U.C.V.D. the revolutionary sampling method developed by Mecoil

Sampling procedures are subject to several international standards, developed and refined over the years due to the demanding requests made by the maintenance and Q.C. technicians.

The search for “root causes” of impending failures starting from used lubricating oil, has become a widely recognized reality shared by different parts, both civil (see ASTM, DIN / ISO ) and military fields (J.O.A.P. program by D.O.D. -U.S.A.).

Our long experience in the “Preventive Medicine” field of critical assets (over 30 years of practice in this discipline) made us well aware as the weak link of the entire diagnostic process lies precisely at the sampling stage.

With the introduction of the new sampling system, even though a simple idea, the life of those who work in contact with operating lubricants has become much more streamlined. 

Sampling in safety

The U.C.V.D. vessel was created to avoid the most common mistakes during the sampling approach. With oil analysis, results depend mainly on procedures related to sample collection. This is the most critical step in all the links of the chain relationship, necessary to perform the best possible tests. Independent surveys claim that the “sampling procedures” are responsible for more than 70% of the errors.

The U.C.V.D. technology

The essential point of this system, “U.C.V.D.(Ultra Clean Vacuum Device) lies in the fact that we have patented a bottle of appropriate volume, inside of which lies the vacuum. The vacuum sucks the fluid to be sampled while at the same time preventing foreign particles from the environment from falling inside the bottle. The simple process requires inserting the proper siphon tube and switching the valve on with a twist of your fingertips to let the oil flow through until it stops.

Patented system

Mecoil Diagnosi Meccaniche has patented the U.C.V.D. Thanks to the U.C.V.D. (Ultra Clean Vacuum Device) technology, an extreme level of cleanliness is guaranteed. The results? Less stress and more operational security. No mess, no bags, pumps, or syringes. Only one hand is necessary to hold the bottle. This part of the operation can also be carried out without any supervision.
