AIR-COOLED CONDENSING UNITS
YJ-30, -40 & -50
30 THRU 50 NOMINAL TONS
Description
These units are completely assembled, piped and wired at the factory
to provide one-piece shipment and rigging. Each unit is pressurized
with a holding charge of Refrigerant R-410A for storage and/or ship-
ping.
The compact design, clean styling, low silhouette, and quiet operation
make these condensing units suitable for almost any outdoor location.
On rooftops . . . because they weigh much less than a single package
unit of similar capacity and are much easier to rig and support. At
ground level . . . because their ample sub-cooling capacity allows them
to be located three or more stories below the evaporator coil.
Every condenser coil is pressurized with air to 325 psig and leak
tested. After assembly, the unit is pressurized with a combination of
Refrigerant R-410A and nitrogen to 450 psig for pressure testing and
additional leak testing. During this pressure test, the operation of the
high pressure control is checked. As the unit is being evacuated and
dehydrated, the operation of the low pressure control is checked.
Every compressor, condenser fan motor, crankcase heater, and elec-
trical control circuit is checked to assure a trouble-free start-up and
years of reliable operation.
The condenser fan guards are vinyl-coated to provide additional rust
protection and to enhance the appearance of the unit.
Compressors are mounted on rubber isolators to reduce the transmis-
sion of vibration. Vertical discharge condenser fans direct sound
upward and away from any surrounding structures.
All sheet metal parts are constructed of commercial grade galvanized
steel. After fabrication, each part is thoroughly cleaned to remove any
grease or dirt from its surfaces. The external parts are coated with a
powder paint to assure a quality finish for many years. This UL
approved coating system has passed the 750-hour, 20% salt spray
test per ASTM Standard B117.
All models include a 1-year limited warranty on the complete unit. An
additional 4-year extended compressor warranty is available as an
option on all models.
A matching line of Evaporator Blower units is also offered to meet your
precise capacity and air handling requirements.
