BEVERAGE COOLING

Beverage cooling:

beverage cooling with TLC-700 thermoelectric liquid chiller adn water pad

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.

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.

COOLING FLUID FLOW

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.

AHP-800MSP STIRRING COLD/HOT PLATE

R & D LABORATORY

R & D Laboratory:

r & d laboratory
An R&D laboratory needed to quickly cool beakers of high-concentration sucrose samples to 10 °C.  The customer reports that using TECA’s AHP-800MSP Magnetic Stirring Cold/Hot Plate system has been successful.

The customer has different sizes of samples, which are accommodated by TECA’s sleeve accessories. The customer uses 2L, 1.5L, 1L and 800mL sleeves at different times with the AHP-800MSP system. The sleeves are easy to switch in and out and add versatility to the system.

In fact, unique to this product is the adjustable nature of many of its features: stir-bar speed, fan speed (for noise reduction), and temperature sensing (internal or external).

CHEMICAL VAPOR DISTRIBUTION SYSTEM

Chemical Vapor Distribution System:

130-tlc-900

An OEM customer integrates TECA’s Model TLC-900 Liquid Chiller into a bubbler system designed to distribute chemical vapor via a carrier gas. The bubbler vessel is filled with the liquid chemical. The carrier gas is bubbled through the vessel and TECA’s TLC-900 Liquid Chiller maintains the chemical at a temperature determined by the end user, to maximize process control. The customer chose TECA’s TLC-900 Liquid Chiller over others because of its heating and cooling capability and the versatility of its universal input voltage (100-240 VAC). The customer’s system is sold worldwide and quality and reliability are key. The customer shared with us: “Before we used TECA products, we had half a dozen failed units over in China that my boss had to fix. I’m talking chillers that have only been in service for less than 4 months. In all, there have been at least ten of them go bad over the years. Some of the current orders we have with you are replacement units for the failed ones. We love your products. You are putting the competition to shame. Keep up the good work.”

COSMETIC TREATMENT

42-tlc-700
Photofacial treatments using intense pulsed light are said to remove spider veins and age spots, but are uncomfortable for the patient. The apparatus shown uses a TECA Model TLC-700 Peltier based liquid chiller to cool the tip of the hand piece which rests on the skin area under treatment. This enhances the comfort of the patient; allowing for a better quality treatment. The chiller is a closed loop system so no water gets on the patient or the instruments. Water temperature is closely adjustable over a wide range.
