Nu-Calgon AC Renew 4oz Can 4057-55

A/C Re-New (formerly Zerol® Ice) from Nu-Calgon is a professional-grade lubricant treatment engineered for both air-conditioning and refrigeration systems. Designed to mix seamlessly with system oil and last until the next oil change, A/C Re-New delivers major performance benefits:

• Quieting noisy compressors and reducing wear on moving parts

• Lowering starting and running amperage draws to enhance energy efficiency

• OEM-approved and suitable for use in new or older systems

• Aiding oil return in R-22 retrofit applications and in systems using R-410A or other refrigerants

• Simple to apply: treat up to 5 tons with the 4 oz can, or use larger sizes for large‐capacity or commercial systems

Ideal for contractors servicing residential split-systems, rooftop packaged units or commercial refrigeration, A/C Re-New is a reliable way to extend system life, reduce maintenance calls and improve performance. Use with the recommended injector tool for best results.
