Clivet updates Zephir4 air renewal series
3rd October 2025
ITALY: Clivet’s new generation of Zephir4 air renewal and purification units come with air flow rates from 2,300 to 19,000m³/h, full inverter technology and R32 refrigerant.
The Zephir4 system recovers energy from the exhaust air and transfers it to the fresh air, upgrading it through the refrigeration circuit.
Its high thermal and mechanical performance, classified as T2/TB2 according to UNI EN 1886, is said to provide comfortable air intake conditions even with outdoor temperatures as low as -20°C. It also offers an extended operating range in cooling mode.
Clivet product manager Damiano Rossi claims that the main benefit of Zephir4 is its versatility. “It is the ideal solution for both the renovation of existing buildings and new constructions,” he said.
The integrated iFD electronic filtration technology and continuous monitoring of indoor air quality allow only the necessary air to be introduced into the environment. This is claimed to achieve energy savings of up to 45% for ventilation compared to traditional solutions.
Cliver claims precise temperature and humidity control in heating and cooling modes, and free modulating post-heating. All components are mounted on board the machine and it provides compatibility with VRF and Clivet supervision systems.
