NKV-G
General Information
Description
Bovema wall louvres type NKV-G offer economic methods for the provision of air inlet into buildings.
The systems are suitable for industrial or commercial buildings where ventilation is required. The Architecturally designed multi-purpose louvres are manufactured in accordance with NEN-EN-ISO 9001 quality control standards and are fabricated from high quality corrosion resistant aluminium for guaranteed product operation and quality NKV-G louvres may also be manufactured in stainless steel for special purposes.
The lightweight construction allows the production of a wide range of products, which can be installed to meet almost any Engineering or Architectural requirement.
An internal mullion system allows for a "Click Fix" blade installation process with no external fixings to spoil the Architectural appearance, whilst ensuring full blade support and alignment.
The operable louvres have internal damper sections, which provide for volume control without any movement of the external blades.
The NKV-G louvres are formed from high quality aluminium or stainless steel sheet, with profiles designed to provide a strong louvre blade with maximum protection against rain penetration. The operable louvres have alternate fixed and operable blades, so that in the open or closed positions the outer blade remains in a fixed position. A wide range of ancillary fittings from stainless steel bird guards to bolt on sound reduction attenuators is available and a wide range of controls enable the louvres to open exactly at the right opening angle based on all weather conditions. Fixed blade continuous louvres may also be used for Architectural screening purposes.
Operating Principles
The range of Bovema Louvres are all intended to allow fresh air to flow into a building and the louvres divide into fixed or operable products.
All louvres have a fixed outer blade, which is angled at 45 Deg. to carry away rain from the interior of the building, by gravity aided by the drainage facilities built into the louvre blades. Where additional weather protection is required for continuously open louvres, special two pass louvres with an additional set of internal blades can be provided.
Operable louvres have an inner damper type blade, which can be operated to fully or partially close off the opening to restrict the airflow.
Manual or powered operating systems are available. 230V A/C or 24 V D/C electro-motor controls are available to operate the louvres and these can be preset to any specific required angle. Pneumatic controls are also available for fully open / close operation or a 2 step system of control. Both the electric and pneumatic systems can be operated in conjunction with remote control panels allowing interface facility for smoke or environmental control operation, in combination with wind or rain detection systems.

Despatching
The NKV-G wall louvres are supplied as fully assembled units suitable for site assembly as appropriate and are quality assurance tested prior to despatch.
Standard units are supplied in mill-finished aluminium, but Polyester Powder Painting to any colour selected from the standard Bovema range may be supplied.
Additional bird screens, sound attenuators, sprinkler shields and open / close louvre position indication switches can be provided.
The lightweight construction and the fully welded flanges allow the incorporation of Bovema louvre systems into most building design projects.
