HVAC Professional’s Concentrate Formula: Our team of HVAC field professionals designed this heavy-duty coil cleaner for use on our toughest maintenance jobs. Supplied as a concentrate, one gallon of Blue Blaster can be diluted with water 3:1 to make 4 gallons of serious coil cleaner. For Air Cooled Condenser Coils (Outdoor Units): This product is intended only for outdoor use with air cooled condenser coils. It is not recommended for use on indoor units, coated fins, or micro-channel coils. Compatible equipment includes condensers of central air conditioners, ductless mini-splits, packaged units, commercial refrigerators, and more. Sav Correct Dilution Ratios for Coil Cleaning: The Coil Cannon has dilution ratios of 3:1, 4:1, 6:1, 9:1, and 10:1 and has been designed specifically for use with HVAC coil cleaning chemicals. These are the ratios commonly found in all top brand chemical coil cleaners. Automatic Chemical Mixing and Foaming: Simply pour the concentrated chemical into the bottle, dial in the desired ratio, and the water from the hose will automatically mix with the chemical and spray out at the correct proportion. Save time and the complication of manually diluting with water. The foaming wand can also be used to enhance the foaming action of your chemicals. Large Mouth and Large Volume 2-Quart Bottle: The large bottle mouth makes it easier to pour in concentrated chemicals without spilling. The large 2 quart volume allows you to clean longer without having to stop and refill as often. Compatible With All Cleaning Chemicals: The Coil Cannon is compatible with all coil cleaners and cleaning chemicals. Acidic (low pH), basic (high pH), detergents, and disinfectants can all be used.
