Thru Mount Thermoelectric Air Conditioners
MAA150T-12/24
The MAA150T-12/24 Thermoelectric air conditioners
are designed for electronic cabinets and environ-
mental chambers. They can cool to 72˚F below ambi-
ent or maintain ambient temperatures while remov-
ing up to 150 BTU/Hr (@ 77˚F ambient). These mod-
els are available in 12 or 24 VDC configurations.
Because there is no air exchanged between the cab-
inet and the ambient, the MAA150T-12/24 series are
ideal for NEMA 12 requirements. These air condi-
tioners are virtually maintenance-free, with no filters
to change, and they can be mounted in any orienta-
tion, offering design flexibility with solid-state relia-
bility.
