1. What Is a Hermetic Scroll Unit?

A Hermetic Scroll Unit is a fully sealed refrigeration or HVAC compression system that integrates a scroll compressor within a hermetically welded shell. Unlike semi-hermetic or open-type compressors, the motor and compression mechanism are enclosed in a sealed housing, preventing refrigerant leakage and external contamination.

This design enhances reliability, improves energy efficiency, and reduces maintenance requirements — making it a preferred choice for commercial air conditioning, cold storage, supermarket refrigeration, and industrial process cooling.

2. How Does a Hermetic Scroll Compressor Work?

The scroll compressor inside the hermetic unit operates using two interleaved spiral-shaped scrolls:

• One scroll remains stationary
• The other scroll orbits around it
• Refrigerant gas becomes trapped and compressed toward the center

This continuous compression process eliminates the need for suction and discharge valves, reducing vibration and mechanical wear.

Working Process Overview

1. Low-pressure refrigerant enters the outer chamber
2. Gas becomes trapped between scroll wraps
3. Orbital motion gradually reduces volume
4. High-pressure refrigerant exits from the center port
