QC-1 Freezing Point Adjustment

The following formula is a guide to the amount of solution to drain and the number of gallons of QC-1 to add to a system to change the freezing point.

QC-1 Industrial Coolant Required
 = System capacity X (desired % concentration - present % concentration)
100% - present percent concentration

For Instance: If the system capacity is 1,000 gallons and the resent concentration is 30%, and the desired concentration is 50%, then substituting these numbers into the above formula, we have:
QC-1 Industrial Coolant Required
=1,000 (50-30) =20,000 = 286 Gallons
      100 - 30              70

 We also offer  specially formulated glycol-based products that protect circulating systems of large stationary engines, line heaters, and other water-cooled equipment from destructive corrosion, cavitation, and water freeze-up.

This is also the amount of solution that must be removed from the system to accommodate the QC-1 concentration

As always, if you have any questions about the above, please feel free to call Chemical.net at 888- 243-6425
