Daikin Expands Large-Space HVAC Portfolio with New Ranges

Daikin has expanded its offering for large-space heating and cooling applications with the launch of the Daikin Vertical Water and the new Daikin Space Cooler & Heater range. Engineered to address the diverse operational and installation challenges of warehouses, logistics centers, manufacturing facilities, and sports venues, both product lines are available in Direct Expansion (DX) and Hydronic versions. This dual-technology approach provides consultants, contractors, and building owners with the flexibility to select the most suitable solution for new builds, system extensions, or refurbishment projects, depending on existing building infrastructure. Both product ranges will be available starting in November 2026.

The new Daikin Vertical Water builds upon the company's floor-standing design, expanding its application into hydronic systems. The unit is optimized for spaces where ceiling installation is impractical or where rapid deployment and minimal operational disruption are critical. The floor-mounted design simplifies integration, while features like Plug & Play configuration, reversible left- or right-side connections, and standard ductless operation expedite installation. For facilities prioritizing usable floor space, the wall- or ceiling-mounted Daikin Space Cooler & Heater ensures effective air distribution even in high-ceiling environments. The Space Cooler & Heater range is offered in Nozzle, Grille, and Premium Self-Adjusting Nozzle configurations to precisely meet optimized comfort and air distribution requirements.

The expansion of e-commerce and automated logistics has led to a surge in massive, high-ceiling distribution centers where maintaining uniform temperatures is notoriously difficult due to thermal stratification. The Daikin Space Cooler & Heater addresses this by utilizing specialized nozzles, particularly the Premium Self-Adjusting Nozzle, which dynamically modulates airflow based on the temperature differential to throw conditioned air effectively to the floor level without requiring extensive ductwork networks.

The decision between Direct Expansion (DX) and Hydronic (water-based) systems is a fundamental architectural choice. DX systems—which circulate refrigerant directly to the indoor units—are highly efficient and ideal for new builds or extensions where a Variable Refrigerant Volume (VRV) network is already present. However, for massive industrial complexes or deep retrofits, pumping refrigerant over very long distances can lead to pressure drops and requires significant refrigerant volumes. In these scenarios, Hydronic systems become advantageous. By utilizing water as the heat transfer medium, Hydronic units like the new Vertical Water can integrate seamlessly into existing chiller or boiler loops, offering a scalable, environmentally robust solution that simplifies compliance with stringent refrigerant regulations while leveraging existing plant investments. All units are manufactured at Daikin Applied Europe's facility in Caleppio di Settala, Italy.
