Round Tube Finned Coil

At Harsha Engineers, we design and manufacture durable Round Tube Finned Coils that deliver efficient heat transfer in heating, cooling, and dehumidification applications. These coils are built with round tubes fitted with high-performance fins, which increase the surface area for maximum thermal efficiency.

Round tube finned coils are widely used in HVAC systems, refrigeration units, process cooling, power plants, and chemical industries. They provide reliable performance where compact design, energy efficiency, and consistent heat exchange are critical.

Constructed from high-quality materials such as copper, aluminum, stainless steel, or mild steel, our coils are engineered to withstand corrosion, high pressure, and demanding operating conditions. With precision fabrication and strict quality checks, Harsha Engineers ensures long service life and dependable operation.

Tube Material: Copper, Stainless Steel, Carbon Steel, Aluminum, Brass.
Fin Material: Aluminum, Copper, SS.
Tube Diameter: 6 mm to 38 mm.
Fin Type: Continuous fins, segmented fins, or spiral fins.
Fin Pitch: 1.5 mm to 5 mm (customized as per application).
Coil Length & Height: Designed to client specifications.
Coating Options: Epoxy, hydrophilic, or anti-corrosion coatings for extended life.
Design Pressure: Up to 30 bar.
Design Temperature: -40°C to +200°C.

The primary fluid flows inside the round tubes, while the secondary fluid (air or another liquid) flows across the external fins.
The fins increase the surface area, improving heat transfer between the fluids.
Heat is exchanged efficiently through conduction (tube to fin) and convection (fin to air/liquid).
These coils are commonly used in applications where compact design and high heat transfer efficiency are required.

Round Tube Finned Coils are highly versatile and are used across multiple industries:

HVAC Systems – Air conditioning, heating, and ventilation.
Refrigeration Industry – Condensers and evaporators.
Power Plants – Heat recovery and air preheating.
Chemical & Petrochemical – Process fluid heating/cooling.
Food & Beverage Industry – Cold storage, cooling tunnels, and dryers.
Pharmaceuticals – Controlled temperature applications.
Automotive & Marine – Engine cooling and oil cooling systems.

High heat transfer efficiency due to increased surface area.
Compact design with high thermal performance.
Energy efficient, reducing operational costs.
Durable construction with corrosion-resistant materials.
Customizable designs for specific applications and environments.
Easy installation and maintenance.
Reliable performance in both heating and cooling applications.
