Danfoss DSH Series Application Guidelines

GENERAL INFORMATIONPRODUCT INFORMATIONINTEGRATION INTO SYSTEMORDERING INFORMATION SYSTEM DESIGN
Tandem and trio
requirements
Design piping
DSH 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, DSH 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.
For DSH240/295/381/485 you will need in
addition one mounting kit per compressor.

60Hz)
Suction and oil equalization piping
drawings must be respected (diameters,
minimum straight lengths, …)
