LN Series

Chillers and Outdoor Mechanical Rooms with VFD Controlled Variable Speed Scroll Compressors, Microchannel Condenser Coils, Double Wall Rigid Polyurethane Foam Injected Panel Construction, and Sound Attenuating Service Compartments with Lockable Hinged Access Doors. Options include Brazed Plate or Shell and Tube Evaporators, Factory Installed Pumping Packages, and VFD Controlled Variable Speed Condenser Fans. The LN Series can be matched with any AAON Chilled Water Handling Units.

Construction

The LN Series chiller has factory assembled and tested components, piping between pumps and the components, and wiring to accept a single-point electrical connection.
Designed for outdoor operation, the outdoor mechanical room includes a corrosion resistant paint that exceeds a 2,500 hour salt-spray test.
Paint can be specified in a variety of colors to enhance the aesthetics of visible units.
Compressors and controls are accessed through service compartments that shield from weather and outdoor elements.
Double wall cabinets utilize thermal breaks and closed-cell polyurethane in its rigid polyurethane foam panels to increase thermal resistance, reinforce structural integrity, and attenuate radiated sound.
Scroll compressors are installed on structural decks and rubber isolation mounted for quiet and efficient operation.
Hinged access doors are provided in areas subject to scheduled maintenance. Doors are constructed with stainless steel piano hinges, perimeter gaskets and zinc cast lockable handles.

Features and Options

Variable capacity R-410A scroll compressors and VFD controlled variable speed R-410A scroll compressors are available for load matching cooling capabilities and increased part load efficiency.
Insulated shell and tube or brazed plate evaporators are factory installed in each unit.
Variable speed condenser fans are available to increase unit efficiency at part-load and low ambient conditions, increase operating temperature range, and reduce sound levels.
Low ambient control on one or all refrigeration circuits are available for mechanical cooling during decreased ambient temperatures.
Glycol chillers for refrigeration applications.
Polymer e-coated condenser coils can be specified to extend the life of the coils and protect them in corrosive environments.
Optional factory installed compressor isolation valves, water system thermometers, and pressure gauges save installation time at the job site.

Controls

Microprocessor controls are compatible with BACnet®, Modbus®, Johnson N2™, and LonTalk® protocols.
Color-coded wiring matches unit specific color-coded wiring diagram which is laminated and permanently affixed inside the control compartment.
Control components are labeled to simplify service and scheduled maintenance.
Factory run test and inspection reports are included in the documentation compartment affixed to the interior of the control compartment access door.
