Zehnder ComfoClime Q: a single solution for all thermal comfort

As heat waves intensify and thermal regulations become more stringent, ensuring indoor comfort while optimizing energy efficiency is becoming a major challenge for building professionals. Zehnder is meeting this challenge with the ComfoClime Q , an innovation that combines heating, cooling, and ventilation in a single compact system. Combined with the ComfoAir Q 450 dual-flow ventilation system , this solution is a strategic asset for installers, project managers, and specifiers.

A compact monobloc system, without an external unit

The true strength of the ComfoClime Q lies in its ease of integration . No outdoor unit, no complex refrigeration network. This reversible air-to-air heat pump module installs directly above the ComfoAir Q 450 unit, thus minimizing its footprint (only 1950 mm high). It delivers 100% air comfort year-round, without any interruption in airflow or unnecessary equipment.

Key technical features:

• Airflow: up to 450 m³ / h
• Active Refresh: up to 2,7 kW (or 4,1 kW with enthalpy exchanger)
• Active heating: up to 2,9 kW (or 5,5 kW combined)
• Refrigerant: R32, with low environmental impact
• Technology Inverter for intelligent modulation

“Innovation is about keeping things simple when the technology is complex.” — An installer during the presentation at ARTIBAT

Smart control with Climate Switch®

Thanks to Climate Switch® technology , the ComfoClime Q automatically adapts its operating mode according to:

• The measured indoor temperature
• External climatic conditions
• The occupant's lifestyle (Comfort or Eco)
• The chosen time schedule

This intelligent control system ensures a consistent and controlled temperature in living areas, with controlled energy consumption.

Optimal air quality, summer and winter

Zehnder doesn't just offer good thermal comfort. The Swiss company also places indoor air quality (IAQ) at the heart of its concerns. The ComfoAir Q 450 + ComfoClime Q duo ensures:

• Continuous extraction of stale air (kitchen, bathroom, toilet)
• The insufflation of air new, filtered and tempered
• High-performance filtration against pollen, dust and VOCs
• A functioning, an operation, a operating, a working silent, suitable for collective housing and individual houses

A solution designed for professionals

Installation and maintenance have been simplified. The system comes ready to install, with intuitive interfaces and quick setup via the Zehnder ComfoClime app (Android/iOS). A local Wi-Fi connection enables seamless management, without the need for an additional gateway or cloud dependency.

Benefits for installers:

• No outdoor unit required
• Time saving during installation
• Easy integration in new builds and renovations
• Quick setup via smartphone or tablet

A response to regulatory and environmental challenges

By anticipating the requirements of the RE2020 regulation and European climate ambitions, Zehnder offers a solution that is both sustainable and high-performing. The use of R32 refrigerant , combined with moderate energy consumption thanks to the inverter, reduces the installation's carbon footprint.

In terms of certifications, the ComfoAir Q 450 is:

• NF205
• PassivHaus Institute
• Compatible with very high energy performance buildings

ARTIBAT 2025: a showcase for innovation

The ComfoClime Q will be presented at the ARTIBAT trade fair in Rennes from October 22nd to 24th (Hall 7 – Stand B27). This will be an opportunity for specifiers, installers, and architects to discover this 3-in-1 solution in operation.
