DC FREE COOLING UNIT SYSTEM (DC-FCU)
The Bard DC Free Cooling Unit system is composed of two (2) D-Series DUAL-TEC™ wall-mounted air conditioners
matched with one (1) Bard-Link
market, can provide outdoor air cooling during power loss situations through the use of onsite -48VDC positive
ground battery banks.
NOTE: The Bard-Link
PLC lead/lag controller and the D-Series wall-mount units are designed specifically to
TM
work together. The PLC controller cannot run other Bard models or other brands of systems, nor can other
controllers or thermostats run the D-Series wall-mount units. They are a complete system, and must be used
together.
WALL-MOUNT AIR CONDITIONER UNITS
The D-Series units operate on both VAC and VDC power under normal power supply conditions. If there is loss of VAC
power supply (shore and/or back-up generator) the unit will continue to operate as free cooling or ventilation system
using the shelter's VDC power. The indoor blower and free cooling unit operate from -48VDC and no inverter is required.
The units will supply 100% of rated cooling airflow in free cooling mode with ability to exhaust the same amount
through the unit itself without any additional relief openings in the shelter.
Each of these units are fully charged with refrigerant and have auxilliary heat installed.
