The Inventer Duct-free Decentralised Ventilation System with Heat Recovery provides an effective solution for ensuring a healthy indoor environment without requiring intricate ductwork. This system enhances air quality, regulates humidity, and minimises the risks of condensation and mould, while maintaining warmth and promoting energy efficiency.
Ideal for airtight and windtight buildings, these systems ensure continuous airflow by supplying fresh, filtered air while expelling stale indoor air. Their decentralised design removes the requirement for extensive ductwork, making them ideal for retrofit projects or modern airtight constructions.
Equipped with advanced ceramic heat recovery cores, these systems transfer heat from outgoing air to incoming fresh air, helping to maintain comfortable indoor temperatures with minimal energy loss. Their ultra-quiet operation ensures comfort without disrupting your living or working environment. The filtration options, including pollen and activated carbon filters, remove dust, allergens, and pollutants, enhancing air quality and safeguarding health.
The system operates through synchronised pairs of fans that alternate airflow every 70 seconds. This cycle effectively stores and reuses heat. Customisable with intuitive controllers, and extendable with humidity sensors, and soundproofing inserts, these units adapt to various indoor environments.
Whether for a single room or an entire building, Inventer systems deliver sustainable, energy-efficient ventilation that supports healthier living spaces while protecting structures from humidity-related damage.
About Heat Recovery Ventilation
The Inventer system offers an energy-efficient solution for single-room or multi-room ventilation with heat recovery. Operating as a duct-free, decentralised system, it circulates fresh air while expelling stale air, ensuring optimal humidity and indoor air quality.
Each unit is equipped with a sophisticated ceramic heat exchanger that captures heat from outgoing air and transfers it to incoming fresh air. This minimises energy loss and maintains a comfortable interior environment. The decentralised design is ideal for retrofits and airtight buildings, offering flexibility and straightforward installation.
