High ambient temperature results in that the intelligent temperature controller of S&A water chiller displays 30℃, and it is mistaken for failure of cooling

Posted on

Yesterday, an Indian laser customer made a mistake and wasted a sum of maintenance fee.

When using the S&A CW-5000 water chiller to cool CO2 laser tubes, the customer found that the control panel of the chiller displayed 30℃, and he mistakenly assumed that the chiller couldn`t cool any longer. So he asked local maintenance personnel to supplement refrigerant, afterwards, he contacted S&A.
After we learned the whole thing, we finally found the reason why the water temperature of the chiller rose continuously.
The factory setting of S&A CW-5000 water chiller temperature controller is intelligent mode. Under intelligent mode, water temperature will change with ambient temperature (generally, water temperature is 2℃ higher than ambient temperature). So, when the customer`s workshop temperature exceeds 30℃, the water temperature of the water chiller will fluctuate around 30℃. At this point, it is only needed to turn the mode of the water chiller temperature controller to constant-temperature mode, so as to set water temperature manually, such as maintaining the temperature at 25℃, then the problem can be solved easily.
Warm prompt: If the water chiller has any abnormity, please contact the after-sales personnel of S&A timely.
Thank you so much for your support and trust in S&A. All S&A water chillers have passed the certification of ISO, CE, RoHS and REACH, and the warranty period has been extended to 2 years. Welcome to purchase our products!
