How can you bring humidity to your nursing or retirement home?

Most of the humidifier technologies are offered on the market to humidify your Retirement or Nursing Home.

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 bring humidity to your retirement or nursing home. It can be installed on the central ventilation system or locally to humidify a specific zone such as special care rooms.


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.



AEM evaporative humidifier is another solution to be considered when a central ventilation system is installed. Evaporative humidifier has a low cost of ownership because it can be used during summer as an evaporative cooler reducing load on other cooling equipment installed.
