Nu-Calgon - 4057-56 - A/C Re-New Connect Inject, (Formely Zerol)

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 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.
