UAT-C_(i)
Component Features
Compressor
High ef
fi
ciency, low noise, and hermitically sealed
SCROLL compressors are used in the UAT-C series
to give a better performance.
All compressors are equipped with an internal
overload protection. Crankcase heaters are installed
as standard in each compressor.
Evaporator Coil
Evaporator coils are manufactured from seamless
inner grooved copper tubes mechanically bonded to
aluminium
fi
ns to ensure optimum heat transfer.
All coils are tested against leaks by Nitrogen holding
at 609psig and highly precise Helium leak test at
235psig.
ALL standard coils are 3-4 rows / 14-16 FPI, 3/8”
(9.52mm) O.D. tubes.
Evaporator Fan
The unit is designed with belt driven evaporator
motor, which allows for change of pulley on site to
accommodate different static pressure and air
fl
ow
requirement.
Condenser Coil
Condenser coils are manufactured from seamless
inner grooved copper tubes mechanically bonded to
aluminium
fi
ns to ensure optimum heat transfer. All
coils are tested against leaks by Nitrogen holding
at 609psig and highly precise Helium leak test at
235psig.
ALL standard coils are up to 3 rows / 14-16 FPI, 3/8”
(9.52mm) O.D. tubes.
Options:
Hydrophilic Gold Fin coating (NA549) condenser coil
is offered as option, which has longer life span under
corrosive environment.
Condenser Fan/Motor
Fans are of propeller type, direct driven by
weatherproof electrical induction motors. Condenser
fan motors are
rated IP55 protection index with
class F insulation class
and is designed with
dust
proof bearing
to ensure the reliability of the motor
and smooth operation all year round.
Casing/Structure
The unit casing used in UAT-C series is made of zinc
coated galvanized steel sheets. It is further coated
with an electrostatic powder coat, oven-baked for a
tough and lasting weather resistant
fi
nish. Zinc plated
screws are used to further reduce the possibility of
unit rusting.
