KH process cooling systems

Cooling systems from -100 up to 400 °C

Continually changing methods in the manufacture of the most varied products demand an ever increasing scope of temperatures. Intensely exothermic batch processes can only be controlled with highly dynamic thermostatic systems, such as the heating and cooling systems from LAUDA. The Kryoheaters fulfill the high requirements of thermostatic systems and already offer the modern heat transfer technology. The technology of Kryoheaters covers a range from -100 up to 400 °C. The field of application is currently only restricted by the physical properties of the available heat transfer fluids.
