Introduction
190TEN–106 7–J 1408
1.5 Operationmonitoring
Thedehumidifier is controlled and monitored from the control panel on the front of the unit, see section
5.1, Control panel. The HMI ( Human M achine Interface) is used to display values and parameters, and to
input settings and commands to the control system. The HMI is described in the separate supplement.
1.6 Applicationlimitations
Thedehumidifier conforms to the emission limits of residential, commercial and light-industrial
environments except for the emission limits for harmonics emission (EN 61000–3–12). As the equipment
exceeds the limits for harmonics it may not be used in residential, commercial or light-industrial
environment without taking proper steps regarding the power installation like supplying the equipment
from a dedicated transformer connected to the high or medium voltage network.
Thedehumidifier may only be used in industrial environments (class A) w hen the HMI is equipped with a
touch panel. If the HM I is equipped with a text panel, the dehumidifiermaybeusedinallenvironments
since t he text panel is approved according to class B.
1.7 Faultindications
Any faults are indi
cated by the red light on the control panel. The cause of the alarm is indicated on the
display.
1.8 Steamsupp ly
The quality of water determines the quality of steam produced. It is important that a good quality steam
supply, at the correct temperature and pressure, is available for a reliable operation of t he steam heater.
Disregarding this can lead to degradation of the heater performance and eventually to failure.
The following impurities are common in the feed water:
■
Dissolved solids – which can cause scale to form on equipment. The principal dissolved solids are
carbonate and sulphates of calcium and magnesium.
■
Suspended solids – these can cause sludge to form in the boiler. Suspended solids are usually solid
mineral or org anic particles carried in suspension in the water.
■
Dissolved gases – these can cause corrosion in equipment. The dissolved gases are oxygen and carbon
dioxide.
■
Frothing substances that can c ause contamination and corrosion of the equipment. The frothing
substances creates a foam that usually contains soda in the form of carbonates, chlorides or s ulphates.
Cor rect water treatment is required to remove the impurities in the feed water. If the impurities are not
removed there could be an overflow of boiler water into the steam s yste m .

2.1 Productdescription
The desiccant dehumidifier has been designed to effectively dehumidify the air in environments requiring
low air humidity.
All functional components are enclosed in a corrosion resistant Aluzink
®
casing (standard) or stainless steel
casing (option) which makes installation and maintenance easy. The unit is constructed on a steel base frame
which allows the use of a fork-lift truck during transportation and installation.
The electrical control system complies with standard EN 60204-1. The electrical components are mounted
on bus bars. The dehumidifier is manufactured according to European standards and the established
requirements for CE-marking.

Figure 2.1 R otor principle
1. Process air
2. Dr y air
3. Reactivation air
4. Wet air
The desiccant rotor is the adsorption dehumidifying component in the unit. The rotor structure is
comprised of a large number of small air channels.
The desiccant rotor is made of a composite material that is highly effective in attracting and retaining water
vapour. T he rotor is divided in two zones. The airflow to be dehumidified, p r ocess air, passes through the
largest zone of the rotor and then leaves the rotor as dry air. Since t he rotor rotates slowly, the incoming air
always meets a dry zone on the rotor, thus creating a continuous dehumidification process.
Theairflow tha t is used to dry t he rotor, r e a c tivation air, is heated. T he reactivation air passes through
the rotor in the opposite direction to the process air and leaves the rotor a s wet air (warm, moist air). T h is
principle enables t he dehumidifier to work effectively, even at freezing temperatures.

2.4 Configurationfeatures
This chapter includes infor mation about functions and components that can be added w hen ordering a
MX² dehumidifier. At delivery, each unit is configured according to the configuration sheet supplied with
the user manual.
2.4.1 Insulatedprocessairinlet
All dehumidifier units supplied with pre-cooled process air have insulated process air inlet. The process air
sector in front of the rotor has an internal lining of isolation to prevent condensation on the unit .
2.4.2 Processfancontrol
The process fan is equip
ped with a frequency converter for controlling the fan s peed. T he process fan
control can be configur
ed as fixed speed or variable speed according to below:
Fixed speed
The frequency conve rter for the process fan is pre-set at t he factory and the process fan always runs with a
constant speed that gives the rated process airflow.
Variable speed
The frequency conve
rter for the process fan is controlled either by flow or pressure.
At flow control, a pressure sensor measures the pressure difference over the inlet cone on the process fan. At
pressure control, a pressure sensor measures the air pressure in the dry air duct.
Th e a ctual value from the pressure sensor is calcula ted, tog e the r with the fan coefficient, by the PLC in the
control system. The PLC compares the actual value w ith the set point value and changes the command
signal to the frequency converter if there is a difference b etween the values.

7. Warm purge air
Energy Recovery Purge (ERP) is an energy saving solution that recycles heat from the rotor, after the
reactivation section in the rotational direction of the rotor. A minor part of the reactivation airflow is
bypassed to the warm sector of the r otor, before the airflow enters the r eactivation heater. The airflow
is heated up by the rotor and then mixed with the reactivation airflow, after the reactivation heater. The
recycled heat from t he rotor increases the efficiency and r educes the energy consumption.
Compared to a standard unit, ERP will give the same dehumidification capacity with reduced reactivation
heater energy.
