Tea & coffee vending machines conducted a six-month test trial of Non-Scalor to solve the issue of calcium scale that was clogging their water tubes.
Before the trial, the three automats newly replaced their water tubes and washed inside the water tanks connected to the tubes. Then, they installed Non-Scalor on two of the machines to compare the device’s effectiveness against calcium scale in the tubes with and without the scale preventer.
As a result, the ones with Non-Scalor had no calcium scale being built up inside their tubes. On the other hand, calcium scale clogged up more than half of the tube with no Non-Scalor.
Moreover, the two tea/coffee makers with Non-Scalor had a slight calcium scale deposit at the bottom of their water tanks, but the unprotected machine’s water tank had a large calcium scale deposit at the bottom.
Comparison of calcium scale deposit six months after installing Non-Scalor
| Tested vending machines | #1 with Non-Scalor and a filter | #2 with Non-Scalor | #3 without Non-Scalor |
| Inside the tubes | Almost no scale adhesion | Almost no scale adhesion | Over a half of the inside of the plastic tube being clogged with calcium scale |
| Lower water tanks | Small calcium scale deposit seen at the bottom | Small calcium scale deposit seen at the bottom | Larger calcium scale deposit seen at the bottom |
| Upper water takns | No remarkable change | No remarkable change | No remarkable change |
