Daming— Frozen scroll compression technology provides superior solutions for freezing applications.

Scroll compressor is the ideal choice for high reliability, high energy efficiency and compact system design.

DM series can provide products of 3hp-15hp, and its applicable refrigerants include R22, R404A, R134A, etc.

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.
