Used Boilers
Boilers generate and transfer thermal energy to support heating, process temperature control, and steam generation across industrial operations. These systems circulate heated water, steam, or thermal fluids through closed loops to deliver consistent temperatures for manufacturing processes, cleaning systems, and facility heating.
Federal Equipment Company stocks a range of used boilers, including hot oil and water boilers and package steam boilers. Available units range from compact temperature-control units under 5 kW to large-capacity systems exceeding 300 kW, with configurations for single- and multi-zone operation.

Industrial boilers transfer thermal energy by heating a working fluid—water, steam, or thermal oil—and circulating it through a closed system to process equipment or facility heating loops. The choice of heat transfer medium depends on the required operating temperature, process compatibility, and safety considerations.
Hot oil systems (also called thermal fluid heaters) circulate synthetic or petroleum-based oils that remain liquid at temperatures up to 650°F, making them suitable for applications requiring high heat without the pressure hazards of steam. Water-based systems operate at lower temperatures and pressures, providing efficient heat transfer for applications below 250°F. Package steam boilers generate pressurized steam for direct injection, sterilization, or process heating, where latent heat recovery improves efficiency.
Core components include the heating element (gas-fired burners or electric resistance heaters), circulation pumps, expansion tanks, temperature controllers, and safety devices such as pressure relief valves and high-temperature cutoffs. Electric units offer precise temperature control and simplified installation without combustion venting requirements.
Federal Equipment Company stocks units from leading manufacturers of industrial heating equipment. Available configurations include single-zone and multi-zone temperature control units, skid-mounted hot oil systems, and packaged boilers with integrated controls. Electric heater capacities range from 2.5 kW to 300 kW, with gas-fired units rated up to 2.5 million BTU input. Our team can provide inspection, testing, and refurbishment services based on your application requirements.

Why Buy Used Boilers
Used boilers offer significant cost advantages over new equipment, with savings typically ranging from 40% to 60%, depending on age, condition, and configuration. Because properly maintained boiler systems can operate reliably for decades, purchasing used equipment provides a practical way to expand capacity or replace aging units without extended lead times.
New boiler procurement often requires weeks or months for manufacturing, especially for custom configurations or large-capacity systems. Used equipment from Federal Equipment Company is available for immediate inspection and faster delivery, helping minimize production downtime during equipment replacement or facility expansion projects.
Federal Equipment Company can provide inspection, pressure testing, and refurbishment services to verify equipment condition and performance before delivery. Our technical team can help match available inventory to your specific temperature, capacity, and configuration requirements.
