In Western China, fall 2002:

Evans NPG+ Unlocks Reserve Cooling System Capacity at 16,000 Feet.

In the fall of 2002 Qiang Xu, President of Shanghai Evans Auto Coolant Sales, Ltd., Shanghai, China, learned that a railway construction project in the high mountains of western China was being delayed because the construction equipment was overheating. To cope, the equipment was being loaded to only 50 percent of capacity and periodic shut-downs were scheduled to prevent boiling over. A three year project was going to take five years. Xu saw his chance to dramatically prove that switching to Evans NPG+ waterless engine coolant could solve all of their problems.

Shanghai Evans is the exclusive agent for China of Evans Cooling Systems, Inc. of Sharon, CT. Xu, along with a supply of 24 gallons of Evans NPG+, flew from Shanghai to western China, landing at the city of Germu in the province of Qinghai. At Germu he contracted with a taxi driver for three days of services. The distance from Germu to the construction site, located on the far side of the Kunlun Mountains, was about 100 miles. The route was over the Qing Zang Gong Lu, a difficult road that is also the pathway to Tibet. The elevation at the construction site is about 16,000 feet.

The taxi was a 1.8 liter Volkswagon Santana with 200,000 km on the odometer. Along the trek at a steep section the car lost power and driver announced that they would now stop to cool off the engine. Xu said, “No, we aren’t going to do it that way.” Xu explained that he would make the car over-heat proof. He drained out the existing coolant and then sacrificed a gallon of NPG+ to remove the remaining water. He re-filled with 2 gallons of NPG+.

The owner-driver was amazed at the increased power from the engine and the fact that the cooling system was not boiling over. He had not believed Xu that a mere change of coolant could make any difference.

There were some very bad sections of the road that were under construction. Jeeps could take a short cut across sand desert around a particular construction section. Xu told the driver to follow the Jeep path. “I cannot go there in my Santana, it will break down,” the driver replied. Xu said, “You have Evans, just go.” Along they went without incident, even passing a Jeep.

Finally arriving at the construction site, Xu proposed a demonstration of Evans NPG+ on some of the overheating-prone equipment. The men at the site were skeptical that a change of coolants could matter. Although their equipment could be used only half-loaded and required periodic cool-down time, it was a tough sell for Xu. A van in poor condition was offered for a test but Xu rejected it. He pointed to a dump truck in decent condition and said, “I want to convert that one.” They asked, “Why should we trust you?” “Xu replied, “I have come 4,000 km to demonstrate and what I have works.” At that point the taxi driver attested that in his car the power increased and the boiling stopped. After more questions from 7 people, including engineers, approval was given.

The dump truck, rated to carry 14 metric tons at sea level, could carry only 7 metric tons at 16,000 feet. Xu converted the truck to Evans NPG+. By the time he was finished it was getting late. He left these instructions: “Tomorrow, overload the truck to 15 metric tons and use it that way all day long.” Xu and the taxi driver went back to Germu for the night.

The next day Xu returned to find that no overheating or boiling had occurred. His reception was practically a hero’s welcome. As the dump truck drivers got paid according to the tons moved each day, the driver of the converted truck was delighted by his good fortune. Xu was invited to convert a second truck.

The second truck was successfully converted with the same result. The bosses at the construction site said that they still couldn’t understand how a coolant change could produce such dramatic results but since they had seen it with their own eyes, they were believers. They asked Xu to convert the rest of their equipment. He couldn’t because by then his supplies were depleted. Xu left with their statement attesting that NPG+ had solved the problems of overheating at high altitude and that it was no longer necessary to run their equipment less than fully loaded. Evans NPG+ had tapped the reserve capacity that exists in all liquid cooling systems (but which is unavailable when the coolant is water-based).

The taxi man, skeptic turned believer, has bid to be the Qinghai province distributor for Evans NPG+.

Evans in China. The Associated Press recently reported that China’s economic growth rate is expected to be 8 percent this year. Evans is there, making NPG+ available to its Chinese customers. Even if you don’t read Chinese feel free to browse our Chinese web pages.
