Cooling a NEMA-4 Enclosure with Precision

Cooling a NEMA-4 Enclosure with Precision:

Cooling a NEMA-4 Enclosure with Precision   Cooling Enclosure
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.

ATM KIOSK COOLING

ATM Kiosk Cooling:

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.

KIOSK COOLING

Kiosk Cooling:

A company specializing in fleet management and motor pool software required multiple outdoor, self service kiosks to be placed in various environments throughout the USA. TECA’s AHP-470XEHC thermoelectric air conditioner is an ideal solution, providing needed cooling to sensitive parts within the sun-exposed kiosk. The AHP-470XEHC air conditioner cools the kiosk without taking up much space and it is suitable for various environments including NEMA-4 enclosures. Heat/Cool is optional, as are external covers for aesthetic purposes.

Whether space is restricted inside or outside your kiosk, TECA offers three mounting styles for kiosk cooling: Through, Internal and External.

OUTDOOR KIOSK COOLING

Outdoor Kiosk Cooling:

TECA Model AHP-1200XE air conditioners cool over 30 outdoor electronic information kiosks in dozens of State Parks in the U.S. Our customer launched the first electronic interpretive information program specifically designed for visitors to a State Park system by implementing the kiosks.

This award-winning project has received significant attention across the country and TECA is proud to be part of it. The AHP-1200XE can be customized to fit your kiosk’s needs.

GAS CHROMATOGRAPHY SYSTEM

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.

COMMUNICATIONS

Communications, Cooling Battery Bank:

Maintain the temperature of a battery bank in a Class 1 Division 2 explosion proof environment to power portable communications equipment. A special purpose vehicle manufacturer needed to maintain the temperature of a bank of batteries to maintain maximum performance.

With our recommendation, the customer selected the TECA Model AHP-1800XP, because it is the only NEMA4X air conditioner available off-the-shelf, which is also certified for C1D2 use. The power source was able to meet the requirement of operation in a Class 1 Division 2 explosion proof environment, to support portable communications systems at car racing venues.

HAZARDOUS ENVIRONMENT

Hazardous Environment:

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.

CORROSIVE ENVIRONMENT

Corrosive Environment:

The AHP-1802XPHC-2 met the customers need in an application where other similar products could not function due to extreme corrosive environment.

The TECA design team in a short notice was able to provide a solution based on a standard AHP-1800X thermoelectric air conditioner.

MILITARY

Military Application:

Outdoor Electronics Enclosure Cooling:

Mean Time Between Failure (MTBF) Test Outdoor Electronics Enclosure Cooling

 

TECA Model AHP-1800XEHC Thermoelectric Air Conditioner with heat and cool functions is installed on a rooftop enclosure in harsh conditions and exposed to extreme ambient temperatures. Testing for over 90,000 hours was successfully completed with no failures occurring on the AHP-1800XE enclosure cooler. This is a good example of the reliable nature of thermoelectric technology. Thermoelectric cooling is a good choice for enclosures that are in remote or hard-to-access places. There is very little maintenance required as it is a solid-state technology. The only moving parts are the fans.
