COMMUNICATIONS:
Maintain the temperature of a battery bank in a Class 1 Division 2 explosion proof environment to power portable communications equipment. A special purpose vehicle manufacturer needed to maintain the temperature of a bank of batteries to maintain maximum performance. 
With our recommendation, the customer selected the TECA Model AHP1800XP, because it is the only NEMA4X air conditioner available off-the-shelf, which is also certified for C1D2 use. The power source was able to meet the requirement of operation in a Class 1 Division 2 explosion proof environment, to support portable communications systems at car racing venues.
HAZARDOUS ENVIRONMENT:
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.
CORROSIVE ENVIRONMENT:
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.
KIOSK:
Pictures below show a 4 year-old outdoor kiosk that is located in a zoo in the Sonoran Desert. The kiosk holds a computer and LCD screen, both generating heat, both mounted within an inch of each other. This active heat load coupled with the high ambient temperatures create a significant need for cooling. TECA's model AHP-1800XE Thermoelectric Air Conditioner has proven to be a reliable solution. Our customer raves “I had zero problems in past years, not even one tech. call. During the summer time here, when outside temperatures reach 95-110F, and surface of the kiosk gets as high as 125F, the LCD, computer and other components were running cooler than the components in our indoor kiosks.”
ROBOTICS:
An industrial plant uses robots in its juicing and bottling process. The robots continuously overheat and shut off. The environment is dirty and 240 VAC is the only available input voltage.
TECA’s AHP-1801X Air Conditioner offers dual voltage capability and a rugged hot side fan that can handle NEMA-4X and corrosive environments. The customer is able to use the built-in temperature controller to keep his robots at a cool 25C.
COOLING GLOVE BOXES:
A customer manufactures a range of glove box systems for atmosphere control applications in clinical and industrial environments. TECA air conditioners are a vital component on a variety of the glove box models that this customer produces. Standard and customized versions of TECA air conditioners from the AHP-1800-Series are used to control the glove box temperature to below ambient. Clinical applications primarily revolve around cell and bacterial studies within cancer research, bio-fuels studies, sleep apnea, anaerobic microbiology research and clinical applications etc. Industrial applications include product weighing or assembly with humidity and temperature maintenance.
MILITARY:
The 2.4 Meter Mobile SATCOM Tactical Terminal (MSTT) is a lightweight, stand alone, trailer-mounted tri-band SATCOM terminal available to support worldwide, quick deployment satellite communications through military and commercial satellites. 
It also uses a customized version of the solid state air conditioner AHP-1801X. It was designed and qualified for worldwide operation in tactical military environments.
ROOFTOP EQUIPMENT ENCLOSURE:
As of this writing, the system has been operating trouble free for over 90,000 hours.
Back in March of 2001 TECA Corporation engineering team set up a test to evaluate functionality and life of it’s then new XEseries of solid state thermoelectric air conditioners under real life out door environment conditions.
Model AHP-1800XEHC Heat/Cool air conditioner was chosen as a representative model.
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)."
TRUCK PROCESSING TERMINAL:
 To keep sensitive electronics used in truck processing terminals in safe and operable temperature range a system integrator company uses TECA AHP-1800XEHC peltier based cooling and heating system. This system minimizes truck processing time, and maximizes user productivity.
LARGE LCD SCREENS:
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.

overhead cranes. On top of all that the only power they had was a widely varying 250 VDC. Which we found out later had some very nasty spikes which caused everyone a few headaches. But the headaches were cured and the customized 
TECA Model 
A “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.
Modifications to TECAs 
Keeping sensitive electronic instruments and equipments at optimum operating temperature range often is one of the most important issues in designing an enclosure system housing the instruments. A manufacturer of first response vehicles was able to maintain it’s sensitive electronics in safe operating temperature range using a custom peltier cooling system designed by TECA Corporation. 
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.
