Nu-Calgon 4127-75 Blackhawk (18 ounce can)
Blackhawk is an expanding foam, non-fragrance coil cleaner for HVAC/R applications. The product’s expanding foam permeates deep within the coil then liquefies to quickly remove grease, grime, and other oily surfaces. Blackhawk’s heavy-duty formulation is powerful, yet safe and problem-free in food processing areas – produces no objectionable fumes.
Blackhawk is a specially formulated expanding foam evaporator and condenser coil cleaner that is safe in and around food processing areas. Product can be used as a non-rinse for evaporator applications since the condensate will rinse off the coil. Blackhawk is suitable to clean washable filters, exhaust hoods and other metal surfaces.
Blackhawk can be used to clean coils in window air conditioners, PTAC or field build-up systems where an expanding foam, non-fragrance coil cleaner in an aerosol format is desired.
