YEAR: 2025

MODEL: 6 x HCI-3000 (1st phase)

APPLICATION: Combined heating and cooling

CAPACITY: 18 MW -> 30 MW

HEAT SOURCE: Excess heat from data center

Case in Finland: Turning data center waste heat into district heating

Fenagy has partnered with Finnish contractor Caverion to supply six isobutane/propane heat pumps to a utility company providing district heating to a city in the north-east of Finland. These heat pumps will enable the recovery of excess heat from a nearby data center and supply it into the district heating network.

The district heating plant is located near a large data center, which operates year-round and continuously generates excess heat from server room cooling. Traditionally, this heat was removed using dry coolers and thus became waste heat. By connecting heat pumps to the existing cooling water circuit, the system can now both provide cooling and recover the excess heat for district heating. The old chillers will remain in place but will only be used as a backup when needed.

Data centers require cooling throughout the year, which makes them a stable and reliable heat source - an ideal match for heat pumps. In winter, the heat pumps recover waste heat for the city’s residents; in summer, excess heat is released via the existing dry coolers.

The heat pumps

The heat pumps are customised HCI-3000 units designed to provide both heating and cooling. Each heat pump has three compressors, two using isobutane as a refrigerant and one using propane.

The excess heat from the data center is around 30°C. The heat pumps raise this to approximately 85°C to meet district heating requirements. On the cold side, they provide 20°C water for server room cooling, independent of the return temperature from the district heating network, which in this case is about 50°C.

Both isobutane and propane are highly efficient refrigerants. They are natural, PFAS-free and have an extremely low global warming potential.

When the system is fully implemented, it can deliver more than 30 MW of heat.

Efficient heating and cooling system for industrial operations

Effective heating and cooling systems are essential for industries that aim to reduce energy consumption and improve operational performance. In industrial environments, such as production facilities and data centres, managing temperature control is critical not only for comfort but also for the optimal functioning of equipment. Without a reliable system, energy waste increases, leading to higher costs and a larger environmental footprint.

At Fenagy, we understand the unique challenges faced by industrial businesses. Our heating and cooling systems are specifically engineered to improve energy efficiency, reduce operational costs and emissions by repurposing heat generated from cooling in one combined solution. Whether you are in manufacturing, logistics, technology, or something else entirely, our systems can help you optimise temperature control and reduce waste.

Optimising energy use with industrial heating and cooling

Industrial environments, especially those handling sensitive processes or materials, require precise temperature regulation. Our industrial heating and cooling systems are designed to ensure that temperature and humidity levels are consistent, providing the ideal conditions for both operations and personnel. Hence, our solutions help businesses maintain a comfortable and functional working environment.

By incorporating industrial heat pumps into your operations, Fenagy’s heating and cooling systems provide sustainable, cost-effective solutions for industrial heating and cooling needs. Our technology helps companies minimise energy use while enhancing system reliability and operational performance.

Cooling and heating solutions for data centers

Data centers are among the most energy-intensive environments, requiring a constant balance of cooling and heating to maintain server performance and prevent overheating. Fenagy’s combined heating and cooling systems offer an ideal solution for these facilities, providing both precise temperature control and energy efficiency.

Energy efficiency for high-demand environments

Data centers often experience fluctuating cooling needs due to variations in load. Fenagy’s systems, particularly our combined systems, provide the flexibility to meet these dynamic demands while reducing energy costs. By repurposing the heat generated from the plethora of servers in data centers, our systems also lower the carbon footprint of data center operations, aligning with the growing demand for sustainable IT infrastructure.

Cooling of data centers is required all year round. This generates large amounts of excess heat, which makes a very stable heat source – an ideal match for heat pumps! So instead of releasing the excess heat into the air and let it go to waste, it can be recovered with heat pumps and delivered to a district heating network or be used for heating of large greenhouses or other industrial processes.

Reliable temperature control

Maintaining a stable temperature is crucial for data centers, where overheating can lead to costly equipment failures. Fenagy’s heating and cooling systems ensure that your data center stays within the optimal temperature range, keeping servers running smoothly and reducing the risk of downtime.
