Third Party Testing

Third Party Testing 2018-01-14T05:04:03+00:00

Three independent labs have tested Cool Technologies’ heat pipe architecture. Other tests have been conducted by electric motor manufacturers. None of our technologies have ever failed a third party test.

Test 1

In 2007, Essco Pumps & Controls, a member of the Hydraulic Institute, conducted the tests in accordance with standards set forth by the Institute. Essco assembled typical submersible motors: one standard submersible and one incorporating our technology.

Two tests were performed. The first was a back-to-back comparison with each operated in a dry-pit mode. The results: the standard submersible operated at full load for 15 minutes before it reached a Class F temperature and overheated. The Cool Technologies’ motor operated for 100 minutes before reaching Class F temperature.

The second test validated the heat removal capabilities of Cool Tech’s heat pipe architecture. By circulating a small amount of water (1/3 gpm) through the oil chamber, Cool Tech’s motor operated continuously without ever reaching Class F temperature.

What it means

With our technology, one design can do it all. A single motor rating can function in dry-pit, submersible and explosion-proof applications. Current pump manufacturing practice calls for a separate rating for each application.

Test 2

On December 6, 2013, ESSCO Pumps and Controls conducted a second test—the time using a dry pit submersible pump — with even better results.

Dry pit submersible pumps are commonly used in national, state and municipal waste water utilities worldwide as well as in the mining, dredging and oil drilling industries.

The tests examined the tolerances of an industrial electric motor in an extreme situation. The tolerances determine the amount of power that can be driven through pumps run by the motor and are a strong predictor of the maintenance and other service downtime the pump will require. The original pump motor was rated to run, without submersion, for up to 15 minutes before the pump’s protective circuits will turn it off to prevent overheating. This heat limitation restricts the output of the motor.

The test pump used the same industrial electric motor, except with our thermal dispersion technology incorporated. The result: the test pump ran without submersion for more than two hours at or above full power without reaching critical temperatures that would have caused an automatic shutdown.

What it means

The tests confirmed the company’s belief that our heat pipe cooling system equals the effectiveness of a more complex water-cooled system. Therefore, simple designs incorporating our thermal technology combined with the proven increase in potential output should result in lower costs to manufacture by reducing the amount of material needed to produce a pump or electric motor with a specific output.

Test 3

On December 13, 2013, Mohler Technology, Inc. of Boonville, Indiana tested an alternator enhanced with our technology. A 650kVA alternator (generator) was run at full load to test its operational limits. The heat produced by generators of that size must be removed or controlled in order for the alternator to operate effectively. Manufacturers’ current best practice is to add either a liquid cooling system or an extra large frame around the motor to provide additional surface area to help dissipate the heat. Both practices increase the cost and complexity of the generators.

650 kVA generators are commonly used in the mining, telecom, water treatment and oil and gas industries as well as used to provide back-up power for heavy industry, data centers and healthcare facilities.

The alternator tested used our thermal technology with no other cooling of any kind. The results showed a minimum of 25% improvement in power density over the manufacturer’s rating for the alternator when operated without water cooling. In fact, the alternator achieved power densities comparable to a liquid-cooled or over-framed one.

What it means

Once again, the tests confirmed our belief that our heat pipe cooling system equals the effectiveness of a more complex water-cooled system. Because motors equipped with our technology deliver more horsepower than any other motor of the same frame, designers now have flexibility. They can lower costs by using smaller pump or motor designs or they can deliver enhanced performance from their existing motor frames.
