Where Are All the Cold Plates?

Cooling micro-organisms in a lab:

Recently, a prestigious U.S. university’s research lab contacted TECA. The team needed to cool a 340-well micro plate. Their vendors had many hot plates to offer, but no one seemed to offer a like product for cooling. The lab team was happy to discover TECA products online and the AHP-301CPV proved to be the right fit.

The lab’s 340-well plate is filled with a solution housing micro-organisms. To get the organisms to migrate to the bottom of the wells, the lab needed controlled cooling to 0degC. However, there is a limited temperature range in which the organisms do not degrade so precise control was paramount.

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.

Three AHP-1200CPV Cold Plates are running continuously and in tandem at 17 °C to monitor satellite equipment. The customer has added air deflectors of his own design. TECA offers standard air deflectors as well. The customer applies approximately 50 watts of heat to the cold plate.

COOLING MOUNTING WAX

Cooling Mounting Wax:

A product design engineer at a medical device company needed a way to cool wax blocks holding film. The wax is printed directly onto the customer’s aluminum tray. Before discovering TECA products, the customer was placing the aluminum tray in a refrigerator and mechanically removing the wax by scraping it off with a metal blade.

TECA’s AHP-1200CP Cold Plate is a better solution. The customer is happy to have found an affordable cold plate to dedicate to his cooling task.

Please view the video provided by our customer to see how quickly and easily the wax is now removed (no more scraping!).

COOLING WAFER

Cooling Wafer:

The adjustable feet on this AHP-1200CP Peltier cooling plate (thermoelectric cooling plate) made life easier on the factory floor.

Customer wafers needed cooling at the end of processing and the feet brought the cold plate up to the perfect height to match the production mechanisms. Just a little option that TECA is ready to provide to make the products we build work for you.

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.

QUICK COOLING OF A LOAD FROM 100 °C

A company specializing in hydrogen fuel cell technology required fast cooling of a fixture. The fixture is bonding multiple thin materials and can be heated up to 100 °C. The fixture needed to be cooled to the point where it could be handled by technicians—within a 5 minute time frame. Using two AHP-1200CP Cold Plates from TECA, the customer has created a system where a heat sink is cooled on one AHP-1200CP Cold Plate while a hot fixture is sandwiched between a second AHP-1200CP Cold Plate and a pre-cooled heat sink.

The customer reports being very happy with the TECA Cold Plates—the system is cooling in about 4 minutes!  The AHP-1200CP Cold Plate is an economical, easy to use product when maximum cooling is required, without a temperature controller. 120 VAC, 240 VAC and 24 VDC versions are available.

INDUSTRIAL ADHESIVE COOLING

Industrial Adhesive Cooling:

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.

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.
