SPECIAL CLEANERS

SERVIDUR special cleaners are used to clean components before and after heat treatment. Their premium quality meets the high specific demands heat treatment shops make on the condition of the cleaned workpiece surface. 

When used before heat treatment, almost all residues are safely removed that could interfere with thermochemical diffusion processes or with the heat treatment system. When used after quenching the quenching oil is specifically removed. Optimal results are guaranteed by the special adaptation of the cleaners to the Burgdorf quenchant program. 

The water-based cleaners ensure a long bath life, low consumption and cost-effectiveness due to their outstanding degreasing effects in conjunction with excellent demulsifying properties. 

Burgdorf furthermore offers a range of highly effective cleaners based on hydrocarbons and modified alcohols that have been approved by renowned plant manufacturers such as EMO and Dürr. 

All our SERVIDUR cleaners are state of the art in terms of the latest regulations and laws in regard to environmental, health and safety aspects and will, since they are highly effective, contribute to low process costs.
