Nu-Calgon 4127-75 Blackhawk Coil Cleaner

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.

This product must be used in accordance to the following directions by HVACR professionals only.

• Turn off or disconnect power to unit being serviced.
• Remove any heavy or matted soils that can be easily dislodged by hand.
• Do not spray into electrical components.
• Shake well before using. Remove cap and point toward surface to be cleaned.

Condensers:
Inject cleaner into the coil. Blackhawk’s expanding foam will penetrate throughout the coil. Wait a few minutes for foam to liquefy and remove grease and grime within coil. Rinse with water. For stubborn or heavy deposits, repeat applications may be necessary.

Evaporators:
Introduce cleaner into coil, it is not necessary to rinse — the condensate will rinse the coil.
