3 Product Overview

3.1 General Description

The Nortec EL steam humidifier is an atmospheric steam generator, which operates on the electrode heating principle. It is designed for direct room humidification using a blower pack, or humidification through the ducts in an air handling unit using a steam distributor.

The Nortec EL steam humidifier has state-of-the-art features. It has an integrated control board which not only controls the humidifier, but also allows the humidifier to be connected to a building automation system (BACnet, Lonworks, Modbus) or the internet so it can be controlled and monitored remotely.

In addition, up to six humidifiers (12 cylinders) can be set up in a main-extension configuration using

Condair's Linkup system to satisfy large humidification needs.

The Nortec EL steam humidifier comes in three different housing sizes – small, medium and large. The small and medium size models have a single steam cylinder, while the large model is equipped with dual steam cylinders. Each steam cylinder has its own dedicated driver board to receive control signal inputs. The dual driver boards allow the large models to be configured to operate in series, in parallel or independent mode to control humidity in one or more zones depending on how they are configured.

Figure 1

shows the various components of the Nortec EL steam humidifier (door panels removed for clarity).

.

Water Supply

Water enters the humidifier through the fill valve into the open fill cup with integral air gap, and then flows down through the fill hose into the steam cylinder.

Steam Generation

When the humidifier receives a signal to supply steam the contactor closes, and after a 60 second delay the fill valve opens and water enters the bottom of the steam cylinder, as described above.

As soon as the electrodes come in contact with the water, current begins to flow between the electrodes, generating heat. As the water level continues to rise, more surface of the electrodes come in contact with the water. This results in more current draw. Once the water has heated to the boiling point, steam will be produced. (

Note:

On first startup when the conductivity level of the water is low, it may take 30-

60 minutes for water to heat sufficiently to produce steam).

When the steam output reaches the requested level, the fill valve closes. As water is evaporated, the water level and current drop. When the current falls below a certain percentage of the requested level, the fill valve opens to raise the water level and the current and maintain the required steam output level.

When the actual output is higher than the requested steam output, the fill valve remains closed until the desired output level is achieved through a gradual lowering of the water level due to evaporation.

Water Level Monitoring

A sensor monitors the high water level in the steam cylinder. When the sensor detects the high water level, the fill valve closes to prevent over-filling.

Drainage

As the evaporation process continues, the conductivity level of the water increases due to the increasing levels of residual minerals left behind as the water turns into steam. This affects the current draw, which can rise beyond optimal levels. To prevent this from happening, the Nortec EL's auto-adaptive control algorithm periodically drains some concentrated water in the cylinder and replaces it with fresh water.

Control

Steam production can be controlled using the continuous proportional (P) or the proportional-integral

(PI) controller internal to the humidifier, or an external modulating controller, or with an On/Off control signal from an external humidistat.

– select the type of control signals to the humidifier ("Analog", "Modbus", "BACnet/IP", etc.,).

Select "Analog" if a sensor/transducer signal, or a demand signal from an external P/PI (pro portional)/(proportional-integral) controller is wired directly to the humidifier. Otherwise, select an applicable digital communication protocol from the list. If your humidifier has the optional

Lonworks or BACnet (BTL) module installed, select "Modbus".

Dual Cylinder Mode

(on large units with dual steam cylinders only) – select the mode of operation

("Parallel", "Series" or "Independent") of the two steam cylinders.

If two separate sets of control signals are available to the humidifier from two separate zones that require humidification, select "Independent" to operate the two steam cylinders independent of each other. Otherwise, select "Parallel" or "Series", as appropriate.

Control Channels

– select the number of control channels.

Select "Dual" if controlling the humidifier with a high limit and a control signal; otherwise set to

"Single".

Control Mode CH1/3

and

Control Mode CH2/4

– select the general control mode for the incoming control

and limit signal ("Demand", "RH P", "RH PI", or "On/Off").

Select "Demand" if the control signal is a demand signal from an external controller. Select "RH

P" or "RH PI", as appropriate, if the control signal is from a sensor/transducer. Or select "On/Off" if the control signal is from an external On/Off humidistat.

Note:

Control Mode CH2/4

must only be

set if

Control Channels

is set to "Dual".

Note:

On Nortec EL humidifiers with dual steam cylinders, if the

Dual Cylinder Mode

selection is set to "Independent" and the

Control Channels

selection is set to "Dual", the Control Mode setting and the Signal Type setting (described below) also extends to the control signals on Channel 3 and Channel 4.

