Nu-calgon 4190-08 Alkaline Coil Cleaner 1 Gallon

Product Description

The NU-CALGON 4190-08 is an alkaline coil cleaner formulated to remove grime and buildup from air cooled condenser coils. It ships as a 1 gallon concentrate with a pH of 9.5, placing it in the moderate alkaline range effective for breaking down greasy surface deposits without the aggressive attack of high-pH caustic cleaners. HVAC technicians use this product during routine maintenance calls and seasonal startup procedures to restore heat transfer efficiency on condenser coils that have accumulated dirt, dust, and organic debris. The green-colored formula provides easy visual confirmation of coverage during application.

This cleaner is intended for use on air cooled condenser coils in residential and light commercial HVAC systems. It is well suited for rooftop units, split system condensers, and packaged equipment where coil surface fouling reduces system efficiency and increases head pressure. Technicians applying this product as part of a scheduled preventive maintenance program will find the concentrate format practical for fieldwork where dilution ratios can be adjusted to match soil load.
