## Overview

Nu-Calgon 4127-75 Blackhawk Expanding Foam Coil Cleaner is an 18 oz aerosol cleaner designed for HVAC/R coils and metal surfaces. Its heavy-duty, non-fragrance expanding foam penetrates deep to dissolve grease and grime quickly, while being safe for use in food processing environments. The product requires no rinsing on evaporator coils, as condensate naturally washes away residue, making it a professional-grade, efficient solution for maintaining clean, odor-free air conditioning and heating units.

## Description

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.

### ⭐⭐⭐⭐⭐ Used to clean scotsman commercial ice machine coil
*by B***. on September 5, 2019*

Bought this to clean coil in Scotsman Commercial Ice Machine. First, it's a hard part to reach and clean. But this stuff has a nice stream and we were able to clean most of not all of the radiator. Second, the gunk just disappears when using this stuff. No scrubbing. Didnt even wipe. Just sprayed it and let it work. Highly recommend.
