The Nu-Calgon Rx-Acid Scavenger Connect Inject Acid Treatment Kit (CA-430106) is a complete injection solution designed to deliver Rx-Acid Scavenger into HVAC and refrigeration systems without system shutdown. This Connect Inject configuration allows technicians to introduce the acid-neutralizing additive into operating systems to scavenge acid contamination in system oil following burnout or during corrective maintenance. The kit is intended for use with compatible refrigeration oils and systems where controlled, in-service chemical injection is required. Proper job-fit verification includes confirming system operating conditions, oil type compatibility, and correct treatment dosage based on total system oil volume.
