A major manufacturer of communications equipment was to go into production of special equipment enclosures, then encountered unforeseen problems with overheating electronics deep inside. The customer wanted air conditioning, but specified that no part of the air conditioner could protrude outside of their enclosure.

TECA designed a little air conditioner inside ducts for hot air exhaust. This way the air conditioner is actually housed entirely inside the enclosure and our customer continues production.

NUCLEAR PLANT

To cool equipment used for quality control inspection of pipes in nuclear energy plants. Evaluating the condition of pipes in nuclear power plants can be time consuming and costly. Automated and remote guided methods are available. Much of the electronics for the job must be rugged and durable, capable of handling many environmental conditions.

TECA designed, tested and built a system around standard portable cases. The unit shown is the prototype of the production unit, built into the top of a transportation case. Doing the design and prototype work of this nature often leads to happy customers and production jobs for TECA, as it did in this case!

AVIONICS MAINTENANCE

The task was to create a portable cooling system for diagnostic equipment to allow troubleshooting of avionics systems while still installed. Troubleshooting and diagnosing avionics problems is hard enough on the bench.

To save valuable time, technicians would rather get it done while the electronics are still in the aircraft. Also, under harsh environments, it is difficult to keep cutting edge electronics functioning the way they should. When it came to the type of portable cooling for the diagnostic equipment required for these jobs; a navy contractor came to TECA for the solution.

We helped design and build the solution shown in its prototype form around the portable enclosure. TECA completed the project on a tight schedule, which called for teamwork and attention to detail.

MILITARY TROOP TRANSPORT

It was 1994 and a military contractor came to TECA with a problem. The existing Freon based refrigerators used in troop transport galleys had a MTBF measured in months.

They had recognized the potential of thermoelectrics and contracted with a vendor to design and build refrigerators for them.  The problem came when the original vendor’s product failed to live up to its potential. TECA was approached and given only several months to design, build and test three prototype refrigerators for the first new galley.

Less than three months later with test data in his hands and three refrigerators in the back of his truck a TECA rep delivered the goods. Over twenty years later the military and it’s allies around the world are still flying these same refrigerators and ordering more.

COMPACT MILITARY AIR CONDITIONER

The contact to engineering read pretty much like this:

  • Wants A/C, 17.5 x 5.5 footprint, 150 W @ 0 Dt, He is in a hurry
  • Desert Application
  • Unit will require transport in, then it will sit for months, then it will go somewhere else
  • Single set point 35 °C control?
  • Size, can go 6″ on the outside

We suggested AHP-1200X, he said they didn’t choose because of no DC.  We could make it DC!  Nope, won’t fit, air flows are bad, 24 VDC, running off generator, NEMA 4X, Mil grade fans, 50 °C max, urgent need!

A little more than month later the order was placed and about 6 weeks after that a batch of custom air conditioners was being shipped.
