Steam injection humidifiers

No condensates in the air


Fisair Diphusair FSH steam injection humidifiers are steam injection humidifiers designed to operate with pressurised steam from the boiler with double jacket tubes and steam separator.

Steam injection systems are decisive in the efficiency of this type of humidifier system, as having a poor quality system can result in water condensation that is evidence of poor design. At Fisair we are aware of this and for this reason our live steam jacket guarantees that, in the event of any dripping caused by condensation, this water immediately evaporates again.

We provide our customers with the best steam injection humidifiers in 100% stainless steel, which makes them ultra-durable equipment. In addition, we are committed to energy-efficient humidification systems that achieve maximum air humidification quality at the lowest possible energy cost.
