THE CLIMATE CHANGE REALITY Greenhouse gas emissions continue to drive global warming and the five-year period to 2018 was the hottest ever recorded. The world is nearly one degree warmer than it was before widespread industrialisation, and the 20 warmest years on record have been in the past 22 years according to the World Meteorological Organization (WMO). According to the Committee on Climate Change if the global temperatures rise by 2ºC, around 2.6 million people in the UK will be impacted by the significant risk of flooding. OUR CHALLENGE The UK government has now legislated for net...

Natural ventilation supplies fresh air to a building or room by utilising the passive effects of wind speed or differences in internal and external air pressure. It is a sustainable, low carbon ventilation system that does not use fans or pumps making it extremely cheap to run whist providing a comfortable and healthy indoor environment. Monodraught first launched Windcatcher in 1991 and have been constantly innovating our concept for modern applications. In the last two decades nearly 27,000 Monodraught Windcatcher units have been successfully sold and installed in UK, France, USA and New...

PRODUCT RANGE Ventsair systems are mainly used to encourage cross flow ventilation within a room, usually where the aspect is too deep for openable windows or other wall openings to work efficiently. Designed for façade installation. Comprised of an external aluminium louvre, a volume control damper and an internal grille. Acoustic air transfer system An internal wall mounted system that promotes cross flow ventilation within rooms to reduce heat build-up. Roof Mounted Terminal With similar external appearance to the Windcatcher Classic, the internal configuration has no internal dividers...

WINDCATCHERX-AIR Monodraught’s patented Activlouvre® modulating aerofoil louvre technology combines a static external louvre and a modulating internal louvre. They work together to vary the opening and free area. Maximum ventilation rates are achieved when the louvres are fully open. Weather resistance is increased when they are partially modulated. Alternatively, they can be closed to prevent the ingress of precipitation. External air catchment fins provide greater area at the louvre which improves performance in relation to wind speed. Pressure release vanes at the fins reduce face...

WINDCATCHER X-AIR & SOLA-BOOST X-AIR OPERATION MODES Natural Ventilation External temp >15°C and internal temp >21°C or CO2 >1000ppm The X-Air Thermal Mixing Unit can provide natural ventilation through the buoyancy of the internal air and wind pressures exerted upon the system at roof level. Warm air is extracted through the leeward side of the system due to the negative pressure upon the roof terminal. Fresh air is entrained in the windward side. Boost Fan External temp >15°C and internal temp >26°C or CO2 >1400ppm The X-Air Thermal Mixing unit can supply boosted ventilation during...

WINDCATCHER HX Our latest natural ventilation product provides exceptional comfort and energy consumption through a range of optimised heat recovery modes. The new Windcatcher HX provides natural ventilation with heat recovery technology using an integrated counterflow heat exchanger (HX) and a robust intelligent control strategy. The adaptive controls sense air quality in real time and seamlessly switch between energy efficient modes: natural, mechanical, and heat recovery ventilation. The 60W solar PV panels run boost ventilation fans, and even during very low wind speed periods,...

Natural Ventilation The Windcatcher system encapsulates the prevailing wind, and turns that wind movement through 90° in to the space. Fresh air is brought into the room and stale air is expelled using the negative pressure on the leeward side of the Windcatcher as well as the buoyancy and stack effect of warmer air rising within the space. Boost Fan Utilising the PV panels the Windcatcher HX can provide a boosted ventilation rate without the use of grid power. This ensures that even when there are periods of very low wind speed the ventilation rates required are met. Heat Recovery To avoid...
