Daikin has broadened its Compact range with the introduction of the new Compact R air handling unit. The solution integrates a rotary wheel heat recovery system into an included, exceptionally space-saving casing, improving overall energy performance. Designed for commercial applications in modern buildings, the Compact R offers side duct connections for greater flexibility, simplified installation and an enhanced selection of configurations to meet contemporary AHU requirements.
A versatile solution for modern commercial buildings
Compact R is available in seven sizes covering airflow rates from 500 to 6,000 m³/h, making it suitable for a wide range of environments such as shops, offices and educational facilities. The units are 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 builds and refurbishments. Efficient airflow management helps improve Indoor Air Quality (IAQ) across various settings.
Flexibility through accessories and configuration
Whether for project requirements in retail, hospitality, office buildings or schools, Compact R can be equipped with a wide range of accessories – including cooling and heating coils, electric heaters for pre- or post-treatment, additional filtration stages and sound attenuators. This allows the system to be configured to meet the performance and comfort needs of a wide variety of applications.
Integration with Daikin technology
Compact R is fully compatible with the Daikin AHU-DX1) kit, creating a single integrated system that combines the air handling unit and the condensing unit under one control platform. This minimizes wiring, improves commissioning efficiency and ensures optimal performance. The main coil – available as water or DX coil – is integrated directly inside the unit, preserving the compact footprint.
Efficient energy recovery
A rotary heat recovery wheel – available in condensation or sorption versions – allows Compact R to recover both sensible (temperature) and latent heat (humidity). By recovering energy from the return air to the incoming fresh air, the unit reduces overall energy consumption while maintaining stable indoor conditions resulting in better indoor air quality throughout the year.
Reliable operation with reduced maintenance
The filtration system includes an ePM1 50% (F7) filter on the supply air and an ePM10 75% (M5) filter on the return air as standard. This ensures high-quality indoor air while protecting internal components from dust accumulation. Combined with Daikin engineering and the compact layout, this results in a reliable, low-maintenance solution.
Fast availability and simplified installation
Compact R is produced following a Make-to-Stock (MTS) 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. Compact R is delivered plug-and-play, with pre-configured factory settings to streamline installation and easy commissioning.
Smart control and performance monitoring
As a decentralized ventilation solution, Compact R enables zone-by-zone control and quick installation. Integration with the Daikin Indoor Environment Quality (IEQ) sensor allows monitoring of indoor air quality and enables Demand Controlled Ventilation (DCV), adjusting fan speed and ventilation rates according to real indoor air quality needs.
Compact R is also compatible with Daikin on Site (DoS), Daikin’s 24/7 remote monitoring platform. DoS improves system reliability, reduces downtime, and provides continuous performance insights.
