AC-055

Capacity Rating: 55 watts at a 0°C temperature difference.
Example Applications: Ideal for small to medium-sized electronic enclosures or refrigeration applications when a large temperature difference is not required.
Features: Powered by 12 VDC, has a low power draw, and maintains an enclosure’s NEMA 4 rating. Low profile internal fan blows air into center of cabinet for directed cooling. The low power consumption makes this cooler compatible with all of our temperature controllers. Can be used for heating and cooling. Can be customized for production-sized orders.

Capacity Rating: 55 watts at a 0°C temperature difference.
Example Applications: Ideal for small to medium-sized electronic enclosures or refrigeration applications when a large temperature difference is not required.
Features: Powered by 12 VDC, has a low power draw, and maintains an enclosure’s NEMA 4 rating. Low profile internal fan blows air into center of cabinet for directed cooling. The low power consumption makes this cooler compatible with all of our temperature controllers. Can be used for heating and cooling. Can be customized for production-sized orders. Labeled wiring cables are included free of charge when purchasing interconnected standard products on the same order (thermoelectric cooling assembly or module, temperature controller and/or a power supply). The number of cables included (1-3 pairs) will depend on the number of components being interconnected.

• Ideal for small to medium-sized electronic enclosures or refrigeration applications when a large temperature difference is not required.
• Weatherized protection: anodized external fins, environmentally-sealed external fan, and stainless steel finger guards.
• Maintains enclosure’s NEMA 4 rating (IP-55 external fan).
• Low-profile internal fan minimizes the space required inside the enclosure.
• Energy efficient / low input power.
• Can be used for heating and cooling (requires heat/cool controller).
• Adaptable mounting – can be mounted in any orientation and fan end of internal fins can be placed against enclosure wall if needed.
• Internal fan blows air to center of enclosure so you can aim cooled air at the components that need the most cooling.
• High quality dual ball bearing fans for long life.
• Can easily be customized for production-sized orders to meet your exact requirements.
• CE marked, RoHS compliant.

The AC-055 thermoelectric (Peltier) air cooler is specially designed for cooling electronics enclosures when a large temperature difference from ambient is not required. While not specifically designed for refrigeration it can be used in these applications as long as a large temperature difference below ambient is not required. It can, as with all of our coolers, both heat and cool when used with the proper temperature controller.

The AC-055 is environmentally protected: the hot-side fan is sealed against moisture and dust (IP55), the external heat sink is anodized to prevent corrosion, and the finger guards are stainless steel. The unit is rated to maintain an enclosure’s NEMA 4 rating.

A low-profile internal fan minimizes the amount of internal volume required by the cooler. Internal air is pulled primarily through one end of the fins and blown out the fan towards the center of the enclosure. This configuration allows one end of the internal fins to be placed close to the wall of the enclosure without hindering performance, and the equipment that needs the most cooling can be located in the cooled air stream.

The AC-055 is powered by 12 VDC and works with all of our temperature controllers. If more capacity is needed, or there is a need to distribute the cooling throughout a larger cabinet, multiple coolers can be paralleled and regulated by one temperature controller. The electrical connections are located on the internal side of the cooler keeping wiring inside the enclosure. (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.)

The AC-055’s low power consumption yields low operating costs. As an added benefit the power supply will generate less waste heat, meaning the power supply has less of an impact when located inside the enclosure.

Note: Larger power supplies are used when controlling multiple units with one temperature controller.

NOTE WHEN DOWNLOADING FILES: When saving a solid model some browsers change the name of the file extension. If this happens save the file to your computer using the “Save link as…” option and then rename the file extension back to the appropriate type before using. (PC Users: Right click on the file link and select “Save link as…” from the menu. Mac Users: Hold the ‘Ctrl’ button on your keyboard while clicking on the file link and select “Save link as…” from the menu.) Alternatively, you can download as normal and rename the .htm or .html extension back to .x_t or .stp before using.
