INCUBATOR COOLING

by

Incubator Cooling / Insect Rearing Chamber:

Incubators used in the rearing of insects for research often experience thermal failures due to the acids inherent in the biology of the insects. The acidic environment that insects create can quickly corrode a standard, compressor-based cooling system- even if its copper coils are coated. High humidity adds to the problem because droplets of concentrated acid will collect on the cooling components.

The solid-state nature of TECA’s thermoelectric air conditioners solves the problem offering reliability and virtually maintenance-free operation.

A published life science researcher from a local university contacted us because he experienced several failures from his compressor-based air conditioner units. He is raising flies in an incubator, and requires an accurate set point. The TECA Model AHP-1200 Thermoelectric Air Conditioner is the perfect solution. The air conditioner keeps the incubator to 18C as the customer requested. Using a remote, programmable temperature controller (TECA Model TC-3400) the customer is getting the accuracy he needs and the convenience he wanted from a remote controller.

ANALYZER COOLING, HARSH ENVIRONMENT

by

Analyzer Cooling, Harsh Environment:

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.

PORTABLE SECURITY EQUIPMENT

Site monitor and security equipment for oil fields and transfer stations needed more security. A portable enclosure housing cameras, WI-FI access, antennas and a Mac Mini computer inside leveraging the Mac platform to provide virtually instant access, hi speed, via “Wild Blue”. The system will be like a watchdog that they can strap on wherever they need the monitoring.

With a slight modification an AHP-1200XE thermoelectric cooler provided the best solution while keeping the NEMA-4 rating of the enclosure.

FOOD PROCESSING

A European manufacturer of special equipment for processing fruits and vegetables needed to cool sensitive electronics on their line of produce-processing machines, which sort products by color, size and weight.

TECA Model AHP1200XE solid state air conditioners were selected.

The equipment in use is washed down frequently, so the Model AHP1200XE is ideal because it is designed to meet NEMA 4 and suitable for wash-down environments, while it also carries the CE Mark.

RUGGEDIZED MILITARY APPLICATION

Sometimes it just takes a long time to get to the heart of a problem. AHP-1200X “quick quote” for two thermoelectric air conditioners came into our sales team. It was responded to and followed up. The application was reviewed, a quote was made and an order placed.

Only after did we learn that the hard requirements they were looking for were:

  1. Dual adjustable temperature control (heat and cool)
  2.  28 VDC operation and
  3. Military environment.

Fortunately the selections within TECA’s enclosure air conditioner family are large. The military Contractor borrowed a unit from TECA’s loaner stock and based on that success, placed an order. It was then that we found a problem.

It seems that the application was to cool some sensitive electronics out on a 200 meter DC input which caused droop in the input which in turn caused a ringing in the circuits. The new digital monitors being used were susceptible while the older tube monitors had no issue.

Working with the customer it was determined that by changing the controller to a ruggedized PWM controller all problems were solved.

MILITARY PROJECTOR

A ruggedized enclosure for a military video projector caused excessive heat to build up from the high wattage bulb.

A more rugged version of TECA’s AHP-1200FF thermoelectric cooler / solid state air conditioner is used by military to cool a projector.

PAPER MILL

The environment of a paper mill is hostile to most equipment. Could a thermoelectric cooler stand up to such conditions?

TECA Model AHP-1200X Solid State Air Conditioner is a perfect solution. This TECA model AHP-1200Xwas returned to TECA for evaluation, after over 120,000 hours of duty. It just did not seem to cool as much any more. As a matter of fact, it was originally put to work in 1992 cooling an electronic enclosure in a paper mill. The customer was sure it needed to be replaced, but sent it back to us to see if anything could be salvaged.

In our inspection we found that the hot side heat sink was fouled with 14 years of newsprint sludge. Once the goop was cleaned out and the fan was free to spin; the unit ran like a charm!

RUGGEDIZED FOOD PROCESSING

The maker of some of our favorite corn chips used TECA’s AHP-1200X for years in severe hose down environments.

They now had a similar requirement where they wanted to minimize any cleaning and were willing to entertain a liquid cooled LHP-1200XE solid state air conditioner. The unit fit into the same area and footprint as its air cooled cousin and provided greater cooling capacity. This customer added a valve on the water inlet to provide water flow only when cooling was required.

The units have been in service for years.

Fire Safety Switches & Alarm Enclosure

TECA provides standard off the shelf as well as custom designs to meet the needs of the end user. Alarm enclosures can be exposed to some of the harshest conditions like the extremes of live-fire heat and hose-down. The alarm enclosure pictured here is for fire safety and switches. The transparent plastic enclosure is accessible and secure while being cooled to desired temperatures under harsh firefighting conditions. In this example TECA provided custom modifications to provide for redundancy and mounting requirements specified by the end user.

Contact teca@thermoelectric.com to inquire about custom designs for your needs. Our friendly sales team looks forward to hearing from you!

 

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.
