NC KleenBrite is the cleaner of choice for air-cooled condensers. Unfiltered air is drawn through the tube and fine surfaces depositing on them airborne debris like lint, leaves, grass, feathers and insects. If the coil is not cleaned the efficiency of the unit will be adversely affected. The dirt coating could also bake on, making it difficult to remove. If the coil is regularly treated with NC KleenBrite it’s heavy foaming action cleans these contaminants away.
