Tandem and Trio requirements (Static)
DSF tandem and trio use static oil balancing principle to equalize oil level between the compressors by gravity. This
is ensured by a precise suction and oil equalization piping design.
The discharge line has no impact on oil balancing. It is shown with tee, to indicate that both left and right side
discharge headers are possible.
By default, DSF tandems and trios are not factory-built.
To complete an assembly in the field, you will need:
• Tubings, according to specific outline drawings indicated in the following table
• Manifolding accessory kit
• Compressors
