DESCRIPTION

ASHRAE 90.1 COMPLIANT

YORK® Predator® MagnaDry™ units are convertible single packages with a common footprint cabinet and common roof curb for all 7-1/2 through 12-1/2 ton models. All units have two compressors with independent refrigeration circuits to provide 2 stages of cooling. The units were designed for light commercial applications and can be easily installed on a roof curb, slab, or frame.

All Predator® MagnaDry™ units are self-contained and assembled 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. Inde- pendent economizer designs are used on side and down dis- charge applications, as well as all tonnage sizes.

Predator® MagnaDry™ units are available in the following configurations: cooling only, cooling with electric heat, and cooling with gas heat. Electric heaters are available as fac- tory-installed options or field-installed accessories.

The Predator® MagnaDry™ provides energy-savings, effi- cient removal of moisture through a balanced coil design. Because the unit doesn’t increase sensible cooling, it allows temperatures to be maintained within the comfort zone. Unlike competitive systems, you’re not subjected to over cooling. You save through more efficient matching of dehu- midification and cooling needs. This makes the MagnaDry™ perfect for applications that need to remove large amounts of moisture or maintain low humidity levels.
