Introduction

190TEN–106 5–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.

Introduction

190TEN–106 5–J 1408

2 Deh umidiﬁerde sign

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.

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 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.

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.
