The technology also leads to a better value for metal recovery than systems involving thermal desorption or incineration, which alter or damage the metals. Limitations Wood and cardboard in Askarel equipment are removed and sent for incineration rather than being decontaminated. The equipment is mobile and requires three to six 14 m flatbeds for transport, depending on the extent of the work to be carried out. Installation requires a flat surface of 30 m x 40 m and can take from two to seven working days. The same time is required for disassembly.
Workers wear personal protection equipment when performing certain tasks.
A 130 kW power source is required, as well as a supply of fuel oil. Access to the work area is strictly restricted to the personnel and their entries and exits are controlled. Equipment containing fluids are sealed and placed in spill pans to prevent any spill or loss of fluid. Transformer treatment starts with an initial cleaning step, called the degreasing stage. Solvent circulates in closed circuit, allowing PCBs to be extracted.
