In this example of an AHP-1200CP application a box surrounds the cold plate area. Materials are set directly upon the cold plate and the lid is closed. The material is cooled and temperature controlled without the large air cooling refrigerator.
A municipal waste plant had an emergency requirement for a water drop device (to condense moisture for analysis) to be installed in a smokestack. In this time critical application TECA responded with a custom designed variation of the AHP-150CP thermoelectric cold plate, to be mounted high up in the stack. Working with the customer TECA was able to design and deliver the product in less than two weeks, more than meeting the customer’s timetable.
Our customer calls the ICE-160 Electric Ice Trays a “dramatic improvement”. He uses several in his medical practice.
From our customer: “We use the ICE-160 during the quality-control and graft-storage portion of our minimally-invasive hair transplant procedures. While hair transplant grafts are outside of the body, they are fragile and susceptible to damage from dehydration and other factors as they are separated from their blood supply. During this delicate phase of the hair transplant, the harvested follicular unit micrografts are now in a special physiologic holding solution at 4 °C using the thermoelectric ICE-160 before and after being counted and sorted and while they are awaiting implantation. This is a dramatic improvement over the use of traditional graft coolers using frozen water which need to be swapped out often during a long NeoGraft FUE hair transplant procedure.
We are confident that this method of graft storage ensures maximum graft viability and helps us maintain exceptional results for our hair transplant patients. The solid metal surface is simple to clean and disinfect after each procedure. Thank you for this great addition to our practice!”
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.
An aerospace contractor was interested in a large cold plate for the testing of electronic components. We first offered them the AHP-1200CPV but they responded that the AHP-1200DCP was more the size they wanted. Could we change it to a single plate? Well, we couldn’t change the plate size but we could add an accessory plate which was larger. And we could build the unit with one controller including all of the standard options.
Now they are using the 12” x 18” custom accessory plate and a special AHP-1200DCP to test electronic amplifiers by ramping the temperature up and down between +10 °C to +70 °C. A custom solution at very nearly standard product price to fill a not so unusual need.
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.
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.
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.
Three AHP-1200CPV Cold Plates are running continuously and in tandem at 17 °C to monitor satellite equipment. The customer has added air deflectors of his own design. TECA offers standard air deflectors as well. The customer applies approximately 50 Watts of heat to the cold plate.
