New high performance enclosure air conditioners introduced by TECA

CHICAGO, Ill., 14 June 2012. TECA Corp., a designer of cooling devices based in Chicago, Ill., has introduced two new thermoelectric air conditioner models with a heat exchanger mode, the AHP-2250 and the AHP-3250. These are the largest air conditioners TECA manufactures. The AHP-2250 offers 605 watts cooling capacity. The AHP-3250 offers 765 watts cooling capacity. Cooling capacity ratings are measured at a 0 degrees F temperature differential. Heat/Cool versions of the AHP-2250 and AHP-3250 are available and heat capacity is 1100 watts and 1600 watts respectively. These air conditioners are designed to cool high-heat electronics such as military embedded systems.

The unique heat exchanger feature on these devices is designed to save energy. The heat exchanger mode switches on as the enclosure temperature rises through 25C and the need for cooling begins, providing passive cooling without using much energy. This can also help keep the enclosure below the active cooling set point for a longer period of time, limiting the time the thermoelectric modules need to be actively cooling. The AHP-3250 uses 83% less energy in the heat exchanger mode than it does in the active cooling mode at 18 watts per degree Celsius cooling.

TECA's thermoelectric air conditioners provide mission critical enclosure cooling and protection. TECA air conditioners are suitable for indoor or outdoor, harsh environments in the air, on land or at sea. In addition to the ability to perform in high ambient temperatures, TECA air conditioners use industrial grade or military grade sealed fans, depending on the configuration required. Active cooling and heating is achieved with the use of robust thermoelectric modules. Long service life within a virtually maintenance-free system make TECA air conditioners the right choice for remote installations.

A temperature controller is built into the AHP-2250 and AHP-3250 models. All configurations include either a cool only TC-4F or heat/cool TC-7F integral temperature controller. The heat exchanger function is included in all configurations as well. The heat exchanger function will switch on (passive cooling) when the enclosure reaches 25C. Active cooling switches on when the enclosure reaches 35C. On heat/cool configurations, the TC-7F will switch on the heating function when the enclosure temperature drops to 10C. All heat/cool models heat via reverse polarity of the thermoelectric modules.
