Component Features
Compressor
High efficiency, low noise, and hermetically sealed
SCROLL compressors are used in the UATN-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 fins to ensure optimum heat transfer.
All coils are tested against leaks by Nitrogen holding
at 609psig and highly precise Helium leak test at
235psig.
Hydrophilic Gold Fin coating evaporator coil
is
offered as standard, which could give good effects to
efficient drainage of condensate water as well as heat
transfer performance, and gives superior corrosion
protection even in the harshest environment especially
in coastal area. (1000 hours Salt Spray tested)
Evaporator Fan
The unit is designed with belt driven evaporator motor,
allows for change of pulley on site to accommodate
different static pressure and air flow requirement.
This flexibility allows for wider application and offers
the possibility to reach the best working conditions
considering the unit’s characteristics. The fan motor is
I
P55 rated protection index with class B insulation
class
.
Condenser Coil
Condenser coils are manufactured from seamless
inner grooved copper tubes mechanically bonded to
aluminium fins 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.
Hydrophilic Gold Fin coating condenser coil
is
offered as standard, which gives superior corrosion
protection even in the harshest environment especially
in coastal area. (960 hours Salt Spray tested)
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 UATN-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 finish. Zinc plated
screws are used to further reduce the possibility of
unit rusting.
Coil Guard
The condenser coil is protected by coil guard to
prevent accidental damage during transportation,
handling and installation.
