Designed for a wide range of applications, from restaurants and offices to schools, gyms, and large hotels, the ZEPHIR4 series offers air flow rates from 2,300 to 19,000 m³/h. It builds on the innovation introduced with the original ZEPHIR model in 2004, now enhanced to deliver higher operating efficiencies year-round.
“The main benefit of ZEPHIR4 is its versatility: it is the ideal solution for both the renovation of existing buildings and new constructions,” said Damiano Rossi, Product Manager at Clivet.
ZEPHIR4 uses heat pump technology to recover energy from exhaust air and transfer it to incoming fresh air, amplifying the effect via its refrigeration circuit. This process neutralises the thermal load of outdoor air and contributes to meeting internal building demands—regardless of season.
The system is classified as T2/TB2 under UNI EN 1886, ensuring high thermal and mechanical performance. It guarantees comfortable air intake even at outdoor temperatures as low as -20°C and offers an extended operating range in cooling mode.
Efficiency, Filtration, and Smart Control
Key features of ZEPHIR4 include:
- Full inverter operation with high-efficiency energy recovery
- Low ventilation absorption and reduced energy consumption
- Latest-generation iFD electronic filters and CO2 monitoring
- Precise temperature and humidity control in heating and cooling modes
- Free modulating post-heating and additional room conditioning capacity
- No contamination between exhaust and intake air
- Intelligent free cooling and ambient air quality management
- All components mounted onboard for simplified design
- Compatibility with Clivet VRF centralisers and supervision systems like CLIVET EYE and INTELLIAIR.
Thanks to its independence from other HVAC systems, ZEPHIR4 offers significant savings in both initial investment and daily operation. Its benefits extend across the supply chain—from designers and investors to installers and end users.
