HEATING COIL
At KRN Heat Exchanger & Refrigeration Ltd., our Heating Coils are engineered to provide reliable and efficient heating for HVAC systems, industrial processes, and specialized applications. These coils work by transferring thermal energy from a hot medium—such as steam, hot water, or thermal oil—into the air stream, ensuring consistent comfort, process heating, and energy efficiency.
Designed with robust construction and premium materials, our heating coils deliver long service life, high performance, and adaptability to suit both standard and demanding environments.
Design & Construction
- Tube Material: Copper (standard), copper-nickel, or stainless steel (for corrosive or high-temperature applications)
- Tube Diameters: 3/8” (9.52 mm), 1/2” (12.7 mm), 5/8” (15.88 mm)
- Wall Thickness: 0.28 – 1.0 mm (based on duty requirements)
- Fin Material: Aluminum (standard), copper, or epoxy/hydrophilic coated fins for corrosive environments
- Fin Thickness: 0.12 – 0.30 mm
- Fin Pitch: 1.6 mm – 3.2 mm (customizable for airflow resistance and efficiency)
- Rows Available: 1–12 rows depending on heating load and system design
- Casing: Galvanized steel, stainless steel, or aluminum casings for durability
- Testing: 100% of coils are pressure-tested up to 400 psi (27.5 bar) to ensure leak-free performance
