Watertube steam boilers are of the “D Type” design which is well known for its efficiency and simplicity. This design utilizes large radius tube bends and limits the required number of bends which reduces the stress on the tube and increases the unit life.
All units are factory packaged with operating controls, relief valves, burner and fuel train. Installation is made simple in that only service connections are needed to place in operation. Flexible burner systems are available for firing natural gas, LP gas, #2 oil, heavy oil, or combinations. High density 4” mineral wool insulation assures lower radiant heat loss.
