FlexLine steam generators.
High flexibility in award-winning quality.

With the FlexLine, HygroMatik provides a modern generation of steam generators which consists of a basic model that can be expanded to create an individual solution suitable for all steam requirements. In order to make this flexibility available to you quickly, we have developed a modular system. This was awarded in three categories and FlexLine received the Plus X Award. 


Flexibility pays dividends.

Always the right performance for a rich steam picture.

Equip HygroMatik FlexLine with the power you need for optimum steam output. 16 performance classes with steam output from 10 lbs/hr up to 300 lbs/hr selectable in 6 unit sizes. An additional performance limitation can easily be programmed.

Manifold options for a steam solution that fits perfectly.

Every installation is different, and so every project places unique requirements on the steam solution. The FlexLine can be equipped with a wide range of options to optimally meet your project requirements. In addition, various protection and security functions can be installed and activated, e.g.

  • HyFlush (cylinder flushing device)
  • HyCool (integrated waste water cooling)
  • Stub line flushing

This means that your system is optimally protected around the clock and you have less maintenance work. If needed, all options can be retrofitted. We are always pleased to provide advice.

Excellent ease of operation.

All HygroMatik FlexLine units are equipped with a capacitive 3.5“ touch screen whereby operation and programming is selected via a flat and intuitive menu structure analogous to modern smartphone logic. In addition to this, subsequent software updates are quickly and easily possible via USB flash drive.

  • At a glance comprehensible pictographs provide information on the operating condition
  • Simple and fast navigation
  • Information and system messages displayed as plain text
  • Easy planning of operating periods by means of programmable timer functions
  • Readout of service messages with date and time
  • Integrated real-time clock
  • Optional: Spa Touch Control – 5“ touch screen for external control

Smart control – powerful and quick response.

The control and regulation technology of FlexLine units provides extensive possibilities that are simple and easy to operate.


  • Highest regulating accuracy and top protection from excessive temperatures by means of second supply air and ventilation steam bath fan
  • The option of up to 4 different lighting scenarios
  • Flexible switchover of up to 4 essences without changing containers
  • Freely programmable with overload protected digital input
  • Integrated communication protocol, Modbus RTU or BAcnet
  • Numerous control and reporting functions can be assigned to up to 11 relays depending on the unit

Optimized unit performance for an efficient utilization.

As with all our products, the HygroMatik FlexLine has been developed for an especially long life. The units feature technologies that not only reduce the amount of maintenance required but also the wear of components. FlexLine offers the highest degree of efficiency where energy and resources are concerned.

  • Robust blow-down pump for removing scale deposits to ensure long operating life cycles and minimal maintenance 
  • Highest safety standard for electrode steam generators due to integrated mechanical circuit breaker and mechanical safety temperature limiter for heater type steam generators
  • Heater type steam generators with capacitive proportional water level sensor without wearing parts

Comprehensive service functions.

We have equipped the HygroMatik FlexLine with smart service functions  for operational reliability. These provide a high level of safety, reliability, control and comfort.


  • Reliable: Preventive maintenance through permanent
    monitoring and intelligent evaluation of operating parameters
    can avoid unplanned downtimes
  • Convenient: Detailed messages enable deviations to be
    identified and rectified more quickly
  • Simple: The diagnostic mode can be started directly via the
    touch display without commissioning the unit completely
  • Flexible: Service intervals can be calculated by the unit according
    to time as well as the amount of steam produced
