Suitable for new build multi dwellings; houses, flats or apartments, usually in dwellings that are classed as ‘highly airtight dwellings’ in Part F.

Range of mechanical ventilation with heat recovery (MVHR) units that work by combining supply and extract air.

Moisture-laden, stale air is extracted from wet areas, such as kitchens and bathrooms. The heat from the extract air is recovered by the heat exchanger in the MVHR unit and is recycled by warming up the supply air entering a dwelling.

Features and benefits:

• All models perform to Energy Savings Trust Best Practice levels.
• Controlled airflows.
• Pre-heated incoming fresh air.
• Heat exchange may reduce heat demand.
• May be useful where external noise pollution is a problem as there are fewer building penetrations.
• Low Specific fan power to 0.38 W/L/s.
• Airflow up to 158 L/s (568 m³/h).
• Heat recovery rates up to 91%.
• Award winning Trimbox NO₂ filter options.
• Four configurable speed options.
• Full thermal summer bypass.
• Offers an extensive range of controls.
• Sensors available: humidity, CO₂, temperature and air quality.
• Zintec sheet steel or expanded polypropylene casings.
• Independently Acoustically tested to BS EN 13141-7 (Induct measurements).
• Silencer attenuators available to assist in noise control.
• Enthalpy option available.
