Tubeless Vertical Boilers
The Cyclone Hot Water Boilers provide for exceptionally high efficiencies, lower fuel costs, and extremely rugged construction. Compact space saving vertical design four-pass design shock proof, no tubes to loosen or burn out. Convenient access to "eye high" burner solid state controls for trouble free operation factory assembled, fully automatic UL and ASME CSD-1. Simple and inexpensive to install. Low water pressure drops. Standard design pressure of 30 PSI. Optional to 160 PSI, 250° F. LOW NOx meets California Standards (SCAQMD) for emissions & boiler operator exempt codes.
Boiler Feedwater Systems
The Hurst Feedmiser Automatic Return System provides storage for water make-up and return condensate from the system loop. When equipped with optional trim, the Feedmiser provides a quality, heavy duty packaged unit fully assembled and ready to install. The Hurst "Oxy-Miser" deaerating boiler feed water system eliminates the need of expensive oxygen scavenger chemicals. Guaranteed to remove oxygen in boiler feed water to .005cc/liter.
Firebox Boilers
Efficient 3-pass design, fuel flexibility for gas, oil, heavy oil, and combination gas/oil, ASME code constructed & stamped for 15 psi steam/30 water registered with the National Board of Boiler Inspectors, competitively priced, easily maintained, designed for efficiency, large furnace volume for ultimate combustion efficiency unified refractory base floor, steel skids and lifting eyes, low heat release.
LOW NOx Boilers
Boiler and Burner Technology Engineering for a Cleaner Environment. Hurst Boiler and LOW NOx have become synonymous names within the boiler industry. Hurst Boiler & Welding Company developed its first low emission boiler in 1992, and has been incorporating new technologies to improve upon this ever since.
Boiler Blowdown Separators
The HBC Blowdown Separator is designed to take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal. The HBC Separator accomplishes this by separating the subsequent flashed steam from the hot water.
