Featured Customer Testimonial

Every TECA success begins with a customer. We value our customers and are grateful for their feedback.

“I’m using this opportunity to thank you for the support. Regarding the heat (cold) plates from TECA, we have plenty of them. They have been used in a series production of Galileo satellites and honestly

all work excellent. TECA plates are very useful for our project and there are plenty of experiments where we use them.Your advice helped me to create a MATLAB script and my test-bed is working perfectly. I’m very satisfied with the functionality of these heat plates, and will definitely recommend them to our customers and companies we are working with. Thank you very much once again.”Engineer, European Space Agency

“…testing is going well. The folks here commented at how much quieter your fans are overall and at how light the chassis is compared to the old system*….”

John F., Design Engineer
*Teca’s note: the TECA product replaced a competing “old system”, as the customer referred to

“With your guided suggestion we have completed integration of our system. Our system is running well. I appreciate your assistance! It is very kind of you!”

Jason Z., Design Engineer

“During my search for a cooling system, I discovered your company, but never did I expect the level of kindness you have offered. It is individuals like yourself and your company that provide great opportunities for non-profit organizations to survive, especially military non-profits. Not all understand what non-profits are all about. For us, it is about giving so that others in the future will learn and reflect on what took place in history. Again, we can’t begin to express our most sincere appreciation to you for your more than generous donation of the a/c unit. Thank you for your generous offer to support our foundation’s efforts to maintain one of America’s most beautiful Veterans Memorial Parks.”

Pete M., Operations Officer

“I was certainly pleased with your customer service and the performance of your product. All of our TECA coolers are doing quite well also. In fact, I haven’t had to think about them at all since they were installed!”

Jerry W., Senior Engineering Technician

“I wanted to let you know that the AHP-301CPV is working wonderfully for my daughter Lisa’s science fair project. She just completed her first data collection run and her results are interesting. She figured out how to use the device quickly and it has been rock solid for her. Lisa programmed the cold plate to cool the crystals, which were placed in copper cups, at 2 degrees Celsius per minute from room temperature to -20 C. Thanks in part to TECA, Lisa qualitatively reproduced the results of a paper in the journal of Science. She got an ‘A’ on her science fair project. She has also presented her experiment at a lab at MIT, where they may use it as part of their undergraduate course.”

Parent of Lisa.R., Student

“The reason we chose Thermoelectric was due to the excellent customer service provide by TECA. I was looking for a chiller to replace a model that we had been using since the early 1990’s by a company which has since gone out of business in the past several years. I was unable to locate a similar chiller and when I called TECA, it was offered that TECA may have a liquid chiller that they could modify to emulate the chiller previously used as far as function and interface. We have already generated interest with our sister site who is also looking for a replacement for the same application for the same reason.”

Steve, Radar Systems Manager

“BTW…After searching around I think you have a very cool product line at a very competitive cost!  It’s nice to see a company finally thinking outside the box…”

Vince, Application Engineer

“Thank you so much for the very fast shipment! Our scientists are very happy and feel they are excellent condition and quality! Thank you for your help, it’s been a true pleasure working with you.”

Dawn, R&D Strategist

“The [ERGO-900] cold plate has worked wonderfully for us so far. It cools down very quickly when you turn it on and it is ready to use within minutes. It can hold approximately 40 blocks, it maintains its temperature well, it is quiet, and it takes up very little space. We are greatly enjoying it! Thank you so much again.”

Hannah, Histology Technician

“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 plates are very useful for our project and there are plenty of experiments where we use them…you can be sure I will recommend them to a large number of companies we are working with.”

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
