range with 3 compressors.
The new SM112-124-147 and SZ147 compressors
benet from a further improved design to
achieve the highest eciency.
Gas circulation, motor cooling and oil behaviour
are improved by a new patented motor cap
design.
Part protection and assembly reduces internal
leaks and increases life durability.
Improved part isolation reduces greatly acoustic
levels.
Gas intake design induces higher resistance to
liquid slugging.
Heat shield that lowers the heat transfer between
discharge and suction gas and the acoustic level
Improved lower bearing centering
Patented motor centering spacer
Patented motor cap
New PTFE spring seal for even lower leaks
