With a capacity of 3 million Btu per hour, Benchmark 3.0 high-efficiency boilers have a 79-in. height, 28-in. width, and 64-in. depth. The gas-fired units deliver a turndown of 15-to-1 to maximize operating efficiency and seasonal fuel savings. The boilers are fitted with a low-nitrous-oxide (NOx) burner, which has NOx-emission levels of less than 30 ppm.
A brochure from Industrial Steam describes the company's pressurized steam-flow deaerators, which can reduce boiler-feed-water gas content to 0.005 cc per liter. The brochure has sizing and sequence-of-operation information.

RMB Ultra burners are designed to meet the needs of large firetube, commercial watertube, and small industrial watertube boilers. The burners have capacities of 700 to 2,500 hp or 30 million to 105 million Btu per hour. The burners' low NOx-emission levels range from 9 to 30 ppm when firing natural gas.

The Wils-Away 1500, an electric tube-cleaning system for straight and curved tubes in firetube boilers, air and water heaters, heat exchangers, condensers, chillers, absorbers, coolers, and other pressure vessels, removes soot and scale. Each unit is equipped with a safety shaft coupling that snaps under accidental overload, protecting the shaft from breakage. Collecting soot, 2-hp and 4-hp vacuums give cleaned tubes a polished look. Each kit includes an electric drive unit and all accessories and tools required for tube cleaning.
