Water / Hydronc Coils

Hydronic Coils

At HeatEX Technologies, we produce high-quality hydronic (water) coils known for their exceptional performance, longevity, and energy efficiency. These critical HVAC components help to heat or cool air in various systems, using a liquid-based method for temperature control.

What are Hydronic Coils?

Hydronic coils, also known as water coils, function as a medium for heat transfer in HVAC systems. They rely on the thermal properties of water or other heat transfer fluids to either heat or cool air. As warm or cold water circulates through the coils, air passing over the coils is heated or cooled down, enabling efficient temperature control.

Anatomy of a Hydronic Coil

Hydronic coils comprise a series of interconnected tubes, typically made of high-grade copper or stainless steel, which are surrounded by fins to enhance heat transfer. The coil configuration, tube diameter, and fin spacing are carefully selected to balance efficiency, pressure drop, and capacity. The liquid (hot water for heating, chilled water for cooling) circulates through the tubes, while air flows over the fins and tubes, enabling heat transfer.

Optimal Design for Maximum Efficiency

Our hydronic coils are precision-engineered for optimal performance. We strategically design the tubes and fins to maximize the surface area, allowing for superior heat transfer. The materials used in manufacturing our coils have been selected for their high thermal conductivity, durability, and corrosion resistance, providing reliable, long-lasting performance.

Applications of Hydronic Coils

Hydronic coils have wide-ranging applications across numerous sectors:


  • Commercial HVAC Systems: Hydronic coils are used in HVAC systems to regulate indoor air temperature, ensuring comfort in homes, offices, schools, and other buildings.
  • Process Cooling and Heating: In industrial settings, hydronic coils are employed to control temperatures in manufacturing processes, including food and beverage production, chemical processing, and other industries.
  • Air Handling Units (AHUs): AHUs often employ hydronic coils to regulate and circulate air throughout large commercial buildings or complexes.
  • Data Centers: Hydronic coils are used in cooling systems for data centers, helping to manage heat generated by servers and other equipment.
  • Radiant Floor Heating: In some radiant floor heating systems, hydronic coils are used to heat the water that circulates beneath the floor, providing comfortable and efficient heating.


Hydronic coils are versatile and customizable, catering to a wide variety of heating and cooling applications.
