Nu-calgon NUCAL-4291-18 Aerosol Coil Cleaner 18 Oz

Product Description

The NU-CALGON NUCAL-4291-18 is an alkaline-based aerosol coil cleaner formulated for use on air-cooled condenser coils and commercial kitchen equipment subject to heavy grease buildup. The cleaner dispenses as a foaming spray that clings to coil surfaces, penetrating and lifting grease, dirt, and debris without the need for prolonged scrubbing. At 18 oz per can, it is sized for field service calls and preventive maintenance visits. The biodegradable formula carries USDA authorization, making it appropriate for use in food-service environments where chemical compliance is required. HVAC technicians and refrigeration service pros reach for this product as a fast-acting coil-cleaning solution that restores airflow and system efficiency.

This product is suited for residential and light commercial HVAC applications as well as commercial kitchen environments. It is commonly used on small air-cooled condenser coils that have accumulated dirt and grease over a service season. The aerosol format makes it practical for rooftop units, condensing unit service, and kitchen exhaust equipment where access is tight and portability matters. It is applied during routine preventive maintenance or when elevated head pressure or reduced cooling capacity signals restricted airflow across the coil.
