TSL
General Information
Description
The TSL range of labyrinth natural ventilators provides for the extraction of large volumes of warm air and / or smoke in an economic and energy efficient manner.
The TSL range is specifically intended and designed for industrial applications where weather resistant ventilation must be maintained under all weather conditions.
TSL ventilators are designed for minimum maintenance in accordance with NEN and ISO 9002 standards, using corrosion resistant aluminium to provide a long and trouble free operational lifespan.
The lightweight, low profile, self supporting ventilators provide the high levels of ventilation required in industries with very high internal heat loads, from solar heat gains plus machinery or other hot production processes, where the hot and possibly contaminated air must still be removed during bad weather conditions, including rain or snow.
In many instances the machinery within a building produces high internal noise levels, and sound attenuation to limit or prevent noise breakout for environmental purposes is a requirement for the ventilation system.
The labyrinth ventilator construction with its vertical air guide vanes provides a limited level of sound attenuation. This level of protection can be enhanced by the incorporation of purpose designed sound attenuation boxes, to meet any practically achievable design requirements for noise reduction. These attenuation boxes can be mounted above the roofline, or may be recessed into the building where a lower profile is required.
Operating Principles
Warm air rises due to thermal convection and large quantities of warm air or smoke can be removed from a building using this natural ventilation principle.
The system consumes no electrical power to extract the air and the ventilation effect may be increased by external wind action.
The boxes are fitted with vertical internal air guide vanes which collect rain water and shed it onto the roof at the base of the ventilator.
The drainage system is self cleaning under the action of the water and this operates without any effect on the ventilation performance.
The TSL ventilator has an internal pivoting damper system which provides full volume control as required. This design allows an almost unobstructed passage through which the air can flow for maximum aerodynamic performance.
The TSL ventilator is a fully tested and approved fire ventilator which complies with the requirements of BS : 7346 : Pt 1 and DIN 18232.
Applications
The TSL is useful for:
- Steelworks;
- Glassworks;
- Power stations;
- Paper Mills;
- Processing plants or other buildings with similar high heat or large volume ventilation requirements.
Specifications
Modular construction to allow long, continuous, site assembled ventilators comprising a mounting base section, a labyrinth section with internal air flow and drainage vanes, volume control dampers plus attenuator boxes with attenuation panels if required. Construction is in corrosion resistant aluminium with stainless steel fixings throughout.
Despatching
The TSL labyrinth ventilators are assembled and delivered in preassembled modules and are built up on site, to form ventilators of unlimited lengths.
The standard product is supplied in mill finished aluminium but coating in polyester powder paint to any RAL colour selected from the standard Bovema range is available.
The self-supporting construction of the ventilators makes them suitable for installation onto any type of roof construction.
The base flanges are manufactured to match individual project requirements and are fully welded to ensure that they are completely waterproof.
