in-vent passive

Naturally intelligent ventilation with passive heat recovery and cooling. In-vent passive is not just natural, it continuously adapts to how the building is being used, providing the right amount of fresh air and comfort exactly when needed. It is the most ecological and efficient ventilation system available.

façade integrated passive ventilation

Using the latest advances in patented Heat Pipe technology, in-vent passive is the only façade-integrated natural ventilation system that passively recovers heat from outgoing, stale air during the heating season. A pure natural ventilation system, in-vent passive does not recirculate contaminated air back into the building by “air mixing”; instead, it supplies 100% fresh air - ensuring best levels of comfort for the occupants.

In-vent passive is easily integrated into the building through the facade without the need for bulky and unsightly internal boxing or additional supports - all its innovative components are contained within a shallow, attractive box. With discreet looks and a variety of colours and finishes, in-vent passive will seamlessly blend into any building or interior design.

Once installed, in-vent passive immediately connects to the Ventive cloud - enabling remote commissioning, real-time monitoring of air quality, occupant comfort and system performance, as well as ongoing adaptation, updates and proactive maintenance. All of this is available as standard, with no need for connection to complex building management systems or on-site network access; making in-vent passive one of the most intelligent and advanced ventilation and comfort management systems in the UK.

The technical team at Ventive will model, specify and manufacture the system to suit each project individually, taking care of the system performance and operational setup. More importantly, since all systems are fully monitored following commissioning, optimised performance and user satisfaction is ensured, and if the requirements change during the life of the building the performance parameters can be updated remotely to suit.

Naturally intelligent ventilation in a cost effective package, neatly integrated into the façade. The system provides fresh air, continuously monitoring and adapting its performance to minimise heat loss and energy use. Ventive in-vent passive is available with or without heat recovery.
