Purus Air Humidifier

Direct Room Humidification

Purus Air Humidifier


Merlin Purus Air Humidifier

The ultrasonic principle makes the air humidifier Merlin Purus an absolute master in savings.

For each kg humidification capacity, the humidifier on average requires an energy expenditure of merely 0.092 kW/h.

The adiabatic humidification system withdraws and transforms energy from the room air therefore the created cooling effect can be used at a 1:1 ratio.

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

Guarantees accurate and highly efficient humidification performance in the smallest spaces

Water is atomized by ultrasonic vibrations of 1.7 MHz into aerosols of 1 ¼m. An integrated fan distributes them via the air flow into the room, the aerosol mist (cold vapour) mixes with the ambient air, evaporates completely and is distributed efficiently and evenly throughout the room.
