Comparison of the diffrent types of humidification systems

It is typical plant constructions that are used as basis for the below comparison, except for high-pressure which is ML system.

	ML High-pressure	Steam	Ultrasonic	Compres-sed air	Water wall
Energy costs	Low	High	High	Middle/high	Low
Water consumption	Low	Yes, 50% in drain	Middle	Low	High
Cooling effect & temperature reducing	Yes	No	Yes	Yes	Partly
Operation of ventilation system is necessary to humidify	No	No/Yes	No/Yes	No	Yes
Possibility of reduction in draining charge	Yes	No	No	Yes	No
Service costs	Middle	High	High	Middle	High
Compressor	No	No	No/yes	Yes	No
Noise level	Low	Low	Low	High	Low
Use of excessive heat	Yes	No	Yes/no	Yes	No
