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

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.

Where Are All the Cold Plates?

Cooling micro-organisms in a lab:

Recently, a prestigious U.S. university’s research lab contacted TECA. The team needed to cool a 340-well micro plate. Their vendors had many hot plates to offer, but no one seemed to offer a like product for cooling. The lab team was happy to discover TECA products online and the AHP-301CPV proved to be the right fit.

The lab’s 340-well plate is filled with a solution housing micro-organisms. To get the organisms to migrate to the bottom of the wells, the lab needed controlled cooling to 0degC. However, there is a limited temperature range in which the organisms do not degrade so precise control was paramount.

Freeze Tape Casting

Freeze Tape Casting Manufacturer:

A materials science company specializes in creating foams with specific porosity for use in electric vehicles, batteries, thermal interface materials and ceramic-metal interfaces. Utilizing a TECA thermoelectric cold plate as a component within the freeze tape caster ensures the manufacturing process remains environmentally friendly. Peltier cold plates use no freon, coolants, or chemicals of any kind. In this example, the customer has slightly modified a commercially-available, off-the-shelf (COTS) TECA cold plate to reach the desired -10C set point.
