For multiple boiler plants (up to 12 boilers), Micro IV™ controls firing rate to maintain pressure or temperature set point to meet load changes more efficiently by far than individual boiler controls. The microprocessor-based controller responds automatically to changing plant conditions. Micro IV™ provides the same increased efficiency for many process applications, too, including tank level control, air-compressor loading, and air dryer control.
On-Off, Low-High-Off, and Full Modulation (parallel or series mode) models are available. Sensors monitor and display steam pressure or water temperature continuously. Boiler status lights and manual/off/auto mode switches are provided. Auxiliary loop and monitor displays are available as options.
