Ultrasonic Humidification
Ultrasonic humidification is the the leading
technology for both energy efficient
production of humidification
vapour and efficient absorption of the vapour
into the air stream.
Principles of Ultrasonic Humidification
The ultrasonic transducer is a piezo-electric
crystal immersed in water where it converts
high frequency electronic signals into high
frequency mechanical oscillations.
The water tries to follow the high-frequency
oscillating movement of the crystal (1.65 MHz)
but cannot. As a result, a momentary vacuum
is created on the negative oscillation of the
crystal wherein the water cavitates into vapor.
Then, on the positive oscillation, high
pressure waves force the cavitated water
through the surface of the water as a very
fine mist (about 1 micron), which is easily
absorbed into the air flow.
Energy Efficiency and Droplet Size
Ultrasonic humidifiers use approximately
25 watts of power to produce a pound of steam with one a droplet size (1) micron in diameter. An equivalent steam system would use 350 watts to make the same pound with the same droplets. |

Mist Pac
Available in four sizes 5#, 15# 18# & 25#
per hour, the Mist Pac ultrasonic humidifiers
from Humidifirst® are designed for
stand alone use. Each unit is built to
achieve simplicity of installation and
maintenance. The Mist Pac Series
uses standard 120V power and has
quick-connect fittings for water and
electricity. The humidistat is prewired
to the control panel. Optional
ULTRA-PULSETM and HC-301
MICRO-PROCESSOR systems offer
pulsating output for tighter RH
control.
Mist Free
Humidifirst's Patented Mist-Free (MF)
humidifiers are uniquely that ... mist free!
Perfect for humidification needs where visible
mist is objectionable, such as small hospital
equipment rooms, computer rooms, office
areas and low ceiling printing rooms.
The Mist-Free series ultrasonic humidifiers
are available in 9 and 19 #/hr capacities.
Humidifirst® offers a choice of humidity controllers, ranging from a mechanical on/off humidistat to a state-of-the-art microprocessor with proportional control and modem interface.
The ultrasonic system is virtually maintenance-free. That's because the use of
treated water eliminates the build-up of
deposits on any part of the humidifier. With no
minerals and particles entering the system,
no scaling, plugged nozzles or clogs occur
in the system. Likewise, this greatly reduces
the need for servicing the equipment
since no cleaning is required. |

‘DT’ Units (Ductable to Air Handlers) available in
Single or Multiple Rack Mounted Units
The broadest line of duct mountable humidifier modules in the industry.
The DT-series output capacities range from 10 to 80 #/hr per humidifier module.
Unique adjustable discharge nozzles allow for operation in higher velocity airflow.
Factory racking of humidifier modules is available. Eight different software programs
are available to optimize precision control of humidity. |
Liebert Retrofit Kit
The Humidifirst Retro-fit kit is custom designed for your existing Liebert computer room air conditioner - for Liebert 20 ton to 30 ton downflow units. Designed to replace infra red humidification systems that use 450 watts to make a pound of steam. Paybacks are as rapid as one year. |

Rack Mount 80
The RM-80 is designed for warehouses and large open rooms. The energy-efficient RM-80 is portable, being mounted on a corrosion resistant rack with castors, so it can be moved or re-located as needed in the room. The RM-80 ships factory assembled with control panel, digital humidistat and fan rheostats |
