Monodraught Natural Ventilation

Product catalog summary
Introduction
Monodraught, founded in 1974, specializes in innovative and sustainable Natural Ventilation systems. These systems are rigorously tested to ensure optimal building ventilation performance.
Natural Ventilation
Natural Ventilation systems provide continuous fresh air supply, enhancing indoor air quality by eliminating fan noise and reducing energy costs. They are designed to be maintenance-free and sustainable, utilizing wind pressure and thermal buoyancy.
No Leak Guarantee - X-Air Systems
The WINDCATCHER X-AIR system offers a 10-year No Leak Guarantee, featuring advanced weather protection with patented louvre technology and a profiled internal rain trap louvre.
WINDCATCHER Classic
The WINDCATCHER Classic is an energy-free system combining top-down and passive stack ventilation, effective regardless of wind direction, suitable for environments like schools and healthcare facilities.
Operation Modes
  • Summer: Uses perimeter windows for cross-flow ventilation, enhancing the passive stack effect.
  • Night Time and Mid-Season: Operates independently of open windows, providing cooling and security.
  • Winter: Maintains ventilation rates to match occupant needs, minimizing heat loss.
Control and Acoustics
The iNVent 2 system manages ventilation across multiple zones using temperature and CO2 sensors. Acoustic performance is enhanced with insulation foam, significantly reducing noise transmission.
Projects
Monodraught systems have been successfully implemented in projects like Royal Chelsea Hospital, St Joseph’s College, and Imperial College, demonstrating their effectiveness in diverse settings.
Conclusion
Monodraught's Natural Ventilation systems offer reliable, energy-efficient solutions for building ventilation, backed by extensive testing and a strong performance track record.
WINDCATCHER X-AIR System
The WINDCATCHER X-AIR is an advanced system capturing wind from any direction and using the stack effect to circulate air. Key features include a composite upstand, swept divider, ActivLouvre Technology, and solar-powered lighting.
Applications and Case Studies
The WINDCATCHER X-AIR has been implemented in projects like Tesco's Eco-Stores and Craig Tara Holiday Park, maintaining comfortable temperatures and acceptable CO2 levels.
SOLA-BOOST Classic System
The SOLA-BOOST Classic enhances the WINDCATCHER design with a solar-powered fan for increased ventilation on sunny days, operating without energy costs.
SOLA-BOOST X-AIR
The SOLA-BOOST X-AIR features ActivLouvre technology and a solar-powered fan, integrating with WINDCATCHER X-AIR systems for additional ventilation without energy costs.
VENTSAIR Systems
VENTSAIR systems include roof-mounted terminals, acoustic air transfer systems, and façade ventilation systems, designed for areas with low occupancy or where cross ventilation is needed, maximizing airflow while minimizing sound transfer.
Conclusion
Monodraught's natural ventilation systems effectively meet design criteria for fresh air and temperature control, providing energy-efficient solutions for various building types.

Natural Ventilation “Monodraught WINDCATCHER® systems have proved to be the most effective method Why Choose Natural Ventilation? of providing Natural Ventilation to any commercial building.” Sustainable Energy in Action Healthier Natural Ventilation brings a steady supply of fresh air into the building, topping up the oxygen level, whilst at the same time expelling stale air to the atmosphere using the natural buoyancy of thermal forces. Fan noise, often associated with mechanical systems or air conditioning, is eliminated, to the benefit of the occupants. By maximising the use of wind pressure...

WINDCATCHER Classic Night Time and Mid-Season Operation What is WINDCATCHER Classic? During mid-seasons, in the evenings, or at weekends, when the building is perhaps unoccupied, the WINDCATCHER system is not dependent on openable windows or vents in the side of the building, which allows the building to fully secure. The WINDCATCHER is an energy free Natural Ventilation system encompassing the benefits of both top-down and passive stack ventilation. The system consists of four external louvre banks, to stop the ingress of precipitation, which are protected internally by TriLayer weather protection....

WINDCATCHER Classic Projects Royal Chelsea Hospital London Monodraught WINDCATCHER Natural Ventilation systems were selected to provide energy-free fresh air throughout the new three storey flagship care home. The fifteen systems were cleverly adapted by Monodraught to complement the architectural style of the new infirmary, which is in context with original Wren and Soane buildings. The units were clad in clay pantiles to ensure a perfect blend with the architectural style. CFD analysis was carried out using Monodraught’s own development team and then verified using external specialists to optimise...
