IFB (Integral Face and Bypass) Coils

The most effective preheat system ever developed!

Horizontal IFB Coils

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.

Vertical IFB Coils

The VIFB coil operates with full steam pressure or constant water flow at all times, so it prevents breakdowns in the central system caused by freezeups. 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, allowing a constant volume of air to pass through the unit.
