• ILS humidifier by steamOvap is a live steam humidifier using steam from a central steam boiler. It is conditioning and distributing steam in your air handling unit (or air duct).
  • ILS humidifier is available in 3 different models: ILS-P with horizontal steam ramp and pre-heat jacket, ILS-SO with steamOsorb vertical steam ramps or ILS-SE with high efficiency steamOsorb vertical steam ramps.
  • ILS includes all the components required for the treatment and conditioning of low pressure steam such as strainer, separator, steam ramps, as well as F & T condensate trap and the actuated control valve.
  • ILS uses integral stainless steel construction of grade 304  (higher grade available upon request), a proven design and introduces world’s class electronic controller for easy start up and trouble free operation for the life of the humidifier. 
  • Optional electronic controller allows you to ease-up start-up operation and service, it is offered with Modbus, BACnet communication.
