Gilberts (Blackpool) - Mistrale Air Distribution & Natural Ventilation

External Standard High Performance Louvres - Passive Natural Ventilation Systems

Natural ventilation, unlike mechanical fan forced ventilation, simply uses the natural pressure differential force of air movement, wind and buoyancy to deliver a steady supply of fresh air for building ventilation and cooling.

Naturally ventilating a building offers the best of both worlds combining little or no energy consumption with low capital costs whilst still providing adequate fresh air and temperature conditions throughout the year. With plant room also eliminated, services space minimised and lower service / maintenance costs, Natural Ventilation now makes for one the most practical choices of the day.

Gilberts Mistrale Natural Ventilation range is a complete, all new design that incorporates patented design features which position it at the leading edge of modern natural ventilation design. Suitable for both stack effect and wind driven systems Mistrale comprises of all of the key the components you will need to design a robust, efficient and extremely effective natural ventilation system.

Key Features

• Mistrale – 50, 75 & 100 solutions provide both large and small format cassettes to enable installation into both windows and walls.
• External Louvres – Patented louvre design offering high weather performance in an economical single bank assembly. With a good free area and low pressure resistance this louvre allows for maximum design cost efficiency.
• Regulating Damper – Close control with the ability to finely regulate airflow accurately to meet the ventilation and temperature requirements are vital for good natural ventilation. Our patented insulated blade damper design with full insulated casing not only offers very low leakage when closed but can also provides a U-value of less 1 Watt/m²/K
• Heating / Cooling Coil – Optional fitting which allows the unit to combine ventilation with a heating or cooling function.
• Fascia Grille – With a wide variety of both standard and bespoke fascia grilles we can provide unique grille design solutions that combine good airflow with a visual style in keeping with building design.
• Penthouse Louvre – Gilberts intake / exhaust penthouse turret can be specifically manufactured in a wide variety of configurations to suit the system design or aesthetic parameters. The turrets can be designed to suit wind driven systems or stack effect with internal partitions and dampers providing for full and accurate air movement control. All penthouse units are of our patented high weather efficiency class ‘A’ design to eliminate weather ingress and can be fitted on to both flat and pitched roofs.

The Mistrale system has been developed in conjunction with a matching controls package that knits the whole system together. Room CO² and temperature sensors can interface with the unit controls to fully manage the complex relationship between airflow, temperature and air quality to maintain the perfect environment.

Gilberts Natural Ventilation engineers are on hand to discuss whether wind driven, stack driven or, in more challenging areas, consideration of mixed mode strategy that includes mechanical ventilation is appropriate for your project and can also advise on a controls package to match.
