Foam agents - Import export

Several million scrap refrigerator units are disposed of every year in Germany alone. The proportion of refrigeration units recycled by volume totals about 40% and is the most significant segment after consumer electronics. One particular challenge in this recycling process is presented by chlorofluorocarbons such as R 11, R 12 or R 141b, which were used for decades as foaming agents for insulation materials. Since these substances damage the Earth’s ozone layer when released, they must be removed and collected securely in a closed-system pre-processing plant. The fact that pre-processing of legacy refrigeration units always needs to be carried out in accordance with the latest technological standards means that plant operators gain a decisive advantage when working with an innovative and experienced plant manufacturer. With ERDWICH, you are assured of the latest technologically advanced solutions – even for the most demanding and safety-conscious refrigerator recycling. The...

With ERDWICH, you are assured of the latest, technologically advanced solutions: Whether you’re handling small-scale units or complex refrigeration plant: utilise the expertise we’ve gained in processing over 30 million refrigerator units. To get an idea of what we’re capable of, please see the following Case Studies. Now it’s your turn: we look forward to receiving your project enquiry!

Wound filter-cartridges Type: PP, PPW (washed) Wound filter-cartridges are depth-filter-elements, produced in a special way of winding. Newest winding-machines guarantee a constant and high quality for filter-cartridges up to 60”. The PPW filter-element is wound with a special washed yarn. Washed yarn is free of wetting agents and prevents foaming.

is a polysaccaride, formed by the microorganism Xanthomonas campestris. The basis for the fermentation process are sugary substances and nutrient salts. The molecule contains D-glucose, D-mannose and D-glucuronic acid. It is produced by mixing sodium and potassium salt. Xanthan is a creamy white powder, that is easily soluble in hot as well as cold water and forms a viscose, pseudoplastic dissolution. It is used as stabilizer, emulsifier, thickener, suspension agent and foam booster for food. Xanthan has extraordinary and very useful properties. It has alreday a high viscosity at a low concentration, it shows a stable viscosity at temperature fluctuations and is very pH-, freeze and thaw stable.
