Katowice Business Centre is a modern office building where Danfoss hydronic balancing solutions are used; AB-QM™ balancing and control valves in combination with revolutionary NovoCon® actuators.

The Prime Tower in Zurich is a building of many records. With its 126 meters it is the tallest building in Switzerland with 36 floors and 40,000 square meters accommodating mostly offices. And with its more than 6,000 AB-QM valves it is also one of the biggest heating and cooling installations ever designed and installed by Danfoss.

The tallest building of the EU now resides in Wroclaw in Poland. As a beautiful landmark to modern architecture, high user comfort and sustainable practice, the 212 meter high Sky Tower forms the pleasant setting for thousands of people living and working in the building.

Building: Hotel
Application: Hydronic balancing and control of water-based cooling system
Challenge: Proof effectiveness of PIBCV valves
Solution: Comparison test with Hydronic analyzer between traditional and PIBCV balancing and control options

In recent years, average rent for a one-bedroom apartment in Brooklyn’s Bushwick neighborhood has skyrocketed to more than $3,000 a month, excluding utilities. That’s why New York City’s Department of Housing Preservation and Development (HPD) and Ridgewood Bushwick Senior Citizens Council (RBSCC) came together to develop Knickerbocker Commons.

Department of Conservation and Natural Resources conscientiously chooses low-energy, high-comfort solutions to heat the new Resource Management Center in Pennsylvania’s Buchanan State Forest district. Discover how Danfoss ESBE valves and actuators efficiently controlled the hydronic heating system.

600 residents in the town of Soma in Western Turkey now enjoy the comforts of a reliable and cheap heat supply from the town’s brand new district heating system. 

In the coming years, more than 8,000 households will be joining the system that exploits the excess heat from the municipal power plant – a great improvement from the charcoal boilers of the past, and much less expensive.

The Interchurch Center, located in New York City’s Upper West Side, serves as headquarters for a number of nonprofit organizations.

“Between the induction units and the windows, my water temperature was reduced by 10 degrees in the heating season. That’s a significant change, and definitely one that is saving us money.”

Discover how the Danfoss hydronic heating solution provided a comfortable, efficient & affordable induction system upgrade.

The city of New York, undertakes an impressive effort to prepare the city for one million more residents, strengthen its economy, combat climate change and enhance the quality of life for all New Yorkers. 

Results of study show potential annual energy savings of ~$100 million if TRVs were installed in every NYC multifamily building.

Creating a sustainable energy system to heat, cool and power an entire college campus is no easy feat. In 2013, when Sheridan College launched its Energy and Climate Master Plan, with the goal of lowering campus energy and greenhouse gas emissions by half, they realized that they would need to transform their heating and cooling system. They looked to the Trias Energetica model, first developed in 1979, as a guide to developing a sustainable energy system, integrating heating and cooling functions and recovering energy that might otherwise be wasted.

A major renovation project in Aff aldVarme Aarhus (AVA), in collaboration with the Danfoss-owned company Sondex®, has increased the efficiency of the heat exchangers by more than 20 percent by replacing old plates with new ones.
