FlexLine Plus and Process

for precision and process humidification.

A stable and controlled room climate is indispensable for many production processes. Fluctuations in air
humidity and especially excessively dry air have a massive influence on the raw materials used, on their
processing capabilities and thus ultimately also on the quality of the end products.

HygroMatik FlexLine Plus and Process heater steam humidifiers have been developed especially for
the use in precision and process humidification, in sensitive areas of industrial production as well as for
the stabilisation of the relative air humidity in laboratories and research facilities.

All advantages at a glance.

Advantages for the operator


  • Precise control and reliable stabilisation of air humidity in the ambient and room air
  • Increased process efficiency by reducing errors and failures
  • Increased productivity and product quality
  • Protection against dangerous electrostatic discharges
  • Healthy and pleasant working environment for employees

FlexLine Plus and Process
Maximum flexibility that pays for itself.

As part of the FlexLine series, a new generation of steam humidifiers, the HygroMatik FlexLine Plus and Process
units can be flexibly expanded from a basic model with appropriate options. Every humidifier can thus be optimally
adapted to the individual requirements of a project.


Advantages for project planning


  • Reduction of installation complexity by means of individual pre-configuration ex factory
  • Optimum connection to the building management system
  • Optional Modbus or BacNet
  • Retrofittable with optional expansion options
  • You only invest in the functions you really need

The optimal humidification performance.

Equip the HygroMatik FlexLine Plus and Process with the power you need for optimum humidification performance.
There are seven output classes from 5 to 50 kg/h steam output in one unit size to choose from. In addition, individual
performance adjustments can be programmed both at the factory and on site. Higher humidification performance is
achieved by connecting units together.

Many options for individual configuration.

The respective basic model of the FlexLine is the basis for all other configuration options. Thanks to their individual
equipment, HygroMatik FlexLine Plus and Process can be adjusted to the requirements of various industrial and
process control applications and equipped with a wide range of options so that they optimally meet every project
requirement (e.g. HyCool – integrated waste water cooling). These options can also be retrofitted as needed.

The robust stainless steel cylinders – high quality and hygienically clean.

In some application areas, such as hospitals or other medical areas,
stainless steel cylinders are sometimes preferred. The stainless steel
cylinders of HygroMatik FlexLine Plus and Process generate
hygienic, mineral free steam and are designed accordingly for these


  • The stainless steel split cylinders can be opened easily and
    cleaned without chemicals
  • The robust heater mounting allows a simple and fast installation
    and removal of the heating elements
  • Available in two cylinder sizes with volumes attuned to the
    humidification capacity
air humidification systems certified hygienic

Compact and low-maintenance.

When operated with softened or tap water, the minerals and salts contained in the water precipitate. These
deposits are stirred up by the integrated rinsing and lime collection system during partial blowdown and can
be removed by the powerful blowdown pump. The amount of particles accumulated in the strainer is thus
significantly reduced.


  • Robust removable strainer allows easy removal of hardeners
  • The combined rinsing and lime collection system is integrated in the unit and ensures compact dimensions
    for HygroMatik FlexLine Plus and Process
  • Plug connections, cylinder clamping ring and steam hose adapter enable fast and easy maintenance

Durable and safe.

HygroMatik FlexLine Plus and Process units heat the water with the aid of one,
three or six resistance heaters in the stainless steel cylinder according to the
immersion heater principle. The heaters are made of highly corrosionresistant
Incoloy825 (chromium nickel molybdenum alloy) and therefore
extremely durable. The mechanical overheating protection of the heaters
together with the electronic proportional level control provides double

Robust and efficient.

HygroMatik FlexLine Plus and Process have been developed, like all our products, for particularly long operating times. The units are characterised by technologies that, in addition to the maintenance effort, minimise the wear of unit components and use energy and resources in a highly efficient manner.

  • Extremely durable: All FlexLine cabinets and cylinders are made of corrosion-resistant stainless steel; the powder coating of the cabinet further increases the durability and offers optimum occupational safety
  • Heater steam humidifier with robust, contactless and therefore wear-free level control
  • Robust blowdown pump for removing hardeners to ensure long operating life cycles and low maintenance requirement
  • Adjustable load shedding between 25 and 100% for temporary or permanent
    adjustment of the operation to the respective load conditions

Excellent ease of operation.

All HygroMatik FlexLine Plus and Process units are equipped with a capacitive 3.5“ touch display.
Operation and programming is made 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 are displayed as plain text
  • Readout of service messages with date and time
  • Integrated real-time clock

Intelligent and responsive.

The improved control and regulation technology of HygroMatik FlexLine Plus and Process units offers extensive possibilities with equally simple and comfortable operation.

  • Numerous control and reporting functions can be assigned up to 11 relays depending on the unit
  • Freely programmable, 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


Safety and service.

We have equipped the HygroMatik FlexLine Plus and Process units
with intelligent service functions for operational safety. These offer 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

The HygroMatik FlexLine Process
Perfect precision.

The HygroMatik FlexLine Process units are the solution for all applications in which constant humidification values are decisive for quality, for example the humidification of demanding production processes. Other common applications are test benches which require exact and constant reproducible ambient conditions for valid results.

The HygroMatik FlexLine Process offers all the
advantages of FlexLine Plus and supplements them
with increased control accuracy of up to +/- 0.5 %. 
To achieve this, the FlexLine Process is operated
exclusively with fully demineralised water and therefore
runs almost maintenance-free and without interruption.


The 4-fold solenoid valve is responsible for the control
accuracy of the precision control which ensures
continuous and steady feeding of the water into the
cylinder without interruption.


Another important feature is the additional analogue
input for connecting a second humidity sensor.


This enables sliding maximum limitation. This means
that the steam output adapts smoothly to the maximum
value and interruptions caused by switching off steam
production are avoided.
