German company BHS-Sonthofen GmbH, has developed a complete solution for the economical recycling of refrigeration units combining mechanical crushing of the units with thermal-catalytic oxidation of the refrigerants and blowing agents.
The only end products of the process are the shredded solids and carbon dioxide, as well as a saline solution.
The BHS method renders several superfluous steps required by other methods, which cuts the costs of processing considerably.
BHS Rotorshredders have been proven in the mechanical crushing of refrigeration units in everyday operations in a recycling company in Denmark.
Together with German company Kopf Anlagenbau GmbH, BHS has now developed the plant technology further especially in the area of gas purification, leading to a total of four patent applications.
Kopf Anlagenbau is an experienced supplier of everything needed for wastewater and process water treatment and the purification of industrial exhaust air and gases – especially in the fields of catalytic, adsorptive and absorptive gas purification.
According to both companies the resulting complete solution makes the recycling of refrigeration units significantly more economical than with previously used methods, thus setting a new industry standard.
The mechanical crushing separates the solids according to material type, while the catalytic transformation of the refrigerants and blowing agents transforms more than 99 per cent of all gaseous emissions into harmless substances such as water vapor, carbon dioxide, and saline solutions.
The IC process is a new technology for processing refrigeration units containing CFCs and hydrocarbons.
It is especially attractive at relatively high plant output rates, as the operating costs are significantly lower than with the methods normally used before.
The plants can process up to 150 refrigeration units per hour.
