Application Background

MMTCI Group’s environmental division develops and installs high performance filtration systems in partnership with Eclipse Magnetics in France. MMTCI, and more specifically its environmental subsidiary, develops specific filtration systems that meet the constraints of a variety of industry sectors.

As specialists in the filtration of liquids including cutting fluids and detergents, MMTCI offer complete management of reprocessing solutions. With extensive expertise regarding new technologies in the field of filtration, the business provides innovative solutions to meet the technical and financial needs of its customers.

The MMTCI Group’s environmental division worked closely with Eclipse Magnetics to offer a leading car manufacturer a method of keeping coolant clean during the manufacture of shafts for gearboxes.

The Challenge

The material machined by the car manufacturer is steel grade 27 CrMo4, which is used in turning, drilling, and deep drilling processes. Due to the nature of the machined material and the application process, the coolant used had a tendency to become saturated with particulate. This, therefore, impacted the quality of the surface finish, the efficiency of the process, and the downtime involved in rectifying the problem.

The car manufacturer’s initial situation involved a centralised media-based filtration system (threshold 340 µm) with a volume of 92 cubic meters and 800 cubic meters per hour of water. 14 machines were connected to the central filtration system. A more effective method of filtration was required to solve the problems associated with the particulate building up in the coolant.

The Solution

MMTCI Group’s environmental division installed Eclipse Magnetics high-performance filtration systems in order to recover the particles that were collecting in the coolant and effectively remove them from the process. An initial solution of two FiltraMag FM2.0+ were installed in order to protect the two machines equipped with high pressure pumps. The Filtramags were installed in parallel for a flow of 30 cubic meters per hour.

Filtramag+ is a high performance magnetic filter with full stainless steel construction. Its high intensity magnetic cores make it 100% effective for use with materials which have lower magnetic permeability, and it can be used to remove both magnetic and non-magnetic contamination. Eclipse Magnetic’s Unique Dual Flow Technology TM maximises collection capability, and its non-block, easy clean design offers rapid return on investment.

The second phase included the installation of a set of Eclipse Magnetics magnetic filters, which enabled the filtration of the full volume of fluid. This closed-circuit assembly is installed directly on the central filtration system and consists of two AutoMag AM12s, a separator drum for the evacuation of the sludge, a plunging pump, and the electric/pneumatic steering box.

The AutoMag is a fully automated magnetic filtration unit which is ideal for 24/7 machining operations. With high contamination collection capacity and an ability to handle high flow rates, the Automag was able to offer a solution for the car manufacturers’ problems with contaminated coolant, enabling the effective removal of contaminate.

Before the Eclipse Magnetics filters were installed by MMTCI Group, the machining liquid had a contaminate reading of 556 parts per million. After a week of use, this had reduced to 139 ppm, and is now less than 100 ppm.


Jonathan Michels at MMTCI said: “This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future. There is work to be done, however, with educating customers to overcome the reticence that they may have about this technology. We have to prove to them what we already know: it works!”

"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."

John Smith, MMTCI

"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."

Facilities Manager, Milacron Machines (Sub-Contract Machining)

"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."

Pat Richards, Chief Engineer at Simpsons Malt

“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”

Kenneth McRae, Principle Engineer at Vallourec

"Here at Qualflow, we base our business on a philosophy of make the product simple to use, reliable and cost-effective. Eclipse Magnetics’ neodymium magnets offer the strongest magnetic performance, and are nickel plated, making them a cost effective.."

Justin Lawler Ph.D. MBA, Chief Technology Officer at Qualflow Systems Ltd

"The Ultralift Plus magnetic lifter from Eclipse Magnetics is the perfect solution for the pick-up and transportation of the ultrasonic calibration blocks in our facility"

John Crossley, NDT Technology Lead at the Nuclear AMRC

"The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean..."
