DUAL-TEC™ WALL-MOUNT™ Air Conditioners with -48VDC Blower Motor DC Voltage 100% Free Cooling Unit D28A/L to D60A/L 1-Stage Right & Left-Hand Control Panel The Bard DUAL-TEC™ Wall Mount™ Air Conditioners with -48VDC Blower Motor and DC Voltage Free Cooling Economizer are designed for maximum indoor cooling at the most efficient operating cost for year-round operation in the demanding equipment shelter environment. The DUAL-TEC™ units operate on both AC and -48VDC positive ground power under normal power supply conditions. If there is loss of AC power supply (shore and/ or back-up generator) the DUAL-TEC™ will continue to operate as free-cooling or ventilation system using the shelter’s DC power. The DUAL-TEC™ indoor blower and economizer operate from -48VDC and no inverter is required. The DUAL-TEC™ units will supply up to 100% of rated cooling airflow in free cooling mode with the ability to exhaust the same amount through the unit itself without any additional relief openings in the shelter.

Field Power Wire Size
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest version), Article 310 for power conductor sizing. Caution: When more than one field power circuit is run through one conduit, the conductors must be derated. Pay special attention to note 8 of Table 310 regarding Ampacity Adjustment Factors when more than three (3) current carrying conductors are in a raceway. Maximum size of the time delay fuse or HACR type circuit breaker for protection of field wiring conductors. Based on 75C copper wire. All wiring must conform to the National Electrical Code and all local codes. IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses & conductor wires in accordance with the National Electrical Code & all local codes.
