2. Features viii. Field Convertible Air Throw Std = Horizontal Throw Site Convertible = Down Throw Standard factory fitted is always horizontal supply/return. However, unit can be easily converted from horizontal to vertical (downward) air supply & return configuration by relocating the panels and supply air fan mounting.
3. Components Features Compressor Compressor used in A5RT-BR series Packaged Units are hermetically sealed scroll type. All the compressors are provided with an internal overload protection. Condenser 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 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 (NA549) is offered as standard, which has longer life span under corrosive environment. Evaporator : 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 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. Hydrophilic Gold Fin coating (NA549) is offered as standard, which has longer life span under corrosive environment.. Casing/ Structure The unit casing used in A5RT-BR series is made of zinc coated galvanized steel sheets. It is further coated with an electrostatic powder coat and then oven- baked for a tough and lasting weather resistant finish. Zinc plated screws are used throughout to further reduce possibility of unit rusting. Expansion device: Electronic Expansion Valve is being used to ensure accurate control of refrigerant flow. Refrigerant Circuit Each refrigerant circuit shall have independent electronic expansion devices, HP/LP switch and refrigerant line service pressure ports as standard factory installed. Evaporator Fan and Drive Blower is DWDI centrifugal, forward curved type. It is mechanically and dynamically balanced and being mounted on a rigid shaft in a self aligned bearing block. The motor is fitted with an adjustable V-belt drive, as standard. It has class B insulation and dripping water proof, IP22. Condenser Fan and Motor Fans are of propeller type, direct driven by weatherproof electrical induction motors. Condenser fan motor has class F insulation and splash-proof enclosure, IP44. Insulation: ALL possible areas of condensation to happen are insulated by PE, Polyethelene. Panel insulation is 10mm thickness while drain pan insulation is 5mm thickness.
4. Optional Features i. Economizer Economizer option is available as factory fitted. It is also designed to cater for horizontal or vertical down throw air supply/ return. ii. CO2 Sensor Field specified CO2 sensor can be easily plug on the control board’s dry contact, which is available on the Economizer Extension Board. iii. Auxiliary Heater Auxiliary heater connection point is available on the standard PCB for field supplied heater connection.
