Steam injection humidifier SIH

All components are developed in Germany and assembled according to requirements for each project. The HygroMatik steam injection humidifier SIH is available in two versions in order to optimally adapt the system to the respective application areas.

In most areas of application, the steam injection humidifier SIH stainless steel grey cast iron meets the requirements for optimum integration into the overall system. Pure steam is used for applications with demanding hygiene regulations (e.g. hospitals, laboratories and clean rooms).

The steam injection humidifier SIH 100% stainless steel meets these increased requirements. All steam-conducting components in this version are made of stainless steel 1.4401 and therefore also fulfil the increased requirements for corrosion resistance in pure steam operation.

Light, durable and optimally protected

The HygroMatik steam injection humidifier SIH is equipped with a steam lance heating piping. Therefore, an additional sheathing is not necessary for efficient humidification. The amount of condensate that reduces the efficiency is kept to a minimum.

Precise manufacturing made of high-quality stainless steel

In order to guarantee a long service life, the steam lances are made of high-quality stainless steel. Their low net weight allows a simple and fast installation. The low-noise steam nozzles draw steam centrally from the core stream, the driest area of the steam lance. In addition, the nozzles are positioned against the airflow which ensures fast distribution and a short humidification distance.

Efficient heating system: hygienic protection against condensate formation

The internal, self-contained steam lance heating system is located at the lowest point of the steam lance. This allows any condensate to be evaporated again immediately. The lightweight and easy to maintain thermal steam trap drains condensate from the heating system. The heating system is fed directly from the steam dryer.

• • Low space requirement due to internal heating system
  • Fast regulation during start-up by preheating the steam lances
  • Low heating of the air flow
  • Protection against deposition

1. High-performance steam dryer
   The stainless steel steam dryer separates the condensate from the steam using a spiral-shaped control system and is 100% maintenance free.
2. Replaceable strainer
   The high-quality stainless steel strainer protects the control valve and the steam trap from contamination from the steam network. The internal fine mesh strainer can be cleaned or easily replaced if necessary.
3. Reliable start-up safety feature
   The start-up safety feature activates humidification only after a certain operating temperature has been reached. This effectively prevents condensate from the steam network from entering the air-conditioning duct.
4. Powerful steam trap
   The robust, tight-closing ball float steam trap drains off the condensate. Due to the fast reacting principle and the high capacity, even larger quantities of condensate can be safely discharged, e.g. when starting up the system. The closed system prevents steam losses.
5. Bus-capable SIH actuator
   Safety through automatic emergency control function, optionally pneumatically controlled (0.2-1 bar)
6. SIH control valves  
   Check the steam quantity with equal-percentage characteristic curve

To better adapt our SIH pressurised steam humidifiers to the requirements of your projects, we offer the following optional components: from grey cast iron to stainless steel is possible.

SIH shut-off valves

The recommended optional shut-off valve ensures that, if required, the steam flow can be 100% shut off for any duration, independent of the control valve.

SIH manometer

The manometer for pressure indication allows the current operating pressure to be checked.
