ZR-422B
Replaces R-22
ZR-422B is Precision Cold's patented R-22 replacement for residential and commercial air conditioning. It keeps aging R-22 equipment in service without retrofit work, while reduced compressor friction cuts the power the system draws to deliver the same cooling.
EPA Section 608: regulated refrigerants are sold only to certified technicians and qualifying businesses. Certification details are collected at checkout and purchase records are retained as required.
Hazmat shipping: refrigerant cylinders are compressed gas — ground service only, adult signature required, lower-48 US addresses, no PO boxes.
