POLYMER INDUSTRY
We have significant experience in the manufacturing of thermotropic polymers
by batch and continuous processes for film, fiber and bottle applications.
At N.H. ANDREAS CO., INC. we are experts on scrap recovery methods, extrusion, metering,
filtration of gels and filter cleaning processes.
|
We invented and own the S.A.C (Sintered Alloy Cleaners) Technology and have used same to provide filter cleaning services to:
Celanese.
Hoechst-Celanese,
DuPont, ICI Americas,
Ampex,
Poral/AfMetafram,
DSM,
LaCellophane
and others.

We set the world standard for hard hub sintered powder metal filters for the PET film industry working with Pechiney Ugine Kuhlmann ( FRANCE).
| NUCLEAR INDUSTRY |
|
We perfected first metal HEPA filters for nuclear aerosol filtration and
venting of nuclear power plants working with Bekaert Fiber Technologies(BELGIUM)
and Krantz-TKT(GERMANY). These filters are now deployed
on most European nuclear power plants and N.H. ANDREAS CO., INC. has
market rights for this technology on USA based nuclear power plants.
We have designed filter media for nuclear waste sample collection at
the Hanford site, facilities for nuclear scrap recovery processes and
the first solid phase isotope blending process to permit the reuse of
scrap uranium dioxide. Other experience includes operation of a sub-critical
R&D reactor and operation and engineering of nuclear waste water treatment
plants.

Engineered 316SS wicks for capillary transport of liquid sodium in the
Sterling Engine for SANDIA National Labs/Cummins.
Designed lowest cost media and automated production of filters for automotive
air bag applications.
We are currently working with clients to critique planned polymer filtration systems and to optimize performance of existing polymer filtration systems.
LIAISON ACTIVITIES
Our diverse experience working in basic R&D, Manufacturing, Process Engineering
and International Sales and Marketing in high technology industries makes
us uniquely qualified to function as liaison on joint projects. We know
how to persuade, negotiate and get the job done. Typical projects completed
include, basic R&D, Vipore Media/VHS PET Substrates, Technology Exchanges,
New Business Development and Contract Negotiations:
