Product description

The Boiler & Welding Co., Inc. introduces the Series 400, a robust high-pressure boiler engineered with a 3-pass Scotch Marine design featuring stress-relieving wetback construction. This advanced boiler serves capacities from 30 to 1500 Boiler Horsepower (BHP) and outputs between 1004 and 50213 MBTU/HR. Designed for both steam and hot water applications, the Series 400 achieves steam pressures from 15 to 300 PSI.

Key Features

The Series 400 boiler is built with several distinctive technological features:

  • Wetback Construction: Eliminates the need for costly refractory rear doors and baffles, minimizing maintenance demands.
  • High Efficiency: Promotes superior water circulation and rapid heat absorption due to its full wetback radiant heat transfer area.
  • Modular and Skid-Mounted Design: Allows for easy installation and integration into existing systems.
  • Versatile Fuel Options: Accommodates natural gas, propane, No. 2 (diesel) oil, or a combination of gas/oil fuels with UL listed "forced draft" power burners.

Standard Steam Trim

  • Safety relief valve and operating pressure control
  • Steam pressure gauge with syphon and test cock
  • Low water cut-off and pump control with gauge glass assembly

Standard Water Trim

  • Combination pressure and temperature gauge
  • Probe type low water cut-off control with manual reset
  • Hot water return baffle for shock resistance

Ideal Use Cases

The Series 400 is ideal for applications requiring rigorous, continuous operation such as in industries like petrochemical, food processing, and textile manufacturing. Its durable design ensures reliable function even under extreme demands, making it a solid investment for any high-pressure steam or hot water application.
