Nu-Calgon 4168-08 Evap Pow'r® Coil Cleaner

Evap Pow’r is a “no-rinse” product formulated for cleaning indoor evaporator coils. The green-colored, slightly alkaline liquid is metal-safe and therefore will not harm the coil’s metal surfaces when left in contact with them even in a no-rinse application. It cleans and emulsifies the most stubborn soils and deposits, and is biodegradable as well as USDA-Authorized.

This is the highly concentrated version of the product and it should be diluted with water at a 3:1 ratio.

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

• Turn off equipment and access evaporator coil.
• If the coil is heavily soiled with lint, dirt, etc., use a brush to remove as much as possible prior to cleaning.
• When using Evap Pow’r-C, prepare a cleaning solution in one of the quality Nu-Calgon sprayers, mixing one part of Evap Pow’r-C with three parts of water.
• Be sure nearby registers are closed. Although the blower was turned off, natural air currents could pick up and entrain droplets of cleaning solution and this should be controlled.
• Spray cleaning solution onto coils, being sure to lightly coat all surfaces.
• Rinsing is not required, particularly where there is sufficient humidity being condensed from the ambient air to provide a flushing or rinsing action. Return system to service.
• If rinsing is done, take the opportunity to treat coil with Cal-Shield® surface protectant (4148-08).
