Laird Technologies’ AA-250 Outdoor Cooler Series use impingement flow and custom designed thermoelectric modules to transfer heat. Designed for outdoor enclosures, this product line cools battery back-up systems that are susceptible to degradation when exposed to elevated temperatures or heats when exposed to very cold temperatures. The standard product offering is open loop and comes in 24 or 48 volt configurations. The series requires no maintenance, resulting in a low total cost of ownership. It is mountable in the vertical or horizontal orientation with optional control of airflow direction on the cold side.
