Vulcan-Hart C24EA3 DLX manual How steam becomes PowerSteam, Staged fi lling keeps the boil boiling

How steam becomes PowerSteam.

PowerSteam combines heat and speed to produce a more powerful cooking steam. The steam gets its extra “power” through a unique two-part process: superheating and staged fi lling.

Superheated steam increases cooking energy by 10%.

Steam at sea level is hot. But superheated steam is hotter. Before steam reaches the cooking compartment, it’s reheated with either fl ue gas or a secondary electric heater. Here the steam temperature rises from its normal sea level temperature of 212°F to its PowerSteam temperature of 235°F. By raising the steam temperature, the cooking energy is increased by at least 10%. Vulcan is the fi rst company to use superheated steam for steam cooking. The process is patent pending.

Staged fi lling keeps the boil boiling.

Staged fi lling is the process of slowly applying replenishment water to the boiler/generator after it has initially fi lled. In Vulcan’s C24GA6 PowerSteam model, for example, it takes three minutes to

fi ll its large-capacity (12-gallon) generator. Once the generator is fi lled, “slow fi ll valve” meters add a small amount of replenishment water during cooking. The benefi t of the slow fi ll valve is that the boil is not “killed.” During high-volume steam
