Heat Transfer Systems:  Universal Systems up to 400oC – ITH and ITHW Series

 ith Heat transfer systems use either thermal oil, water or water/glycol as the heat transfer fluid depending on the outflow temperature. They are electrically heated and produce a controlled liquid flow. Heating and cooling systems from the line of heat transfer systems always consist of the electrical heating module and maximum one additional heat exchanger module (cooler). In this design or also in combination with a process cooling system, a heating and cooling system is produced with an extended working temperature range.

Process Cooling Systems:  Cooling systems from -100 up to 150 °C – SUK Series

Process cooling systems are active cooling systems for the temperature control of different consumer circuits. They have a single-stage cooling circuit or two-stage cascade cooling systems and are water or air-cooled. In combination with an electrical auxiliary heater or a heat exchanger, the SUK model series offers a wide working temperature range. Depending on the application, the most varied heat transfer fluids can be used.

Process Cooling systems from -110 up to 20 °C – DV Series

DV Process cooling systems in the DV model series are systems with a compression cooling system, i.e. chilling is produced by means of electrical drive energy using a compression refrigeration process. Depending on the operating temperature range the cooling systems can be operated as direct evaporator with the most varied refrigerants and with existing external pump with varied heat transfer fluids.

Process Cooling systems from -100 up to 400 °C – KH Series


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.

Systems for the use of primary energy from -150 up to 400 °C – TR Series

Secondary circuit systems use existing energy sources, such as steam, cooling water and brine – so-called primary systems. Here, the objective is to integrate the existing infrastructure and best possible use of the thermal energy on the primary side. In this way only a single heat transfer fluid circuit is used (single fluid system) on the consumer instead of steam, cooling water and brine circuits. Important advantages arise through the use of only one heat transfer liquid: due to the seamless and reproducible temperature control throughout the whole temperature range changeover to different media is not required. Through the use of thermal oil low operating pressures prevail and the heat carrier also acts as a separating medium between the product and the environment.

Single fluid systems from -150 up to 280 °C – KP Series


In order to achieve still higher levels of purity in modern production methods, reactions are run at very low temperatures. The range of modules from LAUDA includes the Kryopac for this application. Here the cooling power of evaporating nitrogen is exploited and transferred to a liquid heat transfer fluid. Kryopac systems are secondary circuit systems which are cooled with liquid nitrogen on the primary side. For these extreme cooling applications only special low temperature heat transfer fluids are used. LAUDA developed a special technique to solve the known freezing problems. A suitable intermediate medium transfers the cooling of the low temperature nitrogen (-196 °C) to the heat transfer fluid, controlled accurately to the degree.
