Daikin Applied (UK) has introduced its Vertical DX air handling unit, a floor-standing, plug-and-play solution designed to deliver efficient ventilation and precise temperature control in large commercial and industrial environments.

Developed for applications such as logistics hubs, distribution centres, sports halls and multi-use venues, the unit addresses common challenges including high air volumes, variable occupancy and uneven air distribution.

Decentralised ventilation approach

The Vertical DX unit applies a decentralised strategy, delivering air treatment closer to occupied zones. This improves responsiveness, reduces system losses and enables more accurate control of indoor air quality (IAQ) and temperature.

Flexible installation for new build and retrofit

The floor-mounted design enables installation with minimal disruption, making it well-suited to refurbishment projects and space-constrained environments.
Key features include:
• Plug-and-play configuration with factory-installed DX kit
• Reduced or no ductwork requirement
• Multiple discharge options (front, side, top)
• Left- or right-hand connection flexibility

This approach reduces installation time, cost and complexity compared with traditional centralised systems.

Integrated DX technology

The system uses direct expansion (DX) technology, allowing refrigerant to circulate directly within the unit and eliminating the need for a secondary water circuit.
When integrated with Daikin VRV or ERA systems, this enables:
• Reduced energy losses
• Lower system footprint
• Efficient part-load performance

Scalable control and system integration

The unit supports advanced control strategies, including Daikin Z Control for multi-unit configurations, and can be integrated into building management systems (BMS) for centralised monitoring and control.

Supporting low-carbon HVAC strategies

Compatible with low-GWP refrigerants such as R-32, the Vertical DX unit supports decarbonisation objectives while enabling efficient upgrades without major infrastructure changes.
