Fireye Nexus® PPC4000 is a state-of-the-art Parallel Positioning System for all types of liquid or gaseous fuel-fired combustion systems. When combined with a Fireye flame safeguard system such as the BurnerLogix™ Control, the PPC4000 offers a compact parallel positioning system.

The PPC4000 provides precise control of burner air/fuel ratio via independent motors (Parallel Positioning) along with four servo channels for positioning motors, directly powered from the controller.
The Fireye PPC4000 also provides sequencing (lead-lag) control and simplified wiring via removable plug-in connectors. The system offers operating & logged data stored on SD card and user-programmable digital inputs.

Benefits:

• Increased Efficiency
• Reduced Fuel Consumption
• Reduced Emissions
• Reduced Downtime & Maintenance

Fireye Nexus® NXM2G is an intelligent micro -processor based Boiler Load Optimization Control System designed to reduce energy costs by providing optimum thermal efficiency of low temperature hot water boilers.

The NXM2G is designed to prevent boiler dry cycling which occurs when a boiler loses heat to its surroundings. The NXM2G is fully compatible with existing control systems and building management. Designed for use with low & medium temperature water boilers, single stage burners, fully modulating burners and many more.

Fireye Nexus® NXEXP300 is a microprocessor-based, Water Level & Draft Control Expansion Module for use with the Nexus PPC6000 or integrated NX6100 series of parallel positioning controls.

The Fireye NXEXP300 expands the capability of the parallel positioning system by adding valuable safety-rated digital inputs, sequence draft control, boiler water level control, and total dissolved solids (TDS) surface and bottom blowdown control. The small footprint (5” L x 8.5” W x 3.75 H), adjustable voltage (120/230, 50/60 Hz.) and simplified wiring, provide easy retrofit to existing Fireye Systems.

Benefits:

• Boiler Water Level
  One, Two or Three-element boiler water level control via 4-20mA inputs from field devices. Feed pump VFD and pump sequencing is also included.
• Sequence Draft Control
  Built-in sequence draft control controls the boiler outlet damper through pre-purge, light off and operation reducing standby and operating losses.
• Total Dissolved Solids
  Industry-standard TDS probe provides the option to control surface blowdown based on TDS levels set by operators.
• Flexibility
  Utilize proven Fireye CANbus servomotors or industrial 4-20mA current or I/P feedwater valves.
• Wiring
  International voltage setting and simple four-wire CANbus interconnections make wiring a snap. Safety relay contacts can be easily inserted into the existing control wiring.
• Reliable Operation
  Proven hardware with more than five years of in-field service has been reconfigured to provide these additional features.

Fireye Nexus® Combustion Efficiency Systems include a wide range of add-on options such as:

• Keypad Displays & Touchscreen Interface Panels
• Plant Master Panels
• Pressure & Temperature Sensors
• Oxygen Probes (for use with NXF4000, PPC4000, NX6100, PPC6000, & Stand-Alone Systems)
• Variable Frequency Drive (add-on Cards & Full Systems)
