New Optimal Oil Filtration (OOF): Keeping an Eye on the Oil that Keeps Your Foundry Equipment Running


DISA has introduced an Optimal Oil Filtration (OOF) unit for its DISAMATIC® moulding line. Developed as a new feature on the DISAMATIC D3, the OOF was designed to provide real-time information on the condition of the oil in the hydraulic system – to control contamination and filter out particles.

An immediate benefit of the new system is reduced equipment maintenance.The long-term advantages include the prevention of equipment failure, reduced environmental impact and extended component life.

Lars Hjelm, Global Product Manager at DISA, comments: “The OOF goes beyond removing particles from oil. It provides a constant, real-time overview of the status, quality and purity of the oil currently used to run your foundry equipment. It extracts all contamination and particle information and makes it available to the foundry operator via a simple and easily understandable display. The OOF allows foundry operators to sleep well at night, because it ensures optimal performance of your equipment at all times.” 

Contaminants lead to system failure

The overall contamination control of the OOF is crucial for ongoing equipment health – as is the integrated filter element for filtering out particles introduced by hydraulic components and the foundry environment. 

A major source of declining oil performance is contamination with water. Lars explains: “Water in oil is an almost invisible contaminant with highly damaging effects on system efficiency – both with regard to the oil itself and the foundry components it supports in their function. 

“Water reduces the ability of the oil to lubricate, which leads to higher operating temperatures, resulting in oil degradation products such as oxidation by-products, resin and varnish. Together with particles, oil degradation products are responsible for micro-pitting on component surfaces. Another well-known effect of water in oil is corrosion. If water in oil is not removed effectively, equipment lifetime is quickly reduced”. 

Going real-time, for peace of mind

Another advantage of in-line, real-time monitoring of oil is the impact on maintenance. 

Lars: “Instead of spending a vast amount of time analysing the purity and quality of your oil, as well as an equally vast amount on changing the oil as a preventive measure, the OOF offers a real-time status, enabling you to change oil only when necessary. 

“Taken together, all the benefits of the OOF can dramatically improve the reliability and lifetime of your moulding equipment and boost your daily foundry operations.”

The OOF is introduced to the market as a new feature on DISAMATIC D3. Retrofit solutions are planned for most DISA moulding lines, with only minor adjustments necessary.
