Introduction
190TEN–106 5–J 1408
1.5 Operationmonitoring
Thedehumidier 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
Thedehumidier 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.
Thedehumidier 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 dehumidiermaybeusedinallenvironments
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.

Introduction

2.1 Productdescription
The desiccant dehumidier 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 dehumidier 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 airow to be dehumidied, 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 dehumidication process.
Theairow 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 dehumidier 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 dehumidier. At delivery, each unit is congured according to the conguration sheet supplied with
the user manual.
2.4.1 Insulatedprocessairinlet
All dehumidier 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 congur
ed as xed 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 airow.
Variable speed
The frequency conve
rter for the process fan is controlled either by ow or pressure.
At ow 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 coefcient, 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.

5. Dry air
6. Purge air
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 airow is
bypassed to the warm sector of the r otor, before the airow enters the r eactivation heater. The airow
is heated up by the rotor and then mixed with the reactivation airow, after the reactivation heater. The
recycled heat from t he rotor increases the efciency and r educes the energy consumption.
Compared to a standard unit, ERP will give the same dehumidication capacity with reduced reactivation
heater energy.
2.5 Hightemperaturecut-out
The unit is equipped with a high temperature cut-out (HTC O), which prevents the unit from being
overheated and damaged if the reactivation air is too hot. T he HTCO switches off the heater if the
temperature exceeds the HTCO setting.
The HT CO t herm ostat housing is located beside the electrical panel, see Figur e 2.5 . A resetting button
is located on the back of the thermostat housing.
The HTCO bulb is located in the reactivation air duct. When the HTCO trips, the message "React Heater
HTCO" is shown on the control panel display.
