There are a whole host of other applications for Ferrofluid. Many
of these are still at the R&D stage but some have already achieved
a degree of commercial success. Ferrofluidics carries out research
into new applications for ferrofluids both on its own and through
strategic partnerships with other companies. Other applications
areas in which ferrofluids have been used include material recycling,
power and distribution transformers, quiet solenoids, sensors and
Ferrofluid has a unique property in that its
apparent density can be increased by applying a magnetic field
to the ferrofluid. This physical characteristic creates the ability
to separate objects of different density through floatation or
sinking. Ferrofluids have been used for years in material separation
processes in the mining industries, although with limited economic
advantage. Ferrofluidics has been working with material recycling
and mining industry leaders to commercialize this application.
To enhance the economic viability of these processes, Ferrofluidics
has developed a patent-pending process for the reclamation and
reconstitution of ferrofluids. This innovation will create economic
advantage for the separation industries to enhance the existing
separation performance characteristics of the materials.
Ferrofluidics Corporation has been working in
partnership with a major manufacturer of electrical power equipment,
to develop ferrofluid for liquid-filled transformer applications.
Ferrofluids have been shown to provide both thermal and dielectric
benefits to transformers. Ferrofluid can be utilized to improve
cooling by enhancing fluid circulation within transformer windings.
Ferrofluid can also be applied to increase transformer capacity
to withstand lightning impulses, while also minimizing the effect
of moisture on typical insulating fluids. The benefits of ferrofluid
may be utilized to design smaller, more efficient new transformers,
or to extend the life or loading capability of existing units.
The introduction of a ferrofluid into a solenoid
dramatically reduces the noise level of certain equipment, such
as home care kidney dialysis machines. This in turn reduces the
need for noise suppression insulation, allowing a more cost effective
and simpler design that is more portable. In addition to the obvious
benefits of quieter operation and portability, the ferrofluid-based
solenoids make the equipment more reliable.
Sensors & Switches
The unique properties of magnetic fluid make
it a feasible technology for some sensor and switch applications.
The use of ferrofluid may enhance the motion sensitivity in some
sensing applications. Products being evaluated for ferrofluid
application include inclinometers, accelerometers and flow meters,
tilt, vibration, pressure and level sensors, and various switches.
