History |

The
Tradition. Meeting
at MIT early in their
careers, Tark (formerly
North Co.) company founders
Joseph McCarthy and Ferdinand
Lustwerk, renowned mechanical
engineers with vast experience
in the heat transfer
and fluid flow fields,
have enjoyed a growing
reputation and wide-spread
recognition for their
design achievements in
x-ray tube cooling. Joe's
son, Jim McCarthy, Tark's
President, continues
the tradition, having
led the company into
new designs, processes,
and markets. |

Pumps. Tark's
first offerings were radial
magnetic drive (RMD) centrifugal
pumps for the medical CT
industry. Because higher
performance needs were
limited by the de-coupling
characteristic of RMD pumps,
Tark developed the hermetically
sealed direct drive pump
(HDD) in 1990. The key
HDD feature was its motor
actually running in the
oil it that was being pumped.
This allowed for a completely
welded-shut direct drive
pump, now the industry
standard. |

Cooling
Systems. Tark
realized early on that
the design of better
pumps was directly tied
to control of the entire
cooling system. Tark
began designing, manufacturing
and refurbishing complete
cooling systems in 1995
for medical CT then did
the same for airport
explosives detections
systems in 2002. Of course,
Tark is still the world
leader in x-ray tube
cooling pumps. |

New
Frontiers. Because
the technologies used
in cooling x-ray tubes
have widespread application,
Tark has recently begun
developing power density
cooling solutions, in
which more cooling is
needed in the same or
smaller spaces for many
applications, not only
x-ray tube cooling. Some
of these applications
include laser, transformers,
fuel cells, and high
voltage power supplies.
Tark's future is in becoming
the world leader for
such precision cooling
solutions. |
