Overview

• SAM-e basics
• Why SAM-e?
• Why insulate?
• SS air gap insulation
• R-Value
• New product updates

9
Why SAM-e?

• Short absorption distances are required
• Easy to install
• Lower cost easier to install than multiple
  LS distributors
• No maintenance required
• Can be used with atmospheric steam or pressure
  (boiler) steam
• Your AHU manufacturers like it!

10
Why Insulate? SAM-e Insulated Option

• Reduce condensate losses and increase efficiency
• 1075 BTU Liquid Water 1 lb Steam
• 8.35 lbs Steam 1 US Gallon Wasted Water
• 1 US Gallon Wasted Water Over 8000 BTU Wasted
  Energy

11
Why Insulate? SAM-e Insulated Option

• Air stream heat gain
• Low humidifier output
• Low system efficiency

12
Benefits of Insulation SAM-e Insulated Option

• Up to 70 condensate reduction
• 120F max surface temperature
• Reduce heat gain
• Improved efficiency

New White Paper

• R-value represents a materials ability to resist
  the transfer of heat
• Condensate losses dependent on a number of
  factors
• Air temperature, duct velocity, distributor
  configuration
• Have you seen an insulated distributor spec
  calling for
• R-value not less than 0.5
