Quenching bath Q 400 D with manual charging aid

Oil cooler as additional equipment

The oil and water quench baths are combined within a single housing and separated by a sheet metal wall in the Q 200 D, Q 400 D and Q 600 D combination baths. The oil quench bath is slightly preheated by the heated water bath. A splash pan is installed in front of the combination bath. Charging aids are available as additional equipment. The Q 200 D combination bath comes with a charge carrier, for models Q 400 D and Q 600 D must be ordered extra. For greater quenchant performance, the baths can be equipped with oil coolers.
