Introduction to Brine in Refrigeration

Brine, a solution of water and salt (commonly sodium chloride or calcium chloride), plays a crucial role in refrigeration systems. It serves as a secondary refrigerant, transferring heat efficiently while remaining non-volatile. But what is brine in refrigeration systems, and why is brine used in refrigeration? Brine solutions are ideal for achieving and maintaining low temperatures, making them indispensable in industrial applications. They are especially effective in systems that require consistent, extremely low temperatures over extended periods.

Brine Chillers: Overview and Applications

Brine chillers, also known as centrifugal chillers and plate chillers are specialized refrigeration systems designed to cool brine solutions. These systems are widely used in industries like chemical processing, food and beverage production, pharmaceuticals, and dairy. Brine chillers cater to a wide temperature range, making them versatile for both moderate and extremely low-temperature applications. Whether you need a low temperature brine chiller or an extremely low temperature brine chiller, these systems ensure precision cooling for various processes.


Some common applications of brine chiller systems include:

  • Ice production in fisheries
  • Cooling processes in chemical plants
  • Dairy and meat processing
  • Preservation in cold storage facilities
  • Heat transfer in thermic fluid systems

At Metro Refrigeration Industries, we provide end-to-end solutions for these applications, leveraging advanced technology and decades of expertise.

Types of Brine Chillers

Centrifugal Chillers

Centrifugal chillers use a high speed impeller to compress the refrigerant, making them efficient for large scale brine cooling system applications. They are suitable for environments requiring significant cooling capacity and consistent performance. Centrifugal refrigeration systems are commonly utilized in industries requiring reliable and high capacity cooling solutions.


Plate Chillers

Plate chillers are compact and efficient, using thin metal plates to transfer heat between the chiller brine and refrigerant. They are ideal for applications requiring quick cooling and a small footprint.

Screw Chillers

Screw chillers use rotary screw compressors to achieve efficient cooling. These systems are highly reliable and versatile, capable of handling varying cooling loads with ease.

Brine chillers can also be classified based on their cooling configurations:

  • Air Cooled Screw Chiller: Suitable for areas with limited water supply, requiring minimal infrastructure.
  • Water Cooled Screw Chiller: Ideal for locations with a stable water source, offering higher efficiency.
  • Air Cooled Centrifugal Chiller: Designed for outdoor installations, providing effective cooling without the need for water.
  • Water Cooled Centrifugal Chiller: Perfect for high-capacity applications, ensuring reliable performance with reduced operational costs.

How Does a Brine Chiller Work?

To understand how does a brine chiller work, we must delve into their core components and principles. A brine chiller refrigeration system typically consists of the following:

  • Evaporator: The refrigerant absorbs heat from the brine solution, causing it to cool.
  • Compressor: The refrigerant is compressed, raising its pressure and temperature.
  • Condenser: Heat from the refrigerant is released into the atmosphere or another cooling medium.
  • Expansion Valve: The refrigerant is expanded, lowering its pressure and temperature, ready to absorb heat again.

The brine chiller cooling system cycle is a continuous loop that ensures consistent cooling. Brine water chillers can achieve precise temperature control, making them suitable for critical industrial applications. Metro Refrigeration Industries offers robust systems designed for efficiency and reliability.

Brine and Its Role in Cooling Systems

Brine is an antifreeze solution that can be cooled far below the freezing point of water. It is used in brine refrigeration systems to achieve and maintain sub-zero temperatures. The brine solution’s salt content prevents freezing, ensuring efficient heat transfer even at extremely low temperatures. This property makes brine indispensable for various industrial applications requiring precision cooling.

Brine Refrigeration System vs. Water Chillers

While both brine chillers and water chillers serve similar purposes, their operational mechanisms and applications differ:

  • Water Chillers: Limited to temperatures above freezing (0°C).
  • Brine Chillers: Designed for sub-zero temperatures, leveraging brine’s antifreeze properties.

This distinction makes brine cooling systems indispensable for industries requiring ultra-low temperatures, such as cold storage and chemical processing. Metro Refrigeration Industries, a leading brine chiller manufacturer, ensures superior performance in both categories.  

Industrial Applications of Brine Chillers

  1. Ammonia Brine Refrigeration: Ammonia, as a primary refrigerant, is commonly paired with brine in industrial refrigeration systems. Ammonia brine refrigeration is highly efficient, environmentally friendly, and cost-effective.
  2. Thermic Fluid Systems: In thermic fluid heat exchangers, brine serves as a secondary cooling medium, enhancing heat transfer efficiency in critical industrial processes.
  3. Brine Solution for Cooling: Brine’s unique properties make it suitable for chilling in food processing, breweries, and meat storage facilities.

Metro Refrigeration Industries provides customized solutions for these applications, ensuring optimal performance and energy savings.

How To Measure Brine Concentration For The Brine Chiller

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 ?

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.

How to measure brine concentration for the brine chiller ?

Salt water carrier refrigerant use temperature and ratio mass concentration table

For more Oxidation Chiller Manufacturer and Supplierinformation, please contact us. We will provide professional answers.

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.
