Nu-Calgon - TriClean 2x is specially formulated in an easy-to-use packaging for the annual cleaning of residential and light commercial outdoor air conditioning coils. The metal safe, low-foaming biodegradable formula rapidly emulsifies dirt and grime so the system continues to run efficiently, lowering operating costs and increasing system longevity. The product can safely be used on coated and non-coated fin or microchannel designed coils. The concentrated formula is tailored to its integrated sprayer packaging, saving time duiring sprayer preparation/clean-up and lowering the cost of sprayer maintenance from usage wear. Each container is capable of cleaning three 5-ton coils, making its use cost effective. The packaging provides the convenience historically sought by technicians who sprayed coils ineffectively with only water.
