"Down Time"

40 to 50 percent of engine wear, malfunction and catastrophic failure start internally in the cooling system.

(Reference: Caterpillar and Cummins Inc, leading engine manufacturers)

This is due to undetected and undetectable contamination resulting from spent additives (SCA's), Glycol film, spent coolant and foreign particles causing extreme localised overheating known as hot-spots. These do not show on the temperature gauge, damaging oil viscosity and altering critical clearances resulting in premature wear, malfunction and engine failure.

This occurs in all types of engine, including the modern and well maintained and results in major downtime and operational expense.

Keeping the entire internal cooling system in pristine condition by rapid power flushing and purge of the cylinder head, block, radiator and heater cores and reinstating with fresh coolant every two years. Every year is recommended in extreme operating environments. Engine manufacturers require cooling systems to be flushed.

PCS PulseFLush FL100 Machine incorporating the superior and leading technology of Advanced Pulsating Hydro pneumatics.

For engine preventative maintenance service significantly reducing and eliminating entirely the above percentage of engine wear, malfunction, downtime and catastrophic failure.

With the high demands placed on modern engines and equipment, mechanical workshops can now provide the most up to date technology in this field, the FL100 Pulse Flush service, achieving excellent results in cooling system maintenance not previously obtainable.

The FL100 Pulse Flush is a Best Practice engine service.

Army Report: FL100 Pulse Flush Engine Service Tests.

Two Army generators were run up to full continuous operating temperature at 80% load.

"Before" temperatures was measured externally using Infra-red digital equipment at marked locations. The engines were then shut down and serviced with the FL100 Pulse Flush Machine.

On completion the generators were again run up to full continuous operating temperature at 80% load for the same period of time. "After" temperatures were then taken at the same locations. This recorded a big reduction in engine operating temperature.
