Product Description

4FES-3Y 3HP Design Condensing Unit Project

Condensing units are widely used in cold room

This series of condensing units mainly produces semi enclosed Bitzer compressors, copper tube aluminum sheet air-cooled condensers, and shell and tube condensers; The air-cooled unit adopts an external rotor fan, which has low noise and high efficiency.

It has the following functions:

1. Adopting a semi sealed piston compressor, with reliable quality;

2. Open condensing unit, easy to install and maintain;

3. Cooling method: air cooling;

4. Copper tube aluminum finned heat exchanger;

5. Refrigerant R404A and R22 are both available

Customized Services

Technical requirements:

1. The fins are made of aluminum foil with a hole spacing of 25mm, a row spacing of 21.65mm, and a sheet spacing of 2.0mm; When flanging holes, there should be no cracks around them,

There should be no burrs, fragments or other adverse phenomena, and the color of the aluminum foil should be consistent:

2. After the assembly of the fins is completed, there should be no flipping or dirt on the fins;

3. The fins and copper pipes shall be connected by expansion, which is required to be firm and free from looseness. 4. The winter fiber welding points shall be welded firmly and free from welding defects such as false soldering and missing soldering; 5. After the assembly of the components is completed, it is required to conduct an airtightness test at a pressure of 3.5 ± 0.2MPa, immerse in water for at least 

5 minutes, and ensure that there is no leakage:

6. Fan equipped with external rotor motor: 2 * 4D450 (blade diameter) 7. Inlet pipe @ 25, outlet pipe 916
