AC-194 Peltier-Thermoelectric Air Cooler
• Ideal for telecommunications equipment, electronic enclosures, and battery boxes
(non explosive environments only).
• Environmentally sealed external fan, anodized heat sink, and stainless steel
hardware.
• Input wires are routed on the cold side of the cooler, making it easy to power via
wiring from inside the enclosure.
• Maintains enclosure at NEMA 4 rating.
• 48 V operation.
• Can easily be customized for production sized orders to meet your exact
requirements.
• High temperature versions and customizations are available for production volumes.
• 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
70 °C. Do not operate fan at air temperatures below -20 °C

Example: You need to maintain the enclosure at 15 °C while in a 25 °C ambient. The cooler can remove a maximum of
approximately 150 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.

Example: You need to maintain the enclosure at 30 °C while in a 0 °C ambient. The cooler can add a maximum of

else generating heat), you would need more coolers and/or a larger cooler.
