Assembled chillers were charged with refrigerant for pre-shipment performance testing and shipment, creating opportunities for accidental releases. The average leak could result in a loss of approximately 600 pounds of refrigerant.
Leaks have been reduced 90% due to a design change in the chillers. The valves formerly involved in the leaks have been upgraded and relocated to avoid any contact during movement.
To further prevent spills, a containment vessel was designed to capture the refrigerant. Weekly preventative maintenance checks are performed on the recovery units, reducing risk of contamination by 85%. Any leaked refrigerant that becomes contaminated is sold to a reclamation center that purifies it for resale.
A 90% reduction in refrigerant leaks equates to remarkable environmental benefits, due to the toxic nature of refrigerant chemicals. York International has greatly reduced their Toxics Release Inventory (TRI) chemicals.
