Power Efficiency in a Marine Environment

Control Cabinet Cooling:

An engineer, tasked with upgrading a dozen control cabinets on sea-faring vessels, contacted TECA for advice. Although the cooling need was not large, there were many other challenges to the project. TECA’s customer needed a truly robust cooler; something that could be exposed to vibrations, high ambient temperatures of 60degC, and salt spray from the ocean. Furthermore, power efficiency was a must. TECA’s thermoelectric coolers have the highest power efficiency ratings in the industry. TECA Model AHP-590XMHC was able to meet every single requirement.

Control Cabinet Cooling TECA Model AHP-590XMHCLike all TECA “XM” units, the AHP-590XMHC has military-grade fans on both the internal and external sides. Providing protection against salt spray (Mil-Std 810 Corrosion), TECA’s “XM” units also have full protection from exposure to shock and vibration. TECA’s unique ECO-Mode temperature controller feature limits the amount of time the cooler needs to be actively cooling. Utilizing passive cooling in lower demand times draws 95% less current. During high demand times, the active cooling function of the AHP-590XMHC draws 32% less current than its closest competitor on the market.

TECA Gives Back

Donation for Outdoor Kiosk: Thermal Management

Recently, TECA was honored to have the opportunity to help non-profit with a cooling project. TECA Model AHP-1800XE fills a need for cooling the inside of a free-standing kiosk, thus protecting its electronic components. The kiosk is located in the Veterans Memorial Park in Pensacola, FL where the heat index can reach above 100F. The AHP-1800XE air conditioner has been installed and the customer reports it is functional, easy to install, and quiet.

Cooling RF Device with Liquid Chiller:

under the radar

TECA Corp. manufactures an extensive line of thermoelectric, recirculating liquid chillers. Typically used in laboratories, TECA’s chiller Model RLC-1800 recently adventured out into a more unique application. In this application, TECA was able to help a contractor working for the USAF to reduce cost. The contractor required a replacement chiller with the same form, fit, and function as their original (non-TECA) equipment. The TECA engineering team found a way to modify the RLC-1800 to satisfy the customer’s requirements, while keeping the expense to a minimum. The cooling capacity of the RLC-1800 is our largest in a mountable chiller.

Food Manufacturing Cold Plate:

Tight Temperature Control
Food Manufacturing Cold Plate

TECA’s smallest Laboratory Air Cooled Cold/Hot Plate, Model AHP-301CPV, offers precise temperature control, protecting food samples in a sensitive application. In this example, our customer has placed food samples into a simple aluminum block insulated with Styrofoam. The AHP-301CPV Cold/Hot plate can be used to control the temperature to a tenth of a degree. This thermal management solution provides a small footprint. More importantly, the samples can be reliably cooled or heated to a variety of temperatures per the end user’s requirements. Our customer reports the rapid transition between temperatures is beneficial.

 

The AHP-301CPV, part of TECA’s extensive “CPV” product line is a UL/CSA, CE-Marked product with a decade of experience serving in laboratories worldwide. The built-in temperature controller and communications software allow for versatility in use. Modifications and additional accessories are available to suit the end user’s needs. Please explore the different sizes and types of cold/hot plates TECA offers here. If we can be of assistance, please do not hesitate to contact us. We would love to hear from you.  Phone 773.342.4900

Bill Pay Terminals, Kiosks

Kiosk cooling:

TECA Model AHP-451XE Peltier coolers are protecting over a dozen customized bill-pay kiosks. This example illustrates the power of TECA’s smaller air conditioner models. With just over a 100 Watts of cooling power, the AHP-451XE is meeting the thermal requirements of this fairly large (over 4’ tall) kiosk. Housing heat sensitive equipment including computing core, printer, imager, and a 15” LCD touchscreen, this kiosk is exposed to high ambient temperatures as well.

Payload Testbed

Space Satellite Components

Over a dozen TECA Cold/Hot Plates are operating in a cleanroom environment. As part of a significant research undertaking, the European Space Agency’s (ESA) microwave lab has assembled the navigation payload components of a Galileo satellite on a test bench. Components can be separately temperature controlled, using TECA Cold/Hot Plates. “This is important because part of the facility’s job is to recreate anomalies occurring aboard the satellites, which includes reproducing their environment” says ESA microwave engineer César Miquel España.

Another Day, Another “A”

Thermoelectric Cold/Hot Plate Replaces Liquid Nitrogen:

TECA’s cold/hot plates utilize thermoelectric cooling, a solid-state method of heat transfer. Also called the Peltier Effect, this technology is valued for its reliability and lack of maintenance needs. For over a decade, TECA cold/hot plates have been cited in peer-reviewed, published academic research papers. Pictured here is our youngest known researcher, a 7th grade student who designed a physics experiment for her school science fair. TECA could not pass up the opportunity to support a budding scientist and lent our Model AHP-301CPV, free of charge.

thermoelectric cold plate

Lisa, a 7th grader, used the AHP-301CPV in her science fair project, Electric Ice. Following the methods from a paper published in the journal Science, she obtained pyroelectric crystals, which develop an electric field in response to a temperature change. When the pyroelectric crystals are cooled in a controlled manner, their electric field affects the freezing point of the moisture in the air that condenses on them.

Unlike the scientists in the Science paper, Lisa did not have access to large amounts of liquid nitrogen to provide the cooling. Enter TECA Model AHP-301CPV Cold/Hot Plate. The pyroelectric crystals, housed in copper cups, were placed on the cold plate surface. Using the AHP-301CPV’s integral temperature controller and included communications software, Lisa programmed the cooling to ramp down by 2°C per minute, from room temperature to -20°C. A video camera recorded the condensation of the ambient moisture and its subsequent freezing. By comparing the time base of the video with the data captured by the AHP-301CPV’s communications software, Lisa was able to measure the freezing temperature for 3 separate configurations: within a positive electric field, a negative field, and no electric field.

Controlled Temperature Cycling in a Research Lab

Direct contact cooling 65°C below ambient:

controlled temperature cyclingA large state university in the U.S. has been using a collection of several TECA Model AHP-1200CAS Cascaded Cold/Hot Plates for years, to perform various research on the characteristics of cement paste samples.

In a cascaded system, the thermoelectric element acts as a heat sink for the element above it. Therefore, the more “stages” there are, the colder the top-most stage becomes. The research team which provided this photo successfully ran temperature profiles such as: from -20° to +24°C, and +23° down to -40°. This consistent accuracy and reliability of TECA Cold/Hot Plate products are a smart addition to any lab needing plug-and-play benchtop cooling or heating.

All Laboratory-Style TECA Cold/Hot Plates include an integral temperature controller and tecaLOG communications software. Versatile accessories are available such as cutting surfaces for grossing, barriers for lab animals, and more. The possibilities are endless. Please reach out to us for help selecting the right TECA solution for your lab. Ph 773.342.4900.
