Shown here is a prototype cooling solution for an outdoor payment device. Located in a desert environment, overheating is a big issue in the summer months. TECA’s AHP-270XE serves the requirement nicely. The energy saving “ECO mode” control feature means that passive cooling is utilized as temperatures rise. Only in the highest demand time does the active cooling component turn on. The AHP-270XE’s small size is ideal, leaving enough room inside the enclosure for other components. Thermoelectric technology means a reliable, low maintenance cooling solution with virtually no maintenance costs. The customer can expect years of trouble-free, reliable cooling. The customer reports, “Our cooling solution has been very successful so far this summer.”

Copper Heat Sink : Modification to a standard product

Thermoelectric panel cooler with copper cold side sink

A chemical analysis service provider used TECA’s thermoelectric air conditioner as part of a larger system. The end user required copper heat sinks instead of aluminum heat sinks. TECA provided this modification to a standard product, the AHP-270XE. This is one example of modifications TECA can accommodate, including black anodizing of aluminum parts, using 316 stainless steel instead of 304, and much more.

Cooling Mobile Radar Controls:

TECA Model AHP-1802-Series air conditioners are mounted on long-range and precision radar equipment. The long service life of thermoelectric cooling products and the low maintenance requirements contribute to the radar system’s low cost of ownership. The life expectancy of a thermoelectric device is exceptionally high due to its solid-state construction. Service life typically exceeds five years under normal conditions. For individual modules, Mean time between failure of 200,000 to 300,000 hours at room temperature and 100,000 hours at elevated ambient temperatures of 80degC have been calculated. The reduced need for maintenance and replacement parts are a significant part of the value added to using thermoelectric technology.  Contact TECA today to discuss your cooling requirements. 773-342-4900

Temperature Preference Testing

Temperature Preference Testing with TECA Thermal Gradient system:

A university research laboratory is pleased with TECA’s Thermal Gradient Bar. It is being used with two TECA Model AHP-1200CPV Cold/Hot Plates to create a gradient.

Model AHP-1200CPV Cold/Hot Plates to create a gradient

 

The user writes:
We are using the TECA cold plates to create a thermal gradient from 10 to 50 degrees C. We have 6 aluminum tracks running from the hot plate to the cold plate. We place ground beetles (family Carabidae) on the center of the gradient (one in each track), cover them to reduce light interference, and allow them to acclimate to and explore the track for 15 minutes. We then do a series of 8 checks every 5 minutes and record their location on the track at each check. We initially used 10 thermocouples along the track to model the temperature at each location and can now infer the temperature the beetle was resting at during each check based on its location. Ultimately, we are using all these measurements to estimate the preferred temperature of each ground beetle species. So far, we have experimented with about 10 species, and hope to test more species next year.