Signal Type Channel 1/3

and

Signal Type Channel 2/4

– select the signal type of the incoming control

signal if

Control Mode

is set to "Demand", "RH P" or "RH PI", and signal

Source

is set to "Analog".

Select from "0-5V", "1-5V", "0-10V", "2-10V", "0-20V", "0-16V", "3.2-16V", "0-20mA", or "4-20mA", as appropriate for the external control device connected to Channel 1.

Note:

Signal Type Channel

2/4

must only be set if

Control Channels

is set to "Dual".

Enable Input

– if an external control has been connected to terminal X11 on the Nortec EL's driver board to remotely disable the humidifier, then set the Enable Input function to "On", if required.

Note:

The external contact connected to "X11" on the driver board can be used to enable or disable the humidifier. This is in addition to any On/Off devices in the safety loop or the On/Off input connected to Channel 1 that are used to enable or disable the humidifier.

This concludes the basic setup of the control software.

Note:

The humidifier can also be controlled using

Capacity Timers

, or

Setpoint Timers

, or

On/Off Timers

. If assistance is required to set it up, please contact your Condair representative.

– select the total number of humidifiers in the Linkup chain. For example, if there is one main unit and two extension units, then the total number of humidifier in the chain is 3.

4.

Linkup Type

– select the mode of operation of the humidifiers in the Linkup chain ("Series" or

"Parallel").

Sequence Rotation

– enable or disable the function that manages the starting order to balance the

operating hours on each steam cylinder.

Note:

This setting is available only if

Linkup Type

is set

to "Series".

Sequence Interval

– set the time interval used by the control software to establish a new operating sequence to balance the operating hours on the steam cylinders in the Linkup chain.

Linkup Timeout

– if required, change the maximum time limit that the units in the Linkup chain can operate without a connection to each other before they generate a Linkup Timeout warning message.

Set

Linkup

in each extension humidifier as Ext1, Ext2,...

Note:

Each extension unit must be a unique extension number.

The humidifiers in the Linkup chain are now set up to generate steam upon humidity demand.

5.1 General

Personnel Qualifications

The Nortec EL steam humidifier must only be operated by personnel who are adequately qualified, well trained and are authorized by the customer.

Safety

Certain operations of the Nortec EL steam humidifier may require the user to access the control cabinet or plumbing cabinet, which may expose the user and equipment to the hazards described below.

DANGER!

Risk of electric shock!

The Nortec EL steam humidifier is mains powered. Live parts may be exposed when the door

panels are removed. Touching live parts may cause severe injury or even death.

Prevention

: Shut down the unit as described in

"Shutting Down" on page 62

before opening the door panels.

WARNING!

Risk of severe burns from exposure to hot steam vapours!

The Nortec EL steam humidifier produces hot steam vapours. Contact with the hot steam

vapours can result in severe burns

.

Prevention

: Never open the plumbing cabinet in the humidifier while it is operating, or expose skin to escaping steam vapours.

WARNING!

Risk of severe burns from contact with hot surfaces!

Components of the steam system may reach 212

°

5.2 Operating Procedures

5.2.1 Starting Up

Start up the Nortec EL steam humidifier as follows:

1. Set the On/Off button to the On position – refer to

Figure 4 on page 13

.

The control software then starts initializing and performs system checks. When initialization and system checks are completed successfully, the Home screen is displayed on the touchscreen display

– refer to

Figure 5 on page 15

. The humidifier goes into the normal operating mode.

If a valid humidity demand signal is present the contactor closes, and after a 60 second delay the fill valve opens and begins to fill the steam cylinder(s) with water. When the water level rises and makes contact with the electrodes, the water starts to heat and the status LED turns green in color.

Depending on the conductivity of the water, it may take approximately 30-60 minutes to generate steam on the first startup.

Note:

If the water conductivity is low, it is possible that the humidifier does not output steam at full capacity during the first few hours (or even days) of operation. This is quite normal. As vaporization continues the mineral concentration increases and the conductivity of water reaches an optimum level, at which point the humidifier will start to output steam at full capacity.

If there is no humidity demand the status LED turns to a flashing green, and the humidifier goes into standby mode to await the next humidity demand signal.

5.2.2 Remote Monitoring

The Nortec EL steam humidifier can be monitored remotely if it is equipped with an optional remote fault indication board and wired to a remote monitoring system.
