Industrial Steam
Series HF/HW Boiler
15 to 200 HP Packaged Boilers
15 psi Steam or 80 psi Hot Water
3-pass firetube boiler operates at high efficiencies due to effective heat transfer across all heating surfaces. Submerged combustion chamber improves water circulation and adds to direct heating surface.
Compact design fits through a 36″ doorway and occupies a small footprint per boiler horsepower. Front and rear water legs eliminate the need for side connections.
Built, inspected, and stamped in accordance with Section IV of the ASME code. Tubes are rolled and flared to facilitate maintenance*.
U-Type Flex Joint design minimizes the destructive effects of differential stress as furnace expands at a greater rate than tubes during firing.
Structural steel skid with slots for forklift handling.
Custom fabricated bent steel turbulators insure positive furnace pressure necessary for highest noncondensing combustion efficiencies (83% +/-)..
Smokeboxes are easily removed for transporting boilers through existing elevators and stairwells. Bolted and gasketed construction provides convenient access to tubesheets for inspection, cleaning, and tube maintenance.
All flue gas reversing chamber surfaces except for rear access door are water-cooled, insuring maximum heat transfer efficiency and minimal thermal shock. Removable rear door provides easy access to furnace interior.
* Welded tubes available upon request.

Series VW Boiler
Direct Hydronic Boilers
Applications: 30 to 100 psi Hydronic
Outputs: 165 to 2750 MBH Packaged Boilers,
Modular Heating Plants for Any Capacity
Fuels: Natural or Propane Gas, #2 Oil, Combination
Low Stress Design: Single pass construction eliminates differential expansion forces across heads, permitting design return temperatures as low as 70°F and immediate “cold starting” response to all call for heat. Boilers are warranted for five years against thermal stress leaks regardless of return temperature. Consult L.E.S. for boiler configuration/control options required for direct very low temperature operation.
High Efficiency: Series VW boilers are positive pressure non-condensing appliances. They are equipped with forced-draft burners for reliable 83% efficient combustion. High-temperature fiberglass rope is used to gasket burner flanges to burner ports and steel lids to flue-gathering chambers. Custom-fabricated bent steel turbulators installed in fire-tubes limit flue gas velocity, insuring maximum heat transfer. Heat losses associated with draft hoods and barometric dampers are eliminated and breeching/stack sizes can be reduced.
Steel Skids: Structural channel skids create a space (3″ minimum) beneath boiler shells which may permit elimination of a poured concrete pad. Boilers can be rolled into place on steel pipes, levered into precise position, and easily/securely leveled by shimming of skids.
