Reference values from the Chaoyang Guangda LM catalogue — typical figures rather than guaranteed limits. Confirm the exact model and concentration on the current model TDS before specifying.
View source: catalogue p.29 (PDF p.33)The catalogue classifies LMH as a hazardous chemical. Dosage and replenishment require a technical programme; do not treat reference figures as universal instructions.
Calcium chloride brine is efficient and severely corrosive. Compare it with modern secondary coolants at the same freezing point, and see how inhibitor programmes work.
Measured weight-loss data from the Institute of Metals shows how these fluids perform against glycol. See what it covers and how to specify with it.
