How Does H.Stars Group Produce A High Quality Water Cooled Chiller

 Since H.Stars Group has been established for more than 28 years so far, some of you might wonder how H.Stars produces a high quality water cooled chiller. Below is the detailed production process with strict quality control system and 100% testing before delivery.


1. Chiller Frame welding: clean the bracket and select the appropriate welding method according to the specifications of the welding materials and the technical requirements.

5.Layout of electrical components
According to the electrical schematic diagram, the layout of the electrical components and the wire slot is reasonably discharged on the electrical base plate, and the hole position of the corresponding component and the installation hole position of the wire slot are marked with a pencil and drilled. The layout requires that the components should not be hindered by space during operation, and there should be no possibility of touching the charged body.




6.Electric control box and compressor wiring: The controller imports the latest version of the program according to the factory operation standards before installation, and sets and adjusts the corresponding parameters according to the model parameter comparison table and customer requirements.

8. Equipment testing station
National standard testing station, the factory equipment must be tested, and only after passing the test can the goods be delivered to ensure reliable product quality.

9.Large equipment testing center
H.Stars is capable of testing 800RT ~ 3000RT equipment, mainly detect centrifuge chiller and large chiller unit.

10.Insulation wrapping
According to the requirements of order, the thermal insulation will be wrapped accordingly. The chiller pump and related waterway system parts will be wrapped with thermal insulation after the unit passed the quality testing.

11.Outside spray

The main components the chiller except compressor, must be evaporator and condenser. According to customer requirements, the heat exchangers will be painted with required colors; After the heat exchanger is rust removed and gets polished ,it will be painted twice on the surface to secure the painting quality.

12. Packing Type
H.Stars is available to provide different packages according to exporting packing standard ,such as fumigated wooden cases and plywood boxes or reinforced shrink-wrap covering with industrial grade.

Where are water-cooled chillers used? What is a chiller used for?

  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...

Ways and solutions of noise produced by chillers - www.oumalchiller.com

  It is inevitable that the chiller will produce sound when it is working. For example, when the fan rotates, the fan blades rub against the air, it will produce sound. Normal sound is allowed. However, even the sophisticated refrigeration equipment will appear after a long period of use. Fault. Then, the editor of   Oumal Chiller   will take you to understand the causes and solutions of the noise produced by the chiller. First, find the reason from the parts that are easy to check and observe: 1. Are the anchor screws loose? The chiller is fixed on the ground. After running for a long time, the anchor bolts will be loose, and the chiller will be unstable, which will cause noise. This situation can be solved by replacing the anchor bolts, and vibration reduction can also be installed if conditions permit. The purpose is to make the chiller firmly fixed on the ground. 2. Whether the connecting pipeline is firm There are large and small pipes on the chiller, connecting the ...

How is the Refrigeration Industry Leading the Green Development with R404A

  As global environmental concerns continue to rise, the refrigeration industry is undergoing a significant transformation. Water-cooled low-temperature units exported overseas are now increasingly adopting the eco-friendly refrigerant R404A, leading the way in the industry's green development. Here's a deeper look into this trend. Why Is R404A Becoming the Preferred Refrigerant for  Water-Cooled Low-Temperature Units ? R404A is a blend of refrigerants that stands out due to its environmentally friendly properties. It is free from Ozone Depleting Potential (ODP) and has a relatively low Global Warming Potential (GWP), making it an ideal substitute for traditional refrigerants. This balance between high-performance cooling and environmental friendliness has made R404A especially popular in regions with strict environmental regulations, such as Europe and North America. Water-cooled low-temperature units exported to these areas are now commonly equipped with R404A to meet local ...
