Industrial Chiller

The heat pump is based on the reverse Carnot cycle principle. It doesn’t cost many electricity by refrigerant system. Using refrigerant as carrier to continuously absorb the free low-grade heat energy in the heat source and convert it into high-grade heat energy, thus realizing the transfer of low-temperature heat energy to high-temperature heat energy. According to the different heat source ,H.Stars Group heat pump can be divided into  sewage source heat pump ,  air source heat pump , water source heat pump and  ground source heat pump . Hotel and SPA center will use a lot of hot water every day. Suitable hot water equipment can save a lot of energy cost. H.Stars  Sewage source heat pump and air source heat pump are favored by many users because of their energy saving, environmental protection, high efficiency and many other advantages. So for the hotel and bath industry to choose which heat pump equipment is more suitable? We will give you a comparison...

How to manufacture the shell and tube heat exchanger  I Shell and tube heat exchanger is a kind of heat transfer device, which is composed of shell, tube plate, tube bundle, baffle and cover; How is the manufacture to produce the  shell and tube heat exchanger ? In the manufacturing of heat exchanger, the manufacturing process of cylinder, head and other parts is the same as that of general container manufacturing progress, but the requirements are different. The inspection of materials, drilling of tube plate and baffle hole, welding of cylinder and processing of flange are the key points to the quality. Throughout its manufacturing process, most of manufacturer still use traditional processes, in which the proportion of welding is relatively high, so it is necessary to weld in strict accordance with the welding process, and to detect the weld. The heat exchanger produced by H.Stars Group subsidiary company UAR, has gone through 18 processes. It has been meticulously...

Introduction of explosion-proof chiller: International Industries have demanded a lot from their HVAC machines. Some of equipment might be susceptible to explosions inside and outside their circuitry. Getting an  explosion-proof chiller  is essential for many industrial environments. However ,very few factory can manufacture explosion-proof chillers with mature technology and skilled engineers. H.Stars Group is one of the very few companies that can build explosion-proof machines. H.Stars team of engineers from R&D to quality inspection ensures that all explosion-proof chillers will definitely meet the standards of reliable equipment. H.Stars technicians and specialists have possessed 27 years of experience in designing machines. It is mainly used in special places such as inflammable and explosive, and the production power ranges from 10HP-200HP. Can be customized according to customer requirements. The components of the chi...

As the development of industry, Thailand become a country with powerful demand on technology, especially focus on energy saving and environmentally friendly products. Under this background,  UAR Heat Exchanger , self-made by H.stars Group was marketed as a major product in this exhibition. Falling Film Heat Exchanger is one of our main marketing products, which COP reach 6.1, widely be used on Flooded type chiller, can save 30% refrigerant cost, attracting the attention of many Thai engineering companies to discuss for t he future cooperation. In Thailand, there are numerous of engineering company assembling chillers by themselves, end users are also more willing to buy brands with local after-sales service. As a result, ordinary chiller market is highly competitive. At the fair, we meet several customers with whom we talked through Internet before and have a deeper understanding of each other after meeting. They also provided us valuable informa...

During October 9th to 11th, 2019, H.Stars group has successfully participated in the 2019 efrigeration & HVAC Indonesia at JIExpo Kemayoran, Jakarta, Indonesia. The exhibition area is around 4,500 square meters, with 130 exhibitors with around 5500 visitors. Indonesia is not only the ASEAN large refrigeration and air-conditioning market, It will also become the ASEAN's transit base with growing demand at a rate of 15%-20% annually.  The main products presented by the H.Stars Group in this Indonesia exhibition included  magnetic oil free centrifugal chillers , large capacity of   flooded type screw chillers   and  UAR shell and tube heat exchanger s . This Indonesian exhibitors are all from the world's leading companies in the HVAC industry, not only have internationally renowned companies exhibiting, exhibits are mainly compressors, industrial chillers. At the same time, we have also visited several lo...

The 5000RT cold room generally equipped with various refrigeration equipment, which can be controlled and maintained stable low temperature facilities. Its basic components are:  refrigeration system, warehouse with certain thermal insulation performance, attribute buildings, etc. H.Stars Group   has been committed to providing customers with complete low temperature condensing chiller unit scheme since 1992. The 5000RT cold room is mainly used for food freezing processing and refrigeration. It keeps a certain low temperature indoors through artificial refrigeration. The walls, floors and flat roofs of 5000RT cold room are covered with insulation materials of certain thickness to reduce external heat transfer. In order to reduce the absorption of solar radiation energy, the surface of the external wall of 5000RT cold room is usually painted white or light color, so 5000RT cold room building is different from the general indust...

1. Some special production processes such as: testing, precision material testing, precision instrument cooling water system, etc., need to ensure that the circulating cooling water inlet water constant temperature or high precision, so that the data or product performance is stable. 2. Water for food and medicine must ensure the temperature of the mixing water to ensure the stability of the product and the quality of the products in the four seasons. 3. During the product development phase, product performance, thermal testing or cold testing is required. Some products require watering, spraying, circulating water cooling systems, etc., and also require different temperature data such as high temperature and low temperature. H.Stars  high-precision chiller  is specially designed for the current high-power industrial chiller with low temperature control accuracy, low safety, poor water quality, and can not meet the matching needs of precision equipm...
