HOW SHOULD FRIGI-TECH BE STORED AND SHELF LIFE?
Frigi-Tech should be stored in a cool dry place. The shelf life of Frigi-Tech is indefinite as long as the foil seal has not been broken and has been stored properly. If the foil seal has been broken, we recommend purging the container with Dry Nitrogen before storage and before the next use. If the Frigi-Tech's normal color has darkened (low temp blend dark brown and in mineral and POE blends dark golden brown), it is a sign of oxidation and should not be used in any HVAC equipment.
