Ultra-sorb® XV steam dispersion panel for pressurized steam applications Short absorption and energy savings with pressurized condensate return The Ultra-sorb XV from DRI-STEEM® Corporation is the most energy-efficient steam dispersion panel in the commercial and industrial humidification market. Ultra-sorb XV combines a proven energy-saving breakthrough with a brilliant condensate return strategy. First, the high-efficiency tubes are insulated with PVDF to reduce wasted energy, airstream heat gain, and condensate production by up to 85%. Second, an integral heat exchanger vaporizes dispersion-generated condensate and returns pressurized condensate to the return main without additional pumps, valves, or controls.
