Specifications

1. Features: 

 

1) Introdution

Developed technology, compact dimensions

Small volume and space

High precision machining to ensure the compressor confirm with the standard

CNC processing center

Concentricity due to specific processing technology

Minimal dead space

Steady operation, small vibration and low noise

Excellent stability

Refrigerant like R22 and R404 are adopted to protect the environment

For mid&low temperature application

Electrical motor protect device

PTC sensor

Wear resistant driver gear

Chrome plated piston rings and aluminum pistons

Hardened crank-shaft

Low friction bearing set

Efficient valve plate design, high refrigerating capacity and low energy consumption

Efficient compression rate

Valve reed made of imported impact resistant spring steel

General spare parts, convenient for maintenance

 

2)Wide range of application

   The Compressor uses R22 as refrigerant. R134a, R404a, R407b and R407c are also approved. R12 and R502 are not suggested due to the international environment protection requirement. The machine can be used at a low or high condensing temperature.

 

3)Excellent performance

   The compressor has a scientific structure design, strictly chosen material and precise procession and it is strictly inspected. The factory has obtained the National Compulsory Products CCC Certification, the National Industrial Products Manufacture License, and the ISO9001:2008 International Quality Supervision System Certification. 

 

4)Reliable safety device

  The compressor is equipped with motor protector and discharge temperature monitor to prevent the overheat of the motor and the compressor and the operation beyond approved application pressure.

 

2.Accessories of YEMOO Condensing unit:

 

Note: Our connecting welding rod is using Harris imported from USA. Other spare parts can based on the customer's requests.
