Angle:
This chart illustrates that the WattRod can be operated even against gravity (negative angles) due to the unique
design of the wick structure. Operation is most efficient near the horizontal, however, and we recommend horizontal
installation.

Delta-T:
The WattRod has enormous heat-transporting potential, moving large quantities of energy through a small aperture.
With proper attachment, a 150-Watt load will operate at only 13º C above the condenser temperature.

Temperature:
The temperature of the evaporator-end defines the operating temperature of the WattRod. The WattRod actually
operates most effectively at 150º C, as shown. This is due to equilibrium conditions of the 'steam-pressure' within the
evacuated tube.
