FACTORY OPTIONS AND/OR ACCESSORIES Economizer (dry-bulb or enthalpy) Power Exhaust with Barometric Relief Economizers save money. They bring in fresh, outside air for ventilation; and provide cool, outside air to cool your building. This is the preferred method of low- ambient cooling. When coupled to CO2 sensors, economizers can provide even more savings by coupling the ventilation air to only that amount required. Superior internal building pressure control. This field- installed accessory may eliminate the need for costly, external pressure control fans. Economizers are available, installed...

FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Optional Humidi- MiZer Adaptive Dehumidification System (cont.) once set up, the VFD will automatically adjust the speed between the cooling stage operations. The WeatherMaster 48HC04- 14 rooftop coupled with the Humidi- MiZer system is capable of operating in normal design cooling mode, subcooling mode, and hot gas reheat mode. Normal design cooling mode is when the unit will operate under its normal sequence of operation by cycling compressors to maintain comfort conditions. *Data based on .10 ($/kWh) in an office application utilizing Carrier’s HAP...

FACTORY OPTIONS AND/OR ACCESSORIES (cont.) Optional Stainless Steel Heat Exchanger The stainless steel heat exchanger option provides the tubular heat exchanger be made out of a minimum 20 gauge type 409 stainless steel for applications where the mixed air to the heat exchanger is expected to drop below 45_F (7_C). Stainless steel may be specified on applications where the presence of airborne contaminants require its use (applications such as paper mills) or in area with very high outdoor humidity that may result in severe condensation in the heat exchanger during cooling operation. Flue Discharge...
