Hermetic scroll compressors

Hermetic scroll compressors are positive displacement compressors used in HVAC and refrigeration systems where high efficiency, low vibration, and stable operation are required.

The scroll compression process uses two interleaved spiral elements to compress refrigerant in a continuous motion. This provides:

Smooth, low-pulsation compression
Fewer moving parts
Stable part-load performance
Suitability for modulating refrigeration systems

For refrigeration applications, MLZ and LLZ are the primary scroll compressor ranges used in commercial cooling systems.

Features and benefits

Continuous compression with low vibration
High seasonal efficiency
Suitable for rack and distributed systems
Vapor injection capability on selected LLZ applications
Compact compressor footprint
Broad refrigerant compatibility
