These folks needed to cool a thick fluid that ends up being gaskets when robotically dispensed. A custom version of our AHP-1200CP fit the bill perfectly. Now the product is dispensed consistently because of the temperature control provided by thermoelectrics.
The people at MIT who wanted a custom cold plate with plain black anodized cold plate never did tell us what it was for. We think maybe they are using it to calibrate or adjust infra red temperature detectors. We could be wrong. They might have thought it just looked cool.
For whatever reason, they told us what they wanted and we did our best to meet their requirement.
A branch of the US military had an overheating problem with a high-tech radio inside the wing of a fighter aircraft. TECA developed a custom, high-performance cold plate that withstand the shock, vibration, and G forces created by one of the most technically advanced aircraft.
In order to assure maximum strength with minimum weight, TECA’s Advanced Machining Center machines the finned heat sinks for each cooler from a single blocks of material
Portable medicine cooler needed for carrying emergency intravenous solutions, all components must be enclosed within the case. TECA designed a custom thermoelectric (peltier) based cold plate built into a Pelican™ Box.
TECA is developing this product for a new customer. We have taken a standard Pelican™ Box and configured a battery powered thermoelectric cooling system which is installed totally inside. This cooled box is for the purpose of transporting up to 4 liters of emergency intravenous solutions safely.
There are fitted compartments inside as well for transporting other necessary items for patient care. Since nothing is exposed or protruding from the box, our customer has ended up with a good looking and very rugged, functional thermoelectric product.
At a prominent U.S. university, neuroscience research team choose TECA’s economical AHP-270CP Cold Plate.
The customer reports: “We cool a fly to 8 deg Celsius, and also use vacuum to attach it to the device during a brain dissection procedure. Essentially, the cooling is anesthetizing the fly, making it possible to attach the fly to the dissecting chamber in a very precise manner, using a manipulator (also in the picture).” The AHP-270CP is a great solution because it is small, inexpensive and yet offers reliable and effective cooling on the bench top.
A European company specializing in equipment for the continuous flow chemistry market required extreme temperatures for a new product. Integrating a customized version of TECA’s Liquid Cooled Cascaded Cold Plate made the customer’s product possible: they are able to reach temperatures from minus 70 °C to plus 80 °C.
The customer reports that their new continuous flow reactor allows for the use of flow chemistry in many applications, achieving quicker results safely and with better control.
We used TECA’s AHP-1200CAS three stage cascaded thermoelectric cold plate system to facilitate dissection of frozen human postmortem brain slices for extraction of protein for Proteomics research. Because we were trying to select specific regions without damaging the rest of each small specimen, it was important for us to maintain the integrity of the specimen during dissection.
Working in a lab at normal room temperature, we found that a constant temperature of -18 °C was ideal for this work (-20 °C was too cold, and warmer than -18 °C made the tissue start to melt). It would have been impossible to maintain such a precise temperature outside of a Cryostat without the cold table. It was immensely easier to perform the dissection on the cold table, and of course also much easier to wipe down the cold table than to clean a Cryostat.
Here are pictures of the TLC-900 thermoelectric liquid chiller with LHP-150CP Peltier liquid cooled cold plate set up run in the lab. The “load” is a plate with 10 power resistors mounted to the top and a series of thermocouples measuring the surface of the LHP-150CP’s thermoelectric cold plate.
During the test the power to the resistors is increased in steps with enough time in between for the temperatures to stabilize. Plotting the data resulted in performance curves. The test was made with the load insulated and with the load simply covered.
Later on we used a TLC-900CAS, a version of the TLC-900 made specifically for running and controlling secondary cold plates like the LHP-150CP and ran some step, ramp and soak profiles.
The beverage cooler application challenge was to keep concentrated beverage container located next to a hot water tank cool in a high volume OEM application. TECA has the flexibility and resources to manufacture custom OEM thermoelectric cooler (peltier coolers) assemblies intended for use as part of a customer machine, apparatus, or system. This OEM assembly is made by TECA in production runs in the thousands. It is not ours, so to protect the privacy and identity of our customers we can’t give too many details here.
This assembly is part of a beverage service product which is shipped worldwide by a well known consumer products company. TECA furnishes the cooling “engine” which refrigerates the beverage product to be dispensed, and the OEM builds finished machinery in their own plants.
A Peltier stirring cold plate was needed to cool liquid inside a standard 1000 ml plastic tank and maintain the class 100 clean room rating. They desired a custom designed thermoelectric stirring cold plate with integral variable stir speed control, temperature control, alarm and remote sense capability.
TECA is glad to participate in custom and OEM product development. Over the years we have come up with some innovative and novel solutions for our customers. This product was developed from scratch for a start-up company in the field of pharmaceutical development. This TECA cold plate apparatus was designed and built for use in a clean room facility. The controls are ergonomic. The user can easily adjust controls for stir speed, timing and temperature even while wearing clean room garb and sterile gloves.
