Data Centre Cooling Solutions
Our team is dedicated to innovation, ensuring that cooling solutions, whatever the methodology, remain efficient, effective, and environmentally responsible.
Before Everything, Comes Cooling
Future-ready data centre cooling solutions designed to support AI growth, operational resilience, and long-term performance.
The Data Centre Cooling Challenge
We find ourselves in the midst of a technology revolution, driven by the race for smaller, faster, and more densely packed computing power. This rapid pace of innovation has transformed data centres into highly specialised environments, where cooling is no longer a one-size-fits-all solution.
As rack densities continue to rise and AI-driven workloads place unprecedented demands on infrastructure, effective cooling has become a critical factor in performance, resilience, and sustainability.
At the same time, the data centre industry is becoming too complex, too fast-moving, and too high-stakes for transactional vendor relationships. The future cannot be built reactively. It requires strategic partners capable of understanding the complete ecosystem and adapting alongside evolving technologies and business needs.

Hydro-DENCO® High Capacity CRAH
Hydro-DENCO® are Computer Room Air Handlers (CRAH) for cooling server rooms, medium size to hyper scale data centres, UPS or other technical rooms that have year-round air-cooling requirements. The reliable and proven devices offer extra high area-specific performance, high efficiency, and low energy consumption. They are appealing due to high-quality components such as EC fans, powerful heat exchangers and a modern control system.
Aria-DENCO® Fan Wall Unit
Multiple Configuration Fan Wall units, matching the exact requirement for your data Centres, Denco by FlaktGroup is able to bespoke design your AHU to the configuration that you need. We can design our units, from scratch each time, we have delivered 400 Aria-DENCO fan wall units across the globe since 2017 - 2021.
Close Control Multi-DENCO®
Multi-DENCO is the our most flexible product from the DENCO range. Whilst predominantly designed to address the needs of IT cooling, it is not limited to being used in workshops, computer rooms, telecom rooms, laboratories, libraries and even archives and museums. Its key is its superior ability to control both the temperature and humidity enabling you to have confidence that your operations are in the ideal climate.
Chiller, FGFC 2123 - 3180 BF2 (R-1234ze, 840 – 1800 kW)
The FläktGroup air-cooled chillers with free-cooling function of the FGFC 2123 - 3180 BF2 are tailored to the requirements of data centres. They are characterized by market-leading high technical standards and therefore best-in-class energy efficiency values.
- Refrigerant: HFO R1234ze – ultra-low GWP (<1), zero ozone depletion
- Compressors: Oil-free centrifugal with magnetic levitation
- Free Cooling: Integrated coils for hybrid and total free cooling
- Efficiency: Up to 20% annual energy savings with new control logic
- Water Temperature: Chilled water up to 26°C, ΔT up to 20 K
Ultra-DENCO®
The unit has been designed to meet the performance and efficiency needs of data centers, with large cooling capacity, large airflow, small energy consumption. Designed for only a down flow air configuration and chilled water cooling, the unit is ideally suited towards rooms which have a 500 mm floor void.
CAIRplus air handling unit
The CAIRplus product series is the premium range of air handling units and can satisfy practically every demand with a wide range of model sizes, installation types and configurations. All functions and unit arrangements required by HVAC standards are available regardless of commercial or industrial applications.
JMv® Aerofoil axial flow fan
The Woods JMv Aerofoil delivers aerodynamic efficiencies up to 84.8%, low SFPs and significant running cost and carbon emission reductions. Our JMv product is a fully cased axial flow fan which offers high-efficiency performance. Each impeller is manufactured from high-pressure die-cast aluminium, which is X-ray inspected using real-time radiography (in accordance with ASTM E-155) to ensure product integrity and quality. Impellers are precision balanced to minimize vibration levels and assure smooth operation.
