Why is humidity important for concert halls?

Humidity control is very important for concert hall where musical instruments such as piano, pipe organs, violins or other wooden and string made instruments are very sensitive to air and humidity level variation. Any relative humidity dropping below 40%RH might cause:

  • pipe organ sliders to warp and stick;
  • Any wooden instrument to warp and crack;
  • String dehydration and cracking;
  • nose and throat dryness of singers;
  • indoor space discomforts and well-being problems for musicians and , spectators, which could lead health problems due to dry air.

Therefore concert halls need to control the environment because temperature and relative humidity can fluctuate dramatically when a concert is performed in front of large audience. This requires constant operation of reliable and responsive humidification system.

Recommended humidity level for your concert hall

The recommended humidity level for Concert Hall is between 45 to 60%RH.
(Reference: ASHRAE Handbook)


How can you bring humidity to your concert hall?

Most of the humidifier technologies are offered on the market to humidify your concert hall.

Selection of the proper humidification solution should be based on the following:

  • What is the required maximum humidification capacity (load) required?
  • What sources of energy are available on site?
  • How is the ventilation system installed and how is the air distributed?
  • Which humidification system will require the least amount of energy – calculated for the overall HVAC system?

IER electric steam humidifier is an easy and efficient solution to control precise humidity level (up to +/-1%RH) to your concert hall.

ISE steam exchange or ILS Live steam humidifier are another solutions to be considered,
If raw steam from boiler is not contaminated and suitable for direct injection in the air stream, ILS humidifier is the easiest way to bring humidity to the building with a relatively low cost of ownership since minimal maintenance is required,
If raw steam from boiler is not suitable for direct injection, or if you need very safe, sterile and pure source of atmospheric steam then ISE humidifier is the best choice.

Gas fired humidifier or other technologies able to deliver large humidity capacity can be considered.
