humiSonic direct was awarded in Mostra Convegno Expocomfort 2016 as one of the most efficient and innovative humidification systems. This humidifier stands out thanks to its excellent performance, that guarantee maximum reliability and minimal maintenance, 90% energy saving compared to a steam humidifier and instant absorption of the nebulized droplets. Thanks to the low consumption of energy humiSonic is the ideal solution for data centers and for all those applications in which humidity control can be carried out at the expenses of the sensible heat generated within the room. The environment as well takes advantage of humiSonic’s high efficiency. If used to replace an isothermal system in a small data center, with a humidity request of 10 kg/h, the emission of 9 tons of CO2 each year would be avoided.

5. Agenda
 Isothermal vs adiabatic humidification
 Ultrasonic humidification
 humiSonic direct: features
 Applications

6. • Dry bulb temperature is the one we
normally perceive. It is a measure of
sensible heat.
• Relative humidity is the value that
indicates how far the air is from
saturation. When air is 100% saturated
condensate starts forming.
• The capacity of air to contain
humidity increases with
temperature.
Steam vs adiabatic technologies

7. • Isothermal humidification is achieved
by introducing steam into the air
• Energy for the water to steam change
of state (≈700W/l) is provided
externally. Enthalpy increases
• Air temperature does not change
(hence isothermal)
Steam vs adiabatic technologies
STEAM HUMIDIFICATION

8. • Adiabatic humidification is achieved by
spraying fine water droplets
• Water spontaneously evaporates
• Energy for the change of state is provided
by air. The total amount of energy does
not change (hence adiabatic)
• Sensible heat is converted into latent heat
Air is cooled

Ultrasonic humidification
Water nebulization happens due to a double
effect:
CAVITATION
The rapid vibration creates small cavitation
air bubbles which explode on the surface
releasing microscopic droplets
CAPILLARY WAVE
Waves generated in the water tank by the
oscillators release droplets

13. STAND‐ALONE UNIT
humiSonic needs just the power, RO
water and drain connections:
 control/electrical panel is not
needed
 built‐in humidity probe

hygiene on adiabatic solutions is a must for CAREL
 automatic washing cycles management
 automatic tank drain if shut down
 each component in touch with
water is stainless steel made
 humiSonic uses fresh RO water with the additional safety
of the UV lamp
Features

21. MASTER/SLAVE
for extra capacity demand or homogeneous humidity
distribution a master unit can drive up to three humiSonic,
for a total system capacity of 32 kg/h.
Each slave unit matches the master status.
