IFD cutting costs by tapping
scientific
process utilized by racing industry
INDIANAPOLIS – The Indianapolis Fire
Department (IFD) is using a scientific process known as “cryogenics” to
help cut costs on fire truck maintenance. Cryogenics, the branch of science
dedicated to the freezing of objects to favorably alter their molecular
structure, is often used by the racing industry to enhance performance and
increase the life of mechanical parts. This treatment is being applied to
the braking systems of IFD’s fire trucks.
Once applied to all 60
fire trucks in operation, the process should save IFD an estimated $48,000
per year.
Indianapolis Fire Chief
Louis Dezelan praised the efforts of IFD manager of fleet services, Captain
Dudley Taylor, who lead the effort to apply cryogenics to truck braking
systems.
“Our firefighters have
demonstrated over and over again their ability to use progressive, creative
strategies to serve the taxpayers better,” Chief Dezelan said. “What
Captain Taylor has come up with here is tremendous. His is a great example of
a dedicated public servant who is doing all he can to give firefighters and
Indianapolis citizens the best service possible.”
Cryogenics involves the
use of liquid nitrogen to deeply freeze objects to temperatures of – 240°
to - 300°F. This cooling process is being used on brake rotors and drums of
IFD trucks, with the goal of reducing wear and tear and prolonging the life
these parts.
When metals are cooled
to temperatures approaching – 300° F, the grain structures become more
closely bonded creating a stronger, more durable material and all but
eliminating microscopic cracks that may occur in untreated metals. When
applied to brake rotors and drums, the cryogenic process can double or
possibly triple the life of the parts.
Replacement of these
parts on IFD trucks run close to $197 per rotor and per drum. Prior to the
use of cryogenic treatment, these parts would have to be replaced once
every six months according to Captain Taylor.
