2 AIR-COOLED CONDENSING UNITS GENERAL DESCRIPTION The 6ACCS & 6ACCR series with new features is suitable for hotel, office, schools, hospitals, factory and supermarket applications. The low noise and compact series are completely leak tested, evacuated, dehydrated and charged with dry nitrogen to maintain system dryness prior to field piping connections. Scroll Compressor(s) (6ACCS Series) Reliability No contact scroll design that minimizes friction, increases volumetric efficiency and reduces vibration, thus longer service life. Suction gas cooled motor. Low Power Consumption: High EER. No crankcase heater required. Modular Concept (250 to 800) Ease of hoisting and installation: Modular condensing units to match single indoor evaporator-blower unit, provide ease of hoisting and flexibility of installation of condensing units in constraint space. Tandem Compressor (6ACCS 890B to 1520B) For condensing units, each with 6 or 8 compressors, every two compressors is connected in tandem, to reduce refrigerant circuits to 3 or 4 and thus reduce the cost of labor and materials for field piping connection works. Multiple Large Capacity Reciprocating Compressor (6ACCR Series) Reduce the cost of labor and material for field piping works. Reduce the number of electrical starters. Class F Insulation Condenser Fan Motor (6ACCR Series & 6ACCS Series) Extra safety margin and longer motor life even in extreme operating conditions. IP 55 construction ensure extra motor protection Low motor speed at 1140 rpm ensures quiet condenser fan operation. Multiple Compressor (6ACCR Series and 250B to 1520B Series) By cycling off compressor(s) operation to match building load, no energy is being wasted when room load requires lesser cooling capacity. No total shut down when servicing or repairing a faulty compressor. Efficient Condenser Coil Staggered row of 3/8 OD inner groove tubes with 25 to 30% more surface area guarantee better heat transfer. Mechanically expanded into die-formed corrugated aluminum fins. Integral subcooling circuit to maximize efficiency. Leak and pressure tested to 450 psig. Fully Leak Tested Refrigerant Circuit Leak and pressure tested at 450 psig. Pressure ports are provided on the discharge, liquid and suction line. Evacuated, dehydrated and pressurized with dry nitrogen for storage and shipping purpose. Safety Control High-low pressure cutout to protect compressor from high discharge pressure and system leakage. Casing Constructed from heavy gauge galvanized steel. Panels are painted with epoxy-acrylic electro deposition paint for excellent finish, weatherability and corrosion resistance.

3 DUCTED EVAPORATOR BLOWER UNITS GENERAL DESCRIPTION The ducted evaporator-blower units; each consist of an evaporator coil, a centrifugal forward-curved blower fan complete with drive package and filters and enclosed in a single fibreglass insulated rigid steel cabinetry; are completely factory packaged to provide greater flexibility to the building owners, consultants, architects and installers. These flexibility includes; A wide range of model sizes covering cooling capacities from 73 to 1360 MBH; and each model size also has a wide band of air-flow rates (cfms) covering a wide band of static pressure to meet almost any system demands. Except for 6HEB 81D and 6HEB 95D which are specially designed for ducted, ceiling application, all other sizes allow flexibility for either horizontal air discharge or vertical air discharge ducted connections. All units can be provided with left or right hand piping connections. Except for 6HEB 81D and 6HEB 95D, which are direct driven, all units can also be left or right hand motor location to ease installation at site. This must be specified at the time of order entry to factory. Efficient Evaporator Coil Independent thermal expansion valve with external equalizer for better refrigerant control and wider load condition. Leak and pressure tested to 450 psig Evacuated, dehydrated and charged with dry nitrogen. Drive Package and Blowers (6HEB 110D to 6EB 1520D) Belt driven drive package offers flexibility on various air flow rate and various static pressure applications. Single large diameter double inlet double width blowers (AMCA certified) reduce the noise level and eliminates the need for common transition and eliminates air unbalance. Casing Constructed of electro galvanized steel sheet and insulated with 1/2 thick x 1 1/2 lb per cu.ft linacoustic fiberglass. Aesthetically coated with epoxy-acrylic electro deposition paint to provide excellent finish, weatherability and corrosion resistance. Removable panels on the left and right hand side of the unit to provide access to critical parts and components. Filters Side loading 1 thick filters - from both sides-thus eliminates unnecessary duct opening at site. OPTIONAL ACCESSORIES FEATURES Factory wired starters - DOL for compressors and fan motors. - Auto-transformer for compressors. Suction stop valve(s), discharge stop valve(s) and liquid stop valve(s). Internal spring vibration isolators for blower fan and drive assembly in EB units. Fan staging of multiple fans for head pressure control. Thermostat Hydrophilic fins, copper or tinned coated copper fins for better corrosion resistance. Axial fan for ducted air discharge. Liquid line filter drier and sight glass Hot gas by pass for low load and low ambient conditions. Decorative discharge plenum Hot water heating coils Electric heaters R407C refrigerant instead of R22.
