Piping Solutions for HVAC Projects

When it comes to hydronic heating and cooling applications, Corzan CPVC offers an ideal combination of durability, reliability and affordability. Corzan CPVC pipe, valves and fittings are designed to meet the temperature, pressure and size requirements of commercial heating and cooling systems, and they have a proven track record in commercial hot water heating and cooling systems in hospitals, retail and multifamily projects, to name a few.

When designed, installed and operated in accordance with manufacturer recommendations, Corzan CPVC pipes and fittings are capable of operating at the temperature and pressures commonly found in commercial systems.

Beyond just its suitability for hydronic applications, Corzan CPVC also offers a handful of advantages for these projects:

Lower Cost, Easy Installation
A Corzan CPVC system costs less and is faster and easier to install than traditional metal systems, with no torches required, as well as versus the time-consuming, expensive fusion processes required for polypropylene. CPVC pipes and fitting install using one of two straightforward, affordable methods: solvent-welding or mechanical joining.

Piping systems for hydronic heating and cooling

Durability & Reliability
Corzan CPVC plumbing systems will not pit, scale, or corrode like metallic systems—regardless of water quality.

Lower Cost of Ownership
Unlike metallic materials, Corzan CPVC will not corrode over the life of the system and requires no additives or maintenance to prevent corrosion. CPVC also has lower heat transfer through the pipe wall when compared to metal systems.

Pipe and fittings made from Corzan CPVC are inherently less prone to biofilm growth than other materials. In addition, they can withstand ASHRAE 188 Guideline decontamination without risk of damage.

Flammability & Plenum Ratings
Corzan CPVC is self-extinguishing (Limiting Oxygen Index = 60). Corzan pipe and fittings meet the 25/50 flame spread/smoke developed requirements of the International Mechanical Code (IMC) and the Uniform Mechanical Code (UMC) for installation in plenums when tested in general accordance with ASTM E84. Reference ICC-ES PMG-1264 and IAPMO UEL-5002.

  • 1/2" - 6" water-filled Corzan CPVC pipe and fittings have a flame spread index of 0 and a smoke developed index of no more than 20.
  • 1/2" - 2" dry Corzan CPVC pipe and fittings for condensate lines have a flame spread index of no more than 0 and a smoke developed index of no more than 20.

Corzan SCH 80 pipes are available from 1/4" to 24" and with a full complement of solvent-welded fittings, along with mechanical couplings from 2" to 12".
