COOLING LARGER ENCLOSURES

by

Cooling Larger enclosures Than Ever Before:

cooling larger enclosures

A user of the Model AHP-6250 Solid-State Air Conditioner gives a wonderful example of the benefit of TECA’s newly introduced line of high-capacity thermoelectric air conditioners.

Designed to cool larger enclosures than was previously practical with thermoelectric technology, the AHP-6250 is one of the largest models in this group. For example, the enclosure pictured here is about 8 x 6 x 3 feet. The customer is able to achieve large enclosure cooling with a single thermoelectric air conditioner. Thermoelectric cooling is reliable and maintenance free.

TECA’s new high-capacity line has some thoughtful design features, as seen pictured here on the installed AHP-6250. The cold side (internal to enclosure) has a low profile, which translates into less intrusion into the enclosure, giving the user more room for whatever the enclosure is meant to hold. The robust mounting flange, gasket and hardware and centrally located power input contribute to user-friendly installation. Finally, high air-flow fans and high fin-density heat sinks on the cold side maximize performance and minimize condensation. An integral condensate removal system absorbs condensation and transports it to the hot side, where it gets evaporated into the ambient.

ANALYZER COOLING, HARSH ENVIRONMENT

by

Analyzer Cooling, Harsh Environment:

analyzer cooling

TECA’s Model AHP-1202XEHC Thermoelectric Air Conditioner provides accurate heating and cooling for the customer’s analysis machine. The environment is harsh: it is in a cement plant.

The customer’s product quickly analyzes composition of raw materials, allowing for increased productivity. TECA’s AHP-1202XEHC provides reliable thermal management within a harsh environment. The AHP-1202XEHC has an industrial grade sealed fan and sealed hot side components, allowing for frequent wash down (NEMA-4).

The solid-state construction is the perfect low-maintenance solution for hard-to-access areas. There are no filters to change and no moving parts except for the fans.

TECA air conditioners use robust thermoelectric modules and boast a long service life.

LAB MEASUREMENT EQUIPMENT

Lab Measurement Equipment:

A world’s leading international supplier of equipment, controls and parts to glass container industry uses the peltier air conditioner model FHP-750XE in a statistical sampling and lab measurement product.

A MiniLab Automatic Sampling installation works in conjunction with the production’s online inspection equipment and a Factory Process Control System. The MiniLab Controller communicates to the Process Control System which then sends a container “request” to upstream online inspection systems equipped with mold number readers. The “requested” containers are transferred to the MiniLab sampling conveyor using container ware selectors. With broad-based expertise in glass container forming, glass conditioning, gob forming, ware handling, cold end inspection, refractory parts and quality assurance, the company’s machines and systems are established as standard products worldwide.

The FHP-750 has been working fine for them for years. Reasons for its selection are its reliability and ability to operate in high ambient temperatures.

AVIONICS MAINTENANCE

The task was to create a portable cooling system for diagnostic equipment to allow troubleshooting of avionics systems while still installed. Troubleshooting and diagnosing avionics problems is hard enough on the bench.

To save valuable time, technicians would rather get it done while the electronics are still in the aircraft. Also, under harsh environments, it is difficult to keep cutting edge electronics functioning the way they should. When it came to the type of portable cooling for the diagnostic equipment required for these jobs; a navy contractor came to TECA for the solution.

We helped design and build the solution shown in its prototype form around the portable enclosure. TECA completed the project on a tight schedule, which called for teamwork and attention to detail.

MILITARY TROOP TRANSPORT

It was 1994 and a military contractor came to TECA with a problem. The existing Freon based refrigerators used in troop transport galleys had a MTBF measured in months.

They had recognized the potential of thermoelectrics and contracted with a vendor to design and build refrigerators for them.  The problem came when the original vendor’s product failed to live up to its potential. TECA was approached and given only several months to design, build and test three prototype refrigerators for the first new galley.

Less than three months later with test data in his hands and three refrigerators in the back of his truck a TECA rep delivered the goods. Over twenty years later the military and it’s allies around the world are still flying these same refrigerators and ordering more.

CONSUMER ELECTRONICS

They manufacture navigation devices for land, road, trail and water and they needed to evaluate circuit boards @ various temperatures (-30 °C to -40 °C, no or minimal heat load, room temperature ambient) and on recommendation of a person who joined them from a controls company and had been using the solid state cold plate AHP-1200CAS. The system required the cold plate, cascade, cascade control and tapped plate. The tapped plate is built into the cold plate in place of a smooth plate surface to attach to the cascade plate.

The cascade control facilitates power and temperature control to the cascade. The system also included an acrylic cover and insulation block. They received the system and liked how it is built.

THEME PARK EXHIBIT

Theme Park Exhibit:

A company specializing in 3-D designs for museums, theme parks, and other attractions needed to build an “icy throne” for a museum exhibit and keep it dry at the same time.

Using four TECA AHP-1200CP Peltier cold plates (thermoelectric cold plates), one was placed in the seat, back, and in each arm rest of the throne. Raw aluminum was then screwed onto the plates, and the throne surfaces reached close to -20 °C! Visitors to the museum can sit on the throne to feel the chill. The “ice” in the picture is not real. It is a “hard coat” of scenic ice. The throne manufacturers did not want museum visitors to get wet from real ice; their goal was to create a throne.

CUSTOM COLD PLATE

Custom Cold Plate Application:

The people at MIT who wanted a custom cold plate with plain black anodized cold plate never did tell us what it was for. We think maybe they are using it to calibrate or adjust infra red temperature detectors. We could be wrong. They might have thought it just looked cool.

For whatever reason, they told us what they wanted and we did our best to meet their requirement.

BEVERAGE COOLER

The beverage cooler application challenge was to keep concentrated beverage container located next to a hot water tank cool in a high volume OEM application. TECA has the flexibility and resources to manufacture custom OEM thermoelectric cooler (peltier coolers) assemblies intended for use as part of a customer machine, apparatus, or system. This OEM assembly is made by TECA in production runs in the thousands. It is not ours, so to protect the privacy and identity of our customers we can’t give too many details here.

This assembly is part of a beverage service product which is shipped worldwide by a well known consumer products company. TECA furnishes the cooling “engine” which refrigerates the beverage product to be dispensed, and the OEM builds finished machinery in their own plants.

R & D LABORATORY

An R&D laboratory needed to quickly cool beakers of high-concentration sucrose samples to 10 °C.  The customer reports that using TECA’s AHP-800MSP Magnetic Stirring Cold/Hot Plate system has been successful.

The customer has different sizes of samples, which are accommodated by TECA’s sleeve accessories. The customer uses 2L, 1.5L, 1L and 800mL sleeves at different times with the AHP-800MSP system. The sleeves are easy to switch in and out and add versatility to the system.

In fact, unique to this product is the adjustable nature of many of its features: stir-bar speed, fan speed (for noise reduction), and temperature sensing (internal or external).
