Thru Mount Thermoelectric Air Conditioners MAA150T-12/24 The MAA150T-12/24 Thermoelectric air conditioners are designed for electronic cabinets and environmental chambers. They can cool to 72˚F below ambient or maintain ambient temperatures while removing up to 150 BTU/Hr (@ 77˚F ambient). These models are available in 12 or 24 VDC configurations. Because there is no air exchanged between the cabinet and the ambient, the MAA150T-12/24 series are ideal for NEMA 12 requirements. These air conditioners are virtually maintenance-free, with no filters to change, and they can be mounted in any orientation, offering design flexibility with solid-state reliability.
