Heating Power: The GC Racer can more than double the heating power of the GC. Power can be measured in Volt-Amps (VA). An Agilent GC oven runs on 120V, 13 amp = 1560VA. The GC Racer supplies 1800 VA (120V X 15 amp) additional power for a total of 3360VA heating power. By contrast a “fast-ramp” oven (240 V X 10 amp) = 2400VA.
