A custom design solution based on a standard thermoelectric air conditioner AHP-1801X was developed to meet European hazardous environment specification (ATEX) for a customer that was in need of such a system in a very short time.
The AHP-1802XPHC-2 met the customers need in an application where other similar products could not function due to extreme corrosive environment.
The TECA design team in a short notice was able to provide a solution based on a standard AHP-1800X thermoelectric air conditioner.
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).”
Intermodal systems are increasingly upgrading to automate their processes. Where there is automation, there is a need for control cooling. TECA supports automation by protecting crucial electronics in control cabinets. This minimizes process time and maximizes productivity.
In this example, heat-sensitive electronics are installed in truck processing terminals. TECA Model AHP-1800XEHC offers heat and cool modes and keeps the equipment within safe and operable temperatures.

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.
Specializing primarily in the food and beverage processing industries, one of our longtime customers uses TECA air conditioners in several applications. These include cooling or heating LCD screens, desktop computers, thin clients, and KVM kiosks. The locations of these applications are indoors, outdoors, in cold rooms and baking areas.
TECA’s comprehensive line of air conditioners fit the bills. We offer each model in different configurations according to the customer’s need regarding input voltage, mounting and application environment.
A customer required a constant temperature to keep his detectors working in a coal analysis application. Due to experiencing failures with a competitor’s air conditioner, the customer reached out to TECA.
The solution was TECA’s FHP-1501XEHC Model, a versatile thermoelectric air conditioner offering heating and cooling as well as dual voltage: 120 or 240 VAC input. Built with an industrial grade sealed fan and components, the FHP-1501XEHC is suitable for NEMA-4 enclosures.
TECA’s Model AHP-1202XEHC Thermoelectric Air Conditioner provides accurate heating and cooling for the customer’s analysis machine. The environment is harsh: it is in a cement plant.
The customer’s product quickly analyzes composition of raw materials, allowing for increased productivity. TECA’s AHP-1202XEHC provides reliable thermal management within a harsh environment. The AHP-1202XEHC has an industrial grade sealed fan and sealed hot side components, allowing for frequent wash down (NEMA-4).
The solid-state construction is the perfect low-maintenance solution for hard-to-access areas. There are no filters to change and no moving parts except for the fans.
TECA air conditioners use robust thermoelectric modules and boast a long service life.
Site monitor and security equipment for oil fields and transfer stations needed more security. A portable enclosure housing cameras, WI-FI access, antennas and a Mac Mini computer inside leveraging the Mac platform to provide virtually instant access, hi speed, via “Wild Blue”. The system will be like a watchdog that they can strap on wherever they need the monitoring.
With a slight modification an AHP-1200XE thermoelectric cooler provided the best solution while keeping the NEMA-4 rating of the enclosure.
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:
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.
