Cooling a NEMA-4 Enclosure with Precision:

A flow testing facility required precise heating and cooling of a NEMA-4 enclosure in an outdoor application. The customer’s NEMA-4 instrument box houses very sensitive transducers and data acquisition equipment.

TECA Model AHP-1200XEHC paired with the TC-3400 remote temperature controller protects the enclosure’s contents from extreme temperatures in the ambient. The customer can monitor and set the controller without opening the NEMA-4 enclosure. Custom programming achieves exact set points as specified by the customer. The sealed, industrial grade external fan allows for wash down of the enclosure and exposure to the outdoor environment, all while maintaining a closed loop system.

Large LCD Screens:

Specializing primarily in the food and beverage processing industries, one of our longtime customers uses TECA air conditioners in several applications. These include cooling or heating LCD screens, desktop computers, thin clients, and KVM kiosks. The locations of these applications are indoors, outdoors, in cold rooms and baking areas.

TECA’s comprehensive line of air conditioners fit the bills. We offer each model in different configurations according to the customer’s need regarding input voltage, mounting and application environment.

Electronics Enclosure Cooling:

Customer plans to use the TEC unit to regulate the temperature of some electronics in an outdoor enclosure. The electronics will be mounted to a cold plate where they can be cooled by direct contact with the TEC. The walls of the enclosure will be insulated to reduce thermal losses to the outside world. The hot side of the TEC will be in a separate, ventilated part of the enclosure to carry away waste heat. Customer will provide longitudinal air flow along the heat sink, so the built-in fan will not be necessary.

Originally considered using a solid-state air conditioner to cool the entire enclosure, but now prefers the direct-contact method for lower cooling requirements and smaller size. The active load that needs to be cooled is about 50 W. It will consist of a number of RF components (amps, sources, etc) mounted to a common cold plate. Several passive components will also be mounted to the plate. The whole temperature-controlled assembly will be insulated by an inch or so of foam or something similar. The ambient temperature range is roughly 0 to 100 °F at the extremes.
