Cooling Variable Frequency Drives

Steel Mill Enclosure Cooling:

A major steel company has multiple equipment enclosures, housing 4 variable frequency drives (VFD) each, to control their industrial cranes. The high temperature in the steel mill was causing excessive shutdowns. Compressor-based air conditioners could not survive the electrical enclosures’ harsh ambient environment on the overhead cranes. The only input power available was a widely varying 250 VDC, which complicated things. TECA successfully and affordably customized a flush-mounted (external to enclosure) thermoelectric air conditioner to meet the customer’s needs.

Satellite Communication – Long Service Life:

A testament to TECA quality and reliability, this image shows a 130 foot radio telescope at a research observatory. The red arrow indicates the location of the the TECA air conditioner. TECA’s AHP-1200 is installed there to control the temperature of a 2′ x 2′ x 4′ insulated electronics box . The AHP-1200 runs continuously, 24/7, to control the internal temperature to about +25C. The ambient temperatures range between -10C to +40C.

Thermoelectric Cooling for TACAN (Tactical Air Navigation) System

TACAN (Tactical Air Navigation) System uses Thermoelectric Cooling:

Thermoelectric Cooling for TACAN (Tactical Air Navigation) System     thermoelectric panel coolers

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.

GAS CHROMATOGRAPHY SYSTEM

Gas Chromatography System:

Gas Chromatography System 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:

In the images shown here, TECA Model AHP-1800XE Thermoelectric Air Conditioner is being used successfully to cool electronics in an outdoor kiosk. The desert environment where the kiosk is located sees temperatures upwards of 110 F.

Outdoor kiosks are growing in popularity but typically require more from an active cooling system than their indoor counterparts. Outdoor kiosks have heat generating equipment like LCD screens and computers. In addition, there can be solar loads and high ambient temperatures to contend with. TECA offers many sizes of enclosure coolers for outdoor use, all utilizing low maintenance and reliable thermoelectric cooling technology.

Our customer raves about the results of this TECA-cooled kiosk, “I had not even one maintenance call. During the summer time the surface of the kiosk gets as high as 125 F, and the components were running cooler than the components in our indoor kiosks.”
