Estimate the total coolant volume for your cutting system
The capacity of the coolant reservoir for the XPR cutting system is 22.7 liters to 45 liters
(6 US gallons to 12 US gallons).
A cutting system with long leads requires more coolant than a cutting system with short leads.
To calculate the estimated total coolant volume necessary for your cutting system, use the
calculations below:
For total estimated volume in liters:
For total estimated volume in US gallons:
Refer to Coolant Installation on page 199.
Replace all of the coolant
The use of old coolant can decrease coolant flow, which can cause higher torch temperatures that
shorten the life of consumable parts.
Hypertherm recommends that you replace all of the coolant at least once every 6 months, as part of
routine preventive maintenance. More frequent replacement can be necessary because of
environmental conditions including but not limited to contaminants in your coolant or diagnostic
codes that indicate coolant problems.
For instructions about preventive maintenance (such as weekly, monthly,
and yearly tasks)
refer to the XPR Preventative Maintenance Program
(PMP) Instruction Manual (809490).
Adding new coolant to the reservoir when the coolant level is low is not the same as replacing all of
the coolant. All of the coolant must be removed in order to flush the coolant system.
The steps below describe how to remove all of the old coolant. Refill the cutting system with new
coolant only after you remove all of the old coolant.
For coolant installation steps, refer to Coolant Installation on page 199.
