The MAA070T-12 thermoelectric air conditioner is designed for small electronic cabinets and environmental chambers where temperature control is critical. It can cool to 72°F below ambient or maintain ambient temperatures while removing up to 70 BTU/HR (@ 77°F ambient). Because there is no air exchanged between the cabinet and the ambient, the MAA070T-12 is ideal for NEMA 12 requirements. This air conditioner is virtually maintenance-free, with no filters to change, and can be mounted in any orientation, offering design flexibility with solid state reliability.
