HAIR REPLACEMENT PROCEDURE

 Hair Transplant Procedure, Follicular Unit Transplant/Extraction (FUT/FUE):

hair transplant procedure

A group of physicians pioneered a hair replacement procedure using TECA’s AHP-1200CPV Cold/Hot Plate. The AHP-1200CPV is a Peltier cold plate. In the photo provided by TECA’s customer, the cold plate keeps hair transplant grafts cool in a solution during the patient’s procedure. The convenience of the AHP-1200CPV cold plate’s built-in temperature controller allows the technician to easily program it to maintain the desired set point.

The AHP-1200CPV is capable of reaching temperatures as low as -15 °C. In the photos here, the set point is programmed to 5 °C. The AHP-1200CPV has an integral universal power supply, so it can be used with any input voltage range from 100 to 240 VAC.

 

ELECTRONIC TEST STATION

This is how the TECA Model AHP-1800CPV got its start. An aerospace contractor was interested in a large cold plate for the testing of electronic components. At the time our largest standard cold plate was the AHP-1200CPV. The client requested a larger plate. We added an accessory plate which was 12×18 inches (pictured).

This solution worked well, and we followed it by designing three new products:
AHP-1800CPV, AHP-2700CPV, and the AHP-5400CPV. These products have larger plates, ideal for working with multiple components or larger sized DUTs.

At TECA, we listen to our customers’ needs and push the limits of our designs- this is how we innovate! https://www.thermoelectric.com/about-teca/

MEASURING PLANT METABOLISM

A university-based agriculture research laboratory in Spain is measuring plant metabolism under various conditions. TECA Corporation’s high-capacity version of the AHP-1200CPV (please refer to part number 9-35KB-1-0A0 on our product specification sheet) is used to cool the plant to 22 °C. Precise temperature control is important in this application as the plant’s roots must not get too cold.

There is a significant heat load to deal with as well: the plant is being illuminated with LED lights. Finally, thermal contact is an issue. The plant is inside a glass container, which is inside an aluminum block, which is placed on the AHP-1200CPV Cold Plate surface. Working closely with TECA engineers, the customer was successfully able to integrate the AHP-1200CPV Cold Plate into this unique experiment design and his sensitive thermal management needs were met.

The customer shared with us: “Your suggestion to add water between the glass and the aluminum block is a good one. It does lower the temperature inside, probably by increasing the thermal contact. The fit between the block and the glass is pretty tight. The glass was made first and then the block was drilled out using the glass as a reference. Still, even a tiny space basically ruins the heat transfer, so adding the water seems to fix that. Thanks for your help and suggestions, they were quite useful.”

A materials scientist at a state university used TECA’s AHP-1200CPV to conduct published research. The researchers built a thermal fatigue chamber using the AHP-1200CPV.

A 2mm-thick specimen was sandwiched between two laboratory-built hot plates. The hot temperatures were as high as 400 °C.  The AHP-1200CPV cold plate cooled the researchers’ load to 30 °C. Our customer reports that he was able to maintain the 30 °C temperature within +/- 2 °C.

TEMPERATURE CYCLE

A university research laboratory uses TECA’s AHP-1200CPV Cascade system to perform nucleation studies. The AHP-1200CPV Thermoelectric Cold/Hot Plate paired with a CCP-31 Cascade attachment creates a low-temperature cooling system. The customer is able to control the temperature of an aluminum dish, rapidly cycling between +20 °C to -45 °C.

The Plexiglas box on top is to contain a dry nitrogen flow, which prevents condensation and frost from forming on the experiment stage.

COOLING CHICAGO

Have you ever wondered what the Chicago Skyline looks like after a nasty Noreater blows in off the lake? The creative machinists at Metal Concepts in Chicago constructed this city skyline to highlight the cooling capacity of our AHP-1200CPV product.

The V stands for Versatile and given it’s used in so many industries I guess it’s not hard to see it cooling the city. Interested in cooling a city of your own? Send us some pictures or sketches and we’ll see what the artists at Metal Concepts can do for you.

A global leader in developing and manufacturing cochlear implant systems uses the AHP-1200CPV to cool down silicone molds after the curing process so the operators can safely handle the mold. So far the cold plate has been performing perfectly.

Customer uses TECA AHP-1200CPV cold plate for a very accurate temperature control of a transmitter. The temperature of the unit under test is always the same, no matter what power it dissipates.

The thermal control loop works great and there is never a problem going cold or hot or switching power on or off.
