About LJ Wing

Known for engineering excellence and application-specific HVAC solutions, LJ Wing is best recognized as the original inventor of the integral face and bypass (IFB) coil—a design developed over 50 years ago to protect air handler coils from freezing, especially in systems that process large volumes of outside air.

LJ Wing continues to deliver proven, durable HVAC solutions across a wide range of demanding environments. Their steam and hot water IFB coils are used in hospitals, research labs, university facilities, and commercial buildings where precise temperature control and system reliability are critical.

As a brand with one of the lowest warranty claim rates in the HVAC industry, LJ Wing combines long-term reliability with deep engineering knowledge.
