Nu-Calgon 4057-55 A/C Re-New Unpressurized

A/C Re-New, formerly Zerol® Ice, has been used successfully for many years to improve the performance of air conditioning and refrigeration systems. A/C Re-New provides significant saving in energy use. It also quiets noisy systems and extends the life of the system. It is a lubricant that blends with the system’s oil, lasting for the life of the equipment, or until the oil is changed.
A/C Re-New can be used in air conditioning as well as refrigeration applications. It is formulated for use with R-22, R-410A as well as other refrigerants. The 4 oz. package can be used to treat systems up to 5 tons. For large commercial systems, such as packaged units or larger refrigeration systems, multiple bottles should be used. Additionally, the product is available in 32 oz. quarts. Install with the A/C Re-New Injector.
A/C Re-New Connect Inject is a quick, one-time disposable injector option for introducing A/C Re-New into the air conditioning system where the vessel is pre-charged with 4 fluid ounces of treatment. Although not required, the use of the reusable Connect Injector Tool (part no. 4155-01) is recommended. One device up to 5 ton system capacity; use multiple injectors for larger systems.
