DESCRIPTION
All 30RB060-390 units are packaged air-cooled liquid chillers that are factory wired, refrigerant piped, and
charged with R-410a refrigerant. Any 30RB units with the remote cooler option require field-installed piping,
controls, and must be field charged with additional refrigerant. Weatherproof construction and compact design
makes 30RB units ideal for rooftop or ground level installation. Upward discharge airflow minimizes directional
sound and dissipates heat away from surrounding areas.
FEATURES
Compression
• Hermetic scroll compressors are maintenance free and pro-
tected by an auto-adaptive control that minimizes compressor
wear.
• External and internal compressor motor protection.
• Complete oil charge.
Refrigerant Circuit
• Unit sizes 060-190 have dual independent refrigerant circuits.
Unit sizes 210-300 have three independent refrigerant circuits.
Unit sizes 315-390 have four independent refrigerant circuits.
• Low and high side fusible plugs.
• Moisture indicating sight glass.
• Electronic expansion valve with integral sight glass.
• Filter drier, removable core. Optional non-removable core filter
drier is available for unit sizes 060-100.
• Discharge and liquid line service valves. An optional suction
service valve is available.
• Complete operating refrigerant charge, except for remote
cooler option.
Air-Cooled Condenser
• Air-cooled condenser coils are constructed with aluminum
plate fins (copper fins optional) mechanically bonded to seam-
less copper tubes with an integral subcooling circuit.
• Specially designed 3-phase, direct-drive, condenser-fan motors,
permanently lubricated bearings.
• External and internal fan motor protection.
• Condenser fans are 9-blade, shrouded axial type, statically and
dynamically balanced, discharging air vertically.
Cooler
• Integral shell and tube cooler with
3
/
4
-in. (19 mm) closed cell
polyvinyl chloride foam insulation with a maximum waterside
pressure of 300 psig (2068 kPa).
Controls
• Microprocessor-based leaving water temperature control with
return water compensation.
• Loss of charge protection included.
• Automatic lead-lag circuit operation.
• Seven-day time schedule.
• Chilled water pump start/stop control and primary/stand-by
sequencing to ensure equal pump run time.
• Dual chiller control for parallel chiller applications without
additional hardware, modules, or control panels.
• Unoccupied low sound operation to limit condenser fan sound
during scheduled periods.
• Maintenance scheduling to signal maintenance activities for
pumps and strainers.
• Low chilled water flow protection is provided via an electronic
thermal dispersion flow switch.
• High-pressure switch.
• Intermediate season head pressure control.
• Microprocessor control includes keypad with diagnostic dis-
play with access to set points, time and date, system status
including % capacity, operating temperatures and pressures,
and alarm conditions.
• Periodic pump start to ensure pump seals are properly main-
tained during off-season.
Cabinet
• Cabinet constructed of galvanized steel, phosphatized zinc,
with electrostatically applied high solids, polyester baked
enamel finish with hinged access panels.
Hydronic Package Option
• Optional hydronic pump packages are available (unit sizes 060-
190) in single and dual pump arrangements with a maximum
waterside pressure of 150 psi (1034 kPa). A strainer, combina-
tion valve, and pressure taps are provided with the package.
