Daikin adds heat recovery to Compact series AHU
17th December 2025
ITALY: Daikin is expanding its Compact series air handling unit portfolio with the addition of a new model that includes rotary heat recovery in the same footprint.
The new Compact R is said to incorporate installation-oriented improvements and enhanced flexibility. Available in seven sizes covering airflow rates from 500 to 6,000 m³/h. It is offered in right- or left-hand configurations, with side connections that simplify integration into different plant layouts.
Thanks to its compact dimensions, the unit can be installed indoors or outdoors, providing a flexible solution for both new projects and refurbishments.
To adapt to diverse project needs, Compact R can be equipped with a broad selection of accessories, including electric heaters, heating coils for pre- or post-treatment, additional filtration stages and sound attenuators.
The AHU is fully compatible with the Daikin AHU-DX kit, creating a single integrated system that combines the AHU and condensing unit under one control platform. Daikin maintains that this minimises wiring, improves commissioning efficiency and ensures optimal performance. The main treatment coil – available as a water or DX coil – is integrated directly in the module, preserving the compact footprint.
Compact R can also be combined with Daikin VRV R32 systems for highly efficient heating and cooling, supported by built-in safety devices for R32.
A rotary heat recovery wheel – available in condensation or sorption versions – allows Compact R to recover both sensible and latent heat.
The filtration system includes an ePM1 50% (F7) filter on the supply air and an ePM10 75% (M5) filter on the return air.
Eurovent certified, the Compact R is produced following a make-to-stock approach, ensuring short lead times. Larger sizes are delivered in two separate modules to facilitate handling in confined spaces, especially during renovations. While the unit is configured for indoor installation by default, an outdoor kit is available for full installation flexibility.
As a decentralised ventilation solution, Compact R enables zone-by-zone control and quick installation. Integration with the Daikin IEQ sensor allows monitoring of indoor air quality and enables demand controlled ventilation, adjusting fan speed and ventilation rates according to real IAQ needs.
Compact R is also compatible with Daikin on Site (DoS), Daikin’s 24/7 remote monitoring platform.
