Daikin Applied (UK) has expanded its portfolio of R-290 (propane) chillers and heat pumps, offering a scalable solution for commercial, industrial and mission-critical HVAC applications.
The extended range spans capacities from 17 kW to 2,000 kW, enabling specifiers to apply ultra-low GWP refrigerant technology to both small and large hydronic systems.

R-290 (propane) refrigerant delivers near-zero global warming potential (GWP) and zero ozone depletion, supporting compliance with evolving environmental regulations and decarbonisation targets.

Scalable system design
The portfolio includes:
• Monobloc units (17–85 kW) for smaller commercial and distributed systems
• Modular heat pump systems (up to 2,000 kW) for large-scale plant applications

The modular approach enables phased capacity installation, simplified transport, and flexibility within constrained plantroom layouts.

Each unit incorporates inverter-driven compressors and EC fans, allowing continuous capacity modulation to improve seasonal efficiency under part-load conditions.

Integrated safety for R-290 applications
Given the flammability of R-290, systems are designed with multi-layered safety features, including:
• Continuous refrigerant leak detection
• ATEX-certified ventilation
• Acoustic and visual alarms
• Independent power supply for safety systems
• Automatic hydronic circuit isolation in the event of a leak
This integrated approach enables safe deployment of propane-based systems in commercial environments.

Optimised control for complex systems
For multi-unit installations, systems can be managed via:
• Built-in unit sequencing for modular arrays
• Daikin Intelligent Chiller Manager (iCM) for plant-level optimisation

This allows efficient load management and system resilience in applications such as healthcare, data centres and industrial facilities.

Supporting low-carbon HVAC design
By combining natural refrigerants with modular design and advanced controls, the expanded range provides a practical route for consultants and contractors to specify future-ready, low-carbon HVAC systems.
