Boiler Controls

We deliver comprehensive boiler combustion control systems, ranging from precise single-point positioning to fully metered-cross limited control. Our offerings include advanced features like:

  • Oxygen Trim
  • Drum Level
  • Draft Control

Our intuitive Human-Machine Interface (HMI) consolidates burner management with first-out annunciation, providing a unified control center.  Each system is seamlessly integrated for effortless operation and troubleshooting. We also offer control of the balance of the plant, which encompasses crucial elements such as DA level and pressure, steam header pressure, and sequencing of boiler feedwater pumps.

Chiller Controls

Operating more chillers than necessary to maintain space temperature conditions is an issue for all plant operators. We can provide a fully integrated system to stage and sequence chillers based on real-time chilled water demand, optimizing performance. Additionally, we calculate and manage cooling tower, chilled water, and condenser pump requirements and stage them accordingly to ensure efficiency at every step.
