  1. Leader in Ultrasonic Humidification

  2. HUMIDIFIRST’S HISTORY Designing and prototyping of Ultrasonic Humidifiers begins in 1992 in Harrisburg, PA First patent applied for in 1993 Shipped first equipment in 1994 to Boeing Co. Second patent applied for in 1994 Manufacturing begins in Burlington, NC in 1994 All manufacturing and R&D moved to Boynton Beach, FL in 2000

  3. Data Room Humidification

  4. ASHRAE Sets the Standards for the Recommended Data Room Operating Environment -Temperature -Humidity Reason? -To Reduce the Risk of ESD (Electrostatic Discharge) -ESD can damage electrical equipment -ESD can cause errors in operation & readings

  5. ASHRAE 2004 Recommended Data Room Operating Environment -Temperature = Low End at 68º F (20º C) High End at 77º F (25º C) -Humidity = Low End at 40% RH High End at 55% RH

  6. 2004 ASHRAE Psychrometric Chart

  7. 68F 40%RH 77F 55%RH

  8. ASHRAE 2008 Recommended Data Room Operating Environment -Temperature = Low End at 64.4º F (18º C) not 68F High End at 80.6º F (27º C) not 77F -Humidity = Low End “Dew Point” 41.9º F DP (5.5º C) High End “Dew Point” 59º F DP (15º C) But < 60% RH

  9. Why Use Dew Point for Moisture Control? • Studies show ESD is function of: -“Absolute Humidity” in Air, Not “Relative Humidity” of Air

  10. 2008 ASHRAE Psychrometric Chart High End Temperature is increased by 3.6º F Low End RH is decreased to < 30% RH at 80º F

  11. 68F 77F 64.4F to 80.6F at 41.9DP to 59DP

  12. Result ? ENERGY SAVINGS! Data Rooms can operate at: - Higher Temperatures - Lower RH Levels This Encourages Economizer Cooling

  13. How To Humidify Data Centers ? 1. Central Humidification -AHU -Ductwork 2. In-Room Humidification -In-CRAC -Wall Mount -Free-Standing

  14. Central HumidificationAHU Mounted

  15. Central HumidificationDuct Mounted

  16. Problems with Central Humidifiers: • Economizer Means Outside Air -Cold Air -Wetting Risk -Control Issues -Location of Humidifier: -Harder to Service -Difficult to Monitor • Direct Injection Steam- chemicals in air from boiler (needs heat exchanger—adds cost) 3. If Humidifier Must be Outside Data Room, Corridor/Gallery is Preferable

  17. Corridor/Gallery

  18. In-Room Humidifiers • In-CRAC Installation

  19. CRAC Installation Photos

  20. Problems with CRAC Humidifiers -Cold Air -Short Area for Evaporation

  21. In-Room Humidifiers • Wall Mounted • Free Standing

  26. Benefits of In-Room Humidification • Direct Room Introduction of Moisture a) Higher Output Capacity • Better Control a) Sense Room Moisture without Concern of High-Limit Saturation b) More Accurate. Particularly with Individual Sensors • Easier to Service • Safety Overflow Control by Sensor and Drain Piping

  27. Mist-Free Series Drain and Safety Overflow Ready
