SureFit coils, introduced by Trane, are a single-source solution for replacing heating, ventilation and air-conditioning coils. The coils meet the requirements of most HVAC systems, regardless of the manufacturer. Internally enhanced tubes improve efficiency and ease of maintenance. Enhanced fin design improves performance by providing low airside pressure drops, reduced moisture carryover and maximized heat transfer. An optional coil coating protects coils from corrosion and chemical damage.
