Problem solving

We offer a complete range of products and services for filtration, but above all the advice and technical assistance necessary to identify the most advantageous treatments for our customers, because they can improve the performance of the machines and, thanks to the programming of maintenance plans, hoc, help prevent breakdowns and arrests in production. La Ricambi Udinese offers hydraulic advice on filtration and similar, retrofitting sizing on filtration in pre-existing hydraulic systems.

FILTER DIMENSIONING

The problem

A customer of us, asked us to replace some coarse filters (metallic housings with an hand-made inner modified filter element) applied in lubricating circuits on big compressors used in a refrigeration plant. He wanted to replace them with new filters , utilizing standard cleanable filter cartridges with a better filtration ratio, dimensioning them in a way to obtain a longer cartridge life.

The cause

We dimensioned the new filter system choosing a four time filtration area to elongate the cartridge working life. What we didn’t keep in mind was the filtered fluid compatibility. We discovered that the lubricating oil, coming in contact with ammonia pumped from the compressors, tended to damage the filter cartridges.

The solution

We solved this problem by using the same filter cartridges but realized entirely in stainless steel, with bottom ends welded, not glued. After three years, the system is still running with no problems.
