Windvent » Introduction

The Midtherm Windvent is a natural ventilation system that operates purely on the aerodynamic principles of a passive stack system. Simply put, the roof-mounted Windvent terminals capture clean, fresh air and introduce it into the room space below whilst simultaneously removing the existing stale air. The only energy consumption required is to power a low voltage controller unit to limit the input of natural air. Windvent is available as either a balanced (NV) or passive stack (PS).

With many companies and individuals taking a more positive approach to environmental issues, an increasing number are seeing the benefits of naturally driven systems in their working environment and the difference it is making to their energy bills, environmental policy and the health of their employees.

Cost Savings

The system is powered primarily by aerodynamic forces and so the only power required is to run the low voltage controller unit. This offers substantial costs savings compared to traditional mechanical ventilation systems that can potentially run into thousands of pounds each year.

Health Benefits

By it's nature, the Windvent system offers a natural solution to health problems commonly associated with mechanical air conditioning units. Rather than re-circulating stale air (and possibly germs), the Windvent system is continually removing stale air and replacing it with a fresh supply. The system takes air from the roof level eliminating a healthy proportion of pollution, including hazardous carbon monoxide from roadside traffic that is a common issue with low level ventilation methods.

Suitable Applications

The Windvent system is suitable for many applications including schools, offices and hospitals. It is used in private, local authority and commercial premises including gymnasiums, colleges, universities, reception areas, store rooms, changing rooms, libraries, meeting halls and is suitable for specialist applications. It is also an ideal solution for delivering a 'fresh' air supply to areas where conventional room ventilation is difficult due to critical noise issues.

The Ideal Solution

The Windvent offers architects and consulting engineers not only a natural and environmentally-friendly solution but an acoustically efficient, economical and aesthetic answer to ventilation needs.

Terminal Design

External terminals can be designed in keeping with the architectural design and aesthetics of the buildings or can be manufactured to be of a contrasting appearance, adding a feature aspect to the building. Louvres are designed to ensure the maximum available free area of the unit is utilised, whilst maintaining weather integrity at all times.

Manufacture & Installation

Units can be installed on almost all roof types including flat, pitched and even on the roof apex where appropriate. All units are manufactured to BS EN ISO 9001 and are fully welded and constructed using corrosion resistant aluminium and fitted with internal acoustic material. Adjustable dampers and transfer grilles are manufactured from anodised aluminium or perforated stainless steel panels. The units may be powder coated to your specifications in any RAL colour of your choice.

The ductwork for the units can pass through any floor level to transfer air within the building. The units are capable of being linked to the buildings BMS to ensure dampers are fully closed in the event of a fire. Windvent units can be controlled via master control panels, room temperature sensors and CO² sensors. We also offer a manually operated system called ‘Teleflex’ where the dampers can be opened and closed by use of a rotating lever operated by the room occupants when required.
