Fronius - Cooling unit OPT/s CU 1200 /CK
- Available for power classes 320, 400 and 500
- New - as an option for the welding machine - no longer a separate unit
- Temperature monitoring by means of built-in temperature sensor ex works
- Combination of AUTO & ECO mode: energy-efficient by only starting cooling when necessary
- Fronius Cooling Liquid FCL10 and FCL20 can be used
- Can also be retrofitted (only with high welding unit housing G/W)
- MC (MultiControl) variant with flow sensor & connections for Duo setup
General information
- OPT/s CU 1200 (MC) is included as an option with the welding machine
- Supplied with FCL10 as standard
- FCL20 can be used as an option
- Temperature sensor as standard for both CU1200 variants
- 4,100,400,IK/CK CU 1200 has start-up monitoring included as standard
- When the pump is started, this monitors whether it is running into empty space or onto a resistor
- No monitoring during operation
- Flow sensor & Duo connections can be retrofitted via CKs
- 4,100,444,IK/CK CU 1200 MC has a flow sensor & the Duo water connections installed as standard
- Start-up monitoring is not active here as the flow sensor is installed
- Display of "l/min" possible
