Protecting PLC Equipment in a Hazardous Environment

TECA’s legacy product, Model AHP-1800XPHC has been installed in over a dozen (to date) specialty cabinets by a process safety engineering firm.

Our customer shared with us:
“We asked a client for a preferred vendors for the thermo electric coolers and TECA was given to us. We have been pleased with the products and service your company has given.”

Our customer serves refineries and chemical plants, implementing critical safety control systems. With both outdoor and indoor needs, TECA Model AHP-1800XPHC can be used in either environment, and it can maintain a cabinet rated for CID2 explosion-proof. Among the sensitive equipment TECA’s enclosure cooler protects is a group of programmable logic controllers (PLC). The PLCs need to be reliable, safety certified, and able to withstand rugged conditions. The stakes are high in this application. The CID2 “Hazardous Location” enclosure coolers offered by TECA include safety certification, mil-grade external fan, and a decades-long track record with customer like this one.

Copper Heat Sink

Copper Heat Sink : Modification to a standard product

Thermoelectric panel cooler with copper cold side sink

A chemical analysis service provider used TECA’s thermoelectric air conditioner as part of a larger system. The end user required copper heat sinks instead of aluminum heat sinks. TECA provided this modification to a standard product, the AHP-270XE. This is one example of modifications TECA can accommodate, including black anodizing of aluminum parts, using 316 stainless steel instead of 304, and much more.

Radar Rack Cooling

Radar Rack Cooling:

TECA Model AHP-2259XEHC enclosure cooler is being used to cool data racks on a radar system for military use. The AHP-2259-Series can be powered from 90-264 VAC. The universal input feature makes for easy ‘plug and play’ use in various global locations. Ideal for outdoor applications, power efficiency is increased by as much as 10% in higher ambient temperatures. The AHP-2259-Series can be configured to boost cooling performance or power efficiency, depending on the goals of the end user. Also notable is TECA’s exclusive ECO Mode temperature control feature. This passive cooling feature significantly reduces the need for active cooling, and thus reduces amp draw and the overall cost of ownership.

Environmental Chamber For Testing Asphalt

How Strong is That Asphalt?

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:

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.

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

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.

PORTABLE SECURITY EQUIPMENT

Portable Security Equipment:

Site monitor and security equipment for oil fields and transfer stations needed more security. A portable enclosure housing cameras, WI-FI access, antennas and a Mac Mini computer inside leveraging the Mac platform to provide virtually instant access, hi speed, via “Wild Blue”. The system will be like a watchdog that they can strap on wherever they need the monitoring.

With a slight modification an AHP-1200XE thermoelectric cooler provided the best solution while keeping the NEMA-4 rating of the enclosure.
