SEALING

Sections are fully machined at their joints providing for line contact between sections. They are sealed with a high temperature sealant. Water joints are accurately machined and sealed with graphite rings resistant to corrosic and temperature extremes.

Cast iron heat exchanger accepts a wide range of water flows with 1/5 the energy density and 5 times the wall thickness of copper boilers

  • Cast Iron heat exchanger rated at 100 PSI working pressure
  • No inlet water temperature limitations
