Aquatherm’s Climatherm 98.5 percent pure polypropylene-random piping systems are designed for HVAC and industrial applications. It connects via heat fusion, which turns the pipe and fitting into a single material, creating long-lasting connections and eliminating toxic materials, glues, resins and open flames from piping installations. Climatherm (available in 3/8-inch to 12 inches) has an R-value of 1. A faser-composite layer reduces linear expansion of the pipe by up to 75 percent compared to plastic piping, ensuring it hangs rigidly even in operating temperatures up to 200 degrees F. Circle 46
