ANODIZING ALUMINUM

Anodizing Aluminum:

anodizing aluminum
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.

MEDICAL

Medical Application:

The customer needed a compact thermoelectric cooling system to cool flow of fluid through removable membrane liquid jacket used in a mobile medical application. TECA’s sales and engineering team worked with the customer and developed the product you see in the pictures above for the exclusive use of our customer.

The application is medical and will be protected by patent. Thermoelectric cooling will be employed for effective cooling of the brain for emergency treatment of stroke victims.

BEVERAGE COOLING

Here’s more of the engineers dream test job (beverage cooling). The team was messing around and decided to cool a keg with a TLC-700 liquid chiller and one of our medical customers water pads used for patient temperature therapy. Instead of the patient laying down on the pad they wrapped it around the keg and then insulated it.

Not quite an economical way of cooling your beer. But they did use the mattress the next day to sleep off the hangovers.

CALIBRATION

Calibration:

A commercial laboratory uses TECA Chiller TLC-1200HC to discourage temperature gradients in a calibration system. Utilizing the built in temperature controller, the customer was able to successfully run the input and output to a temperature difference of zero. Designing a suitable calibration method was critical to the customer’s ability to release a new product to market.

The photos here illustrate the compact size of TECA’s TLC-1200HC.

LIQUID CHILLER COLD PLATE CASCADE

Liquid Chiller Cold Plate Cascade:

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.

SEMICONDUCTORS

Cooling Semiconductors:

A research oriented organization uses TECA’s TLC-900 recirculating liquid chiller to control the temperature of a semiconductors test stage where proximity of TEC would produce electromagnetic noise hard to screen.

Temperature controlled fluid supplied by TLC-900 keeps their test stage cooled and free of noise.

TESTING PROPERTIES OF MATERIALS

Testing Material Properties:

testing material properties

A materials scientist at a state university uses TECA’s TLC-900 Liquid Chiller to cool transducers for an elastic modulus apparatus. The apparatus measures the elastic modulus as function of temperature. The elastic modulus is a material property. It defines the stiffness of material. It varies with temperature and is used in design.

The customer uses the TLC-900 Liquid Chiller to cool a plate, which then cools from 400C to between 30C and 50C.

STIRRING COLD PLATE

Stirring Cold Plate:

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.

COOLING FLUID FLOW

Cooling Fluid Flow:

A customer needed to cool high pressure flow of fluid in a single pass. Using expanded Aluminum foam and attaching it to the surface of AHP-301CP thermoelectric cold plate (peltier cold plate) provided a way to maximize the thermal contact surface and eliminated the need to complex fluid path and larger cold plate.

BEVERAGE COOLING IN A BARREL

Beverage Cooling in a barrel:

Here’s an application that TECA’s engineering team was particularly excited about. Not because of the economics or the potential new business. Frankly we didn’t think the market was there. But as soon as they found out that a ½ barrel of beer would be needed for testing they were all over it. While none was ever sold, good lessons regarding contact methods and material stratification were learned. To see the result of the test click here.
We used an AHP-1200CP thermoelectric cold plate and a TLC-700 thermoelectric liquid chiller for testing purpose.
