Application

Immersion bath: Dependant on design, the cooler is flooded with AIR COOLER CLEANER immersed in a tank full of product. The product should be heated to approx. 50°C and agitation provided with an air line. After 2 hours, drain off and flush well with water, followed by drying with an air line.
Circulation method: Some designs of cooler can be circulated “in situ”. In this case a pump tank and pipe system is fitted permanently or connections are provided for connecting a temporary circuit. The system should be filled with AIR COOLER CLEANER circulation carried out for 2 – 4 hours at a temperature of upto 50°C.
After cleaning the cooler should be thoroughly flushed with fresh water and dried with an air line.

Direct injection

AIR COOLER CLEANER has the approval of the majority of major manufacturers for use either in their own design of “in service” cleaning system or other recognised systems provided by suppliers.
Injection systems: StarMarine offer a range of newly developed easy to operate manual systems.

Directions for use

Regardless of the type of “in service” system used, AIR COOLER CLEANER should be dosed at the ratio of 2 parts water added to 1 part product (in that order) and well mixed for immediate use. If the emulsion is left standing for up to 5 minutes its composition will change and effectiveness reduced. It is most important that 5 – 10 minutes after dosing the solution, injection with fresh water only is repeated using double the total volume of the first solution to flush off the chemical residual which contains the “solved” contamination. Failure to do this will result in a “sticky cooler” which will foul very quickly.

Turbo blowers: The water washing of the air side of turbo blowers has been accepted for many years. Most manufacturers provide nozzles and dosing pots to inject water into the volute casing after the inlet filters. These systems can be utilised with a solution of AIR COOLER CLEANER at the same ratio of 2 parts water mixed into 1 part product and dosed via the water wash system.
