IN-DUCT HIGH-PRESSURE HUMIDIFICATION

SEAMLESS INTEGRATION, MAXIMUM EFFICIENCY


At Merlin Technology, we understand that maintaining optimal indoor air quality is vital for production processes, material preservation, and overall well-being. Our in-duct high-pressure humidification solutions offer an innovative, energy-efficient alternative to conventional steam humidifiers. Designed to integrate directly into your existing ventilation or air-handling unit (AHU), an in-duct humidification system delivers precise climate control for a wide range of industries, including woodworking, electronics, automotive manufacturing, and commercial health facilities.


The core advantage of our in-duct humidification system lies in its ability to atomize water under high pressure, creating a micro-fine mist of aerosols. These tiny droplets are injected directly into the air stream. Because the aerosols are incredibly small, they evaporate almost instantly, ensuring complete moisture absorption without wetting the duct walls. This adiabatic process not only adds essential moisture to the air but also provides a natural cooling effect, which can significantly reduce the load on your facility’s cooling systems.



Switching to high-pressure in-duct humidification yields substantial financial and operational benefits. While traditional isothermal systems rely on immense amounts of electricity or gas to boil water, our high-pressure systems use a fraction of the power, offering up to 90% energy savings. Furthermore, Merlin Technology’s systems utilize reverse osmosis (RO) water to prevent mineral dust deposits, alongside automated flushing cycles that guarantee the highest hygienic standards and pure air delivery.

ORBIT WING® in-duct humidification

Short evaporation distance and extreme energy efficiency


The ORBIT WING® in-duct humidification system is an industry leader in compact design. It features a patented step element that generates micro-turbulences within the air stream. This unique aerodynamic engineering ensures that aerosols are absorbed rapidly, drastically reducing the necessary evaporation distance inside the duct. The ORBIT WING® is highly adaptable, making it perfect for retrofitting into existing air-handling units where space is limited, all while delivering superior, uniform moisture distribution with minimal pressure drop.

FORTE in-duct humidification

Easy to integrate into almost every ventilation or air-handling system


The ultrasonic humidification system Merlin FORTE works on the basis of the ultrasonic principle and humidifies the air with aerosols of 1µ.

For generating 1 kg moisture merely 52 W/h of energy is used. Compared to isothermal systems (e.g. steam humidifiers) up to

93% of energy costs are therefore saved.


Humidification output: up to 25.2 kg/h

SENSO universal humidification

Universal use, easy installation, compact design


The ultrasonic humidification system Merlin SENSO keeps classic counter-served goods considerably longer fresh and presentable. The system may, however, also be used for direct humidification at manufacturing processes.

It works on the basis of the ultrasonic principle and humidifies the air with aerosols of 1µ­.

For generating 1 kg moisture merely 98 W/h of energy is used. Compared with isothermal systems e.g. steam humidifiers up to 93% of energy costs are therefore saved. The disinfection program of the ultrasonic humidifier supports surface and room air disinfection.


Humidification output: up to 12.0 kg/h

Models

PURUS direct room humidification

Accurate and highly efficient humidification output in the smallest areas


The ultrasonic principle makes the humidifier Merlin PURUS an absolute master in saving: For each lb/kg humidification capacity the humidifier on average requires an energy expenditure of merely 92 W/h. The adiabatic humidification system withdraws transformation energy from the room air; the thus created cooling effect can be used 1:1.

Compared with isothermal systems, e.g. steam humidifiers, 93 % of energy costs are therefore saved.


Humidification output: up to 8.0 kg/h

FINESSE food humidifier

Significantly extends the freshness and shelf life of food


The ultrasonic food humidification system merlin® FINESSE keeps food considerably longer fresh and presentable.

The system is completed with a reverse osmosis and an aerosol distribution system of hydrolysis resistant, food-safe materials. Mineral deposits are completely avoided by total desalination.


Warm, dry surface climate quickly leads to water losses (through evaporation) and reduction in vitamin content (a.o. owing to CO-release) of the fresh goods. merlin® FINESSE humidifies the ambient air with a humid aerosol cloud and through that provides for 100 % saturation, which as a result leads to a‚ reduction in goods losses of 50 – 70 %. In the long term increases in turnover and profit margin of 7 – 10 % are achieved.


Humidification output: up to 3.0 kg/h
