Product description

Hurst Series 400 High-Pressure Boiler

The Hurst Series 400 is a state-of-the-art high-pressure boiler engineered for robust industrial applications. Designed on a three-pass "Scotch Marine" firetube configuration, it features wetback construction, greatly reducing the need for maintenance and replacing conventional refractory rear doors and baffles that are prone to rapid deterioration.

Key Features

  • Boiler Horsepower ranging from 30 to 1500 BHP, supporting diverse energy needs.
  • Steam capacities from 1004 to 50213 MBTU/HR with pressures scaling up to 300 PSI.
  • Hot water applications compliant with ASME Section I and Section IV, including high-pressure variants up to 160 PSI.
  • Skid-mounted, modular packaged configuration for easy installation and integration.

Technical Advantages

The wetback design stands out as it addresses the shortcomings of dry back boilers, including refractory degradation and inefficient baffle systems. This innovation promotes efficient heat absorption and optimal internal water circulation, ensuring prolonged service life and reduced operational costs.

Standard Trim and Specifications

  • Includes safety relief valves, operating pressure/temperature controls, and high-limit controls with manual reset features.
  • Trimmed in compliance with strict ASME, UL, and CSD-1 standards.
  • Equipped with factory pre-piped, wired and tested UL listed "forced draft" power burners, compatible with natural gas, propane (LP) gas, No. 2 diesel oil, or hybrid gas/oil options.

Ideal Use Cases

These boilers are highly suited for industries requiring consistent high-pressure steam or hot water for prolonged operations. Applications span across manufacturing, chemical processing, and district heating sectors.
