TMS-DG
General Information
Description
The Bovema TMS-DG Wall Louvre provides an economic means of introducing large quantities of fresh air into a building. As a certified smoke extract ventilator the louvre may also be used for smoke extract in the event of a fire, where wall extract systems are acceptable.
The TMS-DG louvre is particularly suitable for industrial and commercial buildings where high levels of ventilation are required and it is commonly used as an operable air inlet for high heat or smoke extract systems, operating in conjunction with roof extract louvres or fans.
The TMS-DG louvre is available with solid or glazed blades and is therefore ideal for installations where ventilation plus Daylighting is required. The large bladed aesthetically pleasing louvres are manufactured to NEN-EN-ISO 9001 quality control standards and are designed and tested to comply with the various national standards for smoke ventilators, for example DIN 18232 in Germany, BS: 7346: Pt 1: 1990 in the UK and NFS 61937 in France.
The ventilators are formed from high quality corrosion resistant aluminium, to ensure low maintenance requirements. The lightweight construction allows for the manufacture of large individual products and the full-unrestricted opening areas provide a very economic solution to meet wall louvre requirements.
As a variation of the TMS-D roof louvre the TMS-DG wall louvre is fully sealed when closed, with overlapping blades to ensure top class water shedding characteristics. Blade seals on the insulated louvres enhance the heat loss protection available.
Various methods of operation using pneumatic or electric actuators are available.
Operating Principles
TMS-DG wall louvres are designed to allow large quantities of air into buildings with very little loss in air pressure as the air flows through them when open. They are particularly compatible with natural or powered extract systems for smoke ventilation or high heat industrial systems. When closed the louvres are fully watertight even in driving rain conditions. Partial opening of the louvres can also provide reduced levels of ventilation with limited weather resistance.
Various control systems are available and the louvres can be operated in conjunction with other roof extract ventilators to meet various environmental requirements.
Specially designed interlocking louvre blades ensure leakage is prevented when the louvres are closed, and the blade hinges are positioned outside of the air stream to allow maintenance free operation.

Despatching
TMS-DG louvre ventilators are supplied fully assembled and each unit is test operated before despatch.
The standard unit is manufactured in natural mill finished aluminium but a Polyester Powder Paint finish to any standard RAL colour, selected from the Bovema range may be specified for all the aluminium components. Other optional items such as bird screens, insect mesh, sound attenuators and sprinkler shields are also available.
The ventilator base and flange units are of fully welded construction, with final flange sizes fabricated to suit individual project requirements.
The lightweight construction and wide range of base profiles allows the TMS-DG unit to be installed onto almost any type of cladded, built up or glazed wall construction.
The overall construction allows for simplicity of installation to ensure watertight connection.
