YORK ZJ Series Sunline Magnum™ /ZR Series
MagnaDRY™/ZF Series Sunline™ units are convertible single
package high efficiency rooftops. All models have independent
refrigeration circuits for efficient part load operation.
Although the units are primarily designed for curb mounting on
a roof, they can also be slab-mounted at ground level or set on
steel beams above a finished roof.
All ZJ/ZR/ZF units are self-contained and assembled on rigid
