• High efficiency design.
• Multiple units can be operated by one temperature controller.
• Protected against harsh environments --meets Bellcore, NEMA and IP specifications.
• Removes 140 watts (475 BTU/hr) from an enclosure while maintaining internal temperature at ambient temperature.
• Can be used with our IP-65 rated (outdoor) power supply.
This cooler is specially designed for low power consumption and high efficiency. Its intent is to remove heat from an enclosure while maintaining the internal temperature at or near ambient--it is not typically used to achieve refrigeration temperatures. So, this cooler is ideal for applications where the goal is to prevent an electronic equipment enclosure from overheating. It can, as with all of our coolers, both heat and cool when used with the proper temperature controller.
The low power consumption yields low operating costs and also means that the cooler’s power supply will generate less waste heat. Thus, the power supply has less of an impact when it is located inside the enclosure. Want to mount the power supply outdoors, outside of the enclosure? An IP-65 rated power supply (model PS-24-10 IP-65) is also available.
The cooler is powered by 24 VDC and works with a wide range of temperature controllers. If you need more capacity, or need to distribute the cooling throughout larger cabinet, you can parallel multiple AC-140 coolers and have them all regulated by one temperature controller. The power input wires are routed on the cold side of the cooler and make it easy to connect the wiring from inside the enclosure. (As always care should be taken so that condensation is not allowed to form on the cold side heat exchanger where it could come in contact with the power wires.)
Finally, the AC-140 incorporates environmental protection. The hot-side fan is sealed against moisture, the heat sink uses marine-grade anodizing to prevent corrosion, and the unit is rated to maintain the enclosure's NEMA 4 rating.
Note: Larger power supplies are used when controlling multiple units with one temperature controller.

3D MODEL: Click on the link above to download a 3D model. You can rotate and view the cooler from any angle to better understand the physical properties of the product. (However, wire leads are not shown in the model.) This is a portable document format (.pdf) file, Adobe Acrobat 8 or higher is all that is required for viewing. You may be prompted by Adobe Acrobat to do a one-time upgrade to Version 8.0 or for 3D model support components. 3D content may initially appear as a two-dimensional preview image. Clicking the 3D model with the Hand or Select tool enables (or activates) the model and opens the 3D toolbar.Please email us (cool@tetech.com) if you need STEP files of the 3D model.
