Description

ACC Plus is a powerful cleaning agent for cleaning of diesel

engine air coolers, scavenging air systems and the compressor

side of turbochargers. ACC Plus is a microemulsion type cleaner,

where a synergistic blend of biodegradable surfactants and low

toxicity solvents replace the use of the harmful solvents

traditionally used in air cooler cleaners without reducing the

cleaning performance. It is formulated to meet the latest

environmental standards, and is non toxic both to the environment

and to persons handling it. ACC Plus contains no chlorinated or

aromatic hydrocarbon solvents, nonylphenol ethoxylates or other

substances harmful to the environment.

Features

• Meets the latest environmental standards

• Equal cleaning performance to traditional cleaners based

on harmful chlorinated solvents

• Low toxicity, low evaporation and pleasant smell

• Formulated to remove oil, grease and carbon deposits from

air coolers and scavenging systems

• Maintains, stabilises and maximises air cooler efficiency

• Leaves no residue and has no harmful effect on engine.

• Can be used for handspray cleaning while diesel engine is

stationary

• Ideal for use in soak bath or cleaning tanks, such as the

Chemical Cleaning Unit and the Ultrasonic Bath

Benefits

• Efficient and economical

Directions for use

Recirculation method in-situ

For this cleaning procedure the engine needs to be stopped and secured. Permanently installed spray nozzles in

combination with a cleaning solution tank and pump, such as the Unitor Chemical Cleaning Unit should be used. It is

advised to blind off the cooler outlet. Properly mix water and 10-30% ACC Plus, depending on the severity of the

contamination, in the tank. Connect the pump's outlet to the nozzle assembly and the air cooler drain to the tank.

Start the pump and spray the solution through the nozzles over the entire surface of the cooler and drain back to the

tank. Circulate the solution for a period of 1 to 6 hours. After cleaning, rinse with fresh water. Remove the outlet blind

and disconnect the pump and tank loop.

Soaking method in-situ

For this cleaning procedure the engine needs to be stopped and secured. Blind off the cooler outlet and flood the

cooler with a solution of 10-30% ACC Plus in water depending on the severity of the contamination. Soak for a

period of 1 to 6 hours and drain to slop tank. Agitation by means of steam or compressed air will improve the

cleaning effect. After cleaning, rinse with fresh water. Remove outlet blind and close drain.

Out of Service Cleaning:

Soak bath method

Remove the cooler from the engine and place in a soak bath filled with a solution of 10-30% ACC Plus in water for a

period of 1-6 hours. Agitation by means of steam or compressed air will improve the cleaning effect. After cleaning

rinse with fresh water and reinstall the cooler. This method is also suitable for machine parts with stubborn carbon

deposits.

Hand spray method

For this cleaning procedure the engine needs to be stopped and secured. Open the inspection cover on top of the

cooler and the drain valve. Spray undiluted ACC Plus into the tube nest, with e.g. a Unitor Jet Spray Unit, and allow

to penetrate into the deposits for a minimum of 1 hour. Rinse thoroughly with a high pressure jet such as a Unitor

High Pressure Machine. Close inspection cover and drain.

In-service cleaning

The general principle is to inject a solution of ACC Plus into the air trunking upstream of the charge air cooler

followed by a clean water rinse. For efficient cleaning of air coolers, it is necessary to use correctly installed dosing

and injection equipment. To calculate the amount of solution required to clean an air cooler, calculate or find the

cross-sectional area of the cooler and use 3 litres of cleaning solution per square metre or as table below:

Engine HP Solution mix. with 25% ACC Plus

6,000 to 12,000 3 litre mix

12,000 to 24,000 4.5 litre mix

24,000 or more 6 litre mix

For in-service cleaning of air coolers and the air-side of turbochargers, a solution of 25% ACC Plus in freshwater is

recommended.

The appropriate dosage of cleaner is then placed in the dosing pot and injected up stream of the air cooler for a

period of 10 minutes. After a further 10 minutes, a similar quantity of fresh water is injected to rinse off the emulsified

deposits. Rate and frequency of application depends mainly on the condition of the air coolers. However when

starting with the use of ACC Plus, recommended injection is every 24 hours. After the initial cleaning period, the

cleaning effect should last for 48 hours of operational time. Although frequency of cleaning may vary, the calculated

cleaning dose should remain the same. This cleaning method is only recommended if approved by the engine

manufacturer!
