Notes:
gpm = gallons per minute, lpm = liters per minute,
H/L = head loss, ft = head loss in feet,
m = head loss in meters.
Maximum temperature rise is 35°F (19°C), as shown.
Head loss is for boiler’s heat exchanger only.
N/R = not recommended.

IMPORTANT NOTES:
Different glycol products
may provide varying degrees of protection.
Glycol products must be maintained properly in a
heating system, or they may become ineffective.
Consult the glycol specifications, or the glycol
manufacturer, for information about specific
products, maintenance of solutions, and set up
according to your particular conditions. Never use
ethylene
glycol (automotive antifreeze).
