Fire Safety Switches & Alarm Enclosure

TECA provides standard off the shelf as well as custom designs to meet the needs of the end user. Alarm enclosures can be exposed to some of the harshest conditions like the extremes of live-fire heat and hose-down. The alarm enclosure pictured here is for fire safety and switches. The transparent plastic enclosure is accessible and secure while being cooled to desired temperatures under harsh firefighting conditions. In this example TECA provided custom modifications to provide for redundancy and mounting requirements specified by the end user.

Contact teca@thermoelectric.com to inquire about custom designs for your needs. Our friendly sales team looks forward to hearing from you!

 

OUTDOORS KIOSK

An original equipment manufacturer designed a new outdoor information kiosk and required a small cooling solution, before they could start up manufacturing.

We consulted with the customer’s engineers and recommended TECA Model AHP-300XE, to provide the necessary cooling in a compact size. The AHP-300XE is an ideal choice for the application because it is a NEMA4 solid state air conditioner, designed for outdoor use.

WATER QUALITY MONITOR

The system pictured below is used to automatically collect and analyze water samples for water quality monitoring purposes. The system can be powered from the grid or from the attached PV system.

The TECA AHP-300 air conditioner is located within the enclosure and is used to keep critical internal components cool during the summer months.

MILITARY COMMUNICATIONS

A branch of the US military had a need for cooling a small enclosure containing a critical voice communication system. The shipboard system had to be resistant to salt water corrosion as well as pass stringent shock and vibration testing.

Modifications to TECAs AHP-300X solid air conditioner allowed the unit to meet specializing and air flow requirements and pass these tests. The challenge was to overcome the small available space both inside and outside the enclosure. The heat sinks were turned so that the heat rejection air flow and internal cold side air flow moved in different directions.

This unit is a prime example of how flexible Team TECA is when customer needs require customization of standard products.

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

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.

COMPACT MILITARY AIR CONDITIONER

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.
