SURVEILLANCE

Video cameras needed to function in an environment beyond their rated temperature range.

One of our customers wanted to position cameras to observe a process from a location not safe for operators to go. The customer is a rubber manufacturer and the camera location was too hot for the cameras to work in. The customer had the cameras, but had no suitable enclosure, or cooling apparatus.

TECA adapted a tiny air conditioner based on Model AHP150XE to mount to a standard commercial enclosure. The package was completed by retrofitting the cameras with insulation and special cooling units. The design satisfied our customer’s needs to a “T”.

COMMUNICATIONS COOLING

Long-Term Communications Cooling

A common use for thermoelectric air conditioners is the cooling of electronics cabinets.

These photos show an outdoor communications cabinet being cooled with a system of TECA air conditioners that have been customized for the end user. The units photographed here are over 12 years old, a testament to the reliability of TECA’s thermoelectric air conditioners.

Also worth mentioning is the lack of maintenance that thermoelectric air conditioners require. With no moving parts except for the fans, no filters to change and no chemical coolants, TECA air conditioners are an ideal and environmentally friendly solution for remote areas.

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.
