OPT CU coolant This option is available for all cooling units in the CU series.
filter
The coolant filter is equipped with a CrNi screen; its function is to filter dirt particles
above 100 micrometres in size from the coolant. This ensures that no coarse dirt
particles can pass into the coolant circuit. The coolant filter is fitted to the coolant return
connection on the cooling unit.
The option is included as standard on the CU 1100i /MV RVP cooling unit.
OPT/i CU level This option is available with the following devices:

The option is included as standard on the CU 1400i Pro/MC cooling unit.
The level sensor monitors the level of coolant in the cooling unit.
If both the OPT/i CU flow temperature sensor and the OPT/i CU level sensor options
are installed in the cooling unit, the level sensor works as follows:
-
If just the OPT/i CU level sensor option is installed in the cooling unit, the level sensor
works as follows:

• the cooling unit remains operational
If the coolant drops below the minimum level:
• the power source outputs an error message
• the level sensor interrupts the welding current
• the cooling unit is switched off
