Here’s a step by step of an AHP-1200CAS/CCP-22 Cascade system our engineers were playing with. They took a purple EasySep magnetic nano particle vessel, set it on the cascade, insulated it and then cycled it up and down for kicks. The curve shows the results. Faster times can be achieved by thinning out the plates and building the cascade into the AHP-1200CAS rather than having it as an option.
Talk to TECA engineers if your interested.
A research organization had a problem with overheating of their equipment in a chemical-vapor deposition reactor TECA’s AHP-301CPV Cold Plate cooled the equipment and improved the performance of the customer’s system.
The customer was able to avoid system failures, which allowed the completion of a research project.
A technological university in Asia chose TECA’ s thermoelectric cooling Model AHP-800MSP Magnetic Stirring Cold/Hot Plate to anodize aluminum. The researcher’s process required a temperature of 10 °C.
The AHP-800MSP‘s universal input voltage feature (100-240 VAC) allows it to be used anywhere, making it a perfect, off the shelf choice for our customer in Asia. He wrote to us: “It is quite good. Also the manual is quite clear and quite user-friendly. Thank you.”
Unique to this product is the adjustable nature of many of its features: stir-bar speed, fan speed (for noise reduction), temperature sensing (internal or external) and more.
The AHP-800MSP can even accept beakers of various size by adding optional sleeves. The solid-state thermoelectric construction is low-maintenance. There are no filters to change and no moving parts except for the fans. Our products use robust thermoelectric modules and boast a long service life.
A company specializing in hydrogen fuel cell technology required fast cooling of a fixture. The fixture is bonding multiple thin materials and can be heated up to 100 °C. The fixture needed to be cooled to the point where it could be handled by technicians—within a 5 minute time frame. Using two AHP-1200CP Cold Plates from TECA, the customer has created a system where a heat sink is cooled on one AHP-1200CP Cold Plate while a hot fixture is sandwiched between a second AHP-1200CP Cold Plate and a pre-cooled heat sink.
The customer reports being very happy with the TECA Cold Plates—the system is cooling in about 4 minutes! The AHP-1200CP Cold Plate is an economical, easy to use product when maximum cooling is required, without a temperature controller. 120 VAC, 240 VAC and 24 VDC versions are available.
Customer plans to use the TEC unit to regulate the temperature of some electronics in an outdoor enclosure. The electronics will be mounted to a cold plate where they can be cooled by direct contact with the TEC. The walls of the enclosure will be insulated to reduce thermal losses to the outside world. The hot side of the TEC will be in a separate, ventilated part of the enclosure to carry away waste heat. Customer will provide longitudinal air flow along the heat sink, so the built-in fan will not be necessary.
Originally considered using a solid-state air conditioner to cool the entire enclosure, but now prefers the direct-contact method for lower cooling requirements and smaller size. The active load that needs to be cooled is about 50 W. It will consist of a number of RF components (amps, sources, etc) mounted to a common cold plate. Several passive components will also be mounted to the plate. The whole temperature-controlled assembly will be insulated by an inch or so of foam or something similar. The ambient temperature range is roughly 0 to 100 °F at the extremes.
Here’s another example of an AHP-1200CP thermoelectric cooler plate (Peltier cooler plate) used in a manufacturing station. The adjustable feet provide vertical flexibility in lining up the cold plate with the workstation. Parts slide easily from the hot plate to the work surface to the cold plate.
A company specializing in 3-D designs for museums, theme parks, and other attractions needed to build an “icy throne” for a museum exhibit and keep it dry at the same time.
Using four TECA AHP-1200CP Peltier cold plates (thermoelectric cold plates), one was placed in the seat, back, and in each arm rest of the throne. Raw aluminum was then screwed onto the plates, and the throne surfaces reached close to -20 °C! Visitors to the museum can sit on the throne to feel the chill. The “ice” in the picture is not real. It is a “hard coat” of scenic ice. The throne manufacturers did not want museum visitors to get wet from real ice; their goal was to create a throne.
Department of histology in a major hospital needed a peltier cold plate to freeze tissue samples for examination. The Histology Division of the Department of Pathology places tissue samples from biopsies into a small block and fills it with wax. Several of these samples are then placed on one of the AHP-1200CP thermoelectric cold plates (Peltier cold plates) to “pull the heat” out of the wax so it gets really hard.
The near-frozen samples are then shaved down to the desired section (slice) using a Microtome (in picture). The thin sections are then placed in the water bath to warm up the remaining wax in order to remove it and then place the section on a slide for examination.
A customer heard about TECA’s Thermoelectric Cold Plates through word-of-mouth and placed an order within a week. The AHP-301CP Cold Plate is used in the customer’s 3D printing process. Parts are printed on an aluminum plate which is then set on the AHP-301CP Cold Plate.
As the AHP-301CP Cold Plate cools the aluminum plate, the 3D prints just pop right off of the aluminum plate. The customer is pleased with the performance, ease of use and low purchase price of this basic model.
The AHP-301CP series is replaced by the newer AHP-401CP series.
The customer was looking for a cooling solution for LED chips. With a heat load as high as 45 watts at times, the customer needed to cool the chips quickly. The customer was able to utilize TECA’s Loaner Program and test the AHP-301CP cold plate before purchasing.
Satisfied with the AHP-301CP performance, the customer has since purchased several more and sold them as a part of his total system to his clients.
The AHP-301CP series is replaced by the newer and updated AHP-401CP series.
