UCUA (OUTDOOR)
AIR COOLED DUCTED SYSTEM
MODULAR DESIGN
The units are designed modular form. Multiple units’ installation for higher cooling capacity requirement.
COMPACT DESIGN
The compact design requires only minimal installation space. The units dimensions were carefully studied to maximize container space shipment.
PERFORMANCE
Single refrigerant circuit design, maximizes energy efficiency and provides superior system operating performance when connected to suitable sized UDF units.
EASY MAINTENANCE
The service-oriented design concept provides easy access to internal parts, by removing the front panel.
CABINET
All UCUA units exposed external surfaces are coated with baked polyester based powder coating, providing high-corrosion resistance. The internal components are easily accessible by removing the access panel.
COMPRESSOR
Single speed winding, scroll compressor of fully sealed hermetic type, equipped with suction vapor cooled windings, crankcase heater and internal line break motor protection. The compressor is also equipped with internal suspension system to eliminate noise and vibration.The conditioned air can be effectively distributed to every corner of the room through the ducting and this ensure a more pleasant environment for comfort living.The UCUA is equipped with state-of-the-art compressor with proven quality, thus giving the unit high capacity, good performance, better reliability and durability. Besides that, the integration of a set of high and low pressure switches in the unit provides better protection to the compressor, prolonging the compressor life span.
HIGHER EFFICIENCY
As the hot air density is lower than surrounding atmosphere, the vertical air throw of the UNIHEAT UCUA series have improved the air distribution. This in turn helped to improve the efficiency of the heat exchanger as well as avoid the hot air short circuit possibility for heat exchanger.The large coil surface area is incorporated with unique slit fins design and inner grove copper tube to increase the exchanger surface. This has helped to improve thermal transfer, providing maximum efficiency and hence boosts up the unit capacity.
LOW NOISE OPERATION
The designed of the direct drive condenser fans together with the raise fan guard helps to reduces the operating noise from the fan.Besides that, the compressor is well isolated to the housing cabinet, avoiding transmission of vibration. This also helps in reducing the sound pressure of the unit.
AIR-COOLED CONDENSER
The Condenser Coils are of 3/8” OD seamless copper tubes arranged in staggered rows, mechanically expanded into aluminium fins. The maximum design working pressure of the coil is 350 psig. The condenser fan is of high efficiency propeller type, direct driven by 3 phase, IP55, class F insulation condenser motor.
REFRIGERANT CIRCUIT
Single refrigerant circuit designs, with external copper piping and brazed joints. The unit is pressure-tested, evacuated and fully charged with Nitrogen gas (N²), and includes an initial oil charge. After assembly, an operational test is performed to ensure the refrigerant circuit is operating correctly.
UNIT OPERATION SAFETY PROTECTION
Crankcase heater, Auto reset High-Low pressure cut-out switch, double pole relay to guard against compressor damage due to high discharge head pressure and system leakage.
ROBUST UNIT
Constructed with gauge galvanized steel and powder coating paint, the UCUA is designed to resist the toughest climate and has better weather protection. This helps to established the UCUA series as a more robust unit.
WIDE CHOICES OF INDOOR UNITS
The unit is capable to couple with various indoor units such as wall mounted, ceiling cassette, ceiling convertible and ceiling concealed split unit. With these wide ranges of indoor choices, the system can meet all kind of application and blends easily to any interior design.
AUTO RANDOM RESTART
Whenever unit stops due to power failure during operation, unit automatically restarts at the last setting condition once the power is resumed. However, the compressors will restart randomly if more than one unit is installed and share the same phase of power. Option is provided to cancel this feature.
FILTERS
Nominal 1-inch thick washable flat filters of 75% - 80% arrestance supplied as standard item.
SEQUENTIAL CONTROLLER AS STANDARD
This controller is supplied as the standard accessory, where the systems are matched with two outdoor units and more. Benefits of this controller include part loading of system capacity. In additional, the sequential controller can be installed at a distance of 1km away from the main controller.
OPTIONAL ACCESSORIES
(i) Soft Starter
(ii) Hot-Gas Bypass
(iii) Condenser Coil Grille
(iv) Copper Fin or Hydrophilic Fin for condenser coil
(v) Epoxy or Heresite Coating Fin for condenser coil
D.O.L. STARTER
Direct on line (DOL) starter as standard.
