Product Description

ROOFTOP AIR CONDITIONING UNITS
Reliable comfort comes from reliable technology

 

BENEFITS

COMPACT DESIGN
The compact design gives an aesthetic and neat appearance when installed in line of sight. Compact size benefits transport, handling and positioning on site, simplified and cheaper than traditional units.

RELIABILITY
All products are rigorously factory tested to ensure the top arrived condition in site. The strict testing procedure includes rain test, shipping test, shake and drop test, rigging test, coil leak test, and the whole unit running test. All units are fully factory tested; plug and play for the easier installation in site by reducing any unnecessary costs. This is one of the Amrta's rigorous requirements of responsibility to customers to make sure the reliability of our products.

DURABILITY
Cabinets are constructed from galvanized steel with polyester powder coated for all weather protection. The outdoor air coils' aluminum fins could be epoxy coated for extra protection in corrosive environments, for example the salt laden sea air. External fasteners are made by stainless steel or galvanized steel as well as the corrosion resistant drain trays. 10 years anti-corrosion warranty is guaranteed.

ECONOMY
2-4 stages operation compressors are progressively switched on only as they are needed. This has the added advantage of lowering start-up current. Especially, economizer such as free cooling or heat recovery option helps to reduce the operating costs.

FLEXIBILITY
The dedicated vertical or horizontal supply/return configurations allow easy utilization on replacement jobs or new construction applications. Unit may be configured to precisely match the building requirements through the use of factory-installed options such as: integrated economizer, power air exhaust, high static pressure indoor fan and coil protection options.

EASY MAINTENANCE
The condenser and evaporator fan motor bearings are permanently lubricated with long life, and no annual maintenance need, adding greater reliability to the unit. The service access ports are protected, externally mounted, reusable, provided on both the high and low lines for ease of evacuating and charging the system. A large, single panel covers the electrical controls makes servicing easy. The blower compartment has a large panel which will allow the blower fan assembly to slide-out for ease of maintenance and trouble shooting.

SAFETY
The refrigeration system operates with a number of protection means: dry-filter, discharge temperature protector, liquid sight glass, HP and LP switches, phase sequence relay, circuit breaker and contactor etc.

LOW NOISE
Electrical and compressor section are insulated to reduce noise. The upward discharge of condensing fans carries away effectively the operating noise. And all compressors and fans are mounted on rubber anti-vibration supports for quiet design.

FEATURES

 

CASING
Panels are made by galvanized steel with polyester powder paint for excellent finish, weatherability and corrosion resistance. The pre-treated galvanized steel provides a better paint to steel bond, which resists corrosion and rust creep. Special primer formulas and matted-textured finish insure less fading when exposed to sunlight. The stainless steel screws are used throughout to further reduce possibility of rusting.

EXTERNAL THERMAL EXPANSION VALVE
Independent thermal expansion valve with external balance offers better refrigerant control and wider load condition.

CENTRIFUGAL FAN
Belt-drive centrifugal fans of air supply section are designed with forward-curved blades, ac asynchronous induction motors and multi-speed control for maximum efficiency and adequate airflow distribution. Motors are highly efficient inducted, with class B insulation to ensure quiet operation and smooth performance. VFD drive modulating, upgrade plug fan and EC plug fan are possible as option.

CONDENSER FAN
Condenser fans are direct-driven axial type, air-discharged vertically with a low level noise, which use aluminum blades riveted with corrosion resistant steel spider bracket to allow a statically balanced and smooth operation. All condenser fans are protected by wire guards, and fans motors are secured by permanently lubricated bearings against overload conditions. The condenser fan with optional EC motor.
 

COMPRESSOR
The units use high efficiency, hermetically sealed, compressors, oil return lubrication and rubber vibration damper. The thermal overload cut-out, phase sequence relay and crankcase heater are integrated as the security protection to enhance reliability and performance.

DEFROST
Dynamic and alternate defrost function is provided to heat pump rooftop units to ensure efficient operation in winter. Units start defrost cycle when the ambient temperature is below a set temperature and repeat the defrost cycles periodically. The defrost cycle is automatically controlled by outdoor sensor. The timing and duration of defrost can be set up by a combination of timing functions on the control device.

FILTER
5 mm thickness washable Nylon filter is used as standard feature. G4 filter is available optionally.

ELECTRIC COMPONENTS
•    Direct-on-line starting contactor for the compressors and condenser fan motor.
•    Internal thermal protector for compressor and fan motor.
•    Anti-recycling protection (time delay) for compressors through microprocessor.
•    Crankcase heater for compressor.
