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

With the FlexLine, HygroMatik provides a new 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 our customers quickly, we have developed a modular system. This was awarded in three categories with the Plus X Award and named Product of the Year 2018.


Flexibility pays dividends.

All advantages at a glance.

Using the best method for optimum steam production.

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

air humidification electrodes

Full-surface electrodes

Electrode steam generators are an optimal solution when simple and reliable steam production 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.

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 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 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 steam solution that fits perfectly.

Due to differing spatial conditions every project places unique requirements on the steam solution. Using the manifold options FlexLine can be specifically equipped to create the perfect solution. Whether you choose HyCool, (integrated waste water cooling) or the SuperFlush function (cylinder flushing device) depends entirely on your project. We are always pleased to provide advice.

  • Optional: Spa Touch Control – 5“ touch screen for external 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.

  • 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
  • 53 different control and reporting functions can be assigned to up to 11 relays depending on the unit

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.
