Liquid Cooled Cold Plate

Newest Liquid Cooled Cold/Hot Plate LHP-1800CPV:

Liquid Cooled cold/hot plates have the freedom from the noise and vibration of fans. Water works as the coolant, carrying heat away from the cold plate source. TECA’s newest liquid-cooled cold/hot plate is also its largest. The LHP-1800CPV features a 15.2” X 19.2” footprint and a range from -30C to +130C (high temperature version). A water source is required. The LHP-1800CPV is ideal when powerful cooling is needed in a small footprint.

High Speed Crystal Oscillators:

High Speed Crystal Oscillators

The customer makes high performance crystal oscillators and atomic clocks for satellites and laboratories and they needed something for temperature control and stabilization.

They found TECA and the AHP-301CPV, tried one and say it is “working fantastic”. Well enough to order more for production, quality and engineering tests. They use them to maintain a stable temperature of the oscillator which in turn provides a stable frequency.


Performance Testing:

Customer needed to test low-temperature performance of inertial measuring devices.  In this application of low temperature thermoelectric cooling; the user is testing inertial measurement devices over a temperature range.

The devices as well as the TECA cascaded cooling assembly are subjected to various rotational and acceleration stimuli while device temperature is controlled.  The custom thermoelectric cold plate cascaded (Peltier cascade) was built up from a standard Model AHP-301CP cold plate.

The finished test fixture was able to function with a maximum rotation rate of 1700° per second and 50 g acceleration.  The rotation is evident in the photo. By using a standard product as the basis for the cooling system, higher costs associated with a custom solution were avoided.


OEM Laboratory Equipment:

As a component in an OEM laboratory chamber, the AHP-150CP condenses out moisture to control humidity. The chamber is primarily used in hospital laboratories. The small size of the AHP-150CP helped reduce the footprint of the chamber and helped increase the work space within the chamber.

The AHP-150CP is maintenance free and the reliability of its thermoelectric cooling technology made our smallest cold plate the perfect OEM solution for this customer.

The AHP-150CP has been replaced by a newer and more efficient model the AHP-250CP series.


Cooling Gas FLow:

A potential customer expressed interest in a cooling/heating system for an aerosol flow tube envisioning a 1 inch OD, 0.875 inch ID stainless steel flow tube mounted inside a 2-2.5 inch ID pipe (likely also stainless steel and insulated on the outside) capable of controlling the tube at temperatures ranging from roughly 5 °C to 40 °C at an ambient temperature of 25-30 °C.  We are measuring the change in particulates in the air due to the temp change.

Standard liquid chillers were first offered along with technical design assistance. The requirements led to direct contact cooling as being a good solution. Standard cold plate products and controllers were offered which led to this request for a custom package. “We would like to have the flow tube sandwiched between the cold plates with the temperature controller and power supplies attached in a similar manner so that we only need attach the temperature controller (the TC-3400 appears as if it will work) to a computer so that we can change the set points remotely.

Is any of this even possible or am I dreaming in Technicolor?” We advised him that the best dreams were in color. Preliminary design work was done and a quote prepared. Shortly thereafter an order was received; design documents were completed and sent to production. Less than 3 months after the initial contact the product was shipped. Several months later a follow up was made with this response.

“Things are doing really well. It does exactly what we wanted it to do, and is much more efficient and better than we hoped for. We’re very happy!

ERGO-900 Histology Cold Plate
“You did an awesome job listening to our needs and recommendations to create a product that was lacking in the Histology world. I’m pleased to tell you that we are happy with the size, look, and performance of this unit. The cold plate surface is a nice size and reaches -6 degrees C in a timely manner and maintains this temp. This is a preferred temp to chill our paraffin blocks for optimal microtomy.The fan is quiet and only produces a small amount of airflow out the side and back. AWESOME job!!!!!! Everyone is loving it!!!!”

Pam.R., Histology Laboratory Manager


“TECA occupies a unique place in the cooling industry. In harsh environments and/or mission-critical applications, performance trumps cost.”

“About 20 years ago, [TECA was] recommended to us. Over the years, I have purchased 3 units…Two were removed after ~9 years of flawless service and [one unit] is still working (outdoors!) after ~15 years of service.”

M.H. Califonia Institute of Technology

“It beats the heck out of the system that is currently being used…This thing is working beautifully. Everyone is most impressed. Thanks!!!”

R.Z., Penumbra

“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.”B.E., Norcimbus OEM

“We were extremely appreciative of the opportunity to try the TECA Cascaded Cold Plate system. We will certainly mention your product to any colleagues who do more frequent dissection work. It was incredibly kind of you to offer the loaner and to take the trouble to make sure that it worked properly for our application.”

“We used the system to facilitate dissection. It was important for us to maintain the integrity of the specimen during dissection. Working in a lab at normal room temperature, we found that a constant temperature of -18C was ideal for this work. It would have been impossible to maintain such a precise temperature outside of a cryostat without the TECA cold plate. It was immensely easier to perform the dissection on the TECA cold plate, and of course also much easier to wipe down the cold plate than to clean a cryostat. We would recommend the TECA cold plate system to any scientist who needs to dissect frozen tissue in any precise manner. Anyone who was doing this regularly would find it an excellent investment because of the time and trouble it saves.”

D.L., Stanford University

“I wanted to extend the Navy’s sincere appreciation for your excellent service and response time. TECA provided a timely and economical quotation for fixing a component that is critical for development of materials of interest to the Navy. TECA has saved the Navy thousands of dollars that would have been incurred due to delays in production. The excellent customer care received by your organization is rare and we wanted you to know how much we appreciate your efforts. We hope you pass this to your management and everyone involved so that they all know that good customer service is very much appreciated and desired.”

J.S., U.S. Navy
