Tandem requirements Danfoss scroll compressor H series tandem 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 designs.
The discharge line as no impact on oil balancing
and is shown with tees, to indicate that both left
and right side discharge header are possible
Danfoss scroll H series compressors in C8 version
can be mounted in tandem assemblies.
By default, H series tandems are not factory-built,
just provide tandem version compressors
(feature 8).
Such manifolding applications require special
design considerations that go beyond the scope
of this document. Please contact Danfoss for
further information.
For each tandem configuration, specific outline
drawings are available as indicated in following
tables.
