Cooling control panels outdoors:
Our customer operates a wastewater treatment plant for a large municipal sanitation district. Operating some of the plant’s equipment is a large-process industrial air compressor. The air compressor’s controls are housed in an outdoor cabinet. Taking advantage of TECA’s NEMA-4, flush-mounted design, the customer has TECA Model FHP-1501XE mounted to the control cabinet. When ambient temperatures rise, the FHP-1501XE keeps the heat-sensitive controls cool while maintaining the cabinet’s NEMA-4 rating. The flush mount design is convenient for the end user because the cabinet’s contents do not need to be disturbed or rearranged to accommodate the air conditioner.
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
|FHP-2250 (High Capacity)||1715||0.39||120||10.8|
|FHP-2252 (High Capacity)||1875||0.35||240||6.5|
|FHP-2250 (High Capacity)||1610||0.66||(48)||15|
A flow testing facility required precise heating and cooling of a NEMA-4 enclosure in an outdoor application. The customer’s NEMA-4 instrument box houses very sensitive transducers and data acquisition equipment.
TECA Model AHP-1200XEHC paired with the TC-3400 remote temperature controller protects the enclosure’s contents from extreme temperatures in the ambient. The customer can monitor and set the controller without opening the NEMA-4 enclosure. Custom programming achieves exact set points as specified by the customer. The sealed, industrial grade external fan allows for wash down of the enclosure and exposure to the outdoor environment, all while maintaining a closed loop system.
TECA Model AHP-1200XE air conditioners cool over 30 outdoor electronic information kiosks in dozens of State Parks in the U.S. Our customer launched the first electronic interpretive information program specifically designed for visitors to a State Park system by implementing the kiosks.
This award-winning project has received significant attention across the country and TECA is proud to be part of it. The AHP-1200XE can be customized to fit your kiosk’s needs.
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.
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.
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.
The applications for AHP-1802XE’s are Vestas wind turbines, one located in Greece and one in the south of Japan.
“We are installing sensitive measurement equipment, and need to control the inside temperature of the measurement panel. One panel is in each of the rotors in the hub and the two others are in the nacelles (rotating and non rotating). We have just decided to make the two panels into one in the nacelle (where the panel in not rotating).”
Intermodal systems are increasingly upgrading to automate their processes. Where there is automation, there is a need for control cooling. TECA supports automation by protecting crucial electronics in control cabinets. This minimizes process time and maximizes productivity.
In this example, heat-sensitive electronics are installed in truck processing terminals. TECA Model AHP-1800XEHC offers heat and cool modes and keeps the equipment within safe and operable temperatures.
