Maintenance carried out prior to unit or system failure.
All cooling systems will require periodic maintenance to assure that proper freeze/boil protection is in effect and that adequate inhibitiors are present to provide corrosino protection. Thus routine or preventative maintenance will include a freeze point check using refractometer with freeze point adjustment if required. A check of coolant inhibition will also be included using the appropriate coolant test methods - typically but not always involving test strip.
