Health

• Conditions that cause poor Indoor Air Quality
• Chemicals that are natural and manufactured
• Biological pollutants
• By-products of human and animal metabolism

• Biological growth
• Mold
• Mildew
• Bacteria
• Virus
• Dust mites

• Chemical pollution
• Radon gas
• Out-gassing of chemicals
• Pesticides and cleaning solutions
• Smoking

Regulations

• ASHRAE 62.2
• New code requiring fresh air for low-rise
  residential buildings
• Improves indoor air quality (IAQ) by diluting
  chemical pollution
• Requires a desiccant in humid climates

8
Litigation

• MOLD is the next ASBESTOS
• Schools
• Libraries
• Residential
• Hotels/Motels

9
Improved Technology

• Todays Energy Efficient Buildings
• High efficiency, but reduced ability to remove
  moisture
• Typically oversized with shorter run times,
  reducing moisture removal
• Better construction has homes much tighter

10
Desiccant Technology

• Use a heat source to heat the air to dry out the
  adsorbent material to continually remove moisture
• Two types of materials commonly used
• -desiccant liquid sprayed or cascaded into air
  stream
• -solid desiccant material impregnated into
  surface of rotating wheel

11
Desiccant Technology

• Gas-fired residential desiccant is the best
  solution
• Typical gas-fired residential desiccant will add
  200 to 300 therms of natural gas a year
• First new residential gas appliance to be
  introduced in decades

Market Growth

• Nearly half of the United States is a geographic
  target
• Residential
• Commercial
• Institutional
• Natural gas utilities can use desiccant to
• Increase market share
• Improve customer satisfaction and loyalty
• Maintain and improve customer retention
