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:
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 |
| FHP-2250 | 1250 | 0.85 | (48) | 8 |
| 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 |
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.
