Introducing the Zehnder EVO: A flexible
and compact solution for modern,
sustainable homes.
The Zehnder EVO is a new generation of heat recovery ventilation unit, combining smart design, flexible installation and outstanding energy performance into one compact package, purpose-built for sustainable living.
Smart Design, Built for the Future
Manufactured from expanded polypropylene and galvanised steel, the Zehnder EVO unit is fully recyclable, helping reduce resource consumption and minimise environmental impact from the outset.
Its exceptionally slim profile and wide range of configuration options mean it can be used as a space-saving alternative and installed in many areas where a traditional MVHR units cannot.
Intelligent Design Features
Every detail of the EVO has been engineered with the installer and end-user in mind:
- Automatic summer bypass: maintains an optimal indoor climate all year round without manual adjustment.
- Adjustable connections: modular connectors allow quick and easy configuration to suit any air distribution layout.
- Vertical or horizontal installation: Can be installed in either wall or ceiling applications.
- Adjustable condensate drains: rotate through 180°, making them suitable for any installation type.
- Acoustic comfort: four anti-vibration mounts and optimised centrifugal fans ensure whisper-quiet operation.
- Quick and easy installation: intuitive and straightforward, saving time and effort on site.
The EVO range covers three airflow capacities to suit different property sizes:
- Zehnder EVO 2 — up to 200 m³/h
- Zehnder EVO 3 — up to 300 m³/h
- Zehnder EVO 4 — up to 400 m³/h
Easy Installation, Flexible Mounting
The EVO is designed to be installed in a variety of configurations - horizontally in a suspended ceiling or vertically on a wall, with two brackets that allow for easy positioning on both surfaces.
Its guide rail system features lockable guides on all sides, and the four silentblock (anti-vibration) hooks eliminate vibration while minimising noise throughout the home.
Connectivity is built in from the start. Turn your home into a Smart Home with the Zehnder EVO mobile app, or integrate it into your wider building management system via KNX or Modbus.
High Quality and Performance
The Zehnder EVO delivers where it matters most, energy performance:
- Up to 90% energy efficiency: achieved through a high-efficiency counter-flow heat recovery exchanger and effective cross-flow air circulation.
- Airtight connections: a double symmetrical joint ensures a perfect seal between the unit and the duct, preventing energy loss.
- Low energy consumption: high-performance fans and unique aerodynamic design significantly reduce running costs.
- Constant airflow: advanced technology with forward-curved centrifugal fan blades delivers consistent air quality with lower energy draw.
- Lower pressure, better airflow: the aerodynamic design improves air movement without increasing internal pressure.
The Zehnder EVO holds recognised industry accreditations and has been independently tested by the BRE (Building Research Establishment) to a high standard, providing assurance of design quality and long-term reliability.
The Full EVO Range at a Glance
All EVO units are highly efficient constant-flow ventilation units, available with either a standard Heat Recovery Ventilator (HRV) or an Enthalpy Recovery Ventilator (ERV), the latter adding moisture recovery alongside heat recovery.
Models with an electric pre-heater (EVO PR) provide comfort even in freezing conditions, with no interruptions to the air supply and no risk of the heat exchanger freezing.
Key specifications at a glance:
- EVO 2 depth: just 21 cm, ideal for tight ceiling voids
- EVO 3 & EVO 4 depth: 27 cm
- Horizontal or vertical installation, no tilt required
- Adjustable connections — 160 mm external diameter spigots for easy integration with Zehnder air distribution systems
- Control via wireless remote, building automation system, or mobile app
Smart Control Accessories
The Zehnder EVO ecosystem includes a range of wireless accessories to put control at your fingertips:
- EVO Sense: a smart wireless control device allowing selection of five different flow rates, daily/weekly scheduling, and automatic mode.
- EVO Switch: a simple wireless control unit with four operating modes and a filter replacement alarm indicator.
- EVO Humidity Sensor: monitors relative humidity and automatically adjusts ventilation flow rate to maintain optimal indoor air quality.
- CO₂ Sensor: monitors carbon dioxide levels and instructs the unit to adjust flow rate accordingly.
- EVO Connect ModBus: integrates the EVO into building management systems via the widely used Modbus RS485 protocol.
- EVO Connect KNX: connects EVO units to KNX-based building management systems.
