Anti-calcium scale application
Major chemical Co. factory in Japan

Comparing two heat exchangers

Heat exchanger #2 with Non-Scalor

In general, the growth of calcium scale inside heat exchangers affects their heat exchanger efficiency and even disrupts factory operation in the worst-case scenario.
To protect multi-pipe heat exchangers from calcium scale issues, Major Chemical Co. Ohita factory ran a test trial of Non-Scalor.
First, the factory implemented regular cleaning on two heat exchangers and installed Non-Scalor on one of them on Aug. 2000, and then confirmed the device’s performance six months later.
In Feb. 2001, no calcium scale adhesion was seen on the one equipped with Non-Scalor, while the other without Non-Scalor had a mass amount of calcium scale being built up again.
There will no longer be a decrease in the heat exchange efficiency or disruption on the factory’s product lines.
