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.

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.
