Herrdraulic HP


The Herrdraulic™ High-Pressure Humidification System provides adiabatic humidification solutions for both air handler and duct applications. The highlight of the Herrdraulic system is its energy efficiency. By utilizing a positive displacement pump to generate fine droplets in combination with its adiabatic evaporative process, the Herrdraulic uses roughly 1/10 the energy of an air/water atomization system, 1/80 the energy of a fossil fuel fired boiler, and 1/350 the energy of electric steam humidifier! Because it is an adiabatic process, approximately 1,070 BTU’s of heat energy is removed from the air to evaporate each pound of water, making it ideal for processes that have high internal heat loads. Systems in excess of 3000 pounds per hour are available.
