AIR COOLED MA

FLUID COOLING

Mobile MA Series

BRAZED ALUMINUM CONSTRUCTION

Features

Bar and Plate Brazed Aluminum Core

Rugged, lightweight, and compact

Provides the best heat transfer per

given envelope size while minimizing

pressure drop

Air-side ﬁn design minimizes fouling

and static pressure ensuring long-

term, reliable performance

Fan motor assembly has an IP68 with

AMP-#180908 connection

Welded aluminum ﬁttings/ports and

manifolds ensure structural integrity

Standard SAE ports – NPT and BSPP

ports available

Customized units are available to

meet your speciﬁc performance

requirements

Additional capabilities for radiators,

charge-air-coolers, condensers, and

multi-circuit units
