Thermoelectric Air Conditioner Applications


One of our first customers to buy the AHP-6250 Model Solid-State Air Conditioner gives a wonderful example of the benefit of TECA’s newly introduced line of high-capacity thermoelectric air conditioners. Designed to cool larger enclosures than was previously practical with thermoelectric technology, the AHP-6250 is one of the largest models in this group. For example, the enclosure pictured here is about 8 x 6 x 3 feet. The customer is able to achieve large enclosure cooling with a single thermoelectric air conditioner. Thermoelectric cooling is reliable and maintenance free.

world's largest thermoelectric air conditioner

TECA’s new high-capacity line has some thoughtful design features, as seen pictured here on the installed AHP-6250. The cold side (internal to enclosure) has a low profile, which translates into less intrusion into the enclosure, giving the user more room for whatever the enclosure is meant to hold. The robust mounting flange, gasket and hardware and centrally located power input contribute to user-friendly installation. Finally, high air-flow fans and high fin-density heat sinks on the cold side maximize performance and minimize condensation. An integral condensate removal system absorbs condensation and transports it to the hot side, where it gets evaporated into the ambient.



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.”

Our customer manufactures various machinery and appliances for the beverage industry. One such system of theirs requires high performance and precision, achieved by using specially designed software and test & measurement equipment. TECA's thermoelectric air conditioner, the AHP-1200XE with built in temperature controller, is an important part of this system. The customer uses TECA's AHP-1200XE to reliably cool an enclosure housing a computer and touchscreen. The customer has depended on dozens of AHP-1200XE air conditioners over the years for use in their system.



Incubators used in the rearing of insects for research often experience thermal failures due to the acids inherent in the biology of the insects. The acidic environment that insects create can quickly corrode a standard, compressor-based cooling system- even if its copper coils are coated. High humidity adds to the problem because droplets of concentrated acid will collect on the cooling components. The solid-state nature of TECA’s thermoelectric air conditioners solves this problem offering reliability and virtually maintenance-free operation.

A published life science researcher from a local university contacted us because he experienced several failures from his compressor-based air conditioner units. He is raising flies in an incubator, and requires an accurate set point. The TECA Model AHP-1200 Thermoelectric Air Conditioner is the perfect solution. The air conditioner keeps the incubator to 18C as the customer requested. Using a remote, programmable temperature controller (TECA Model TC-3400) the customer is getting the accuracy he needs and the convenience he wanted from a remote controller.



A European manufacturer of special equipment for processing fruits and vegetables needed to cool sensitive electronics on their line of produce-processing machines, which sort products by color, size and weight.
TECA Model AHP1200XE solid state air conditioners were selected.
The equipment in use is washed down frequently, so the Model AHP1200XE is ideal because it is designed to meet NEMA4 and suitable for wash-down environments, while it also carries the CE Mark.



PLC cooler PLC cooling

A customer needed to cool a PLC enclosure housing critical electronics controls. They needed to keep the temperature of the enclosure in a safe range for the critical components. TECA's AHP-1200 series off the shelf air conditioner provided the cool capacity and ease of installation they needed.

This TECA model AHP-1200X was returned to TECA for evaluation, after over 120,000 hours of duty. It just did not seem to cool as much any more. As a matter of fact, it was originally put to work in 1992 cooling an electronic enclosure in a paper mill.

The customer was sure it needed to be replaced, but sent it back to us to see if anything could be salvaged. In our inspection we found that the hot side heat sink was fouled with 14 years of newsprint sludge. Once the goop was cleaned out and the fan was free to spin; the unit ran like a charm!

The maker of some of our favorite corn chips used TECA’s AHP-1200X for years in severe hose down environments.  They now had a similar requirement where they wanted to minimize any cleaning and were willing to entertain a liquid cooled LHP-1200XE solid state air conditioner.   The unit fit into the same area and footprint as its air cooled cousin and provided greater cooling capacity.  This customer added a valve on the water inlet to provide water flow only when cooling was required.  The units have been in service for years.



laser cooling

A physics laboratory at a large university required cooling for their laser. The enclosure did not have any room for an air conditioner to intrude. The flush mounted (mounts external to enclosure) TECA Model FHP-750 was the right solution.

TECA Air Conditioners are available as Flush Mount (external to enclosure), Through Mount (half in, half out) and Internal Mount (mounts internal to enclosure) to serve applications wherever space restraints may exist.



The alarm enclosure was for fire safety and switches. The transparent plastic enclosure was supposed to be accessible and secure while being cooled to desired temperatures under some of the harshest conditions, firefighting, where extremes of heat and harsh hose down conditions exist. The enclosure was selected already, load known, temperatures OK.  Everything was fine except the closest stock unit didn’t quite fit and it needed a few extra bells and whistles to provide the redundancy needed.  Taking the standard FHP-750XE air conditioner design, adding an extra circuit and modified sheet metal was all it took.
