Semi-hermetic screw compressor water-cooled freezing condensing unit

Semi-hermetic screw compressor water-cooled freezing condensing unit
Product Detailed
1.Semi-hermetic screw compressor 2.High efficiency and energy saving 3.Low failure rate

Nanjing JLHB Environmental Technology Development Co., Ltd is specialized in refrigeration equipment production in east China and Jiangsu province. After years of stable management, it now has a great reputation among customers. It has one business hall(located in No.34, Huju South Road, Nanjing, covering about 500 square meters) and two factories(one is located in Yongyang Industrial Park, Lishui, Nanjing with an area of 20000 square meters, mainly manufacturing heat exchangers; another is in No.36, Runqi Road, Jiangning, Nanjing with an area of 4000 square meters, mainly producing refrigeration units). It also has branch companies in Shanghai, Guangzhou, Shenyang, Hefei, Wuhan, Changzhou etc. Our two main products are all authorized the ISO9001:2000 Quality Management System Certificate and we established an Automatic Unit Inspection Station (a national-level experimental center) with Hefei General Machinery Research Institute. 

Features of unit

1.application of economizer

 Increase the supercooling degree of liquid refrigerant and improve unit refrigerating capacity

2.reliable functional components

 For the water-cooled condensing unit, it uses newly high efficiency heat exchange tube to make dry expansion evaporator and condenser with high heat transfer efficiency, so it can improve refrigerating capacity of the unit and reduce input power;

 Solenoid valves, oil separators, electric components etc are all world famous brand with high quality and long service life.

3.application of environmental friendly refrigerant

Various refrigerant can be used, like HFC404A, HFC134a and so on

4.application of high efficiency oil separator

Reduce lubricant which flow in evaporator, so it can improve the heat transfer efficiency of evaporator

5.application of injection technology

 For screw compressor medium and low temperature condensing unit, injecting liquid refrigerant to the compression chamber of a compressor can reduce discharge temperature efficiently.

Features of semi-hermetic screw compressor

1. world famous brand screw refrigeration compressor;

2. Newly asymmetrical rotor profile · Best tooth ratio 5:6, furnished with high efficiency and low noise benefits;

3. Semi-hermetic design, only has three components, has the feature of less components, low failure rate, easy maintenance;

4. using world famous SKF and FAG thrust bearing and radial bearing, precise structure, high Reliability;

5. using double-layered and three-dimensional oil separators with high filtration efficiency, to make sure the normal operation of compressor and high efficiency heat exchange of heat exchanger;

6. fluoride-resistant, low iron loss motor design, with reliable motor overheating protection system to ensure reliable and high efficiency operation of motor;

7. equipped with liquid refrigerant injection system in medium and low temperature working condition, which can reduce work load of main components and discharge temperature, improve work reliability of compressor;
