How to reduce the initial investment and operation cost of low-temperature chiller for chemical plants

 Nowadays, chemical plants always consider how to reduce the initial investment and operation cost when they need to install a  low-temperature chiller system for the factory. Because low temperature refrigeration unit is a very important equipment in chemical plant, which plays an important role in safety production. The initial investment of low-temperature refrigeration unit is large, and it is also one of the equipment with large energy consumption in chemical plant. How to reduce the investment and operation cost of Glycol low temperature chiller and system is very important for enterprises.


low-temperature chiller unit


This is one of H.Stars Group projects for one of the chemical base . The cryogenic unit and chilled water circulation system are designed and implemented .At first, the company's design engineers only chose the Ultra low temperature chiller and system design according to the cooling capacity required by customers. However, with the deepening of the project, H.Stars Group has found that the project can reduce the amount of chiller assembly by recycling the cooling capacity, so as to reduce the initial investment and operating costs.

This is a low-temperature crystallization chemical project. The whole process is heating up first and then cooling down to obtain different chemical products. The next stage of process cooling is completed by low-temperature refrigeration unit, and then the crystalline finished solution is separated by centrifuge. The separated low-temperature solution is cooled again in the previous process (called tank B) to obtain another product. However, because the volume of tank B is limited, it is necessary to supplement low-temperature water to obtain the desired product in tank B.

In this process, H.Stars Group has designed an external heat exchanger to be added to fully exchange the heat between the high-temperature mixture entering the tank B and the low-temperature solution, fully absorb the cold capacity of the low-temperature solution, and then enter the tank B to crystallize to form the product, thus greatly reducing the cost of low-temperature preparation cooling capacity of chiller unit.


Through such a change, the low-temperature chiller unit needed 1800kW before, but now it only needs 1300kW, and the investment cost and operation cost have been reduced by about 25%, which has brought great value to the enterprise. At the same time, H.Stars Group also realize that it is particularly important to fully understand the production process of customers for the selection of refrigeration equipment, which not only reduces the initial investment cost, but also greatly reduces the operation cost, bringing great value to customers.

H.Stars Group has rich experience in the design and selection of low temperature chiller unit, and 28 years of professional experience has won constant praise in the field of cryogenic chemical industry.

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 ...
