Performance based on 70° Entering Air Temperature (E.A.T.) and 5# Steam.

For other steam pressures - see chart on reverse side.
Berner recommends that maximum Leaving Air Temperature (L.A.T.) never exceed 120° F
Berner recommends coils should be supplied by a solenoid valve that energizes only when air curtain is on.
