Features & Advantages
Double flexible design
Make sure the seal between the scroll discs.
Allowing the scrolls to be radially and axially separated,
debris or liquid may pass through the scrolls without damaging the compressor.
*Higher usage time and reliability.
*Better liquid tolerance.
*Better impurity tolerance.
High energy efficiency ratio
The scroll disc is running in rather than worn
*Increased performance with running time.
*High volumetric efficiency
Lower noise & vibration levels
Smooth sound spectrum & soft sound quality
*Compression chamber is always symmetrical
*Very low unbalanced stress
*High-precision manufacturing process
*No vibration absorption device
High strength metal composite bearing
*Space-age materials
*Porous bronze.
*PTFE coating
*Extend the running time without full lubrication
*Very small coefficient of friction
Unloading startup technology
The compressed parts are separated from each other after the shutdown to balance the internal pressure of the compressor,without the need for additional starting device.
