The Compact line, now with rotary heat recovery — without sacrificing the footprint you've always worked with.
Until now, specifiers choosing a compact, side-connected AHU had to accept plate heat recovery. Compact R changes that. It brings a high-efficiency heat wheel — in condensation or sorption versions — into the same space-efficient casing the Compact series is known for. The result is a unit that recovers both sensible and latent energy, adapts to a wider range of climate conditions, and installs exactly where you need it: indoors or outdoors, in new builds or refurbishments.
7 pre-configured sizes
From 600 to 5,000 m³/h nominal airflow — up to 6,000 m³/h maximum — covering the full range of light commercial ventilation needs in a single product family.
2 heat wheel technologies
Condensation wheel for sensible heat recovery in standard applications; sorption wheel for full enthalpy recovery where humidity management is a priority.
1 integrated system
Cooling and heating coils — water or DX — fit inside the same compact casing. One unit, one connection point, one commissioning process. Delivered plug-and-play from stock.
Built for performance, designed for flexibility
Compact R combines rotary heat recovery, EC fan technology and a space-optimised casing to deliver efficient ventilation across a wide range of commercial applications.
Rotary Heat Recovery
High-efficiency heat wheel in condensation or sorption versions recovers both sensible and latent heat, reducing energy consumption year-round while stabilising indoor conditions.
Compact, Space-Efficient Casing
Seven pre-configured sizes spanning 600–5,000 m³/h nominal airflow (up to 6,000 m³/h maximum). Side duct connections simplify integration into any plant layout.
Indoor & Outdoor Installation
Designed for indoor use as standard, with an available outdoor kit for full siting flexibility. Suitable for new builds and refurbishment projects alike.
EC Fan Technology
Electronically commutated fans deliver precise airflow control with low energy consumption, supporting variable air volume and constant air volume operation strategies.
DX & Water Coil Integration
Cooling and heating coils — water or DX — are integrated directly within the unit module. Compatible with Daikin AHU-DX kit for R-32 and R-410A systems, including VRV.
Plug & Play, Make-to-Stock
Pre-configured and factory-tested with pre-set controls. Larger sizes ship in two modules for handling in confined spaces. Short lead times from stock production.
The right solution for every space
From retail to education, Compact R adapts to the ventilation demands of diverse commercial environments, delivering healthy, comfortable air where it matters most.
Offices
Support occupant productivity with stable, controlled indoor air quality across open-plan and cellular spaces.
Education
High-quality filtration and DCV capability ensure healthy learning environments that adapt to room occupancy.
Retail
Compact footprint suits tight plant rooms; flexible configurations handle varying occupancy loads.
Hospitality
Indoor or rooftop installation options and quiet, efficient operation make Compact R ideal for hotels and restaurants.
Heating and cooling without the gas boiler
Compact R is designed for the buildings of today and the regulations of tomorrow. Its integrated DX capability and low-GWP refrigerant compatibility make it a direct enabler of fossil-free HVAC systems.
Eliminates the need for gas boilers
The Daikin AHU-DX kit integrates a condensing unit directly with Compact R, enabling both heating and cooling without any gas infrastructure — reducing scope 1 emissions on day one.
R-32 and R-410A compatible
R-32 delivers the same performance as R-410A at roughly one third of the GWP — significantly reducing the environmental impact of the refrigerant charge over the unit's lifetime.
VRV R-32 system integration
Compact R connects seamlessly to Daikin VRV R-32 multi-zone systems, creating a single, highly efficient platform for heating, cooling and ventilation across the building.
BREEAM & LEED contribution
Energy-efficient ventilation with heat recovery and low-GWP refrigerants contributes directly to green building certification credits under BREEAM, LEED and WELL programmes.
High-GWP refrigerants are being phased out
The time to design for low-carbon HVAC is now. The revised EU F-Gas Regulation is accelerating the transition away from high-GWP refrigerants across all HVAC equipment categories. Compact R is designed with this transition in mind — supporting R-32 natively, compatible with the Daikin AHU-DX ecosystem, and ready to integrate into all-electric building systems that meet both current ErP requirements and anticipated future standards.
Intelligent management, seamless integration
Control & Connectivity: Compact R is built around Daikin's open Pro control platform, fully compatible with the Daikin ecosystem and any modern Building Management System.
Pro Open Platform
Daikin's open control platform supports BACnet and Modbus protocols for full interoperability with any BMS. Pre-configured at the factory for faster on-site commissioning.
Daikin on Site (DoS)
24/7 remote monitoring via Daikin's cloud platform. Real-time performance data, alarm notifications, and trend analysis reduce downtime and support proactive maintenance.
IEQ Sensor & DCV
Integration with the Daikin IEQ Sensor enables Demand Controlled Ventilation — automatically adjusting fan speed based on real indoor air quality readings, saving energy where occupancy is variable.
AHU-DX Kit (VRV Compatible)
Plug-and-play integration with Daikin VRV R-32 systems using the AHU-DX kit. Supports both R-32 and R-410A for flexible, low-GWP system design without gas boilers.
Smart Control System (SCS)
Compatible with Daikin's Smart Control System for integrated hydronic plant management — coordinating chillers, heat pumps, AHUs and fan coils under one platform.
