L. J. Wing VIFB vertical tube integral face and bypass coils preheat outside air for air make-up systems. Because the VIFB coil operates with full steam pressure or constant water flow at all times, it prevents breakdowns in the central system caused by freezeup.

Wing VIFB integral face and by-pass coils provide reliable air preheating for air handling systems. This technical guide will help you size, select and specify the proper VIFB model to satisfy your project’s make-up air preheating requirements. If you have questions, please contact your local L.J. Wing representative; he will be glad to assist you.

For over 50 years freeze-resistant LJ Wing Integral Face and Bypass (IFB) coils have been installed in air handlers to allow large amounts of outside air all year round. Learn More
