assembled with easy access to mechanisms via removable panels.
Product Variants:
  • CLT: Thermally broken frames, double glazed louvres, high acoustic and thermal performance.
  • CLN: Non-thermally broken frames, double glazed louvres, high acoustic and thermal performance.
  • CLS 45: Frameless single glazed louvres, smooth design, not certified for smoke control.
  • CLS: Frameless single glazed overlapping louvres, high aerodynamic performance.
  • CLST: Thermally broken frames, flat glazed appearance, not certified for smoke control.
  • CLET: Frameless controllable louvres, high wind load resistance, not certified for smoke control.
Technical Specifications:
  • Frame and Louvres: Available in single, double, or triple glazed options with various glass thicknesses.
  • Controls: Options include pneumatic, manual, 230v AC, or 24v DC electric controls.
  • Performance: High resistance to fire, tested and certified for performance as a façade element.
  • Dimensions: Vent overall width ranges from 300mm to 2000mm, height from 250mm to 3000mm.
Applications: Suitable for naturally ventilated buildings requiring good aerodynamic and measured free area ventilation, achieving high acoustic, thermal, and aerodynamic performance.
Technical Specifications and Performance:
  • Ventilator Design: Designed to resist design wind loads and tested for performance as façade elements according to EN 14351-1.
  • Materials and Construction: Options include non-thermally broken extruded aluminium frames with single glazed louvres, and thermally broken frames with double-glazed louvres. Glass thickness varies from 8mm to 34mm, with toughened and polished edges.
  • Dimensions: Vent overall width ranges from 300mm to 1600mm, and height from 250mm to 3000mm. Blade pitch varies between 168mm and 355mm.
  • Controls: Available in manual, 24v DC, 230v AC electric, or pneumatic options.
  • Performance Ratings: Air permeability (EN 12207) ranges from Class 2 to Class 3, resistance to weather (EN 12208) from Class 2A to Class 4A, and resistance to wind (EN 12210) from Class B3 to Class C5. U values and CV values are specified for certain models.
Project Applications:
  • COLTLITE systems have been used in various projects worldwide, including educational institutions, hospitals, hotels, and commercial buildings in the UK, New Zealand, Australia, Holland, France, and Germany.

HIGH PERFORMANCE FEATURES AND BENEFITS A WIDE RANGE OF APPLICATIONS Coltlite has high aerodynamic, acoustic and thermal performance, and has a high resistance to the effects of fire. Full performance data is given later on in this leaflet. Coltlite is classed as a dual purpose ventilator, 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...
