Air-Cooled Screw Chiller Products Information


Features:
1. The compressor adopts the international brand. The original imported international brand BITZER Germany (Bitzer) HANBELL China Taiwan (Hanbell), a new type of high-efficiency screw rotor compressor, the efficiency is 20%-30% higher than the general compressor.
2. High efficiency 5:6 patented asymmetric rotor tooth profile.
3. Capacity control can adopt four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and stepless control system.
4. The combined design of 11 bearings and a-type axial thrust balance drum greatly increases the bearing life by 2.5-3.5 times.
5. The use of high-efficiency silicon steel sheet special groove design, and equipped with internal and external omnidirectional design cooling channel, so that the compressor motor can play the highest efficiency under any load.
6. The unique built-in oil pressure system does not need an oil pump to ensure that the compressor maintains the best lubrication effect. The oil separator adopts a double-layer filter method, which has a good oil filtering effect and the heat exchanger can exert its maximum capacity.
7. High efficiency, low noise and low vibration.
8. A variety of refrigerants are available. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c can also be used.

air cooled screw chiller working principle


Application range of air-cooled screw chiller:


Plastic industry: accurately control the mold temperature of various plastics processing, shorten the plastic molding cycle, and ensure the stability of product quality.

Electronics industry: Stabilize the molecular structure of electronic components on the production line, improve the qualification rate of electronic components,

Electroplating industry: control the electroplating temperature, increase the density and smoothness of the plated parts, shorten the electroplating cycle, and improve the production efficiency

Construction industry: supply chilled water for concrete to make the molecular structure of concrete suitable for the requirements of construction purposes, effective Enhance the hardness and toughness of concrete.

Vacuum coating: control the temperature of the vacuum coating machine to ensure the high quality of the coated parts.

Food industry: used for high-speed cooling after food processing to adapt to packaging requirements. There is also controlled fermentation, The temperature of the food, etc.

Chemical fiber industry: freeze-dry air to ensure product quality.

Dairy products, beverages; the production process often requires rapid cooling after heating, The steel pipe, water tank, and water pump of the chiller are required to be made of stainless steel to meet sanitary requirements.

Medicines, biological products; low temperature and low humidity environment is required during production and storage.

The line needs to be heated to reach a certain temperature before starting, and it needs to be cooled by chilled water due to its own heat generation after starting

To keep the temperature low.

Tempered glass; the general glass is heated at high temperature and then quickly cooled, the cooling water temperature should not be too high, otherwise

Will affect the quality of tempering. The industrial chiller is used to provide frozen water for cooling, and the water temperature does not love the influence of the ambient temperature.

Ensure the quality of the product.

Aquaculture; hotels, seafood restaurants, seafood farms, aquariums, providing frozen water in summer and heat in winter.
