LJ Wing&reg - IFB Integral Face & Bypass Coils

L.J. Wing IFB horizontal tube integral face and bypass coils offer the most effective preheat system ever developed. The IFB coil controls air temperature while full steam pressure or water flow is maintained in the coil at all times. The preset discharge air temperature is held constant regardless of variations in the inlet air temperature. Ideally suited for make-up air, combustion air make-up, penthouse units, air conditioning preheat and heating and ventilating units. Performance can be calculated by using the L.J. Wing specifier program.

LJ Wing® VIFB • Integral Face and Bypass Steam Coils

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. The temperature of the discharge air is controlled by proportioning the entering air through the multiple heating and by-pass channels. The air is proportioned by the unique clamshell-shaped dampers which maintain a constant pressure drop, thus allowing a constant volume of air to pass through the unit. Performance can be calculated by using the L.J. Wing specifier program.

M-Series

MV-Series Multi-Header Vertical Face & Bypass Coils

For More Information:

L.J. Wing’s multi-stage face and bypass coils provide greater temperature control flexibility and offer more reliable VAV operation. Greater freeze protection and ease of installation than any other coil available is an added benefit of the new MV-series coils.

The multiple headers, controlled by slow acting on/off valves, provide close control of steam or hot water volume in the coils, allowing better control in VAV (variable air volume) systems. With increased damper control the MV-series coils also minimize temperature stratification and freezestat trips in mild weather.

Variable air volume with little temperature override, uniform air temperature, and maximum freeze protection make L.J. Wing MV-series coils an ideal component for any air handling system.
