A research and development team in Europe uses the TECA Model AHP-1200CPV Cold Plate with a TECA Model TC-1 Tube Chiller attached.
Their process is proprietary but involves optical material and measurements. The TC-1 Tube Chiller is designed to heat or cool fluid without introducing contaminants to the fluid.
The fluid flows through the flexible tubing (various tubing diameters are possible) within the plate surface.
The customer makes fiber optics and related components and subsystems, they use an AHP-1200CPV cold plate for testing components.
They are using it to run temperature test on them, they set the temperature, and it goes to temperature and sits there, heating or cooling.
“It works well”. Before they were cobbling together home brew solutions with a heater here, a circuit and a fan there but it’s nice to have a system that does it all.
An oil refinery runs tests on asphalt samples at different temperatures.
TECA Model AHP-301CPV Cold Plate is currently being used during the course of the customer’s testing.
The customer says, “We have used this unit at different temperatures, and it has performed well. Thank you for your follow-up on the performance of this device.”
The customer makes high performance crystal oscillators and atomic clocks for satellites and laboratories and they needed something for temperature control and stabilization.
They found TECA and the AHP-301CPV, tried one and say it is “working fantastic”. Well enough to order more for production, quality and engineering tests. They use them to maintain a stable temperature of the oscillator which in turn provides a stable frequency.
A product design engineer at a medical device company needed a way to cool wax blocks holding film. The wax is printed directly onto the customer’s aluminum tray. Before discovering TECA products, the customer was placing the aluminum tray in a refrigerator and mechanically removing the wax by scraping it off with a metal blade.
TECA’s AHP-1200CP Cold Plate is a better solution. The customer is happy to have found an affordable cold plate to dedicate to his cooling task.
Please view the video provided by our customer to see how quickly and easily the wax is now removed (no more scraping!).
Here’s an application that our engineering crew would love to put into greater use if they could figure out where and how. A specialty gas company called. They wanted to transfer toxic and corrosive liquids from big to small containers for lab use. The process had been taking several minutes with too much wasted product.
They knew because of the conditions a natural head pressure in the big container that they could use a cold plate to cool at the receiving vessel (Ø 1.5″ x 12″ bottle) to create a driving force which moves the fluid.
We didn’t go into the physics of this, we trusted what the customer said and worked with them. When they tried an AHP-1200CP it was fantastic. It turned 4 minutes and a lot of waste into no waste and 40 seconds.
Customer needed to test low-temperature performance of inertial measuring devices. In this application of low temperature thermoelectric cooling; the user is testing inertial measurement devices over a temperature range.
The devices as well as the TECA cascaded cooling assembly are subjected to various rotational and acceleration stimuli while device temperature is controlled. The custom thermoelectric cold plate cascaded (Peltier cascade) was built up from a standard Model AHP-301CP cold plate.
The finished test fixture was able to function with a maximum rotation rate of 1700° per second and 50 g acceleration. The rotation is evident in the photo. By using a standard product as the basis for the cooling system, higher costs associated with a custom solution were avoided.
Some engineers at Lucent wanted to cool devices inside a vacuum chamber and they didn’t want to reinvent the wheel. TECA’s been making devices like that for decades. They had a load of 10 to 20 watts generated and wanted -40 °C with about 15 °C to 20 °C water available.
A Custom LHP-800CP / LHP-300CP cascade, controller and power supply were supplied for a reasonable cost in a reasonable time frame.
A research lab in Europe needed to stabilize the temperature of an acid solution within +-0.5 °C. TECA’s AHP-301CPV Cold/Hot Plate was the ideal solution due to its small footprint, versatile features and programmable temperature controller. The customer offered the following comments:
TECA’s cold/hot plates are not specifically designed for clean room use however the customer determined this product would be suitable given the restrictions in this particular clean room.
A university research team utilized TECA’s AHP-1200C31 Cascaded Cold Plate to build a calorimeter for a research paper that was recently published. The researchers aimed to determine the thermal properties of their specimen as part of a study on cement and concrete durability.
Originally the customer used only the AHP-1200CAS base cold plate and was able to reach -15 °C. When he determined that colder temperatures were needed, he added the CCP-31 cascade attachment to reach -40 °C. With a cascade system each cascade stage acts as a heat sink for the stage above it. This allows the top stage to reach colder temperatures.
TECA offers two and three stage cascade systems for reaching temperatures as low as -60 °C (LHP-1200C31).
