The NUCALGON 4371-92 is an ultra-concentrate alkaline coil cleaner, degreaser, and deodorizer formulated for HVAC service applications. It is based on positive emulsion technology, which converts greasy deposits into a liquid form that can be flushed from equipment surfaces. The formula contains surfactants to wet greasy buildup and corrosion inhibitors to protect metal surfaces during cleaning. It is non-acid, non-toxic, and biodegradable, making it suitable for use in occupied and commercial spaces. The 1-quart ultra-concentrate format reduces storage footprint and is easier to transport on a service vehicle. Licensed HVAC technicians and refrigeration mechanics are the primary installers and service professionals who use this product.
The 4371-92 is designed for cleaning air-cooled condensers, evaporator coils, microchannel coils, permanent filters, fan blades, and motors. Its alkaline, emulsion-based formula is suitable for any coil design. For evaporator coil applications, the product can be used as a no-rinse cleaner per label instructions in situations where sufficient condensate flow will self-rinse the coil. It also functions as a deodorizer, making it useful for units where biological growth or odors are present. General HVAC maintenance and coil cleaning calls are the typical service scenario for this product.
Suitable for any coil design, including microchannel and standard fin-and-tube coils. Designed for use on air-cooled condensers, evaporator coils, permanent filters, fan blades, and motors across residential and commercial HVAC equipment.
Power down the unit and disconnect electrical supply before applying any coil cleaner to HVAC equipment. Follow label dilution instructions for the specific application, as concentrate ratios differ between condenser and evaporator use. For no-rinse evaporator applications, confirm that condensate drainage is functioning properly to ensure adequate self-rinsing per product instructions. Dispose of rinse water and cleaning solution in accordance with local regulations.
