Protecting PLC Equipment in a Hazardous Environment

TECA’s legacy product, Model AHP-1800XPHC has been installed in over a dozen (to date) specialty cabinets by a process safety engineering firm.

Our customer shared with us:
“We asked a client for a preferred vendors for the thermo electric coolers and TECA was given to us. We have been pleased with the products and service your company has given.”

Our customer serves refineries and chemical plants, implementing critical safety control systems. With both outdoor and indoor needs, TECA Model AHP-1800XPHC can be used in either environment, and it can maintain a cabinet rated for CID2 explosion-proof. Among the sensitive equipment TECA’s enclosure cooler protects is a group of programmable logic controllers (PLC). The PLCs need to be reliable, safety certified, and able to withstand rugged conditions. The stakes are high in this application. The CID2 “Hazardous Location” enclosure coolers offered by TECA include safety certification, mil-grade external fan, and a decades-long track record with customer like this one.

Copper Heat Sink

Copper Heat Sink : Modification to a standard product

Thermoelectric panel cooler with copper cold side sink

A chemical analysis service provider used TECA’s thermoelectric air conditioner as part of a larger system. The end user required copper heat sinks instead of aluminum heat sinks. TECA provided this modification to a standard product, the AHP-270XE. This is one example of modifications TECA can accommodate, including black anodizing of aluminum parts, using 316 stainless steel instead of 304, and much more.

Environmental Chamber For Testing Asphalt

How Strong is That Asphalt?

TECA’s thermoelectric air conditioners are often used in industrial settings to keep control equipment cool. This application, however, shows another side of TECA’s enclosure coolers. Used in research laboratories across the country, TECA enclosure coolers have cooled incubation chambers, sensitive test equipment, glove boxes, and the like. Here is another example of a TECA thermoelectric air conditioner being used in the lab:

A customer manufactures a range of glove box systems for atmosphere control applications in clinical and industrial environments. TECA air conditioners are a vital component on a variety of the glove box models that this customer produces. Standard and customized versions of TECA air conditioners from the AHP-1800 Series are used to control the glove box temperature to below ambient.

Clinical applications primarily revolve around cell and bacterial studies within cancer research, bio-fuels studies, sleep apnea, anaerobic microbiology research and clinical applications etc.

Industrial applications include product weighing or assembly with humidity and temperature maintenance.

INCUBATOR COOLING

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.

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.
