heating tape on pipes with aluminium tapes for better heat transfer

In Germany, in the Brandenburg region of Gröden, Schradenbiogas GmbH & Co. KG operates a biogas plant based on anaerobic wet fermentation. In this process, liquid organic waste is extracted from the agricultural sector in the form of cattle and pig manure from the region, as well as solid organic waste, waste from kitchens and canteens, and processed in various process steps to produce biogas with a methane content of up to 69%.
On the one hand, this biogas is converted into electrical and thermal energy by a ccombined heat and power unit. On the other hand, the biogas is refined into a biomethane in a processing plant.
The water required for process operation as well as the substrate distribution must be prepared during operation and at standstill for winter operation.
Especially when pipes run over long distances in the open, there is a risk that they will freeze if the flow stagnated in winter.
As freeze protection, an electrical trace heating system with self-limiting heating tapes from Quintex was installed along various pipe sections.
The self-limiting heating tape adjusts its heating power automatically and outputs a higher or lower output depending on the ambient temperature.

Further advantages are:

No risk of overheating
Easy to install
Economic operation

The required heat demand for the various pipe sizes up to DN150 was calculated by Quintex, so that even at extreme minus temperatures, always frost protection is ensured on all relevant pipeline sections .

The needs-oriented and economical operation is carried out via the in-house building control technology of the company Schradenbiogas GmbH & Co. KG.

The pictures show pipeline sections in the area of ​​"hygienisation" with heating strip on the long side and overlapped with aluminium adhesive tape, for an optimal and two-dimensional heat transfer to the pipeline.

We made a little video to show the ease of use of overpressure system in hazardous areas for un-approved devices. It is the easiest way to bring YOUR device into hazardous area too. The explosion protection at the "overpressure system 2.0" is realized by operating a non-explosion-protected equipment in a protected enclosure. This housing is protected by a durable pressure with air or an inert gas prior to penetrate the enclosure
