High-Capacity Industrial Steam Solutions: Nationwide Boiler’s World’s Largest Trailer-Mounted Boilers

Nationwide Boiler proudly offers the world’s largest high pressure mobile steam boilers for industrial applications: the 150,000 pph saturated steam boiler and the 110,000 pph superheated Steam boiler, both trailer-mounted for unmatched mobility and rapid deployment. These high-capacity rental boilers set the industry standards for performance, flexibility, and reliability, delivering robust steam output for the most demanding industries.

Engineered for Performance and Flexibility

The 150,000 pph saturated steam boiler is engineered to provide consistent, high-volume steam for industries requiring a dependable temporary steam supply. With a design pressure of 650 psi and an operating range from 350 to 600 psi, this unit delivers exceptional operational flexibility and reliable output.

For applications demanding higher steam temperatures, the 110,000 pph superheated steam boiler is the ideal solution. This unit has a design pressure of750 psi and is built to supply 750°F superheated steam, with an operating range from 350 to 680 psi. Both boilers are trailer-mounted with removable gooseneck and running gear, ensuring true mobility, rapid installation, and flexible site placement for both temporary and long-term use.

Standard Features for Industry Leading Performance

• PLC Based Combustion Controls: Advanced, user-friendly controls for safe, efficient, and fully metered operation.

• EconoStak™ Economizer: Recovers heat from flue gases to enhance fuel efficiency and reduce energy costs.

• VFD Controlled Forced Draft Fan: Provides precise airflow control for optimal combustion.

• Comprehensive Safety Systems: Includes safety valves, low water cutoffs, and NEMA 4 electrical enclosures for reliable, safe operation.

• Emissions Compliance Options: Optional CataStak™ SCR system supports compliance with stringent emissions standards, offering ultra-low NOx performance down to 2.5 ppm.

• Flexible Fuel Options: Designed for natural gas, with capability for #2 oil and hydrogen blend fuels. 

• Trailer Mounted, Highway Legal Design: Removable gooseneck and running gear for flexible site placement and rapid deployment.

Both package watertube boilers are fully piped, wired, and tested before shipment, ensuring seamless setup and compliance with ASME, FM, NFPA 85, and GE GAP Insurance Standards. Additionally, boilers are weatherproofed (except for freezing conditions) and come with comprehensive operating manuals.

Saturated or Superheated Steam: Selecting the Optimal Solution

• Saturated Steam: Ideal for applications requiring fast, even heating such as process steam and heating, sterilization, and district energy. Saturated steam is efficient for heat transfer and can be easily controlled through pressure adjustments.

• Superheated Steam: Best suited for power generation and turbine driven equipment. Superheated steam remains dry at higher temperatures, improving thermal efficiency and reducing the risk of equipment corrosion.
