Air-Cooled Condensers
Capacities to 10 Tons
9AB Air-Cooled Condensers available in nominal capacities of 5, 7% and 10 tons are designed for verti cal installations with horizontal air flow. They may be located in any area having unobstructed air circula tion; the low silhouette permits installation in varied ground or roof locations. Each unit consists of a direct drive motor (or motors), fan (or fans), fan guards, motor mounts, condenser coil with integral subcooling circuit, wind deflector, and electrical junction box. Weather Armor* enclosures (which are also provided for 09DC016) have a baked enamel finish which pro vides maximum weather protection.
Capacities 15 Tons and Over
09DC Air-Cooled Condensers are available in 15-, 20-, 25-, 30and 40-ton sizes. The 25-, 30and 40-ton sizes are designed for use in multiples to give capacities of 50, 60 and 80 tons. Each size has three direct drive fans, three motors and motor mounts, three guards, a junction box, and a condenser coil with integral sub cooling circuit. The 20-, 25-, 30and 40-ton units, all using vertical air flow, may have 2 or 3 circuits, each with an integral subcooling circuit. Each circuit may be used as a separate condenser for a single system. Double-weight, hot dipped, galvanized steel enclosures give maximum protection.
•Multiple Fans and Motors provide inexpensive, re liable system control in intermediate seasons. Standby protection is provided in case one fan motor fails.
•Subcooling permits greater liquid lift in vertical risers without liquid flashing. Special coil circuiting cools liquid refrigerant below the saturated condensing temperature, extending system capacity without in creasing motor horsepower.
•Direct Drive Fans require no tensioning device or pulleys. Alignment problems, belt maintenance, and friction loss are eliminated.
•Three Types of Head Pressure Control (Accessory) are available to maintain a refrigeration load by hold-
ing a minimum head pressure and reducing condenser capacity at low outdoor temperatures.
1.Motormaster Electronic Control (9AB6, 8, 12 and 09DC016, single-phase) modulates condenser fan motor speed from zero to full rpm.
2.Fan Cycling Control cycles one fan (9AB8, 12) or
two fans (09DC) for control during intermediate seasons.
3. Head Pressure Control Damper (09DC024, 084), mounted below unit at the uncontrolled fan section, further reduces capacity.
• Winter Start Control — Optional package permits start-up of compressor regardless of low temperatures.
