Thermoelectric innovations by TECA

TECA pioneered thermoelectric technology and was the first to market solid state air conditioners for electronic enclosures. Applications we serve include harsh environments such as NEMA 4X and CID1 explosion proof for military and industry. Our products have even been used in demanding applications such as the NASA Space Shuttle (6 missions) and nuclear power plants. We don’t just make air conditioners. We do it all! Including air-cooled, liquid-cooled, AC and DC input re-circulating liquid chillers, cold plates for laboratory and industry, plus all the ancillaries and accessories like temperature controls and power supplies for DC.

Here is an abbreviated history of our development from 1960 to the present:

2019: Offering a new option for histology laboratories (or anywhere a quiet, low profile cold plate is needed) TECA’s newest Thermoelectric Cold Plate is Model ERGO-900. At just over 2.5 inches high it is scaled for use at individual microtome stations. Also useful for repetitive tasks and in-line processes.

2018: A great example of TECA’s customer service and product innovation, the 100-140 BTU/HR air conditioners are now available with a space-saving, integral temperature controller at a lower price. Ideal for cooling controls in rail, intermodal, security, and other small enclosure applications.

2017: Our customers demanded the new AHP-5400CPV, TECA’s newest and now largest cold plate for direct-contact electronics cooling, quality testing, and other processes in industrial, manufacturing, and research applications. 5.5 sq.ft. hot or cold work surface!2017: TECA launches its Quarterly eNewsletter to share new product information and timely thoughts to our customers and opt-in prospects.

2016: Supporting our customers in the fields of crane equipment, water treatment, and other industrial sites, TECA offers new control cooling for 3-Phase power systems.

2016: Helping laboratories obtain reproducible results by getting rid of water-borne contaminants, TECA’s Magnetic Stirring Cold Plats & Bath utilizes lab beads in place of water or ice. Environmentally friendly, lab beads are reuseable, washable, help organize small samples, and are always ready-to-go, saving valuable time.

2015: Allowing customers to save external space when needed, TECA designs a line of Internal-Mount thermoelectric panel coolers.

2014: Disrupting the industry before that was a thing, TECA introduces the AHP-6263 thermoelectric air conditioner. With a half ton of cooling capacity, it is the largest thermoelectric enclosure cooler available anywhere. Why does this matter? Thermoelectric cooling technology is introduced into new applications, cooling larger cabinets and enclosures than ever before.

2012-2014: A new collection of high performance, high efficiency thermoelectric air conditioners for enclosure cooling are the first-to-market with cooling performance above 2,500 BTU/HR as well as the best in energy efficiency.

2011: Several agency approvals are obtained for TECA’s thermoelectric coolers, to UL and CSA standards. Click for ETL info.

2011: Highly efficient thermoelectric air conditioners are introduced. TECA models designated as Green Zone™ have a coefficient of performance (COP) rating of X or better.

2011: The first energy-saving temperature controller in a thermoelectric air conditioner, TECA’s unique Eco-Mode™ Control Feature reduces operating costs. It takes advantage of passive cooling in low-demand times, drawing significantly less power. Click for more details.

2010: Cooling as low as 90degC below ambient temperature, Thermoelectric Cascaded Cold Plates are introduced for direct contact cooling applications.


2000-2005: Four new thermoelectric recirculating liquid chiller product lines are developed and introduced. A new line of laboratory cold/hot plates are created, with versatile features for use in laboratory research and product development. click for cold plates; click for liquid chillers

2005: TECA Model AHP-301CPV thermoelectric Cold/Hot Plate is used in a published research study. TECA Cold/Hot Plates and Liquid Chillers continue to be routinely cited in peer reviewed journals. click for article citations

2005: RLC-1400 Rack Mount Liquid Chiller is introduced for cooling and heating 19? rack panels.

2006-2009: TECA introduces an extensive product line of versatile Peltier cooling and heating products specifically designed for laboratory and research. New features such as universal input voltage, remote temperature sensing, data logging software, fan speed control and new accessories help end users adapt TECA’s cold/hot plates and liquid chillers to their individual needs. click for details

2007: TECA designs, markets and sells the first thermoelectric stirring cold plate. The AHP-800MSP Magnetic Stirring Cold Plate Model cools, heats and stirs a liquid load. The AHP-800MSP remains a popular solution for pharmaceutical, petrochemical and chemistry applications.

2008: TECA Model AHP-1200DCP Dual Cold Plate, the world’s largest Peltier cold plate / hot plate with dual, independently controlled, temperature zones is introduced. It is used and cited in published, peer reviewed thermal preference studies and pain studies (thermal nociception research). click to view data sheet


1992: TECA introduces the AHP-1800X. Building on the success of the earlier AHP-1200X, it is an even larger thermoelectric air conditioner suitable for electronics protection and cooling NEMA-4X/Harsh Environment enclosures. This allows for reliable thermoelectric thermal management in larger cabinets than ever before. click to view products

1993-1995: TECA designs and brings to market several new Peltier style liquid chillers, temperature controllers and panel coolers. Expanding TECA’s product line gives more flexibility to the end user and brings thermoelectric cooling technology to new customers.

1995: TECA offers flush-mounted enclosure coolers. The FHP-Series thermoelectric air conditioners do not intrude into enclosures. These panel coolers allow for more space inside the enclosure for the end user’s components. click to view products
