HYFRA TRK 50-EF-S Kühlmittelanlage

Industrial coolant or oil purification system

Belt filter system for coolant purification with cooling unit

The system was removed from a fully functional HERMLE C 1200 U machining center.

This system is a central unit for the cleaning and conditioning of coolants (KSS) or oils, as used in metal-cutting production processes (e.g. grinding, milling, turning). It combines mechanical filtration (belt filter), fluid storage, and temperature control via an integrated cooling unit.
