Refrigeration units

BHS IC process sets new standards in technology

In recent years, a key part of our development work has focused on enhancing the technology for recycling refrigeration units. We now set new technical standards in terms of throughput rates, not to mention operating costs, with the "IC process". With our new catalytic technology, we have drastically reduced the complexity of gas purification.

We recommend our large RS 3218 Rotorshredder for recycling refrigeration units. The machine features a feed opening that can accommodate the most common large appliances. This shredder can handle throughput rates of 150 units per hour. Over 50,000 units can be processed with one set of impellers. This machine ensures clean, selective separation of composite materials and reliable purification of polyurethane foam.

Thanks to the IC process, environmentally hazardous refrigerants and blowing agents do not need to be treated by freeze condensation or activated carbon filtration. Costly external disposal of the condensed gases is also eliminated. Instead, the refrigerants and blowing agents that are released during the process are extracted, catalytically treated and converted into carbon dioxide and a saline solution. Optionally, the refrigerants and blowing agents can also be converted during gas treatment to marketable chemical feedstocks, hydrochloric acid and an alkali-metal fluoride solution. This innovative new system eliminates the need for costly inerting in the crushing unit and the use of liquid nitrogen in the gas treatment process, thereby significantly reducing the recycling costs per refrigeration unit.

This new technology for treating blowing agents also enables you to operate a combined recycling plant for refrigeration units and e-scrap with high throughput rates.
