HYFRA TRK 50-EF-S Kühlmittelanlage

Industrial coolant or oil purification system
Band filter system for coolant filtration with chiller unit

The system was dismantled from a fully operational HERMLE C 1200 U machining center.

This unit is a central system for cleaning and conditioning coolants (KSS) or oils used in metal cutting operations (e.g., grinding, milling, turning). It combines mechanical filtration (band filter), fluid storage, and temperature control via an integrated chiller.
