ProCore™. A powerful defender against VOC damage.


Over time, copper tubing used in a HVAC system can corrode with constant exposure to dampness and VOC's that are in the air. Corrosion forms horizontally across the surface of the tube which inhibits oxidization from penetrating deeper into the copper and eventually causing a leak. In the most corrosive environments, new ProCore™ tubing will maintain the integrity of the refrigeration system with no reduction in capacity or service to the end user. Just one more way Fujitsu is bringing you Infinite Comfort!
