  In 2004, the Ministry of Construction issued a document that chilled water must be used in the concrete mixer projects such as subways, bridges, and dams. The chilled water varies according to the outdoor temperature across the country, and the general temperature is 2℃-7℃ . H.Stars Group  has not been involved in this market before, and customers know little about chillers, so ordinary customers buy ice cubes and ordinary tap water to solve the problem according to production needs. According to relevant statistics, this market is worth more than 3 million dollars per year. At present, only a few  concrete chiller plant  pays attention to this market. Since the chilled water temperature in this market is 2℃-7℃, the chillers are generally ammonia machines. Competing with other chiller manufacturers in this market, H.Stars Group concrete water chiller can directly supply 2°C water with advantages in terms of technology, equipment, solutions, and services. As long as...

  Introduction: Winter is coming, and the ambient temperature is about to drop below zero. This will cause great damage to the chillers, water pumps, cooling towers, terminals and other equipment. In order to ensure that chillers work normally during winter, the chiller has to survive in the low temperature environment, because it will cause a great loss to users if the unit is not maintained with proper seasonal shutdown. First of all, when those chillers are not going to turn on during winter for seasonal shutdown, water among chillers, pipes, pumps, cooling towers and terminals must be drained out clean in advance when the ambient temperature is below zero. How are we going to do for the water chiller HVAC system shutdown in winter ? Here are the tips below for seasonal water chiller system shutdown in winter how to drain out the water from HVAC system. 1.  Shell and Tube Condenser : Open the end cap of the water pipe.  After opening, pay attention to the end cover and...

  From the perspective of design to talk about the special "intelligent" creation of H.Stars Group,which is related to compressor type selection. According to the conventional thinking, the choice of compressor type is not much difficult , small unit with scroll compressor, medium unit with screw compressor, large unit with centrifugal compressor. Why mention the compressor type choice again? Let's do a simulation selection. Suppose we need a  300KW water-cooled chiller Screw Type，40STD-280WS4，Cooling Capacity:284kW，Price is 15200USD Scroll Type，20STB-100WFO4，Cooling Capacity:300kW，Price is 13500USD From the data, the cooling capacity of the scroll type chiller is 6% larger than the  screw type chiller , and the price of the scroll type chiller is 13% lower than the screw type chiller. We believe you have a clear idea of which product is more competitive. It is also applied to  Air cooled chiller .The following introduces the scroll type chiller and screw type chille...
