Wing® Integral Face and Bypass Steam Coils
IFB
Integral Face and Bypass Coils
For More Information:
Wing IFB horizontal tube integral face and bypass coils offer a highly effective preheat system. The IFB coil controls air temperature while maintaining full steam pressure or water flow in the coil. The preset discharge air temperature is 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. The L.J. Wing specifier program can calculate performance.
VIFB
Integral Face and Bypass Coils
For More Information:
Wing VIFB vertical tube integral face and bypass coils preheat outdoor air for air makeup 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 freeze-up. The unit controls the discharge air temperature by proportioning the entering air through the multiple heating and bypass channels. The unique clamshell-shaped dampers proportion the air, maintaining a constant pressure drop, thus allowing a constant volume of air to pass through the unit.
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.
