Delphi Combustion System
YP900 Delphi Combustion Efficiency Panel
Delphi Combustion Efficiency Panel is a packaged, pre-wired panel
with integrated color touchscreen display, flame safeguard control,
linkageless fuel/air ratio control, oxygen trim and VFD capability.
Includes Hall-effect sensor which monitors VFD-driven blower and
provides feedback to the control, certain models include the
MF020-1-LC3 Oxygen sensor with mounting fitting and electrical
connector. System is set-up entirely via the touchscreen interface.
• Works with a variety of burners and boilers
• Components housed in one panel
• Integrated flame safeguard control and linkageless fuel/air
ratio control with oxygen trim
• Dual Fuels allowed with independent profiles
• Oxygen trim compensates for variable combustion air
• Certain models include high accuracy O2 sensor with quick
response and open air calibration (MF020-1-LC3)
• VFD control capability (Honeywell NXL or NXS Series)
• Large color touchscreen interface
• Available actuators from 100 to 400 b-in.(ML7999B or Herculine 2001)
• Embedded software for commissioning, control and monitoring
• Dedicated actuator and VFD channels with feedback
• Up to 4 independently controlled actuators
• Firing rate/load control via temperature, pressure or manual operation
• 24 Vdc industrial panel PC control
