FlexLine Plus and Processsteam humidifiersPrecision and process
humidification in amodular system• High control accuracy of up to +/- 2% RH• Uninterruptible steam production with demineralised water• Hygienic humidification with mineral-free steam• Absolutely reliable through high-quality components• Steam cylinders made of corrosion-resistant stainless steel

2Many options forindividual configuration
The respective basic model of the FlexLine is the basis for all otherconfiguration options. Thanks to their individual equipment, Munters
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.
These options can also be retrofitted as needed.
Example option:• HyCool (integrated waste water cooling)• Extended reporting functions

Highest quality andprecision throughcontrolled air humidity
A stable and controlled room climate is indispensable for many production
processes. Fluctuations in air humidity and especially excessively dry air have amassive influence on the raw materials used, on their processing capabilities andthus ultimately also on the quality of the end products.
Munters FlexLine Plus and Process heater steam humidifiers have beendeveloped especially for the use in precision and process humidification, insensitive areas of industrial production as well as for the stabilisation of the relative
air humidity in laboratories and research facilities.
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

4Maximum flexibility
that pays for itself
As part of the FlexLine series, a new generation of steam humidifiers, the units canbe 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• Optionally Modbus or BacNet• Retrofittable with optional expansion options• You only invest in the functions you really need5

The optimal humidification
performance
Equip the Munters 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 performanceadjustments can be programmed both at the factory and on site. Higher
humidification performance is achieved by connecting units together.

The robust stainless steel cylinders – high quality andhygienically clean

Durable and safe
Munters FlexLine Plus and Process 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 Incoloy 825 (chrome-nickel-molybdenum alloy) andtherefore extremely durable. The mechanical overheating protection of
the heaters together with the electronic proportional level control provides
double protection.

In some application areas, such as hospitals or other medical areas,
stainless steel cylinders are sometimes preferred. The stainless steel
cylinders of Munters FlexLine Plus and Process generate hygienic,
mineral-free steam and are designed accordingly for these applications.
• The stainless steel split cylinders can be opened easily and cleaned
without chemicals• The robust heater mounting allows a simple and fast installation andremoval of the heating elements• Available in two cylinder sizes with volumes attuned to thehumidification capacity

Resistor type heater elements in highly
corrosion-resistant alloy

Robust and efficient
Munters FlexLine Plus and Process have been developed, like all ourproducts, for particularly long operating times. The units are characterised bytechnologies that, in addition to the maintenance effort, minimise the wear ofunit components and use energy and resources in a highly efficient manner.
• Extremely durable: All FlexLine cabinets and cylinders are made ofcorrosion-resistant stainless steel; the powder coating of the cabinet
further increases the durability and offers optimum occupational safety

Compact and low-maintenance
When operated with softened or tap water, the minerals and salts
contained in the water precipitate. These deposits are stirred upby 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.

Large cylinder (FLP30 - FLP50)• Heater steam humidifier with robust, contactless and therefore wearfree
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• Robust removable strainer allows easy removal of hardeners• The combined rinsing and lime collection system is integrated inthe unit and ensures compact dimensions for Munters FlexLine Plusand Process• Plug connections, cylinder clamping ring and steam hose adapter
enable fast and easy maintenancer

Excellent ease of operation
All Munters FlexLine Plus and Process units areequipped with a capacitive 3.5“ touch display.
Operation and programming is made via a flatand 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 clockIntelligent and responsive
The improved control and regulation technology of Munters
FlexLine Plus and Process units offers extensive possibilities
with equally simple and comfortable operation.
• Multi-unit operation management caters for optimum
allocation and capacity utilisation when operatingmultiple units and safeguards the air humidity even whena unit is being serviced• Numerous control and signalling functions can be assigned up to ten relays
depending on the unit
• Up to two freely programmable, overload-protected digital inputs• Integrated communication protocol Modbus RTU or BACnet

All in the green zone
• Robust and durable cabinet• Reusable steam cylinders• Long and flexible service intervals• High resource efficiency

Safety and service
We have equipped the Munters FlexLine Plus and Process units withintelligent service functions and innovative features for operational safety.
These offer a new level of safety, reliability, overview and comfort.
• Diagnosis mode can be actuated directly via the touch display without having
to start the whole unit
• Service messages easily selectable• Service intervals are calculated and released by the unit according to theamount of steam produced• Smart controlled status messages avoid damage and expensive service
operations• Detailed messages enable deviations to be identified and rectified sooner

The FlexLine Process: maximum control accuracy and precision
The Munters FlexLine Process units are the solution for all applications inwhich constant humidification values are decisive for quality, for example thehumidification of demanding production processes. Other common applications
are test benches which require exact and constant reproducible ambientconditions for valid results.
The Munters FlexLine Process offers all the advantages of FlexLine Plus andsupplements them with increased control accuracy of up to +/- 0.5 % RH. 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 precisioncontrol which ensures continuous and steady feeding of the water into the cylinder
without interruption.
Another important feature is the additional analogue input for connecting asecond humidity sensor. This enables sliding maximum limitation. This means thatthe steam output adapts smoothly to the maximum value and interruptions causedby switching off steam production are avoided.
