Downtime often comes down to parts availability. JC Boiler maintains access to critical boiler parts and skid boiler rentals to support emergency replacements, temporary capacity, and planned maintenance.

We inventory high-failure components and wear items that cause the most operational disruption when they fail. For specialty parts, OEM components, or less common equipment, we leverage decades of supplier relationships to source quickly.

• Burners and combustion components: Burner motors and couplings, ignition transformers and electrodes, flame rods and UV scanners, fuel nozzles and spray tips, air dampers and linkages, burner gaskets and mounting hardware.

• Controls and instrumentation: Operating controls (pressure, temperature, modulating), limit controls and high-limit switches, flame safeguard systems, low water cutoff devices, aquastats and immersion thermostats, pressure transducers and gauges, flow switches and proving switches.

• Pumps and motors: Feedwater pumps and rebuild kits, condensate return pumps, circulating pumps for hot water systems, pump seals and mechanical seals, motor starters and contactors.

• Safety and pressure relief components: ASME pressure relief valves (steam and hot water), safety valve test equipment, blowdown valves and bottom blowdown piping, pressure relief valves (PRVs) / pressure safety valves (PSVs), backflow preventers and check valves.

• Feedwater treatment and chemical systems: Chemical feed pumps and injection systems, water softeners and filtration equipment, deaerator components and vent valves, boiler compound and treatment chemicals.

• Gaskets, seals, and tube components: Handhole and manway gaskets, tube ferrules and rolled tube seals, flange gaskets and high-temperature sealants, door gaskets and insulation.

• Fuel handling components: Gas valves and regulators, oil pumps and strainers, fuel filters and cartridges, flame retention heads and nozzle assemblies, dual-fuel conversion components.

• Electrical components: Relays, contactors, and transformers, flame amplifiers and control modules, actuators and damper motors, thermocouples and RTDs, wiring harnesses and terminal blocks.
