Waterside Pressure Drops
Constant water flow MUST be maintained. Variable water volume is NOT recommended and may
invalidate warranty.
CAUTION
Use the formula below to calculate the External Head Available:
Total Pump Head Available - Chiller Pressure Drop = External Head Available
Example (UCCL 125DX-4AKK 8.0 l/s, standard single pump):
190 kPa - 75 kPa = 115 kPa
For glycol solutions, please refer to Glycol Data.
Pressure drops shown are for the standard unit without optional pumps and/or pipework.
