Face and By-pass Heating Coils—Duramix™

Description

Armstrong Duramix heating
coils control air temperature while operating at full steam pressure.
Once set, the desired leaving-air temperature is maintained by Duramix™
regardless of variations in the temperature of the entering air. The
Armstrong Duramix™ heating coil is simple, yet very effective, and it is
easy to install and maintain.

How Duramix Face and By-pass Coils Work

Special dampers, controlled by a pneumatic actuator connected to a
temperature sensor, adjust the leaving-air temperature by channeling the
appropriate volume of entering air across the heating coils and
allowing the remaining air to pass through by-pass channels. As entering
air temperature gets closer to or farther from the set point, the
dampers are closed or opened accordingly.

Armstrong Duramix heating coils combine the advantages of
a face and by-pass system with the quality and heavy-duty construction
that are part of every Armstrong coil. From an all-welded, monometallic
coil to corrosion-resistant linkages to a tough casing assembly,
Armstrong Duramix coils are built to provide long-lasting service. Our
Duramix units can have vertical or horizontal louvers.

Duramix provides:

  • Maximum freeze protection
  • Accurate temperature control
  • Consistent leaving-air temperature

Typical applications:

  • HVAC air preheat systems
  • Make-up air systems
  • Combustion air preheat systems
