What is a recirculation chiller used for?

A recirculation chiller is laboratory equipment that is a high-efficiency closed cooling system used in various external cooling applications. These devices are especially ideal for laboratory applications that require continuous use.

These equipment provide a consistent and reliable source of liquid refrigerant for refrigeration in laboratory, clinical or industrial applications. A recirculating chiller can reach temperature ranges from -25 ยฐC to 130 ยฐC (therefore some may act as heaters as well). Digital PID temperature controllers ensure that the recirculation cooler reaches the desired temperature accurately and quickly.

What is the function of a recirculation cooler?

The primary function of a recirculation cooler is to remove mechanical or electrical heat operating under the principle that the temperature of an object or system is controlled by the flow of heat in or out. They are commonly used to provide constant low temperature conditions for inspections, chemical, biological and physical experiments to be carried out at low temperature, mainly employed in the field of medicine, food processes, chemical industry and teaching in universities and research institutes.

Among the main common characteristics of recirculation chillers are

  • Closed circulation system can prevent cooling
  • medium evaporation and pollution, save energy.
  • The circulation system is equipped with a filter, which keeps the cooling medium clean and prevents instrument clogging.
  • They have a built-in liquid level monitor, liquid level inside
  • the bathroom can be checked visually.
  • The circulation system is equipped with gage, it shows the pressure of the circulation system.
  • Most recirculation chillers as mentioned above can operate at temperatures between -25 ยบC to 130 ยบC.

How does a recirculation cooler work?

A recirculation chiller works by incorporating high-pressure flow refrigerant circulation to accelerate the process of removing heat from an object. These systems consist of: a compressor, a condenser, a thermostatic expansion valve and an evaporator. And the cooling process starts when you pump the refrigerant gas into the compressor and it becomes a gas at high temperature and pressure. This gas then travels to the condenser where air or ambient water takes heat from the refrigerant and condenses it from gas to liquid.

Later in its liquid state, the coolant passes through the thermostatic expansion valve where pressure and temperature decrease, causing the fluid to evaporate and turn into gas. When the gas condition returns, the refrigerant is returned to the compressor and the process begins again. Because it is a continuous service, recirculation chillers do not waste any refrigerant or water during the entire process. It is important to note that this process may vary slightly depending on whether the recirculation chiller has a water or air cooled condenser.
