AC-055 Peltier-Thermoelectric Air Cooler
• Ideal for small to medium-sized electronics enclosures and refrigeration applications
where a large temperature difference is not required.
• NEMA 4 protection: anodized external fins, environmentally sealed external fan (IP55),
and stainless steel finger guards.
• Low-profile internal fan minimizes the space required inside the enclosure.
• Internal fan blows air to center of enclosure so you can aim cooled air at the
components that need the most cooling.
• Adaptable mounting - can be mounted in any orientation and fan end of internal fins
can be placed against enclosure wall if needed.
• Energy efficient / low input power.
• Heats as well as cools (when used with heat & cool / bipolar controller).
• 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.

Performance is based on unrestricted air flow to fans and
from air-flow outlets. Do not operate if the ambient,
enclosure air, heat sink, or cold sink temperatures exceed
60 °C. Do not operate fan at air temperatures below -10 °C

1Current, at steady-state, is rated at +25 °C ambient, +25 °C internal, maximum heat removal. At -10 °C internal, the typical steady-state current is 5.34 A.
2Current, at steady-state operation under-worst case conditions, is rated at -10 °C ambient, +60 °C internal, maximum heat removal.

Example: You need to maintain the enclosure at 40 °C while in a 50 °C ambient. The cooler can remove a maximum of
approximately 46 W of heat from the enclosure. If the heat load (internally generated heat plus the heat gain through
insulation, solar, vapor condensation, etc.) in the enclosure exceeds this, you would need more coolers and/or a larger
cooler.
