• Variable-speed drive option
• Works with standard or Siemens gas trains
• User-friendly setup

  The Cleaver-Brooks Accu-Trim O2 Trim System is a stand-alone, PLC-based control system designed to maintain the proper fuel-to-air ratio of a boiler/burner. The system will automatically compensate for changes in temperature, barometric pressure, or fuel characteristics, as well as correcting for normal hysteresis. The system is intended for use with single-point positioning, or jackshaft-type, combustion controls; however, it may be customized for special applications such as parallel positioning or alternate fuel firing. A complete system includes oxygen and firing rate sensors, a control panel, which houses the PLC, and an actuator or VSD system, which trims either the fuel or airflow.
  Design options include the custom C-B O2 Probe and industrial O2 probes such as Yokogawa. A variable-speed drive is used to provide fuel or air trim. The C-B Accu-Trim works with standard or compact fuel trains such as the Siemens valve assembly. Setup and operation are easy with the user-friendly HMI.
