ADDISON™ SPECIALTY OPTIONS

100% Outside Air Treatment

Fresh air adds to a comfortable indoor environment by improving indoor air quality and ventilation. Several ADDISON™ products offer 100% outside air capability.


Dehumidification

• 6 row DX evaporator coils for increased cooling and dehumidification capability.

• Hot gas reheat (staged or modulating), located downstream of the evaporator, for precise supply air dry bulb temperature.

• Head pressure control system with a variable speed motor-driven fan is controlled from refrigerant pressure rather than ambient temperature to reflect the operating conditions in the unit.

• Liquid sub-cooling for increased capacity/efficiency and lower dew point.

• Addison has a specialized combination of hot gas reheat and liquid subcooling. This option helps increase equipment capacity, while helping to reduce electrical usage, which can result in significant savings and increased efficiency. A one-row subcooling coil may be factory-installed; adding up to 35° F (1.7° C) of subcooling. Compressor capacity increases approximately 1% for every 2° F (-17° C) of subcooling.



Digital Scroll Compressor

The digital scroll compressor will help to greatly improve unit performance at part load conditions, thus allowing the unit to match the required load. Additionally, by reducing the on and off cycling of the compressor, it will help to greatly reduce the wear and tear and increase the compressor life.


Energy Savings

Packaged units have high efficiency scroll compressors, job specific fan sizing and large surface heat transfer components to help maximize energy efficiencies. Energy recovery wheels are also available to transfer heat and moisture between the incoming fresh air and the outgoing exhaust air, thereby using less energy to provide more optimal temperature and humidity levels.


Controls-Automated Logic Controls (ALC)

• Remote bulb entering and leaving air thermostats and pressure switches.

• Wall thermostat control.

• Addison will also mount and wire controls supplied by others.


Filtration

• A multitude of filtration options are also available.


Coil Coatings for Harsh Environment Protection

•Corrosion-resistance and microbial coating is approved up to 10,000 hours salt spray test (per ASTM B117 97). To help facilitate an even coverage on coils, they are coated prior to assembly, providing a high level of protection.

•Cabinet and components’ coatings for harsh environment protection

•Interior and exterior of the cabinet are coated to protect units when exposed to moderate to aggressive corrosive atmospheres. Coating may also be applied to tubing, compressors, blowers and other internal components for up to 10,000 hours salt spray test protection.


Copper Fins

Evaporators and air-cooled condensers can be furnished with copper fins.
