How to choose the right chiller for your process

Heat is a single common by-product of today‘s manufacturing machines that include the advanced automation technology required for both high speed operation and high precision. Components such as spindle motors, variable frequency drives, laser and x-ray sources all require cooling to operate properly and reliably – most often in the very adverse manufacturing environments.

Water chiller can help us reduce the heat generated in the production process, lower the temperature, so as to increase product output, improve product quality, and protect our production equipment. How to select the chiller? Refer to the following aspects:

1. Cooling capacity

That is the cooling capacity of the chiller. According to the photoelectric conversion efficiency of the laser equipment, calculate the heat generated by it, and then match and select the appropriate industrial chiller. Different types of chillers will have differences in this aspect. If you are not familiar with this aspect, welcome to consult the professionals of Cooling Times.

2. Temperature control accuracy

This indicator is entirely from the requirements of the laser. For semiconductor lasers, the temperature control accuracy must be ±0.1℃. This requires the compressor to predict the law of temperature changes and adapt to the load changes. Generally, it is impossible to use a water chiller with an integrated temperature control module To this point. Of course, for CO2 lasers, the temperature requirement is ±2℃ to ±5℃, and most of the dedicated water coolers on the market can do it. However, Cooling Times is currently one of the few laser chillers that actually reach ±0.1°C.

3. Water flow and booster pump head

The cooling capacity represents the cooling capacity provided by the compressor, and the water flow represents the ability of the chiller to take away heat. This causes the phenomenon that everyone often sees: a chiller with a nominal cooling capacity of 1000W is connected to an 80W glass tube, and the chiller It shows 25℃, but the laser tube is very hot; in fact, it has no application effect.

Of course, in addition to these aspects, the selection should also consider thermal efficiency and water volume, water quality requirements, water filtration and water circulation system materials... etc.
