 It’s common acknowledged that chemical factory is quite easy cause explosion if all the electrical products don’t handle well. Today we are going to share one of the cooling project with explosion proof chiller system to help you understand How to design a best explosion proof industrial chiller for Chemical factories.

chilled water system

Project Overview
This project is an industrial cooling project of Chemical Co., Ltd. The content of the project includes:
1. Pure water system: The dosage is 15T/day, and it needs to be reduced from 25°C to 4°C within 8H;
2. Chilled water system: water flow rate is 100m3/h, inlet water temperature is 12°C, outlet water temperature is 4°C;
3. Cooling water system: the water flow rate is 370m3/h, and the temperature difference between inlet and outlet water is 5℃.
The explosion-proof grade of all electrical equipment is required to reach ExdIIBT4.

Equipment configuration instructions
1. The cold source of the pure water system uses a model 20STB-25AD4 air cooled low temperature industrial chiller, and the special manufacturing material in contact with the pure water is made of 304 stainless steel;
2. The chilled water system uses a 40STD-P800WSB4 single-head evaporative cold falling film type large temperature delta chiller with a water inlet temperature of 12°C and a water outlet temperature of 4°C;
3. The cooling equipment uses two HD-200 circular countercurrent cooling towers.

Project Advantages
1. The pure water system uses an air cooled low temperature industrial chiller. The entire unit is completed in the factory. Only the customer's water pipe needs to be connected on site, which is simple and convenient to install.
2. The contact part of the evaporator of the air cooled low temperature industrial chiller unit with pure water is made of 304 stainless steel, without the use of plate heat exchangers, saving the initial investment of the project;
3. The chilled water system uses an evaporative cold spray type large temperature difference chiller. The energy efficiency is the same as that of the flooded type type. The refrigerant charge is reduced by 50%, and the temperature difference between the inlet and outlet water is as high as 8℃. , Improve refrigeration efficiency;
4. The unit increases the heat recovery function, recovering waste heat to provide customers with free hot water for the front stage of steam heating, saving customers operating costs;
5. The unit adopts evaporative condenser for condensing, which has large air volume, good heat dissipation effect, and saves water than cooling tower;
6. The external circulating water pump of the chilled water system adopts frequency conversion control, and uses constant pressure water supply according to the customer's end load, which saves the customer's operating costs.

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 ...
