Our revolutionary oval tube technology dramatically reduces air-side pressure drop, allowing a smaller fan motor to achieve the same cooling capacity—resulting in a significant reduction in energy usage and costs. Ideal for high-performance systems in energy-conscious environments, this technology reflects our commitment to smarter coil design and long-term operational savings.
Coilmaster oval tube technology is engineered to improve coil performance by changing the geometry of the tube itself. Unlike traditional round tube designs, oval tubes present a more aerodynamic profile to the airflow passing across the coil. This reduces resistance as air moves through the coil surface.
By combining oval tube geometry with advanced fin surface design, Coilmaster creates a more efficient heat transfer path while minimizing airside restriction. In some applications, materials such as stainless-steel tube or stainless-steel elliptical tube may be used to support durability and corrosion resistance. The result is a coil design that delivers the required cooling capacity while reducing the load placed on system components.
Oval tubes allow air to move more smoothly across the coil surface compared to conventional round tube designs. The streamlined shape reduces turbulence and creates a more uniform airflow path through the coil.
This improvement leads to measurable reductions in airside pressure drop. Lower pressure drop means the system fan does not need to work as hard to move air through the coil. Designs using straight oval tubing help maintain consistent airflow while reducing resistance across the coil face.
In certain engineered systems, variations such as stainless-steel oval pipe or stainless-steel perforated tube may be incorporated where airflow distribution or structural requirements demand specific configurations. These design options support improved airflow performance without compromising system reliability.
Reducing airside pressure drop has a direct impact on system energy use. With less resistance across the coil, smaller fan motors can be used to achieve the same airflow and cooling capacity. This leads to lower fan energy consumption and reduces operating costs over time.
Coilmaster oval tube technology supports:
In many applications, this design can significantly reduce overall energy usage. Typical make-up air systems can achieve meaningful efficiency gains when using oval tubes, contributing to long-term system performance and energy savings.
Coilmaster oval tube coils are well-suited for applications where airside pressure drop, and energy efficiency are key design considerations. Systems that operate continuously or require high airflow volumes benefit the most from reduced fan energy requirements.
Typical applications include:
In these applications, reducing pressure drop improves system performance without requiring major changes to existing equipment.
By focusing on real-world performance and long-term efficiency, Coilmaster provides oval tube solutions that help customers reduce energy use while maintaining the cooling capacity their systems require.
With our new Oval Tube Technology we are able to reduce energy usage for a typical make-up air handler to about 12.5%.
Coilmaster combines advanced engineering with practical design to deliver coil solutions that improve performance and reduce operating costs. Oval tube technology reflects this approach by addressing one of the most impactful factors in HVAC system efficiency: airside pressure drop.
Each coil is designed and manufactured to meet specific application requirements, with attention to airflow, capacity, and system integration. Coilmaster’s experience in coil design, testing, and customization ensures reliable performance across a wide range of operating conditions.
