Coil Cleaners for the HVAC/R Industry Why use a coil cleaner? Dirty or blocked coils will result in reduced air flow and poor heat transfer. Equipment could run hotter, reducing its useful lifetime, increasing operating costs and reducing comfort or refrigeration capacity. Properly cleaning the coils will keep equipment running at peak performance. How do coil cleaners really work? The two active ingredients are soap and an acid or alkaline based surface brightener. • The soap’s job is obvious — to break up and carry away dirt and grease. • The surface brightener’s job is also straightforward: Air, moisture and other chemicals will react with aluminum coil surfaces to form layers that can collect dirt and reduce heat transfer. The strong alkaline or acid compounds in the coil cleaner will chemically clean the layers away until bright metal is exposed, returning the coil surface to its original design performance. How can you calculate dilution levels? Concentrated coil cleaners are meant to be diluted with water. Using the concentrate straight from the bottle or strong mixtures on lightly soiled coils can result in damage to the surface being cleaned. • Extremely dirty coils require a higher content of the coil cleaner versus water to get the desired cleaning. Moderately soiled coils can be cleaned with an equal amount of coil cleaner and water content. Slightly soiled coils can be cleaned with a higher water to coil cleaner content to get the desired cleaning. Can coil cleaners be used to clean other surfaces? Indoor coils, cabinets, air filters and fan blades can be cleaned with a diluted concentrate. Each Coil Cleaner has a dilution chart on the bottle as a guideline. What is the difference between types of coil cleaners? They will all clean and treat the surface of the coil. The major differences are: • Acid or Alkaline based (acid for strong surface treatment, alkaline for general brightening) • Formulation • Amount and type of soap • Color National Refrigerants, Inc. 11401 Roosevelt Boulevard Philadelphia, PA 19154 Tel: 800.262.0012 fax: 215.698.7466 web: www.refrigerants.com e-mail: [email protected] Designed to meet the cleaning needs for a variety of applications
