Thermoelectric Assembly Air-to- Air Cooler ｜Compact DC Peltier Cooling Unit AA-125-24, China Thermoelectric Assembly Air-to- Air Cooler ｜Compact DC Peltier Cooling Unit AA-125-24 Manufacturers, Suppliers, Factory

P&N's AA-125-24 Thermoelectric Air Cooling system delivers reliable enclosure temperature control for precision applications. This compact air-to-air solution provides up to 125W of cooling capacity (ΔT=0) with 24V DC operation, making it ideal for medical diagnostics, industrial systems, and analytical instruments where quiet, maintenance-free performance is critical in space-constrained environments.

Engineered with P&N’s high-reliability thermoelectric modules and dual-fan design, the unit ensures efficient heat dissipation without liquid circulation. Its robust construction supports long-term operation under ambient conditions from -10°C to 60°C, while fan MTBF exceeds 50,000 hours. The AA-125-24 fits within a 232×124mm panel cutout, delivering flexible integration into precision-controlled environments such as photonics housings and portable analyzers.
