Nu-Calgon's A/C ReNew is a specially formulated treatment with years of proven field history in enhancing the performance of air conditioning and heat pump systems. Reduces energy consumption - lowers starting and running amps. Improves heat transfer in evaporators. Great for new and old R-22 and R-410A systems. A/C ReNew is an established treatment for residential air conditioning systems, particularly older systems where performance may have diminished over the years. Extensive testing of the technology in actual installations has shown its ability to lower energy consumption on average by 11%. The same testing revealed noise reduction and improved cooling performance. A/C Re-New, formerly Zerol® Ice, has been used successfully for many years to improve the performance of air conditioning and refrigeration systems.
