Steam spray unit for low temperature humidification SBA Type
[Unit built-in/to be built into the Air handling unit, total heat exchanger, humidification chamber]
With the steam humidification, humidification of low temperature air has been a challenge. This system can provide a solution to this problem.
Provides humidification to all fresh air system A/C and fresh air cooling, such as in the hospitals and factories Type SBA is a steam spray unit, which is built into the Air handling unit and humidification chamber, to provide steam humidification to low temperature air. This can be used for the all outdoor air system A/C and outdoor air cooling.
Until now, when humidifier is integrated into an Air handling unit, condensation and dew formation may have occurred at a low temperature of circulation air.
Based on many years of technology and experience in humidification, Wetmaster developed an innovative steam spray unit. After analyzing the field problems and repeating tests and researches with the unit, we have validated the performance and have finally commercialized it as a proprietary "low temperature humidification steam spray unit."
This unit does not develop condensation and dew formation at a low temperature between 12-20deg.C and can provide reliable humidification.
