Hi-Steam introduced the Turbo 484 Cobra, a form finisher shirt unit.  The overhead hood captures the heat rising from the buck as a shirt is being pressed and recirculates it, drastically reducing energy consumption.  They claim a 25% reduction.  Hi-Steam eliminated the yoke press on this model as well as the vacuum in the front clamp.  They explained to me that the vacuum lowered the buck temperature which has previously affected the press quality.
