copeland discuss ompressor semi-hermetic DWM series
L, C, 3S, 4S, 6S semi-hermetic refrigeration compressors are high-quality and high-performance products produced by advanced technology and equipment. Air-cooled condensers are produced by secondary flanging fins and mechanical tube expansion process. High-quality and high-efficiency copper tube aluminum fin heat exchanger. This unit has compact structure, excellent performance and reliable quality.
Technical parameters Wind The air-cooled units in the table below are equipped with large fan blades and low-speed axial flow fans, which have the characteristics of large air volume, low noise, and a small number of fans.
Each series of air-cooled compression condensing units is composed of a semi-hermetic refrigeration compressor, an air-cooled condenser, a liquid receiver, a drying filter, a pressure gauge, and a pressure controller. Semi-hermetic refrigeration compressors are high-quality, high-performance products produced by Emerson Environmental Optimization Technology (Shenyang) Refrigeration Co., Ltd. using advanced technology and equipment.
1. High volumetric efficiency: The pressure difference between the adjacent crescent spaces of the scroll compressor is small, the leakage is small, there is no steam suction and exhaust valve, the resistance is small, and there is no re-expansion of the clearance volume.
2. High adiabatic efficiency: Under the same cooling capacity, the scroll compressor is about 10% higher than the reciprocating type. 
3. Low noise and small vibration of the whole machine
4. The Copeland compressor has a solid cast iron body to provide a large heat dissipation area to improve the cooling effect of the compressor, and uses a lightweight aluminum piston to reduce friction and vibration. It has a cutting-edge electronic protective film block that can provide comprehensive motor protection.
