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

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


Flexibility pays dividends.

All advantages at a glance.

  • A series of units for all applications and performance categories
  • Ease of installation by means of individual pre-configuration ex factory
  • Expansion of options for retrofitting
  • You only invest in the functions you really need
  • Easy operation
  • Highest quality and energy efficiency
  • Environmentally friendly incorporating reusable components

Product description

Custom made for every area of application.

The FlexLine basic model is the basis for all other configuration options. Through its individual extension capability, FlexLine is able to adapt to the requirements of differing areas of application:

  • Optimisation of the indoor climate in industrial, commercial, cultural and leisure facilities
  • Control and stabilisation of air humidity for industry and processes

Optimum humidifying using the best method.

FlexLine is available as an electrode as well as a heater element humidifier – depending on your water quality.

air humidification electrodes

Full-surface electrodes

Electrode steam humidifiers are an optimal solution when simple and reliable steam humidification is required. Due to the high amount of material, the solid full-surface electrodes of HygroMatik are particularly durable and are very well suited for use with tap water. The electrodes have to be exchanged less often, which in turn keeps the maintenance costs low.

air humidification heating element

Heater element

Steam cylinders with resistance heater elements made of highly corrosive-resistant alloy are suitable for a wide variety of water qualities, especially for treated water. They offer an extremely high level of control accuracy and ensure a virtually continuous and maintenance-free operation.

Always the correct humidification performance.

Equip HygroMatik FlexLine with the power you need for optimum humidification. 16 performance classes with steam output from 3 kg/h up to 130 kg/h selectable in 6 unit sizes. An additional performance limitation can easily be programmed.

Manifold options for a humidification solution that fits perfectly.

Due to differing spatial conditions every project places unique requirements on the humidification solution. Using the manifold options FlexLine can be specifically equipped to create the perfect solution. 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 stick.

  • At a glance comprehensible pictographs provide information on the operating condition
  • Simple and fast navigation
  • Information and system messages displayed as plain text
  • Readout of service messages with date and time
  • Integrated real-time clock
air humidification control

Smart control – powerful and quick response.

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


  • Numerous control and reporting functions can be assigned to up to 11 relays depending on the unit
  • Freely programmable with overload protected digital input

» Load shedding: power limitation in the event of network overload or emergency power operation
» Blow-down on external request for specific operating conditions
» Stand-by mode: pre-heating by remote activation for a quick response time

  • Integrated communication protocol, Modbus RTU or BAcnet

Optimised unit performance for an efficient utilisation.

As with all our products, the HygroMatik FlexLine has been developed for an expecially long life span. 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.

air humidification electrodes steam humidifier cylinder
  • Adjustable power limitation from 25 -100 %
  • Adjustable load shedding to temporarily adapt operation to the respective load conditions
  • Long-term continuous operation: A robust base material provides our reusable cylinders with high temperature resistance and dimensional stability
  • The split cylinder is easy to open and can be cleaned without chemicals
  • Extremely durable: All FlexLine cabinets are manufactured in corrosion-resistant stainless steel; the powder coating of the housing increases the lifespan and offers optimum work safety
air humidification pump
  • Robust blow-down pump for removing scale deposits to ensure long operating life cycles and minimal maintenance
  • Highest safety standard for electrode steam humidifiers due to integrated mechanical circuit breaker and mechanical safety temperature limiter for heater type steam humidifiers
  • Heater type steam humidifier with capacitive proportional water level sensor without wearing parts

Comprehensive service functions.

We have equipped the HygroMatik FlexLine with smart service functions for operational safety. These provide a new 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
