  • Trailer-Mounted Watertube Rental Boilers
    Trailer-mounted rental boilers can be quickly delivered, installed and started-up anywhere in the world, requiring no cranes or rigging equipment. Sizes range from 30,000 - 125,000 lb/hr and we offer both saturated and superheated steam options....

  • The start of a new industry resulted in the mounting of a new 20,000 lb/hr package boiler on a permanent, highway-legal trailer by Nationwide Boiler in 1967. Today, Nationwide Boiler boasts the world's largest trailer-mounted rental boiler (125,000 lb/hr) and offers trailer-mounted boiler rental systems ranging in size from 30,000 lb/hr to 125,000 lb/hr with operating pressures from 300 - 750 psi (gas and/or #2 oil firing), including superheat units. Our boiler rentals are designed as completed engineered  "flange-to-flange" solutions, saving you time and valuable resources when compared to other rental companies.

    Benefits of a Trailer-Mounted Boiler

    Quick response - Boilers are mounted on dedicated highway-legal trailers and can be dispatched to a job site, frequently in just a few hours.

    Flange-to-Flange Solutions - Boilers are designed and engineered so all you have to worry about are connections to utilities and electrical requirements.

    No cranes or rigging required - There is no need for special handling to load or unload boilers at either your facility or the storage yard. This saves the user time and money.

    Simple to position and install - Custom dedicated trailers facilitate the maneuverability of trailer-mounted boilers.

    Fast, easy start-up - Because trailer-mounted boilers are essentially self-contained, only a connection to an electrical power source, water and fuel supplies, and a steam header are required for operation.

    Mobile steam plants feature firetube boilers ranging in size from 47.5 to 1,000 hp. These units are complete with feedwater system, water softener, chemical feedsystem, and blowdown separator, mounted on an open trailer or inside an enclosed trailer....

  • Over thirty years ago the first mobile steam plants were introduced by Nationwide Boiler, featuring firetube boilers in a range of sizes. The boiler was housed in a self-contained, highway-legal mobile van that was fully piped and wired and designed for outdoor installation (weather protected). Today, Nationwide Boiler carries both mobile steam plants on an open-trailer and mobile boiler rooms in an enclosed van, ranging in size from 47.5 - 1,000 HP, with operating pressures from 150 - 290 psi. The complete mobile steam plant systems typically feature a duplex water softener, chemical feed and blowdown system, and all valving and controls required for complete steam room operation. Electrical controls meet FM and NFPA 85 requirements.

    Many of our mobile steam plants are sub 9 ppm ultra low NOx have been pre-permitted for use in the SCAQMD, saving customers time and money relating to the application fees and processing time. Check out a complete listing of these units on our SCAQMD reference page.

    Benefits of a Mobile Boiler Room

    Enclosed work area - The entire steam plant, water treatment equipment and system controls are mounted inside a van-type structure.

    Inclement weather protection - No additional structures are required for protecting the equipment from rain or freezing temperatures.

    Personnel convenience - These units provide office space for maintaining logbooks, water chemistry testing, etc., and are designed for the comfort of boiler operators.

    Aesthetically pleasing - Mobile boiler rooms are attractive, which can be an important consideration if the temporary steam plant is going to be located in a place that is visible to the public.

  • CataStak SCR Systems
    The Nationwide CataStak™ is a portable, selective catalytic reduction (SCR) system capable of reducing NOx by up to 99% and is a cost-saving alternative to ultra low NOx burners. The CataStak is available for temporary and permanent applications....

  • The CataStak™ SCR system can be installed either vertically or horizontally and has been installed in applications ranging from boilers, gas turbines, fired heaters, HRSGs, and more.  It consists of a single-reactor housing with NOx reducing catalyst and/or CO oxidizing catalyst, and a standard reagent delivery system (pure anhydrous ammonia, aqueous ammonia, or urea). Nationwide Environmental Solution’s NOx reduction control system for the precise control flow of ammonia and an ammonia injection grid is also included. Based on design and operating conditions, the reagent can be directly injected or supplied by a vaporizer unit.

    With over 150 installations across North America, the CataStak can provide NOx reduction as low as 2.5 ppm NOx on both permanent and temporary applications.
