Temperature Control Systems

Temperature control is a very important aspect in the planning and production of the plant tailored to your company, as heating and cooling times often take up a considerable part of the complete batch time. To achieve maximum efficiency and profitability, the temperature control system must be tailored to your needs and of corresponding technical design. The standard temperature control systems include electric heating systems as well as steam connections, cooling water systems and steam plants; gas heaters and hot water generating plants are also possible. At high temperatures, thermal oils can also be employed as a heat transfer medium. Right from the design of suitable production areas, SEEFRIED Verfahrenstechnik GmbH can be there to support and assist you in aligning these to the planned production plant.

Tempering systems are required to supply heat to or dissipate heat from the vessel. This plays a central role in the production process. Product masses must be heated and/or cooled to or kept at certain temperatures, in order to ensure optimal flow and processing properties. The tempering system should be designed in such a way that the handling of sensitive substances is possible. With the awareness of possible thermal damage, tempering systems should be integrated into your agitators, which enables an individual, infinitely variable and time-independent temperature adjustment. At the same time, you can carry out temperature control and adaption whenever necessary. By means of a well-designed temperature control system, it is also possible to adapt the flow behaviour and flow rate to individual requirements and regulations at any time.

Temperature control systems can be connected to the homogenising mixers via either primary or secondary circuits. The advantage of primary circuits is generally fast heating-cooling cycles, but disadvantages can arise in the area of temperature control (temperature flashovers / temperature drops), as well as a normally higher consumption of heating-cooling media. By means of heat exchangers, secondary circuits have, as a closed system to the process plant, extremely precise temperature control, the heating and cooling times can, however, be longer. In the area of cooling, buffer tanks, with integrated chiller and as a closed system, can drastically reduce the consumption of waste water, thus not only protecting the environment, but also increasing profitability.

Conventional heating and cooling media are, for example, water, steam or thermal oil for particularly high temperatures.
