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.

AEROSPACE MANUFACTURING

Aerospace Manufacturing:

liquid chiller for aerospace manufacturing application

 

To meet an Aerospace manufacturing customer requirement TECA sales and engineering team modified a standard model chiller to meet a highly specialized demand of the application, including liquid cooling, 24 VDC input and wall mounting. This recirculating liquid chiller was developed for a customer who needed something similar to the TECA LHP-300CP chiller; but it had to be a liquid cooled liquid chiller – it had to be 24 VDC input – and it had to be mounted on the wall!

The application is X-Ray inspection of aircraft engine parts. Temperature controlled water is circulated through a heat exchanger which is keeping photo diodes nice and cool, assuring quality X-Ray imaging.

CUSTOM MILITARY LIQUID CHILLER

Military Liquid chiller:

Here’s another custom military application by TECA.

Military grade liquid chiller

 

The United State Navy needed a liquid chiller to circulate coolant and also meet strict military requirements. TECA developed a custom thermoelectric liquid chiller using MIL rated components. This is a liquid chiller for circulating chilled coolant as part of a tracking system on a NAVY ship.

Note that the chilled liquid circuit is effectively “sandwiched“ between two heat sinks with rugged Mil 901 fans. Wiring and electrics are housed in a NEMA-4X enclosure with an O-ring gasket seal. This unit is rated for shipboard use in salt-spray, shock and vibration.

MEDICAL

Medical Application:

medical cooler

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

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.

LIQUID CHILLER WITH 200′ HOSE

Liquid Chiller with 200′ Hose:

Liquid chiller with 200' hose

A customer wanted a TLC-1400 thermoelectric liquid chiller (Peltier chiller) to maintain a 400 watt load under normal conditions except for one thing, the hose needed to be over 200’ long. Would it pump? How much of an effect would it have on the cooling capacity? We could have run the numbers and come up with an estimate.

It was really easier to just hook up some hose and a constant load plate, roll it into the environmental chamber and see what it did. It did more than it was supposed to. The customers safely bought it knowing it would do what he needed.

CHILLING PROCESS INK

Chilling Process Ink:

Here’s the way they’re all supposed to work:
September: Initial contact: Need help sizing unit that can maintain a liquid temperature between 25 °C – 35 °C in ambient conditions of 15 °C – 40° C. I need a unit for testing ASAP. In conjunction with sizing a chiller, I am also trying to size a heat exchanger. I need chiller flow rate and output temperature. Please call to discuss details.

CALIBRATION

Calibration:

calibration using TLC-1200HC liquid chiller calibration with liquid chiller

 

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:

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.
