Introducing the Climtec Quattro 125: Intelligent Heat Recovery Ventilation with a Natural Touch
The Climtec Quattro 125 is a cutting-edge decentralised mechanical ventilation with heat recovery (dMVHR) system, perfect for UK homeowners prioritising both smart technology and sustainable design. Its distinctive square form factor and eco-friendly wooden inner shell offer a modern aesthetic without compromising performance. This smart ventilation system includes advanced humidity and CO₂ sensors, enabling automatic adjustment of airflow for optimal air quality and energy savings. With a flow rate of up to 60 m³/h and an impressive heat recovery efficiency of up to 93%, the Quattro 125 ensures a constant supply of fresh, clean air, making it an excellent home ERV system.
Key Benefits of the Climtec Quattro 125:
- Eco-Friendly Wooden Interior: A unique natural material for internal components (excluding front cover) reflects a commitment to sustainability.
Advanced Smart Sensors: Integrated humidity and CO₂ ventilation system control for automatic and precise air quality management.
Quiet Operation: Designed for exceptionally low noise levels, ensuring undisturbed comfort – a top quiet MVHR unit.
Modern Square Design: A sleek, contemporary aesthetic that seamlessly integrates into modern interiors, ideal for wall mounted heat recovery units.
Twin-Fan System: Guarantees continuous, balanced fresh air supply and stale air extract.
Durable Aluminium Heat Exchanger: Efficient and robust for reliable heat recovery ventilation.
Eliminates Mould & Dampness: Prevents moisture build-up for a healthier environment.
Optimal Heat Recovery Efficiency: Achieves up to 93% heat recovery, significantly reducing heating bills.
Low Energy Consumption: Efficient operation for minimal running costs.
Optional Activated Carbon Filter: For superior air purification and removal of odours.
How it Works: The Climtec Quattro 125 actively monitors indoor air quality using its integrated humidity and CO₂ sensors. When levels rise, the automatic ventilation system adjusts its powerful twin-fan operation, facilitating continuous air exchange through its efficient aluminium heat exchanger. This process ensures up to 93% heat recovery while delivering fresh, filtered air, making it a truly smart air vent.
