  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 years. And will provide

  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 chiller, cooli

  The application of chillers is very wide, including plastic industry, chemical industry, packaging industry, printing industry, food industry, etc. Today we will talk about how to choose chillers in the food industry. The   water chiller   used in the food industry needs to be used for rapid cooling of all kinds of food after heating, so that it can be suitable for canning and bottling requirements. In addition, various fermented foods require different cooling temperatures to stabilize fermentation needs and improve fermented products. To ensure the quality of fermentation, it is also used in the pharmaceutical, chemical industry, and refrigeration equipment. When choosing a chiller in the food industry, first consider the temperature of the chilled water required in the process, whether to use a medium-temperature chiller or a low-temperature chiller, and secondly, consider whether the cooling water needs to be in direct contact with the food? If it is to directly cool food, the pl

  The structure of low-temperature chillers is similar to that of piston chillers. Low-temperature chillers generally refer to chillers whose outlet temperature is less than or equal to 5°C. They are mainly used for process cooling in food processing, chemical, pharmaceutical and other industries. Low-temperature chillers are usually used for low-temperature requirements on certain special production lines in the industry. Low-temperature chillers can generally reach about -40°C. Low-temperature chillers  are quite different from conventional chillers in terms of unit design due to the lower temperature of the outlet water. The most basic difference is that on the chilled water side, the cryogenic unit needs to be added with the appropriate type and concentration of antifreeze. Low-temperature chillers include low-temperature air-cooled chillers, low-temperature water-cooled chillers, low-temperature screw chillers, and low-temperature piston chillers. So how to control the temperature

  Dairy industry production line has to adopt chiller for its dairy processing , however, it’s very important for the enterprise to select the right chiller ,especially the high efficiency with more energy saving after it’s installed.   Heat recovery water cooled screw chiller   has become more and more popular among those chillers. In order to avoid selection mistake , here is an good example for one of the diary factory for your reference. A Yogurt Co., Ltd. is a high-end yogurt dairy processing enterprise invested and established by one of the Biological Engineering Co., Ltd since 1999. It is a modern dairy enterprise integrating R&D, production, sales and cold chain logistics. Dairy production workshops have a large demand for cooling capacity, and chillers generally operate all year round, with extremely high utilization rates. This feature puts forward high requirements on the energy consumption, operation and maintenance, and stability of the equipment itself. Project Overvi

  Water cooled screw chiller   is a water to water chiller which compressor use semi-hermetic screw type. It’s high efficient water chiller system. The cooling water system including a water cooled screw chiller, a cooling tower, a water tank, and 3 water pumps. Water cooled screw chiller is widely used in the industrial cooling system. High pressure failure of the water cooled screw chiller is the common failure when it working. While how to deal with the high pressure failure of the water cooled screw chillers. Blow let’s talk with the Possible causes and solutions of the high pressure. 1. The temperature of the chiller is too high and the condensing effect is not good. The rated working temperature of the cooling water required by the water-cooled screw chiller is 30℃-35℃. The high water temperature and poor heat dissipation will inevitably lead to excessive condenser pressure. Occurs in the high temperature season, the reason for the high water temperature may be: cooling tower fai
