HVAC and building climate systems

Reliable heat transfer solutions for modern buildings

HVAC systems rely on glycol‑based heat transfer fluids to ensure stable and efficient heating and cooling performance. These fluids play a critical role in maintaining consistent temperatures in chilled water circuits, air conditioning systems and building climate applications. Our solutions are designed to deliver reliable freeze protection, corrosion resistance and long-term system efficiency in commercial and industrial HVAC installations. Glycol concentration can be adjusted depending on system design and required temperature range.

The role of heat transfer fluids in HVAC systems

In building climate installations, heat transfer fluids circulate through heating and cooling circuits, transporting energy between heat sources, chillers, storage units and distribution systems. To perform effectively, these fluids must combine predictable thermal performance with stable flow properties.

At the same time, HVAC systems often contain mixed-metal components such as steel, copper and aluminum. Without proper fluid formulation, these components can be exposed to corrosion, scaling and freeze-related damage, impacting system reliability and maintenance costs.

Supporting long-Term system reliability

Rotterdam Energy Fluids develops glycol-based heat transfer fluids specifically formulated to support long-term HVAC system operation. Our solutions are designed to provide:

  • Reliable heat transfer across a wide temperature range
  • Consistent circulation and flow characteristics
  • Protection against freezing, corrosion and deposit formation
  • Chemical stability during continuous operation

This makes our fluids suitable for both new building projects and existing HVAC installations where system reliability and lifecycle performance are key priorities.
