  The normal and safe operation of the chiller is inseparable from the refrigerant. It is the working medium that circulates in the chiller refrigeration system to achieve refrigeration. The commonly used refrigerant types for chillers are: R22, R407C, R404A, R410A, R134A, R507... Because R22 refrigerant is not environmentally friendly, most countries have now banned the use of R22. Therefore, for Omar chillers, high temperature The chiller uses R407C refrigerant, and the   low-temperature chiller   uses R404A. Of course, R134a, R410A, etc. can also be used according to user requirements. So, how to choose the appropriate refrigerant type for the chiller? R22: Because R22 destroys the ozone layer, many countries have now banned the use of R22. Therefore, the chillers we export are generally R407C systems, unless customers require special requirements. R407C: R407C is a mixture of R32 refrigerant and R125/refrigerant plus R134a refrigerant in a certain proportion. It is an environmental

  There are many types of   industrial chillers . When purchasing a chiller, different chiller suppliers make different chiller solutions. Therefore, customers need to face choices in the process of purchasing chillers. How can they choose a suitable chiller Suppliers?  Are there any problems that we need to pay attention to when purchasing chillers? The following Oumal chiller manufacturer will take you to analyze together. First of all, when purchasing a chiller, it is necessary to know whether it is an air-cooled chiller or a water-cooled chiller, whether the chiller model recommended by the supplier meets your requirements, whether the cooling capacity is sufficient, and whether the power supply voltage matches , If different chiller suppliers have different prices, we compare air-cooled chillers with water-cooled chillers, it will be difficult to choose a suitable supplier. Because the price of water-cooled chillers is cheaper than that of air-cooled chillers. The same water-coole

 The  air-cooled chiller  is one of the chiller models. It cools the water at room temperature to a certain temperature through the compressor of the chiller to strengthen cooling of the mold or machine. It is used as a stand-alone machine. The heat sink is a built-in fan. There are three main mutual Linked systems: refrigerant circulation system, water circulation system, electrical automatic control system.   The air-cooled chiller is mainly used to cool the heating components of the equipment to ensure the normal operation of the equipment at a constant temperature. The air-cooled chiller is suitable for high-speed spindles, electric spindles, CNC machine tools, coordinate boring machines, grinders, machining centers, laser marking machines, laser engraving machines, laser welding machines, laser coding machines, laser cutting machines and other equipment. It is also widely used in the following industries. Injection rubber process: cast film, composite film, blown film, bottle blow

  Explosion-proof chillers   require all component with electricity to be explosion-proof and will be equipped with an explosion-proof certificate. Explosion-proof chillers are based on standard chillers and are specific explosion-proof measures taken to prevent electrical equipment from igniting the surrounding explosive gas environment. It is an integral explosion-proof system. In addition to the explosion-proof performance of all electrical components, it must also consider the overall explosion-proof performance of the unit to meet the standard requirements. It provides a comfortable and safe production environment for people in explosion-hazardous places (in addition to the performance of the product itself, the safety guarantee also depends on reasonable selection, correct use and maintenance).   Explosion-proof chillers are mainly used in chemical, ink printing, dusty environments, oil refining, petrochemical and other flammable and explosive industries that require protection.

  Ice sports cannot be separated from ice rinks. With the development of technology, artificial ice rinks are constantly emerging. The design of the artificial ice rink should consider the location conditions of the ice rink, the purpose of the ice rink, and the geographical location of the ice rink. The design of artificial ice rink should pay special attention to the requirements of ice rink structure design and load calculation. How to select the qualified chiller for an Ice skating rink?   HST AR S Group   will help you to select the best ice rink chiller , because gradually some Hockey players have complained about the conditions of the ice rinks which might arise from humidity, leakage, or wrong ice temperatures. The refrigeration technology underlying ice rinks is in fact the same as in refrigerators and air conditioners. 1. Load calculation of ice rink The main difference between ice rinks and refrigerators or air conditioners is that the refrigerant doesn’t cool the ice direct
