DESCRIPTION

YORK

 Predator

®

 MagnaDRY™ units are convertible single 

packages with a common footprint cabinet and common roof curb 
for all 7-1/2 ton models.  All units have two compressors with inde-
pendent refrigeration circuits.  The units were designed for light 
commercial applications and can be easily installed on a roof 
curb, slab, roof jack, or frame.

All  Predator

®

 MagnaDRY™ units are self-contained and assem-

bled on rigid full perimeter base rails allowing for 3-way forklift 
access and overhead rigging.  Every unit is completely charged, 
wired, piped, and tested at the factory to provide a quick and easy 
field installation.

All units are convertible between side and down airflow.  A single 
economizer design is used on side and down discharge applica-
tions, as well as all tonnage sizes.

The Predator

®

 MagnaDRY™ provides energy-savings, efficient 

removal of moisture through a balanced coil design. Because the 
unit doesn’t increase sensible cooling, it allows temperatures to 
be maintained within the confort zone. Unlike competitive sys-
tems, you’re not subjected to over cooling. You save through more 
efficient matching of dehumidification and cooling needs. This 
makes the MagnaDRY™ perfect for applications that need to 
remove large amounts of moisture or maintain low humidity levels.
