Capacity Notes
• Approximately 172 BTU’s are required to raise the
temperature of one pound of water from 40° to 212° F.
• An additional 970 BTU’s are required to change one
pound of water to water vapor.
• The ¾" rigid foil faced fiberglass insulation on all
surfaces of evaporating chamber increases unit efficiency
by approximately 2%.
• Another factor to consider is condensation steam loss
from hoses and tubes. Use the following steam loss
guidelines:
- vapor hose: 0.15 lbs/ft/hr
- insulated pipe: 0.05 lbs/ft/hr
- dispersion tubes: 0.50 lbs/ft/hr
