Trio unit MLM/MLZ116
Operating principle
Composition of MLM/
MLZ116 trio
MLM/MLZ116 trios could only use active system
to balance the oil level between the compressors.
Each of the compressors may run alone to
provide proper capacity for part load operation.
The system has been designed to ensure a
precise pressure balancing between the sumps,
facilitating the oil equalization by gravity.
