 How to measure brine concentration for the brine chiller ?

Saltwater brine chillers are also one of the more commonly used refrigeration equipment. Its refrigerant is the so-called brine solution, which has a low freezing point. It is especially suitable for medium and low temperature chillers to carry cold capacity. The temperature is generally required to be controlled at 0 Below ℃, it is usually used for the low-temperature requirements of some special production lines in the industry. So, what kind of harm will the improper proportion of brine-carrying refrigerant cause to the chiller and how to measure brine concentration for the brine chiller ?


brine chiller manufacturers



The refrigerant is an intermediate substance used to transfer the cold heat generated by the refrigerator to the object to be cooled or heated. Commonly used refrigerants include air, water, saltwater, organic compounds, and their aqueous solutions; when the outlet water temperature is 0°C, the commonly used water-borne refrigerants will be frozen. At this time, a suitable refrigerant must be selected, such as saltwater, Ethylene glycol, etc., the selection principle is first that the refrigerant in the heat exchanger does not be frozen.

Salt water carrier refrigerant use temperature and ratio mass concentration table




1. The salt water concentration is too high or too low.
If the brine concentration is increased and the specific heat is reduced, the power consumption of the chiller pump of the chiller will increase, and the relative cost will also increase; if the concentration is too small to reach the standard, this may cause the heat exchanger to freeze, the unit alarm can not work normally and affects normal production. Therefore, when we use salt water as the refrigerant carrier of the brine low-temperature chiller, we must pay attention to the ratio of the brine carrier refrigerant.

2. The corrosiveness of salt water to low-temperature chillers and pipelines.
If the oxygen content in the solution decreases, its corrosiveness to brine low temperature chillers and pipelines will slow down. Based on this, we can adopt a closed salt water system to reduce the principle of contact between salt water and air, so as to reduce the corrosion of low-temperature chillers and pipelines. In addition, you can also reduce the corrosiveness by adding preservatives to the salt water to make it have suitable acidity and alkalinity.

When the density of brine carrier refrigerant decreases.
The brine-carrying agent will absorb moisture in the air during use, which will reduce its concentration and cause the freezing point to rising. Therefore, in the process of using the brine cryogenic chiller, the density of the brine should be checked regularly. If the density appears To reduce the phenomenon, the amount of salt can be supplemented appropriately to maintain the concentration of brine.

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 ...
