Coolant Chillers
More Efficient Heat Transfer Systems
Using direct expansion of the refrigerant to exchange heat with the target control element, the heat exchange capacity is five times that of fluid heat exchange.
Coolant Chillers Overview
Coolant chiller is a series under the direct expansion system. Unlike indirect heat transfer, such as liquid cooled and air cooled, it allows direct heat transfer by evaporating the refrigerant output into the equipment that requires heat transfer. It is very efficient because it does not require heat transfer through a fluid. Coolant chiller is very suitable for use in a scene of a small heat exchange area but large heat exchange capacity, such as process equipment cooling, laser cooling, etc.. It can avoid equipment damage caused by thermal stress. LNEYA has been specializing in refrigeration for 30 years, providing you with precise temperature control between -150℃ and +350℃. If you need an ultra-low temperature chiller, LNEYA is your ideal choice.

Coolant Chillers Advantages
- High efficiency: LNEYA coolant chiller can evaporate the refrigerant output directly into the interior of the target cooling equipment, and its heat transfer capacity is more than 5 times of the fluid heat transfer. In addition, we use high temperature cooling technology. Take thermal chuck as an example, it takes only 2 minutes to cool down from 220℃ to 25℃, and 6 minutes from 25℃ to -60℃. Waiting time is saved.
- Compact design: Coolant chillers are very compact due to their modular design. Therefore they are very small in size and have low space requirements. The volume of standard model thermal chuck can be 556537, you can easily put it on the table to use.
- Flexible: All process chillers can be added with casters, you can move them to various places as needed. When you need to secure it somewhere, you can use the locking mechanism on the casters to keep it stable.
- Personalization: The coolant chiller Series has a variety of products that offer different capabilities. If a standard model doesn’t work for your application, we offer customization. We can customize the size, temperature range, temperature control accuracy, cooling rate, cooling capacity, voltage and power supply, and other parameters of the process chiller, if you need them.
Coolant Chillers Importance
Reduce operating costs: The structure of the direct expansion coolant chiller is simpler than that of the liquid chiller. Because it does not require cooling water, it does not need to be equipped with cooling water pipes and water pumps. It can reduce the initial investment and later maintenance costs. In addition, the direct use of refrigerant cooling is more efficient and consumes less energy.
Save space: Compared with liquid chillers, direct expansion coolant chillers do not have a complex cooling water circulation system, so it has a more compact structure and occupies less space. The direct expansion system can be designed to be very small and is suitable for use in scenarios with limited space, such as laboratories.
Accurate temperature control: The direct expansion chiller adopts direct heat exchange, so its response speed is very fast. Moreover, combined with PT100 and PID control algorithms, this enables it to accurately control the evaporation temperature of the refrigerant.
Coolant Chillers Applications
Laser equipment cooling: Laser equipment generates a lot of waste heat during operation. If it cannot be dissipated in time, it will not only affect the work progress, but also damage the equipment. The coolant chiller can quickly take away the heat it generates and stabilize the working temperature of the laser equipment to a specific value.
Optical equipment: Optical equipment such as microscopes and spectrometers can only operate normally at a certain temperature, otherwise it may affect the accuracy of the experimental results. The direct expansion system can accurately control the temperature of these optical equipment.
Laboratory: Some temperature-sensitive experiments require strict control of the experimental temperature. The temperature control accuracy of the direct expansion coolant chiller is as high as ±0.3℃, which can meet the requirements.
Semiconductor manufacturing: Semiconductor manufacturing has extremely strict temperature requirements, and many process flows need to be carried out under specific temperature. For example, etching, ion implantation, cleaning, packaging, testing, etc.

FAQ
A coolant chiller can evaporate the refrigerant output in the refrigeration system and enter the target control element for heat exchange, with higher heat exchange efficiency.
You need to consider the boiling point, freezing point, latent heat of evaporation, specific heat capacity, ozone depletion potential, global warming potential, price, applicable temperature range, and other data of the coolant.
You need to regularly check the refrigerant amount and pressure, clean the evaporator and condenser, check the electronic control system and temperature control system, etc.
