Freeze Tape Casting

Freeze Tape Casting Manufacturer:

A materials science company specializes in creating foams with specific porosity for use in electric vehicles, batteries, thermal interface materials and ceramic-metal interfaces. Utilizing a TECA thermoelectric cold plate as a component within the freeze tape caster ensures the manufacturing process remains environmentally friendly. Peltier cold plates use no freon, coolants, or chemicals of any kind. In this example, the customer has slightly modified a commercially-available, off-the-shelf (COTS) TECA cold plate to reach the desired -10C set point.

CONDENSING VAPOR

Condensing Vapor: AHP-470CP in Laboratory Reactor Instrumentation

condensing vapor   cooling vapor stream

In a chemical process (catalysis), the customer uses several TECA Model AHP-470CP Cold Plates to condense methanol out of a vapor stream and collect liquid in the 100 mL glass vessels shown. The AHP-470CP offers a convenient small size and is customizable to the end user’s needs.

Please see the “Options” section on the product data sheet to learn more.

COOLING ASPHALT SAMPLES

Cooling Asphalt Samples:

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.”

CHEMICAL WASTE TRANSPORT

Chemical Waste Transport:

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.

CASCADE COLD PLATE

Cascade Cold Plate:

Here’s a step by step of an AHP-1200CAS/CCP-22 Cascade system our engineers were playing with. They took a purple EasySep magnetic nano particle vessel, set it on the cascade, insulated it and then cycled it up and down for kicks. The curve shows the results. Faster times can be achieved by thinning out the plates and building the cascade into the AHP-1200CAS rather than having it as an option.

Talk to TECA engineers if your interested.

LOW TEMPERATURE CASCADE

Low Temperature Cascade

A cascade sandwich is what we called this that day, built using two AHP-300CP cold plates. The customer needed a fairly large mass cycle between two extremes. The mass and size of the load were limiting factors. The pictures and assembly look crude, and it was, but they were also effective.

It was determined that a final design based on standard components would be successful and it was.

The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.

LIQUID COOLED COLD PLATE

Liquid Cooled Cold Plate:

Our customer asked for a quote on delivery and price for the LHP-800CPHC. He then asked if we had a liquid cooled version of the AHP-1200CPHC (15″ x 7.3″ plate)? The product had been in the works but on the back burner. This customers request pulled it to the front.

We offered an LHP1200CP. It would be liquid cooled with 15 x 7.3 cold plate requiring 24 VDC input. The customer later set it up with a water pump and a radiator/fan arrangement to provide a recirculation cooling water path rather than connecting to the tap and sending it down the drain.

COLD WELL

Cold Well:

The CWB-01 cold well was first developed as an AHP-1200CPV custom accessory for the petrochemical industry. It replaced the need to maintain ice baths for the storage of chemicals. It has the advantage of good temperature control in either heating or cooling modes. The temperature of the cold plate can be referenced to the fluid temperature or the remote sensibility feature of the CPV can be used to control based on the actual fluid temperatures.

Cold Wells can be made to accommodate many vessel sizes or the ICE-1200 accessory with TECAlab Thermal Beads works well also.
