Always the right performance for a rich steam picture.

Equip HygroMatik FlexLine Plus Spa with the power you need for optimum steam output. 7 performance classes
with steam output from 9 to 115 lbs/hr selectable in one unit size. In addition, individual performance adjustments
can be programmed both at the factory and on site.

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

The stainless steel cylinders of the HygroMatik FlexLine Plus Spa
generate hygienic, mineral-free steam and are explicitly designed for
spa and wellness applications.


  • 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

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 mineral 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.


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

Excellent ease of operation.

All HygroMatik FlexLine Plus Spa units are equipped with a capacitive 3.5“ touch display. Operation and
programming are 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.

  • 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 display for external control

Smart control - powerful and quick response.

The improved control and regulation technology of the HygroMatik FlexLine Plus Spa units provides extensive
possibilities that are simple and easy to operate.


  • Highest regulating accuracy and top protection against 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, 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

Durable and safe.

HygroMatik FlexLine Plus Spa 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 corrosion-resistant 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 protection.

Optimized unit performance for efficient utilization.

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

  • Adjustable power limitation from 25-100 %
  • Adjustable load shedding to temporarily adapt operation to the respective load conditions
  • Active energy saving with the ECO function and flexible adjustment of the timer functions
  • Long-term continuous operation: A robust base material provides our reusable cylinders to achieve a high temperature resistance and dimensional stability
  • The split cylinder is easy to open and can be cleaned without using 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
  • Robust blowdown 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 steam generators with electronic, proportional level control with no wear parts

Comprehensive service functions.

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


  • Innovative: 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
