Protecting Investments with Thermoelectric Cooling

?TECA coolers save automated sorting equipment from overheat failure:

TECA Model AHP-1202XEHC is out in the automation field by the hundreds, reliably cooling sorting equipment. Easily one of TECA’s most popular legacy products, the AHP-1202XEHC is a great design with a lot to offer. Maintaining NEMA-4/4X enclosures in high ambient conditions and in tough, industrial settings, the AHP-1202XEHC is yet an affordable solution. In the example shown here, our customer chose to buy from TECA for a long-term project, supporting recycling centers with automated sorting machinery. The sorting system is state of the art, using new technology which requires thermal management.

Wind Turbine:

The applications for AHP-1802XE’s are Vestas wind turbines, one located in Greece and one in the south of Japan.

“We are installing sensitive measurement equipment, and need to control the inside temperature of the measurement panel. One panel is in each of the rotors in the hub and the two others are in the nacelles (rotating and non rotating). We have just decided to make the two panels into one in the nacelle (where the panel in not rotating).”

Cooling Variable Frequency Drives

Steel Mill Enclosure Cooling:

A major steel company has multiple equipment enclosures, housing 4 variable frequency drives (VFD) each, to control their industrial cranes. The high temperature in the steel mill was causing excessive shutdowns. Compressor-based air conditioners could not survive the electrical enclosures’ harsh ambient environment on the overhead cranes. The only input power available was a widely varying 250 VDC, which complicated things. TECA successfully and affordably customized a flush-mounted (external to enclosure) thermoelectric air conditioner to meet the customer’s needs.

Ruggedized Military Application:

Sometimes it just takes a long time to get to the heart of a problem. AHP-1200X “quick quote” for two thermoelectric air conditioners came into our sales team. It was responded to and followed up. The application was reviewed, a quote was made and an order placed.

Only after did we learn that the hard requirements they were looking for were:

  1. Dual adjustable temperature control (heat and cool)
  2.  28 VDC operation and
  3. Military environment.

Fortunately the selections within TECA’s enclosure air conditioner family are large. The military Contractor borrowed a unit from TECA’s loaner stock and based on that success, placed an order. It was then that we found a problem.

It seems that the application was to cool some sensitive electronics out on a 200 meter DC input which caused droop in the input which in turn caused a ringing in the circuits. The new digital monitors being used were susceptible while the older tube monitors had no issue.

Working with the customer it was determined that by changing the controller to a ruggedized PWM controller all problems were solved.




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”.


Long-Term Communications Cooling

communications cooling 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.
