  What are the main types of air-cooled chillers? Air cooled chillers  are divided into four main types according to their compressors, as follows: 1. Scroll air-cooled chillers. 2. Screw-type air cooled chiller. 3. Centrifugal air-cooled chiller. 4. Piston type air-cooled chiller. How to replace the air filter of the air-to-chiller? 1. Turn off the air cooled chiller. 2. Determine the exact location of the air filter. 3. Check its size with a new one. 4. Remove the access panel. 5. Remove the old air filter. 6. Insert the new air filter following the arrow guide. 7. Close the access panel and turn on the air-cooled chiller. Do air-cooled chillers need a cooling tower? No, it does not require a cooling tower. In air, a chiller dissipates heat into the surrounding air, so it is used in areas where heat is not an issue. What is the difference between an air-cooled chiller and a heat exchanger? Both are pretty much used to provide cooling, but are slightly different in design. Ai...

  It’s common acknowledged that chemical factory is quite easy cause explosion if all the electrical products don’t handle well. Today we are going to share one of the cooling project with explosion proof chiller system to help you understand How to design a best   explosion proof industrial chiller   for Chemical factories. Project Overview This project is an industrial cooling project of Chemical Co., Ltd. The content of the project includes: 1. Pure water system: The dosage is 15T/day, and it needs to be reduced from 25°C to 4°C within 8H; 2. Chilled water system: water flow rate is 100m3/h, inlet water temperature is 12°C, outlet water temperature is 4°C; 3. Cooling water system: the water flow rate is 370m3/h, and the temperature difference between inlet and outlet water is 5℃. The explosion-proof grade of all electrical equipment is required to reach ExdIIBT4. Equipment configuration instructions 1. The cold source of the pure water system uses a model 20STB-25AD4 a...

  Spot welding machine is a kind of mechanical equipment. It adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current changes from one When the electrode flows through the other electrode, the two contact resistance points form an instant thermal fusion, and the welding current flows from the other electrode to the electrode along the two workpieces to form a loop instantly, and will not damage the internal structure of the welded workpiece. Because the resistance welding machine is in the working process, the resistance head is prone to high temperature, which affects the accuracy of the processed product, so a chiller is needed to cool it next to ensure the accuracy of the processed product. The spot welding machine is equipped with a chiller, which can improve the safety and stabili...

  Air-cooled chillers   are the most widely used chillers. They are widely used in plastics, electronics, chemicals, metallurgy, video pharmacy, electroplating, leather, crafts and scientific research in industry; they are widely used in hotels in business., Hotels, supermarkets and theaters. Air-cooled chillers are also the easiest chillers to install. Since the entire system of air-cooled water chillers is equipped with fans for heat dissipation, chilled water pumps, and chilled water tanks, customers only need to connect the chilled water inlet and outlet to their own equipment to be chilled to start use. The following is the air-cooled chiller structure:   When some customers buy chillers, they worry that they do not know how to install them after they buy them. In addition, the chiller suppliers are far away and it is not inconvenient to install them on site. In fact, these problems are very simple.  Oumal chiller  specializes in producing chillers for many...

  It is inevitable that the chiller will produce sound when it is working. For example, when the fan rotates, the fan blades rub against the air, it will produce sound. Normal sound is allowed. However, even the sophisticated refrigeration equipment will appear after a long period of use. Fault. Then, the editor of   Oumal Chiller   will take you to understand the causes and solutions of the noise produced by the chiller. First, find the reason from the parts that are easy to check and observe: 1. Are the anchor screws loose? The chiller is fixed on the ground. After running for a long time, the anchor bolts will be loose, and the chiller will be unstable, which will cause noise. This situation can be solved by replacing the anchor bolts, and vibration reduction can also be installed if conditions permit. The purpose is to make the chiller firmly fixed on the ground. 2. Whether the connecting pipeline is firm There are large and small pipes on the chiller, connecting the ...

  From the perspective of design to talk about the special "intelligent" creation of H.Stars Group,which is related to compressor type selection. According to the conventional thinking, the choice of compressor type is not much difficult , small unit with scroll compressor, medium unit with screw compressor, large unit with centrifugal compressor. Why mention the compressor type choice again? Let's do a simulation selection. Suppose we need a  300KW water-cooled chiller Screw Type，40STD-280WS4，Cooling Capacity:284kW，Price is 15200USD Scroll Type，20STB-100WFO4，Cooling Capacity:300kW，Price is 13500USD From the data, the cooling capacity of the scroll type chiller is 6% larger than the  screw type chiller , and the price of the scroll type chiller is 13% lower than the screw type chiller. We believe you have a clear idea of which product is more competitive. It is also applied to  Air cooled chiller .The following introduces the scroll type chiller and screw type chille...
