Dehumidification and Ventilation Operation

Dehumidification (Air-to-Air or Water-to-Air Systems)

Many Bard systems, typically those used in schools or other commercial applications, have a dedicated
dehumidification capability by having a special additional refrigeration circuit (factory-installed option only) in
addition to the basic system. These special systems, sometimes also referred to as hot gas reheat, are designed to
control humidity on demand from a humidity controller much the same as the basic cooling and/or heating system
is controlled by a wall thermostat. Consult your installer and/or service company to determine if your installation has
any of these devices and for any instructions or maintenance requirements you should be aware of as the user.

Ventilation Options (Air-to-Air or Water-to-Air Systems)

All Bard systems are available with factory-installed vent options. Most units can have ventilation field installed after
unit installation.
Ventilation has multiple purposes:
• Outside air intake for occupied structures
• Positive pressurization
• Energy savings when outdoor air can be used for cooling
• Agricultural use of bringing in outdoor air and exhausting room air
• Equipment and electronics ventilation
Review product specifications and manuals for more details regarding available ventilation options and features.
