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.

A research organization had a problem with overheating of their equipment in a chemical-vapor deposition reactor TECA’s AHP-301CPV Cold Plate cooled the equipment and improved the performance of the customer’s system.
The customer was able to avoid system failures, which allowed the completion of a research project.
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.
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.
Below are few pictures of the “Canadian Fog Box” that our customer constructed using TECA’s AHP-300CP cold plates, power supply, and TC-3400 PID controllers.
The interior of the box is covered with mirror finished aluminum to reflect the ultraviolet rays from the bulb in the bottom. The top is normally closed as well. The interior ambient temperature of the box is maintained @ 122 °F. subjecting the 2 insulated glass units (laying at a 45° angle) to intense UV radiation similar to strong sunlight. The upper portion of the glass is chilled to 70 °F. by your cold plates. This is maintained for 1 week 24 hours/day.
The insulated glass unit is then inspected for any condensation inside where the cold plates contacted the glass. Any condensation indicates impurities present inside the unit, which indicated faulty materials containing volatile gasses, which would lead to premature window unit failure.
Any other ‘fog boxes’ use water flow cold plates to maintain temperatures. Our customer during a research found TECA’s cold plates and decided to give them a try to eliminate the hassle and mess of water plates.
The thermoelectric cold plates (Peltier cold plates) have performed excellently to date, reaching and maintaining the 70 °F. quickly and without incident.
The WWW brings many to TECA’s door. These particular customer requirements were filled by an AHP-300CP Peltier cold plate. He needed to control the temperature of a 96 well titer plate in a new product design. But he needed just a few things the standard unit didn’t provide and he didn’t need some that it did provide. He wanted a 24 VDC heat cool system with continuous fan operation and a custom tap pattern on the cold plate.
In short order the TECA sales team assigned a preliminary part number, passed the requirements through to engineering and together the first units were modified and shipped. This gave the customer plenty of time to work with the solid state cold plates and refine his requirements into the custom design he uses today.
The AHP-300CP series is now replaced by a newer and more efficient model the AHP-470CP series.
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.
A company that offers a broad range of door and window components and related building products with proven product lines and a multi-state collection of modern manufacturing facilities uses the AHP-150CP in a Canadian Fog Box, for testing double pane windows for condensation.
The AHP-150CP has been replaced by a newer and more efficient model the AHP-250CP series.
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.
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.
