Cooling control panels outdoors:
TACAN is a radio system which can provide aircrew with navigation and bearing information. A market leader in military solutions uses TECA Model AHP-1800XHC as a standard component to provide cooling to their mobile TACAN system. AHP-1800XHC is well designed for this type of application. For reliable performance under harsh conditions, we use military-grade sealed fans and components on the hot side (external to enclosure). The AHP-1800XHC heats and cools as needed without maintenance or repair down time. This has been crucial for our customer, who markets their mobile TACAN system as self-sufficient.
TECA has been designing and manufacturing for harsh military environments for decades. Contact us to discuss your our solutions for NEMA-4X and Shock & Vibration.
Our customer operates a wastewater treatment plant for a large municipal sanitation district. Operating some of the plant’s equipment is a large-process industrial air compressor. The air compressor’s controls are housed in an outdoor cabinet. Taking advantage of TECA’s NEMA-4, flush-mounted design, the customer has TECA Model FHP-1501XE mounted to the control cabinet. When ambient temperatures rise, the FHP-1501XE keeps the heat-sensitive controls cool while maintaining the cabinet’s NEMA-4 rating. The flush mount design is convenient for the end user because the cabinet’s contents do not need to be disturbed or rearranged to accommodate the air conditioner.
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:
Several FHP-2250 Air Conditioners are used by our client to keep I/O racks within the operating temperature during peak ambient temperatures. Located in a dusty, high ambient industrial environment, our client originally tried cooling the control cabinets with fans and filters. However, with the ambient temperatures reaching 120F, the I/O racks faulted. Our client has half a dozen gas burning drying chambers, with a TECA FHP-2250 enclosure cooler mounted to each chamber’s control cabinet. The TECA solution is, in our client’s words “best for high ambient, low maintenance and dusty conditions to control interior temperature of these cabinets”.
A big benefit of the FHP-2250 is its flush-mounted design. Since there is not intrusion into the enclosure, equipment is not disturbed, and retro fitting is easy. A closed loop system maintains NEMA-4/4X enclosure ratings. The FHP-2250 is available in several configurations:
|Model Number||Cooling Capacity
|FHP-2250 (High Capacity)||1715||0.39||120||10.8|
|FHP-2252 (High Capacity)||1875||0.35||240||6.5|
|FHP-2250 (High Capacity)||1610||0.66||(48)||15|
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.
TECA Model AHP-1200FFHC was chosen by our customer to provide thermal management to an ATM kiosk.
Electronics components often require cooling AND heating. The TECA cooler provides both heating and cooling to the kiosk. This ATM kiosk will be installed in dozens of locations with the TECA air conditioner, AHP-1200FFHC.
Thermoelectric technology is a reliable and low maintenance way to protect electronics. Utilizing the Peltier effect, TECA enclosure coolers (and heaters) do not require coolant, chemicals, compressor or filter.
TECA Model AHP-1801XPHC-1 Thermoelectric Air Conditioner is used to enable the safe installation of a gas chromatography system into hazardous locations. Most installations are rated Class 1, Groups C & D, Division II. However in some cases the installations require Group B and/or Group A. TECA’s AHP-1801XPHC-1 maintains the interior of the Process Analyzer Enclosure at a control temperature of around 70o °F. It meets the various requirements of all the installation environments.
This system is installed in Refining, Petrochemical, Upstream and other applications requiring the aforementioned safety ratings. Controlling the temperature of the equipment enclosure rather than the entire shelter allows for far more economical plant installations even in very cold or very hot environments.
Our customer reports:
“Simply protecting our Process Analyzer Enclosure from direct sunlight and precipitation is enough using the AHP-1801XPHC-1. The TECA Air Conditioner has plenty of capacity to handle the most demanding environments such as the Texas Gulf Coast and even in Alberta, CA. See the actual plant installation picture where 3 Process Enclosures are shown. The TECA Air Conditioners are clearly evident below each analyzer. These units have been in operation for more than 2 years without maintenance, without downtime. This says a lot about the capability and capacity of the TECA product in a tough environment. And the analyzers have performed flawlessly delivering control quality composition data to the plant process control computer.
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.
A custom design solution based on a standard thermoelectric air conditioner AHP-1801X was developed to meet European hazardous environment specification (ATEX) for a customer that was in need of such a system in a very short time.
