  The development of Chinese ink industry can be traced back to the beginning of the 20th century. Since the reform and opening up, the domestic ink market has developed rapidly, and inks have been widely used in various media such as paper, metal, glass, and plastic. In recent years, affected by the further advancement of environmental protection work, the price of some chemical raw materials has risen, and the growth rate of Chinese ink industry has gradually slowed down. In the past three years, the growth rate has been about 3.5%. The profit margin has also shown a downward trend. Oversupply has appeared in some regions. Ink sales have become fiercely competitive. In order to meet the needs of market competition, energy saving and consumption reduction and product quality improvement will be a major rule for ink manufacturers to enhance their corporate competitiveness. However, the research process is a key process in the ink production process, which has a key impact on both y...

  Low-temperature brine chiller   is also one of the more commonly used refrigeration equipment. Its refrigerant is the so-called brine solution, which has a low freezing point. It is especially suitable for medium and low temperature chillers to carry cold capacity. The temperature is generally required to be controlled below 0 ℃, which is usually used for the low temperature demand of some special production lines in industry. So, what kind of harm will be caused to the Brine chiller if the ratio of Brine refrigerant is not correct? The refrigerant is used to transfer the cold and heat generated by the refrigerator to the intermediate substance of the object to be cooled or heated. The common refrigerants are air, water, brine, organic compounds and their aqueous solutions; When the outlet water temperature is 0 ℃, the commonly used water-borne refrigerant will freeze. At this time, it is necessary to select appropriate refrigerant, such as brine, glycol, etc. the selection ...

  Nowadays, as the increasing economy of peoples life, more and more people are in need of ice rink . Therefore, many engineer company is worried about designing a best ice rink refrigeration system with reliability and energy efficient goal. Here are some best suggestions for you before you build an ice rink. Better take a look and it will help you save your time and money. 1.   Refrigeration system features The refrigeration system of indoor ice skating rink usually adopts two refrigeration methods: 1)   Direct expansion and indirect cooling. Direct expansion adopts condensing unit; 2)   Indirect cooling adopts\ screw type low-temperature chiller , Glycol is used as a refrigerant to form ice on the rink. At present, uses indirect cooling methods is more popular in the ice rink market. The cooling host should select more than two, one of which can meet the cooling under normal load conditions. When the conditions are relatively bad or the operating host needs to be ...

  How to measure brine concentration for the brine chiller ? Saltwater brine chillers  are also one of the more commonly used refrigeration equipment. Its refrigerant is the so-called brine solution, which has a low freezing point. It is especially suitable for medium and low temperature chillers to carry cold capacity. The temperature is generally required to be controlled at 0 Below ℃, it is usually used for the low-temperature requirements of some special production lines in the industry. So, what kind of harm will the improper proportion of brine-carrying refrigerant cause to the chiller and how to measure brine concentration for the brine chiller ? The refrigerant is an intermediate substance used to transfer the cold heat generated by the refrigerator to the object to be cooled or heated. Commonly used refrigerants include air, water, saltwater, organic compounds, and their aqueous solutions; when the outlet water temperature is 0°C, the commonly used water-borne refrige...

  H.Stars Group   has recently signed a contract with 90℃ dual source heat pump unit project for one of the famous automobile factory to replace the traditional boiler.

  Nowadays, chemical plants always consider how to reduce the initial investment and operation cost when they need to install a  low-temperature chiller system for the factory. Because low temperature refrigeration unit is a very important equipment in chemical plant, which plays an important role in safety production. The initial investment of   low-temperature refrigeration unit   is large, and it is also one of the equipment with large energy consumption in chemical plant. How to reduce the investment and operation cost of   Glycol low temperature chiller   and system is very important for enterprises. This is one of H.Stars Group projects for one of the chemical base . The cryogenic unit and chilled water circulation system are designed and implemented .At first, the company's design engineers only chose the Ultra low temperature chiller and system design according to the cooling capacity required by customers. However, with the deepening of the project...

  Recently, when communicating with some customers, we found that we were not very clear about the type selection and system design of low temperature units. However, the   low temperature chiller   is a very important equipment for chemical industry, raw material pharmaceutical factory and other enterprises, and it is also the place with the largest energy consumption for such enterprises. Therefore, how to select the appropriate number of industrial low temperature chiller and design a reasonable frozen water circulation system is particularly important. There is an example on  H.Stars Group  project reference.To us, the key points of  glycol chiller  design ,take the recent project of Anhui Xiangbang Chemical Co., Ltd. as an example, the total cooling capacity demand of the enterprise is 1500kW, and the outlet water temperature is required to be - 15 ℃. According to the experience, the following three points are sorted out for your reference: 1、 Sel...
