Recirculating Chillers: Vital for Laboratory Temperature Control

Recirculating chillers are essential equipment in many laboratories, providing precise temperature control for a variety of applications. These chillers circulate a coolant through a closed loop, ensuring that the temperature of the process or equipment remains stable and within the desired range. In this article, we will explore the importance of recirculating chillers in laboratory settings, their advantages, applications, and the market trends that are shaping their development and adoption.

How Recirculating Chillers Work

Recirculating chillers operate on the principle of vapor compression refrigeration. The system circulates a coolant, typically a mixture of water and glycol or a specialized fluid, through a closed loop. The coolant absorbs heat from the process or equipment it is cooling, and this heated fluid is then passed through a heat exchanger where it releases the heat to the refrigerant.

The refrigerant, now carrying the absorbed heat, is compressed, which increases its temperature and pressure. It then flows through a condenser where it releases the heat to the environment or a cooling medium. The cooled refrigerant then expands back into the evaporator, where the cycle begins again, providing continuous cooling.
