The Hurst Advantage

Operational technology and IT integration is no longer optional—it's essential for competitive facility management.

Hurst intelligent control systems deliver:

  • Optimized fuel and combustion air management driving boiler efficiencies of 80–85%+

  • Lead-lag load balancing across multiple boilers to minimize cycling and fuel waste

  • Lower Fuel & Reduced Emissions precision air-to-fuel ratio maintains peak combustion reducing greenhouse gas and operating expense

  • Remote monitoring and control from anywhere via secure IIoT connectivity

  • Real-time alerts and insights that increase reliability and reduce downtime

Continuous Steam and Hot Water Demand Supply

Optimizes the boiler lead/lag operation by continually monitoring the
rate of change in steam pressure which allows multiple boilers to work
together efficiently to achieve system set points. Reduces boiler on-off
cycling due to system-load management.

Lower Fuel Costs and Reduced Emissions

Reduces greenhouse gas emissions by maintaining proper air-to-fuel ratios.
