Product Components:   

• Stands up to the toughest conditions 1,800° F flame temperatures and pool water chemistry are all in a day’s work for titanium.     

• Design elements that boost durability and efficiency. No welds, crimps or joints that reduce corrosion resistance. Tubing is shaped for maximum flow and efficiency.           

• Industrial chemical processors lean on titanium. When handling concentrated chlorine compounds, industrial processors rely on the corrosion resistance of titanium piping and heat exchangers.

Unmatched Durability And Efficiency:     

• EASY TO VENT PROPERLY: Fully sealed Category IV direct-air vent does not require large room openings for combustion air.    

• ULTRA-QUIET OPERATION: Great for you, great for your neighbors.
