Coolant requirements for operation between -10°C – 40°C (14°F – 104°F)
Use the Hypertherm® premixed coolant for the usual operating temperature range for plasma cutting systems. Adjust the coolant mix to operate the system at temperatures that are colder than -10°C (14°F).
Use Hypertherm premixed coolant (028872) when operating in a temperature range of -10°C – 40°C (14°F – 104°F).
If you use shield water, the temperature range for cutting system operation and storage is reduced to 0°C – 40°C (32°F – 104°F).
If it is possible for the temperature to go below -10°C (14°F) when the cutting system is not in use, adjust coolant propylene glycol concentration to 50% to prevent damage to cooling system components.
Operating your plasma cutting system below -10°C (14°F) is not recommended due to reduced consumable life and performance.
To increase the coolant propylene glycol percentage, add 100% propylene glycol (028873) to the premixed Hypertherm coolant (028872) according to the following calculation. The maximum percentage of propylene glycol should never exceed 50%. Also refer to Make an estimate of the total coolant volume.
| Total system coolant volume (in liters) | X | 0.4 | = | Total volume in liters of 100% propylene glycol to add |
| Total system coolant volume (in U.S. gallons) | X | 0.4 | = | Total volume in U.S. gallons of 100% propylene glycol to add |
