摘要
The underlying invention enables the temperature control of sensitive product streams. For example, in the pharmaceutical or fine chemical production within a disposable tube by a tube-in-tube principle. In this case, the outer jacket pipe is passed through with a heat transfer medium and the inner tube with the product flow. The modularized design allows a series connection of individual tube-in-tube elements, which increases the performance over the heat exchanger surface. Furthermore, can be introduced by the division of the outer pipe in two half-shells and corresponding clamping connections hoses of different diameters. As a result of the properties described and the mobile design, the invention is able to provide or dissipate heat in succession in a plurality of production steps, without substantially increasing the operating costs. In particular, if different process steps are already connected to disposable pipelines. The purchase of other disposable materials is not necessary and the cleaning and sterilization or the corresponding validation lapsed. This also applies to the validation of new starting materials, provided that the plastic pipe is already established. The risk of acquiring a new process operation is therefore significantly reduced.
