Regular monitoring of the process media is the key to consistently high product quality. For this reason, all process media are checked at specified intervals and if necessary purified or exchanged.

Amongst others, these include:

•     Quenching oils (water content, degree of contamination)
•     Hardening salts (cyanide /cyanate content)
•     Washing agents (detergent concentration, oil content, contaminants)

There are extensive chemical analytical processes available in Hanomag Heat Treatment Group, which are carried out according to instructions by the laboratory staff at the respective sites. Further, regular analyses are carried out in external laboratories by certified specialist companies.
