Buildings are for people

Details

Without electric power, sensors or human intervention, Ventient Natural Ventilation technology automatically controls ventilation dependent on ambient temperatures, optimising the benefits of natural ventilation without introducing air that is too hot or too cold. 

Product Description

Using state-of-the-art temperature perception technology, Proctor Ventient is an environmentally friendly technology that does not require the use of electric power. By using the physical characteristics of a unique Shape Memory Alloy (SMA) Proctor Ventient can adjust the volume of ventilation levels depending on temperature. 

Amongst the wide range of patented Proctor Ventient products is the stylish and sleek Ventient SCW-N unit which can be used in curtain walls with minimal impact on the exterior or interior design finish.

Proctor Ventient will usually work in automatic mode but most devices will also offer the ability for occupants to manually close the ventilation if required. The devices can be also be accessed to replace filters for ease of maintenance.
