Steinhardt® DILLIGENT CARETEC

Lubricant coolant maintenance
– without chemicals –
safe, efficient, durable

The Challenge

Lubricant coolants are largely used in cutting production. The addition of biocides or disinfectants is frequently necessary in order to maintain the hygiene of the coolants. By law, a risk analysis is required laying down the protective measures which must be taken to safeguard work processes and health. Good grade lubricant is the key to problem-free and superior quality manufacturing processes. Waste disposal is carried out by specialists and is a significant cost factor. Negligent  handling of lubricant coolants can result in major risks for production, health and the environment.

The Solution

The Steinhardt® DILLIGENT CARETEC uses innovative hydro-mechanical technology for the effective, environ-mentally and health-friendly treatment of lubricant coolants. Pollution is treated reliably and re-contamination prevented. Long years of experience and expertise in the field of water treatment have been invested in the development and application of DILLIGENT cavitation technology. The compact units are integrated into existing machinery or the central plant and operate fully automatically with no additional chemicals.

The Way

The DILLIGENT CARETEC ‘s operation is based on physical active principles and is chemical-free. A partial flow of coolant passes through the DILLIGENT CARETEC unit for treatment. Bacteria are mechanically destroyed and removed from the water by oxidation, achieving an overall improvement in the quality of the lubricant coolant. An appropriate filtration process further increases the degree of impurity removal. Re-contamination is effectively prevented and the service life of the lubricant coolants significantly lengthened. The CARETEC unit can be exactly adapted to existing system volumes and is suitable for either permanent or intermittent operation.
