NOVACHEM Air Cooler Cleaner (NACC) is a liquid blend of highly active cleaning and corrosion inhibiting compounds. Nova’s ACC has been developed for safe, fast and economical in service cleaning of the air handling systems of turbo charged diesel engines.

By using Nova’s ACC, air borne contaminants which have been carried into and deposited on scavenger air trunks, air coolers and inlet valves are removed. Thus, all surfaces are kept clean and free of deposits.

Advantages :

1. By using Nova’s ACC fouling of air coolers is reduced thus heat transfer and engine efficiency is improved. Pressure drop across the air cooler and air temperature after the air cooler are kept to a minimum.
2. Fire hazards from the build-up of grease and residue are minimized.
3. Down time and expense of periodic dismantling of the air handling system for cleaning is eliminated.
4. Scavenging efficiency is improved by the reduction of deposit build-up around scavenging ports.
5. Water displacing surfactants incorporated in Nova’s ACC form a mono molecular film throughout the air handling system which protects the metals and reduces the adherence of airborne contaminants.

Usage :

Nova’s ACC is suitable for all types of diesel engines. Nova’s ACC /fresh water mixture has no flash-point and cylinder lubrication is not impaired.

Dosage :

The following table shows our recommendation for initial dosage per air cooler. This is based on one injection every 24 hours. This can be varied based on performance of the pressure drops across the air coolers. The recommended ratio is 1 part of NACC to 3 parts of water.

Application :

Nova’s ACC can be applied by injection, immersion or circulation. For immersion and circulation, cleaning time is reduced considerably by heating the chemical to maximum 50C (122F). If the air coolers are very dirty it may be advisable to use NOVA Alkaline Cleaner to thoroughly clean the system before commencing Nova’s ACC treatment.

Immersion Method :

The dismantled parts to be cleaned are laid in a tank specially designed for the purpose, which has been filled with Nova’s ACC. Movement is achieved by means of compressed air. Cleaning time : 5 - 12 hours.

Circulation Method :

The equipment to be cleaned (fuel oil-heater, oil cooler, etc.) is connected to a pump and a tank by means of tubes. Depending on the degree of fouling. Nova’s ACC is circulated through the equipment for 5 - 15 hours.

Handling Instructions :

Precautionary measure - should NACC come in contact with the skin, rinse off with plenty of water, and then rub in any oily cream. Protect the eyes. NACC concentrate actually has a very high flash-point, but should be kept away from open.
