Stable humidity and temperature are a fundamental requirement for the production of high-quality products, especially when it comes to repeat jobs. Heat sources have a negative effect on the fragile balance between relative humidity and temperature.
In order to counter this effect, water-cooled peripheral units are widely used these days. Based on 40 years of development and project experience, technotrans ensures the reliable supply of these units with cooling water. The productivity in the production area increases continuously.
Water cooling has been the standard method for motors in automotive engineering for a long time. However, water can also absorb the waste heat of the machine and withdraw it from the production area. Compared to air cooling, water cooling requires only small pipe cross-sections for a high level of
performance, which is due to the special physical characteristics of water.
The cooling of highly precise machines is indispensable these days owing to their power density. Studies show, for example, that the cooling of drive motors and cooling lubricants accounts for up to 50% of the total power input. One major cause: every machine has its own cooling system, thereby representing an isolated supply point. Our solution: a central system combines these isolated supply points in a cluster and aligns the capacity reserves by way of a superordinate intelligent control system.
On the basis of water-cooled individual units or a central system with the appropriate free-cooling option and an external freecooler (air/water heat exchanger), low outside air temperatures are used to cool the central cooling circuit and the connected individual units „directly“.
The free cooling function starts at external air temperatures below the setpoint of the process to be cooled and takes on more and more of the compressor refrigeration as the outside air temperature continues to decrease until the compressors shut down completely.
So an installation in Berlin with a process temperature of 20 °C can operate exclusively with free cooling for 60 % of the time. Therefore energy is saved very efficiently, as a refrigeration unit is not required.
