Fronius CU 800i - General technical information; CU 800 i and CU 800 i;460 V specifications

Technical data
General The cooling capacity of a cooling unit depends on
- Ambient temperature
- Delivery head
- Flow rate Q (l/min) - The flow rate Q depends on the length of the interconnecting
hosepack and the diameter of the hose.
