Evap Pow’r is a no-rinse, biodegradable cleaner for indoor evaporator coils. This slightly alkaline, green liquid is safe for metal surfaces and effectively emulsifies tough soils and deposits. NSF A1/K4 registered, it’s also suitable for use in food processing environments. The ultra-concentrate version of Evap Pow’r requires a 3:1 water dilution, providing heavy-duty cleaning power in a compact form that reduces storage space and weight by 75%—ideal for transport. It can be used with Nu-Calgon’s Coil Gun at a 10:1 (setting E) dilution for convenience.
