Manufacturing Steam and Hot Water Boilers Since 1931
Immersion Fired Steam Boiler
The sellers immersion fired S series steam boiler is a horizontal, single pass, firetube boiler design to burn natural gas. The unique burner assembly delivers pre-mixed air and gas through multiple nozzles. The air gas mixture is ignited as it exits each flame retaining nozzle at high velocity. The resulting flames are long and small in diameter.
The flame from each of these nozzles is directed into a 2 inch OD tube that is completely immersed in liquid. There is a separate tube for each flame with the same amount of heat going into each tube. The small diameter flames burn in the first half of the two blanks. The sellers single pass design allows small diameter flames to burn in the first half of the two blanks providing 50% radiant heating service.
The high percentage of radiant heating surface, the low heat and put into each tube, and the even distribution of heat throughout the multiple tubes virtually eliminate thermal stress problems that are common in multiple pass boilers.

|Full Modulation with Parallel Positioning Controls||Lowest Life Cycle Maintenance Costs|
|Single Source Burner - Boiler Package||Absolutely No Refractory|
|Five Year Non Pro-rated Burner Warranty||U.L. Labeled Packaged Boiler|
Net Stack Temperature and Efficiency Rating
|10 PSI||50 PSI||100 PSI||125 PSI|
|40 - 200||289° (83.5%)||345° (82.1%)||384° (81.2%)||399° (80.8%)|
|250 - 800||267° (84.0%)||321° (82.7%)||359° (81.8%)||373° (81.4%)|
When unit is in proper adjustment. Net stack temperature based on 70° ambient air temperature. Addition of 30 ppm and NOx option will lower efficiencies slightly.
Quick Heat Indirect Water Heater
Key features of this indirect “semi-instantaneous” commercial or industrial steam water heater generator includes:
- Excellent Warranty – one year on the heat exchanger
- ASME Section VIII and U Stamp certifications
- Minimum Floor space requirement
- Compact fully assembled packaged system
- Vertical or horizontal orientation
- Up to 460gpm with an 80 degree temperature rise
- Safety controls: Electric Hi Limit, Safety solenoid system, and Bronze water pressure relief valve
- Pneumatic or self-operating valve
- Stainless steel or copper water wetted surfaces
- Single-wall or optional double-wall heat exchanger
- 3 – 176 gallons per minute
Our “Quick Heat” indirect semi instantaneous steam to water hot water generator utilizes steam or hot water from a boiler to generate hot water quickly (up to 460gpm). The unit is built in accordance with Section VIII of the ASME code and “U” stamped for 150 psi. The unit is completely factory packaged. It can produce large volumes of hot water and steam while occupying little floor space. A stainless steel mixing chamber eliminates corrosion and erosion while assuring uniform temperatures at any flow rate.
