  1、   Introduction: With the implementation of the national strategy of developing the ocean, the use of petrochemical devices on my country's offshore platforms has developed rapidly.  Seawater heat exchanger  is an important equipment that is most widely used in offshore platform operations. The heat exchange status of the heat exchanger directly affects the smooth operation of the entire platform and the comprehensive economic indicators, and has a great impact on the safety, stability and long-term operation of production. It plays an important role. The selection of materials is a very important link in the design of seawater heat exchangers. Whether the selection of materials is appropriate has a great impact on the production, safety, maintenance and technical transformation of the device. For the selection of heat exchanger materials, the relevant standards and specifications should be strictly followed, and the best materials should be selected according to...

  Although most of the various   industrial chillers   produced in my country are imported compressors, which have a long service life, but in actual use, if the user does not carefully maintain and maintain the compressors of the industrial chillers, Different degrees of failures will also occur, seriously affecting the performance of the entire industrial chiller. There are several effective measures to prevent industrial chiller compressors from malfunctioning, including: Regular maintenance: Regular maintenance of the compressor, including cleaning and replacing parts, can prevent malfunctioning due to wear and tear.During the use of industrial chillers, it is necessary to pay attention to the noise of the compressor at all times. If the noise increases significantly, according to the experience introduced by the industrial cooler factory, it is necessary to complete the shutdown inspection in a timely and effective manner at this time to ensure normal operation. On t...

  As we all know , the society is urging all enterprises to fulfil their obligation on energy saving to keep the earth green for our next generations. H.Stars Group has developed a ner product of   magnetic VFD oil-free centrifugal chiller   to be able to provide  comprehensive partial efficiency IPLV of the unit upto 10, and the partial load energy efficiency value exceeds 13. The operating noise of the unit is only 76dB, and the frequency conversion starts, and the starting current is only 2A. Suitable for pharmaceutical factories, large commercial places, etc. Electricity cost comparison table with traditional chillers Unit cooling capacity range: 560KW-7800KW Chilled water outlet temperature range: 5-20℃. In addition to standard specifications, various types of non-standard units can also be customized according to user requirements. Structure of magnetic centrifugal chiller with VFD: Features of Water-cooled magnetic centrifugal chiller with VFD: 1) COP up to 6....

  The 21st century is a century of rapid technological development. The global population has exceeded 6 billion, and the shortage of land resources has increasingly become a common concern of all countries. The utilization of underground space will also be paid more attention. Country's tunnel construction has achieved leap-forward development in recent years. As of 2019, there are 56 cities in mainland China with a total line size of 6,902 kilometers. Among the 6,902 kilometers of construction lines, underground lines are 5,632 kilometers, accounting for 81.6%, and ground lines are 416 kilometers, accounting for 6%; elevated lines 853.2 Kilometers, proportion, 12.4%; The estimated demand for  water-cooled screw chiller  in this market is USD 5 million per year. At present, we have a model case and hope to achieve excellent performance in this sub-industry. H.Stars Group has invested capital in this industry since the last few years . Below is one of H.Stars Group projec...

  More dust and poor water quality in  the chiller environment will affect the normal operation of the equipment, and even lead to downtime. In order to increase the operating power of the chiller, it is necessary to create high-quality conditions for use and effectively maintain the operating power of the  air-cooled chiller . ​ When using the chiller, if there is a lot of dust and other problems in the environment during the operation of the equipment, the normal operation of the equipment will be affected after the equipment enters the water-cooled chiller. In order to prevent the chiller equipment from being affected by dust in the environment and a large amount of scale due to long-term lack of maintenance, companies need to conduct professional inspections on chillers on a regular basis. A layer of solid or ooze builds up, called fouling, which adds additional fouling thermal and flow resistance, increasing required heat transfer area, power consumption and maintena...

  Air-Cooled scroll chiller   VS   Air-Cooled Screw Chiller Functionally: The air-cooled screw chiller and the air-cooled scroll chiller have the same cooling function. The cooling, heating and energy are all electric energy. Application industry: are mainly used in industry, medicine, plastic, food, coal, shopping malls and other industries. It can be installed on the roof or outdoor courtyard, without the need for a dedicated machine room and cooling tower. The smallest air-cooled screw chillers are 30HP/30Ton, while air-cooled scroll chillers range from 1HP/1Ton to 60HP/60Ton. The two categories differ on the basis of capacity range. Another difference is that screw chillers do not have a built-in water tank and water pump, while air-cooled scroll chillers have a water tank and water pump. Furthermore, it has a compact design, so it is easy to integrate. Unlike screw chillers with touch screens, air-cooled scroll chillers are equipped with an easy-to-use PID controller...

  Water-cooled chiller   is a cooling water device that can provide constant temperature, constant current and constant pressure. A chiller is a machine that achieves refrigeration through vapor compression or absorption cycles. These liquids can flow through heat exchangers to cool the air or equipment. The industrial chiller can always output ice water with a lower temperature than the ambient temperature. It can be used wherever cooling is required, either direct cooling or indirect heat exchange. The main components of a water-cooled chiller are compressor, condenser, evaporator, water pump, and water tank. Chillers have a wide range of applications. The chiller can be used to cool the injection mold, improve the quality of plastic products, cool the vacuum coating, control the temperature of the vacuum coating machine, cool the food industry, fast cooling processing, chemical industry, effectively control the temperature of chemicals, cooling buildings, concrete fast Cool...
