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...

One particular challenge in the refrigerator 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. 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!

The application characteristics of R134a are analyzed as follows: 1.R134a has a global warming potential (GWP) of 0.25 and R22 of 0.36, both of which are greenhouse gases. 2.the ozone depletion potential (ODP) of R134a is 0 and R22 is 0.06. This is the reason why R134a has become an environmentally friendly refrigerant. 3.the specific volume of R134a is 1.47 times that of R22, and the latent heat of evaporation is small, so the refrigeration capacity of R134a unit is only 60% of that of R22 unit. Calculated according to the price of unit cooling capacity, the price of the R22 unit is about 60% of that of the R134a unit. 4. the thermal conductivity of R134a is 10% lower than that of R22, so the heat exchange area of the heat exchanger of the R134a unit needs to be larger. 5.R134a has strong water absorption, which is 20 times that of R22, so the dryer in the unit system has higher requirements to avoid ice blocking.

Performance Standard : API CJ4/CI4/CH4 SAE 5W40 is a fully synthetic high performance heavy duty diesel engine oil that helps towards long engine life while providing long drain capability for diesel engines operating in severe applications. SAE 5W40 gives excellent performance in modern low emission engines, including refrigerated units, as well as older, well maintained engines. SAW 5W40 is recommended for use in a wide range of heavy-duty applications and operating environments found in the on road transport and off road mining, construction, and agricultural industries. The excellent performance of 5W40 is the result of extensive cooperative development work with major equipment builders and application of advanced lubrication technology. As a result, this product meets the requirements of some of the latest API, ACEA, JASO, and Global industry specifications for diesel engine oils, as well as the requirements of many major American, European, and Japanese engine...
