Shown here is a prototype cooling solution for an outdoor payment device. Located in a desert environment, overheating is a big issue in the summer months. TECA’s AHP-270XE serves the requirement nicely. The energy saving “ECO mode” control feature means that passive cooling is utilized as temperatures rise. Only in the highest demand time does the active cooling component turn on. The AHP-270XE’s small size is ideal, leaving enough room inside the enclosure for other components. Thermoelectric technology means a reliable, low maintenance cooling solution with virtually no maintenance costs. The customer can expect years of trouble-free, reliable cooling. The customer reports, “Our cooling solution has been very successful so far this summer.”

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.

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:

Cooling Input/Output Racks

Drywall Manufacturing: Cooling Input/Output Racks

Several FHP-2250 Air Conditioners are used by our client to keep I/O racks within the operating temperature during peak ambient temperatures. Located in a dusty, high ambient industrial environment, our client originally tried cooling the control cabinets with fans and filters. However, with the ambient temperatures reaching 120F, the I/O racks faulted. Our client has half a dozen gas burning drying chambers, with a TECA FHP-2250 enclosure cooler mounted to each chamber’s control cabinet. The TECA solution is, in our client’s words “best for high ambient, low maintenance and dusty conditions to control interior temperature of these cabinets”.

A big benefit of the FHP-2250 is its flush-mounted design. Since there is not intrusion into the enclosure, equipment is not disturbed, and retro fitting is easy. A closed loop system maintains NEMA-4/4X enclosure ratings. The FHP-2250 is available in several configurations:

Model Number Cooling Capacity
BTU/HR		 COP Voltge
VAC (VDC)		 Current
AMPS
FHP-2250 1220 0.83 120 3.6
FHP-2250 1250 0.85 (24) 15

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.
