Nu-calgon NUCAL-7537-05 Corrosion Inhibitor 5 Gal Pail

Product Description

The NU-CALGON NUCAL-7537-05 is a liquid corrosion inhibitor and lubricant film treatment designed to protect metal surfaces in recirculating fluid systems. Supplied in a 5-gallon pail, this red-colored liquid forms a protective film on internal metal components to reduce oxidation and extend system service life. It is rated for operating temperatures up to 185 degrees F, making it suitable for a range of hydronic and process recirculating applications. Licensed HVAC technicians and plumbing professionals typically apply this product as part of a system treatment or startup procedure.

This corrosion inhibitor is intended for use in recirculating systems where ongoing metal protection is required. Typical applications include closed-loop hydronic heating and cooling systems, chilled water loops, and similar fluid-handling circuits where ferrous and non-ferrous metals are present. The 5-gallon pail format suits service contractors and mechanical shops that treat multiple systems or require bulk supply for larger installations.
