Use the following procedure to clean incrustation, scaling, and sediment.Clean the gaskets by using one of the following solvents:
Nitric acid
Sulfamic acid
Citric acid
Phosphoric acid
Complexing agents EDTA and/or NTA
Sodium polyphosphates
Mix the solvent with water. Use a maximum concentration of 0.15 Liters (5 ounces) for every 3.8 Liters (1 gallon) of water.
Heat the cleaning solution to a maximum temperature of 60 °C (140 °F).
Use running water and a brush with soft bristles for cleaning debris. Pressurized water at a maximum of 275 kPa (40 psi) may be used.Avoid damaging the gasket.Use the following procedure to clean biological growth (slime).Clean the gaskets by using one of the following solvents:
Sodium hydroxide
Sodium carbonate
Mix the solvent with water. Use a maximum concentration of 0.15 Liters (5 ounces) for every 3.8 Liters (1 gallon).
Heat the cleaning solution to a maximum temperature of 80 °C (176 °F).
Use running water and a brush with soft bristles for cleaning debris. Pressurized water at a maximum of 275 kPa (40 psi) may be used.Avoid damaging the gasket.Use the following procedure to clean deposits of oil from the plates.Clean the gaskets by using one of the following solvents:
Paraffinic based solvent
Naphtha based solvent
Use a brush with soft bristles and paraffinic or naphtha based solvents (kerosene) in order to clean deposits of oil. Use the solvent at full strength.Avoid damaging the gasket.Note: Do not allow paraffinic or naphtha based solvents (kerosene) to remain in contact with the gaskets for more than 30 minutes. Contact with this cleaning solvent must be limited to 30 minutes or less in order to prevent swelling of the rubber gasket.Do not use solvents that contain the following:
Ketones (acetone, methylketone, or methylisobutyketone)
Esters (ethylacetate or butylacetate)
Halogenated hydrocarbons (chlorothene, carbon tetrachloride, or freons)
Aromatics (benzens, or toluene)Dry the plates with a clean cloth.Closing the Heat Exchanger
