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.

TIGHT TEMPERATURE CONTROL

Tight Temperature Control Within Small Enclosure:

A manufacturer of specialty materials required cooling and heating of small enclosures. The system pictured here is used for the mixing of helium and hydrogen with dew point control.

TECA Model AHP-301FFHC is used with a TECA PID temperature controller to regulate the temperature of the enclosure in order to establish the moisture content of the “wet gas”, which is blended with dry gas to fix the dew point by way of the Buck Equation.

The customer is pleased with the results and continues to build more systems using TECA air conditioners and temperature controllers.

the AHP-301FF series is now replaced by newer model the AHP-401 series.

COOLING LARGER ENCLOSURES

Cooling Larger enclosures Than Ever Before:

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.

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.

COOLING MEDICINE IN TRANSIT

Cooling Medicine In Transit:

A customer designs and installs custom systems for public safety vehicles. TECA’s AHP-1800-Series Air Conditioner was the perfect fit for keeping medicine cool in transport and in the field. With multiple input voltage and environment configurations available, the customer will be using more TECA air conditioners in other vehicles.

The tight mounting space shown in these photos illustrates the value of thermoelectric air conditioners. There are no filters to change, no chemical coolants and there are no moving parts except the fans. The customer can expect years upon years of service from this unit, virtually maintenance free!

KIOSK COOLING

Kiosk Cooling Application:

Pictures above show a 4 year-old outdoor kiosk that is located in a zoo in the Sonoran Desert. The kiosk holds a computer and LCD screen, both generating heat, both mounted within an inch of each other. This active heat load coupled with the high ambient temperatures create a significant need for cooling. TECA’s model AHP-1800XE Thermoelectric Air Conditioner has proven to be a reliable solution.

Our customer raves “I had zero problems in past years, not even one tech. call. During the summer time here, when outside temperatures reach 95-110 °F, and surface of the kiosk gets as high as 125 °F, the LCD, computer and other components were running cooler than the components in our indoor kiosks.”

COOLING GLOVE BOXES

Cooling Glove Boxes:

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.

ROBOTICS

Robotics Application:

robotics

An industrial plant uses robots in its juicing and bottling process. The robots continuously overheat and shut off. The environment is dirty and 240 VAC is the only available input voltage.

TECA’s AHP-1801X Air Conditioner offers dual voltage capability and a rugged hot side fan that can handle NEMA-4X and corrosive environments. The customer is able to use the built-in temperature controller to keep his robots at a cool 25 °C.
