Industrial filtering systems

Cosema is a company dedicated to the machine tool industry, designing and manufacturing systems for the filtration of coolants and systems for swarf handling.

Since its corporation in 1952, Cosema has been the Italian market leader, when the company began by producing magnetic separators and extended its activities with the development of gravity filters with disposable media, self-cleaning drum filters, a range of hydrostatic filters, and, more recently, with the production of centralized systems for swarf handling, de-oiling and storage of chips.

Gravity filter

Flow rate from 40 to 1.800 l/min

CHARACTERISTIC
Cosema gravity filter clarifiers are suitable for cleaning coolant used in the machining of a wide material range.
The filtration degree can vary from 15 to 50 micron average, depending on which kind of paper roll is used.
This system is completely automatic.

SERIES
- FB, standard gravity filter series, for flow rate from 40 to 500 l/min
- FBL – GD, large gravity filter series, for flow rate from 300 to 1.800 l/min

Combined gravity filter

Flow rate from 40 to 750 l/min

CHARACTERISTICS
Gravity filter clarifiers combined with magnetic separator are extremely suitable for cleaning coolants contaminated with ferrous and/or non ferrous particles.
The dirty coolant is first processed by the magnetic separator unit, which removes the most of the ferrous particles.
Then, the liquid passes through the gravity filter clarifier, which realizes the requested filtration degree.

SERIES
- AM for flow rate from 40 to 500 l/min
- AML for flow rate from 300 to 850 l/min

Hydrostatic gravity filter

Flow rate from 250 to 1.200 l/min

CHARACTERISTICS
The working principle of FSP hydrostatic filters is similar to the flat gravity filters.
The main difference is the high hydrostatic load, which allows to clean similar coolant quantity with a reduced floor space requirement.
The filtration degree varies from 20 to 50 micron average, depending on which kind of paper roll is used.
The system is completely automatic.

SERIES
- FSP C 2009 for flow rate from 250 to 1.200 l/min.
For applications with neat oils, flow rate can vary depending to the oil viscosity.

Self cleaning drum filter

Flow rate from 100 to 1.500 l/min

CHARACTERISTICS
Thanks to the high hydrostatic load, the self cleaning drum filter FTR allows to treat a large quantity of coolant liquid with a reduced filtration area.
The system is compeltely automatic and self cleaning, which do not require any disposable media.
A flushing system is activated when the filter fabric is choked.
In the meanwhile, the supporting drum is rotated in order to eliminate the swarf residual from the bottom of the filter.

SERIES
The FTR series is composed by 5 different filter sizes, for flow rate from 100 to 1.500 l/min

Vacuum filter

In addition to the standard filtration system, Cosema projects and produces centralized filtration system which can serve multiple machines tool, or also whole production facilities.
The vacuum band filter mod. FD allows to reach high filtration degree, thanks to the greatest and technological solutions adopted.

ADVANTAGES
- Reduced maintanance operations and time on machines tool
- High quality and temperature control of coolant liquid
- Reduced disposal cost
- Reduced overall size and workshop footprint, low enviromental emission
- System completely automatic
- Self cleaning version available
