Large commercial buildings present unique challenges when it comes to heating, cooling and ventilation. Warehouses, factories, distribution centres, retail parks, sports facilities and manufacturing plants often require significant air volumes, high energy efficiency and reliable year-round climate control. Traditional split systems can become complex and costly on larger projects, which is why rooftop packaged units continue to be one of the most popular HVAC solutions for commercial and industrial environments.
The Daikin UATYA Rooftop Packaged Heat Pump range has been developed specifically to meet these demands. Combining heating, cooling, ventilation and advanced controls within a single factory-assembled package, these systems offer a highly efficient and practical solution for large open-plan spaces. Designed around environmentally responsible R32 refrigerant, inverter technology and Daikin's proven commercial HVAC expertise, the UATYA range provides a complete climate control solution from a single rooftop installation.
What Is a Rooftop Packaged Unit?:
A rooftop packaged unit combines all major HVAC components into a single self-contained system. Unlike conventional split systems that require separate indoor and outdoor units connected by extensive pipework, a rooftop packaged unit houses compressors, heat exchangers, fans, controls and refrigeration components within one factory-built assembly.
This "plug and play" approach significantly simplifies installation. Because the refrigeration circuit is pre-charged and factory tested, there is no requirement for additional refrigerant pipework between indoor and outdoor sections. The unit is positioned on the roof and connected directly to the building's ductwork system, allowing conditioned air to be distributed throughout the occupied space.
Why Businesses Choose Rooftop Systems:
For many commercial buildings, rooftop units offer significant advantages over alternative HVAC technologies. By locating the equipment on the roof, valuable internal floor space remains available for operational use. This is particularly important within warehouses, manufacturing facilities and retail environments where every square metre of floor space has commercial value.
The packaged design also simplifies installation, commissioning and maintenance. All major components are contained within a single enclosure, making servicing more straightforward whilst reducing the complexity associated with large multi-unit systems. Daikin's rooftop units are specifically designed for high installation flexibility and easy servicing, helping reduce downtime and ongoing maintenance costs.
Advanced R32 Heat Pump Technology:
One of the key features of the Daikin UATYA range is the use of R32 refrigerant.
R32 offers a significantly lower Global Warming Potential (GWP) than many older refrigerants whilst delivering excellent energy efficiency. Daikin has invested heavily in R32 technology across its commercial product range as part of its ongoing commitment to reducing environmental impact and improving system performance.
The UATYA series combines this refrigerant with highly efficient heat pump operation, allowing the system to provide both heating and cooling from a single unit. This makes the range particularly attractive for buildings requiring year-round temperature control whilst seeking to reduce energy consumption and carbon emissions.
Built for Large Commercial and Industrial Spaces:
The Daikin UATYA range has been specifically designed for larger applications where airflow requirements and cooling loads are substantial. Available in capacities ranging from approximately 25kW up to 190kW, the range can accommodate a vast variety of commercial environments. The use of high-efficiency scroll compressors and advanced EC fan technology helps ensure reliable performance even under demanding operating conditions. Daikin also offers external static pressure capabilities of up to 800Pa, allowing air to be distributed effectively through extensive ductwork systems serving large buildings.
This makes the UATYA series particularly suitable for projects where long duct runs and large air volumes are required.
Integrated Ventilation and Free Cooling:
Modern commercial buildings increasingly require fresh air ventilation alongside heating and cooling. Selected UATYA models incorporate integrated fresh air dampers and free cooling functionality. During suitable outdoor conditions, the system can utilise cooler external air to help condition the building without relying solely on mechanical cooling. This can significantly reduce energy consumption whilst improving indoor air quality.
More advanced versions within the range offer integrated extraction dampers, thermodynamic heat recovery and high-efficiency plate heat exchangers capable of recovering up to 58% of waste heat from extracted air. These features further improve energy performance whilst helping buildings comply with increasingly demanding efficiency requirements.
Smart Building Integration:
Building management systems have become a vital part of modern commercial facilities.
The Daikin UATYA range features advanced pCO5 controls and supports direct integration with Daikin Building Management Systems as well as third-party BMS platforms through BACnet and Modbus communication protocols. This allows facility managers to monitor and control HVAC performance centrally whilst optimising energy usage and operational efficiency.
Integrated touchscreen controls, intelligent diagnostics and advanced monitoring capabilities provide greater visibility of system operation and help simplify maintenance planning.
