TMS-DR
General Information
Description
The Bovema TMS-DR louvred ventilator, with weathered side sections, is designed to provide an economic, non-powered method for the removal of large quantities of warm air, and/or smoke.
The ventilator is particularly suitable for use in industrial buildings where low cost natural ventilation is required with a reduced weathered ventilation facility during inclement weather.
Each slim line, multi purpose, ventilator is manufactured to NEN-EN-ISO 9001 quality standard control, and is designed and tested to comply with various national standards for smoke ventilators such as DIN 18232 in Germany, BS: 7346:Pt 1 in the U.K. or NFS 61937 in France.
The construction is formed using the highest quality corrosion resistant aluminium to ensure low maintenance.
Various methods of operation, including pneumatic or electric systems are available.
The overall design results in a versatile, economic ventilator suitable for a wide range of applications.
Operating Principles
Warm air in a building rises due to thermal convection and large quantities of warm air and / or smoke can be evacuated using this natural ventilation principle. The ventilation effect can be increased due to external wind action.
The TMS-DR ventilator has operable top louvres, which provide substantial daily ventilation or smoke / heat evacuation. Operable and weathered side ventilators provide a lower level of weather-protected ventilation. The side dampers operate outside of the top louvre air-stream so the aerodynamic performance of the top louvres is not compromised. The top louvre and side dampers can be operated independently, to allow maximum variation of the level of ventilation. When used as a smoke extract ventilator, the louvre blades are opened on a priority control basis.
Operating systems can include rain or other environmental systems to protect the building interior.
The louvre section has specially designed interlocking blades, to ensure weather protection. These are angled to allow translucent louvres to be self-cleaning. The louvre blade pivots are outside the airsteam to ensure maintenance free operation and specially designed seals, on each side of the blades, reduce unnecessary energy losses.
The bottom hung side dampers offer minimum resistance to airflow and when closed they do not obstruct the louvre drainage facility.
Applications
The TMS-DR is useful for:
- Industrial Buildings;
- Warehouses;
- Logistics centres;
- Shopping Centres;
- Etc.

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