Tandem Compressor and suction throttle valve applications: In part load, gas velocity should be
taken into account when selecting and commissioning pipework to ensure full oil return.
REMEMBER excessive pressure loss in interconnecting pipework will impair system performance;
this should be factored in during the design of the system and where necessary oil separators
employed.
