LL Series
|
AAON LL Series Chillers and Packaged Outdoor Mechanical Rooms are engineered to be energy efficient, easily serviceable and to reduce field installation time. Standard construction for the LL Series is sound attenuating double wall rigid polyurethane foam insulated panel construction with walk-in compressor, control and water system service vestibules. Features and options available on the LL Series include factory installed boilers and factory designed and integrated chiller and boiler water system pumping packages.

Evaporative-Cooled Condenser LL Series Chiller
or Packaged Outdoor Mechanical Room |
| |
| |
| Applications |
| • |
Air-cooled or evaporative-cooled condenser chiller from 35 to 540 tons for comfort or process cooling. |
| • |
Packaged outdoor mechanical room with chillers from 35-540 tons and boilers from 500-6,000 MBtu/h. |
| • |
Packaged outdoor mechanical room is ideal for building retrofits, equipment expansion, system redundancy or temporary chilled water applications. |
| • |
Air-source, water-source or geothermal heat pump chiller configurations allow for energy efficient heating and cooling. |
| • |
Waterside economizer configuration is available for ultra high efficiencies at part load. |
| • |
Cooling operation in low ambient conditions is available with variable speed condenser fan and flooded condenser options. |
| • |
Units are available with factory designed and integrated primary and primary/secondary pumping packages with either constant or variable flow. |
| |
| |
| |
| Construction |
| • |
Double wall rigid polyurethane foam insulated cabinet construction has a thermal resistance of R-13 or greater, provides structural integrity and attenuates radiated sound. |
| • |
Lighted, walk-in vestibule allows maximum accessibility for service and maintenance of compressors, controls and water system. Control vestibule can be independently heated and/or cooled for comfort while periodic maintenance is performed on the unit. |
| • |
Hinged access doors are provided in areas subject to scheduled maintenance. Walk-in doors are constructed with stainless steel piano hinges, perimeter gaskets and zinc cast lockable handles. Doors operate from a single point and open from the outside of the cabinet. |
| • |
Designed for outdoor operation, the LL Series includes corrosion resistant exterior polyurethane paint which exceeds a 2,500 hour salt-spray test. |
| • |
Scroll compressors are installed on structural decks and rubber isolation mounted for quiet and efficient operation. |
| • |
Shell and tube evaporators are factory installed and insulated. |
| • |
Polymer e-coated air-cooled condenser coils can be specified to extend the life of the coils and protect them in corrosive environments. |

Packaged Outdoor Mechanical Room contains
Evaporator Barrel, Piping and Pumps |
| |
| | |
|
| Pumping Packages |
| • |
Pump and water piping systems can be factory installed in the LL Series. This saves valuable interior building space by eliminating pumps in the indoor mechanical room. |
| • |
LL Series units are available with factory designed and integrated primary or primary/secondary pumping with either constant or variable flow. |
| • |
All pumping packages include a factory installed in-line air separator, strainer, pump and combination valve (isolation, check, and flow balancing) in the water system. Victaulic piping and fittings are furnished as standard throughout. |
| • |
The LL Series can include dualArm and redundant pumps for system standby and parallel pumping systems. |
| |
| |
| |
| Features and Options |
| • |
Magnetic bearing R-134a Turbocor centrifugal compressor option provides load matching cooling capabilities, with quiet energy efficient operation, and the oil free design is highly reliable. |
| • |
Factory installed AAON evaporative-cooled condenser, with air-cooled de-superheater and variable frequency drive controlled fans, can be 20-40% more energy efficient than a comparable air-cooled condenser, can use 22-100% less water than a conventional evaporative-cooled condenser, and require 22%- 100% less chemical usage than a conventional evaporative-cooled condenser. |
| • |
Interior of evaporative-cooled condenser is constructed of 304 stainless steel and other non-corrosive materials. De-superheater coils include polymer e-coating for corrosion protection. |
| • |
Factory installed, microprocessor controlled, three chemical, water treatment system is standard with an evaporative-cooled condenser saving installation and maintenance time and money. |
| • |
Air-cooled condensers with variable speed condenser fans increase unit efficiency at part load, allow low ambient operation and reduce sound levels. |
| • |
Flooded condenser low ambient head pressure control on one or all refrigeration circuits are available for mechanical cooling during decreased ambient temperatures. |
| • |
Optional factory installed compressor isolation valves and water system thermometers and pressure gauges save installation and service time at the job site. |
| • |
Factory installed option boxes increase unit space for field installed components or for increased interior working area. |
| • |
Diaphragm expansion/compression tanks can be pre-engineered and factory installed. |
| • |
Gas train is UL/FM/CSD-1 compliant |
| • |
Boilers utilize variable frequency drives and air-fuel ratio valves to fully modulate burners between 10 and 100%. Burner modulation provides continuous demand matching of fuel and air rates, stable leaving water temperature, high boiler efficiency and a reduction in the weighted average flue-gas temperature. |
| • |
Boilers are a minimum 88% thermal efficient. |
| • |
Boiler combustion fan comes equipped with a replaceable combustion air filter which is 99% efficient to one micron. |
| |
| |
| |
| Controls |
| • |
Microprocessor controls are compatible with BACnet®, Modbus®, Johnson N2™ and LonTalk® protocols. |
| • |
Microprocessor controller cycles boilers to maintain the leaving water temperature to within 3°F of setpoint |
| • |
Labeled electrical components and color-coded wiring match the unit specific color-coded wiring diagram which is laminated and permanently affixed inside the control compartment. |
| • |
Run test report, color-coded wiring diagram, and Installation, Operation and Maintenance manual with startup form is included in control access compartment of every unit. |
