Process cooling units SUK/DV
Process cooling units use an active refrigeration system, i.e. refrigeration is produced via an electrical drive motor driving a compression refrigeration process. Depending on the working temperature range these cooling units can be operated with most heat transfer fluids. If heating is also required, the high vapour pressure of water based heat transfer fluids has to be taken into consideration. Synthetic or silicone based thermal fluids are recommended when working in a wide temperature range.
Only refrigerants which are non-toxic, free from chlorine, ozonefriendly and comply with the Montreal protocol are used. Chlorinefree H-CFC refrigerant substitutes, like for instance R 404A, R 410 etc., have been proved to be good and LAUDA use them with much success.
There is still a demand on research and development and therefore LAUDA regularly test and evaluate new refrigerants including natural ones as and when they become available.
