IV. Installation: Line Sizing, Piping
Line Sizing
Contact Haskris for help: Haskris is available to review pipe runs, pressure drop, etc. and make
recommendations for individual sites.
Approach to line sizing
• Size all interconnecting hose and piping equal to or larger than the connections on the chiller.
• Pressure drop in the external piping is a function of fluid flow rate, pipe inner diameter, pipe
length, the number and type of fittings, and other factors.
• Generally, external piping should be sized to minimize pressure drop. Approximately 5 psi to
10 psi (0.34 bar to 0.7 bar) or less is a good goal
For applications requiring approximately 50 LPM (13.2 GPM) or less
• If the total straight pipe length is less than 1,100 ft (335 m) use 1-1/2” nominal pipe size (ID).
For applications requiring approximately 100 LPM (23.8 GPM) or less
• If the total straight pipe length is less than 300 ft (91.4 m) use 1-1/2” nominal pipe size (ID).
• If the total straight pipe length is less than 1,200 ft (366 m) use 2” nominal pipe size (ID).
For applications requiring approximately 150 LPM (31.7 GPM) or less
• If the total straight pipe length is less than 120 ft (36.6 m) use 1-1/2” nominal pipe size (ID).
• If the total straight pipe length is less than 500 ft (152 m) use 2” nominal pipe size (ID).
For applications requiring approximately 200 LPM (52.8 GPM) or less
• If the total straight pipe length is less than 50 ft (15.2 m) use 1-1/2” nominal pipe size (ID).
• If the total straight pipe length is less than 310 ft (94.5 m) use 2” nominal pipe size (ID).
• If the total straight pipe length is less than 925 ft (282 m) use 2-1/2” nominal pipe size (ID).
