Application :

GENERAL MAINTENANCE: NOVACHEM HCF ECO is universally applied to clean ship decks, floors, walls, etc.
IMMERSION BATH: NOVACHEM HCF ECO is applied undiluted in immersion baths to clean galvanized parts or objects made of aluminium or zinc.
SPRAYING: NOVACHEM HCF ECO can be sprayed pure or diluted with water.

TANK CLEANING:
1. NOVACHEM HCF ECO is applied in aluminium tanks and in tanks with a zinc silicate coating.
It is applicable on epoxy coatings if the concentration is maximum 10% and the temperature maximum 60°C.
2. NOVACHEM HCF ECO is also applied as a last treatment after hydrocarbon-free cleanings where an emulsifying cleaning agent has been used. 3. If NOVACHEM HCF ECO has been used for hydrocarbon-free cleaning, NOVACHEM HCF ECO should be used afterwards in those cases where the next cargo is going to be methanol, etc.

Directions for use :

GENERAL MAINTENANCE: Moisturize the surfaces that are to be cleaned with the undiluted product and allow the product to work for 20 – 60 minutes. Brush meanwhile and rinse thoroughly with water afterwards.
IMMERSION BATH: Allow the product (pure, 50 – 60°C) several hours working time after placing the objects in the bath. Take them out, brush and spray off with a powerful highpressure water jet.
SPRAYING: Depending on the amount and characteristics of the contamination, NOVACHEM HCF ECO is used pure or diluted at temperatures from 20 – 60°C. Allow the product to work for 20 – 60 minutes and spray afterwards with a powerful water jet (warm water).
PRE-WASHING: Prior to tank cleaning with NOVACHEM HCF ECO, it is advised to pre-wash with hot water (± 60°C). In case of drying or semi-drying oils, pre-washing is to be done with cold water.
RECIRCULATION: With this method, cleaning chemicals are to be added in a separate tank to a previous determined amount of water. The required amount of cleaning chemicals is usually 1% of the capacity of the tank that is to be cleaned. Heat the water with a spiral in the tanks. The tanks are washed by means of a cargo pump, after which the used solution is brought back into the mixing tank. With one solution, usually 2 to 3 tanks can be washed, after which a new fresh solution should be made. NOVACHEM HCF ECO is, depending on the amount and character of the contamination, circulated 2 – 6 hours in a 5% solution. Optimal cleaning is best done at 20 – 80°C.
SPRAYING: Spray the tank sides with pure NOVACHEM HCF ECO until they are properly moisturized. Allow the product to work for at least 30 minutes. After this each tank compartment is to be rinsed with water (60°C) during 45 minutes.
DIRECT INJECTION: Inject directly 2 ltrs of NOVACHEM HCF ECO per every 100 ltrs washing water in the tank system. The advised cleaning temperature lies in between 20 – 60°C. The cleaning takes 2 – 6 hours. Rinse thoroughly with water.
HYDROCARBON-FREE CLEANING: After cleaning with NOVACHEM HCF ECO rinse with fresh hot water (70°C).
