Nozzle selection 10 - Foam nozzle: for cleaning chemicals with foaming properties – generates thick foam. 11 - Standard nozzle: for all other cleaning chemicals – extends the reach of the spray with out foaming. The Standard nozzle can also be used for washing down if needed. 12 - SlipCoat nozzle: for temporary hold coatings – thin and even spray but a very short range, (the Standard nozzle can be used for longer reach).



Chemicals Cleaning procedure

NOTE: Make sure you use personal protection equipment at all times when handling various chemical handling equipment.

Step 1 – Dry cleaning

When cleaning after dry cargo such as cement or coal, it is recommended to sweep and muck out as much residue as possible before any liquids are used.

Step 2 – Pre washing

• Assemble the Tornado 3 Cleaning Jet
• Turn on the water and air flow.
• Open the ball valve on the barrel, and start flushing from the tank top and move the water jet in a sweeping pattern upwards.
• When the top is reached, move the cleaning jet to a new location and repeat.
• Continue until the whole hold is rinsed.

Step 3 – Cleaning with chemicals

• Assemble the Chemical Applicator 150 & Long Reach Lance.
• Attach the Foam nozzle to the Lance (recommended for foaming chemicals).
• With the discharge valve closed, open the filling valve and the overflow valve.
• Fill the tank with water up to the overflow valve (until the water starts to flow out of the valve).
• Close the overflow valve and add chemicals according to recommendation.
• Close the filling valve.
• Open the air inlet valve on the tank.
• Check the air pressure on the pressure gauge on top of the tank.
• When the pressure has reached 5 bar, open the chemical outlet valve.
• Gradually open the air and chemical valve on the lance, adjust both in order to obtain optimal range and foam thickness.
• Apply chemicals from the tank top and upwards in a sweeping pattern until a section is covered.
• Repeat until hold is covered. Depending on chemical used, the temperature and moisture conditions, the exposure time may vary from 10 min to 2 hours.

NOTE: 2 fillings (50 litre of chemicals) of the Chemical Applicator 150 should cover one side of the cargo hold.

Step 4 – Rinsing of chemical solution

• Assemble the Tornado 3 Cleaning Jet • Turn on the water and air flow. • Open the ball valve on the barrel, and start flushing from the tank top and move the water jet in a sweeping pattern upwards. • When the top is reached, move the cleaning jet to a new location and repeat. • Continue until the hold is rinsed.

Step 5 – Application of temporary hold coating

• Make sure that the cargo hold is clean and dry before applying Slip-Coat.
• Assemble the Chemical Applicator 150 & Long Reach Lance
• Attach the SlipCoat nozzle to the Lance
• With the discharge valve closed, open the filling valve.
• Fill the tank with 125 litres of SlipCoat

NOTE: Slip-Coat is a “ready to use product and must not be mixed with water or diluted.

• Close the filling valve.
• Open the air supply to the tank, and the air inlet valve on the tank.
• Check the air pressure on the pressure gauge on top of the tank.
• When the pressure has reached 5 bar, open the chemical outlet valve at the bottom of the tank.
• Open the chemical valve on the lance

NOTE: the air valve on the lance is not to be used in this application.

• Apply Slip-Coat from the top and downwards in a sweeping pattern until a section is covered.
• As soon as the surface appears wet, a proper film is created.
• In order to keep the drying time to a minimum avoid thick layers. One litre of Slip-Coat covers 15-20m2
• Repeat until hold is covered.
NOTE: apply the hold coating in as thin layer as possible.
• Depending on the temperature and humidity, the drying time may vary from 10 min to 2 hours. Allow the film to dry completely before loading the cargo.

Step 6 – Rinsing of equipment

• Disconnect the ¾” Air supply hose from the Chemical applicator 150.
• Disconnect the ½” Air supply hose from the Lance.
• Close the Chemical outlet ball valve.
• Fill the Chemical applicator 150 with FRESH water all the way to the top.
• Open the Chemical outlet valve and flush the Chemical delivery hose and the Lance as well as all nozzles that have been used.
