Heatcraft® Duct/Booster Coils – Efficient Heating for HVAC Systems
Heatcraft® Duct/Booster Coils are compact, duct-mounted reheat coils designed for hot water or steam heating applications. Commonly used to improve comfort in commercial and industrial HVAC systems, these booster coils provide reliable performance in a space-saving design.
Available in a variety of casing configurations—including fully flanged, slip-and-drive, or end plates only—Heatcraft® Booster Coils can be tailored to fit new installations or retrofit projects. Multiple fin designs are also offered to optimize heat transfer performance and manage airside resistance.
The most common construction combines copper tubes with aluminum fins housed in a galvanized steel casing, giving customers a cost-effective, durable solution. Standard copper, steel, or brass connections are available, with custom-engineered options designed by Modine for harsh or specialized operating conditions.
Whether you need to add heating capacity, improve efficiency, or fit tight ductwork spaces, Heatcraft® Duct/Booster Coils deliver reliable heating performance and long service life.
