High Reliability:

• Duty Cycling: Duty cycling equalizes the running time of the outdoor units in a multiple-unit system and of the compressors in each unit, significantly extending compressor lifespan.(Super VX series).

Precise Oil Control Technology:
Four stages of oil control technology ensure all outdoor compressor oil is always kept at a safe level, eliminating any compressor oil shortage problems.

• Compressor internal oil separation.
• Oil balance pipes between compressors ensure even oil distribution to keep compressors running normally
• Auto oil return program monitors the running time and system status to ensure reliable oil return.
