Package boilers integrate multiple systems into a single skid, boiler vessel, burner, FD fan, feedwater pumps, deaerator, blowdown vessel, and BMS controls. This means the spare parts inventory spans mechanical, combustion, electrical, and instrumentation categories.
AQ Process Systems sources and exports spares for both fire-tube and water-tube package boiler configurations. We cover the boiler internals (tubes, gaskets, refractory) as well as the package-specific auxiliaries (burners, fans, pumps, controls) that are often proprietary to the package manufacturer.
For package boiler operators, we offer consolidated spares packages covering all recommended maintenance items, reducing procurement effort and ensuring all parts arrive together for a planned shutdown.

| Modulating Motors & Actuators | Combustion air & fuel valve actuators | Servo motors and pneumatic actuators for burner air damper and fuel valve modulation. |
| Transmitters & Switches | Pressure, temperature, level, flow | All field instrumentation, transmitters, switches, gauges, and thermowells for the package system. |
| Electrical Panels & Wiring | Starter panels, VFDs, junction boxes | Motor starters, variable frequency drives, junction boxes, and interconnecting wiring harnesses. |
Parts are matched to OEM material specifications and dimensional tolerances. Please provide the equipment manufacturer, model number, and serial number (if available) for precise part identification. Mill Test Certificates (MTC) supplied with all tube materials per EN 10204 3.1.
Package boilers integrate the boiler vessel with all auxiliaries on a single skid, burner, FD fan, feedwater system, deaerator, and BMS controls. This means spares span multiple systems: boiler vessel parts (tubes, gaskets), combustion parts (burner, flame safeguard), rotating equipment (pumps, fans), and electrical/controls (BMS, actuators, transmitters). A single supplier covering all categories simplifies procurement.
Yes. We supply replacement BMS programmer modules, flame relay modules, and associated sensors compatible with Honeywell, Siemens, Fireye, and other BMS manufacturers commonly used in package boilers. Parts are matched to the existing system for plug-and-play replacement.
Yes. We offer consolidated shutdown spares packages that include gaskets, burner wear parts, flame scanner, feedwater pump internals, safety valve (for recertification), level gauge glasses, and refractory patch material, all in one shipment, matched to your specific boiler make and model.
Yes. We supply forced-draft fan impellers, shaft bearings, flexible couplings, vibration switches, and replacement motors. Parts are matched to the fan make and model installed on your package boiler system.
Consumable items (gaskets, electrodes, gauge glasses) are typically available within 1-2 weeks. Burner assemblies, BMS controllers, and pump sets may require 3-6 weeks. We recommend maintaining a critical spares inventory for items with long lead times, we can help you define this list based on your boiler model.
