DESCRIPTION

SPECIAL STEP No1 is a solvent - based concentrate emulsifier specially formulated for cleaning boilers, engine cooling systems and heat exchanging surfaces that are fully contaminated with fuel or lubricating oil.

 

APPLICATION

SPECIAL STEP No1 is mainly used to clean boilers and cooling water systems. It is also used for cleaning heat exchangers, condensers, deep tanks and bilges from heavy oil contamination.

 

USE AND DOSING

Boiler Cleaning

Oil deposits can be removed from boilers by circulating a 5-10% solution of SPECIAL STEP No1. For best results, the cleaning solution should be heated to 50-60oC and temperature should be maintained throughout the cleaning procedure.

All cleaning should be done off-line.

1. Locate contamination source, determine contamination level and adjust prior to starting the cleaning operation.

2. Induct the required amounts of SPECIAL STEP No1 and water simultaneously, through the steam drum manhole. For light contamination, use a 4-5% solution, whereas for heavier contamination use a 7-10% solution.

3. Secure steam drum manhole and open air vent valves at the top of steam drum.

4. Fire boiler for a few minutes and secure for 15-20 minutes. Repeat until water reaches a temperature of 50-60oC. Maintain this temperature for approximately 12 hours by periodically firing the boiler to promote agitation and solution circulation thus increased efficiency.

5. Drain boiler and open all drain valves and manholes.

6. Rinse drums, tubes and headers with water using a high-pressure hose.

7. Secure all openings and refill boiler.

8. For one week after boiler re-operation, we recommend you add 2.5 liters of SPECIAL STEP No1 in the boiler water every 12 hours to ensure all oil contamination is effectively removed.

 

Engine Cooling Water Systems Cleaning

The oily deposits in engine cooling water systems may be removed by draining the cooling water and refilling with a solution of SPECIAL STEP No1 in fresh water. This solution, when circulated, will emulsify oils and provoke their removal.

1. Drain the cooling water system and refill with fresh water. Having the engine stopped, recirculate and heat until temperature reaches 60oC.

2. Add 5-7 liters of SPECIAL STEP No1 per 100 liters of water and recirculate for at least 6 hours.

3. Drain the system and refill with a solution of 5 liters per 100 liters of cooling water at ambient temperatures.

4. Recirculate for another 1-2 hours, then drain the system and repeat the procedure if required.

5. If scale persists, use SCALE REMOVER LIQUID or SCALE REMOVER POWDER for descaling.
