Stulz DRH Standalone Humidification Systems

Stulz DRH Standalone Humidification Systems

STULZ Direct Room Ultrasonic Humidifier (DRH), designed for stand-alone room applications. DRH humidifiers are typically mounted on the perimeter wall serving mission critical applications and any environment where tight humidity control is required.

Description

Ultrasonic humidifiers for direct room humidification

For direct room humidification, STULZ offers units from the STULZ UltraSonic® BNB 1000 to BNB 8000 model series.

All major components of these units are made from stainless steel or high-grade plastic. A fan integrated in the housing distributes the steam, which is generated in the water bath, around the room.

These units are employed, for example, for the humidification of production rooms, computer rooms, storage facilities, printing plants, museums, restoration workshops, theatres and many other areas in which optimum humidity is essential for production, storage or the indoor climate.

Tried and tested controller components ensure that the desired room humidity is precisely maintained.USM/USS-Controller

Features & Benefits of Ultrasonic Humidification

Design

  • Multiple piezoelectric transducers immersed in a water bed impart high frequency oscillation
  • Alternating pressure and vacuum causes cavitation and production of very fine water mist
  • Average 1 micron diameter water droplets evaporate quickly in a room or moving air stream
  • All wetted surfaces are constructed of non-corrosive materials including plastic and stainless steel
  • Distributed power to the piezoelectric transducers is 48 Volts, AC or DC depending on application
  • Internal humidifier safeties include low and high water level switches and high temperature cutout

Performance

  • Adiabatic humidification process requires less than 10% of the energy required to boil water into steam
  • Additional benefit of evaporative cooling – improves efficiency of high sensible heat applications such as data centers
  • All specifications and selections include mixed bed deionization water treatment systems by Culligan
  • 100% of the demineralized water in the humidifier may be utilized and does not require a flush cycle
  • Extremely low operational expense equates to very short term Return on Investment (ROI)

Controls

  • STULZ Ultra-Series Proportional controls are engineered for single or multiple humidifier systems
  • Utilizes STULZ E² Microprocessor Controller for integrated operation of up to 16 humidifiers per zone
  • Ultra-Series control boxes enclose up to 8 power supplies each, providing power and control distribution
  • Proportional analog output from microprocessor converted to Pulse Width Modulation at humidifiers
  • Monitors and communicates various system functions and alarms including water quality via integrated control and/or optional BMS

Applications

  • Data Centers/Telecomm
  • Libraries/Museums
  • High Tech Manufacturing
  • Printing/Duplication
  • Food & Beverage
  • Agriculture/Tobacco
  • Health Care Facilities
  • Laboratories
  • Commercial Offices
