1.1 MultiPipe – Steam distribution system for very short humidication distance

The MultiPipe is made from stainless steel and high-grade plastic compo-

nents. It is designed for con nection to the Nordmann steam humidi ers.

The MultiPipe steam distribution system is installed directly in the air duct

or in an air-handling unit. It comprises horizontal collector pipes and several

vertical pipes provided with steam nozzles. The MultiPipe separates the

condensate from the inlet steam and feeds this uniformly and drip-free to

the air ow. In particular the steam ab sorption distance is considerably less

compared with conventional steam distribution pipes.

Note: To ensure a safe support of the collector pipes we recommend the

use of the specially designed support for the steam distribution system

MultiPipe. The entire support is made from stainless steel and available in

four different mounting sets for duct heights ranging from 450 to 3200 mm

(see table in chapter 3.6). The mounting sets comprise all necessary parts

for the correct support of a MultiPipe system.

1.2 Positioning of the steam distribution system

The positioning of the steam distribution system should be determined when

laying out the air-con-ditioning system. The following points should be ob-

served to en-sure correct humidication of the air. The conditions must be

main tained exactly to ensure that the MultiPipe system satises the high

demands made of it. A layout based on incorrect data, an unfavourable

installation position or wrong installation can result in excessive humidity

with separation of condensate and therefore to damage from water. The air

duct must therefore be sealed in the area of the absorption distance and

provided with a water drainage tray with outlet. The system is preferably t-

ted immediately following the air heater (and before the cooling coils). Other

installation situations require additional care. A viewing port immediately

following the system is highly recommended for installation and inspection

of operation of the installation. Installation of the system is always made

laterally to the air ow. With vertical air ow the nozzle tubes are tted at an

angle of 20° to 30° to enable the condensate to ow away easily.

With exception of determination of the steam absorption distance, the

same basic rules apply to the MultiPipe steam distribution system as to the

standard steam distributor pipes (see installation and operating instructions

of the humidier).

1.3 Determination of steam absorption distance

Determination of the absorption distance “BN” depends on various factors.

For simple determination of the absorption distance “BN” the table can be

used. The nominal values obtained from the table refer to an air inlet tem-

perature of 10 °C to 30 °C. The result must be compared with the actual

steam absorption distance or with the minimum spacings to be observed.

1.4 Notes on installation

Before installation check that the correct MultiPipe system is used and

that the system is in accordance with the type and steam output on the

specication label.

The MultiPipe is suitable for installation in air ducts or air-conditioning units.

For this purpose the templates supplied are attached to the ventilation duct

spaced according to the collectors. The duct plate is cut out round. The con-

nection side of the pre-tted system is inserted from inside through these

holes. The connector pieces are then t ted on the pipes from outside and

screwed to the duct wall. The collector pipes should be aligned horizontally

and secured at the end on the duct wall.

For large systems or in special cases, where this type of installation is not

possible, the collector pipes can be tted individually from out side. The noz-

zle tubes are then inserted in the collectors in the air duct and secured with

the pipe clamps and O-rings. Suitable pliers are required for the installation.

All parts are supplied loose for this case if required.

Then install the steam and condensate hoses according to the instructions

in the installation and operating instructions of the humidier. It is advisable

to drain the con densate separately and not return it to the humidier owing

to the increased volume.

2 Notes for the planning engineer

2.1 Layout

The choice of the MultiPipe steam distribution system can be made from

the layout tables. The system is determined by the number of steam con-

nections of the steam humidier. This also determines the maximum steam

output. The maximum possible collector lengths and collector spacing is

selected depending on the duct width and height.

3 Mounting

3.1 Safety

The MultiPipe steam distribution system must only be installed by adequately

qualied personnel.

Observe and comply with all safety instructions in the installation and

operating instructions of the steam humidier.

3.2 Delivery

The MultiPipe steam distribution system will be delivered either premounted or

as single components. Observe the corresponding mounting instructions.

3.3 Mounting positions

The MultiPipe steam distribution system can be installed in horizontal or

vertical ducts. When mounting in a vertical duct the nozzle pipes must

have a minimum declination of 20° and the end pieces of the collector pipes

must be turned, so that the vertical condensate connection directs straight

downwards (see gure below).

Note: Before mounting the MultiPipe system check the type designation

and steam capacity on the data plate to ensure that the correct MultiPipe

system is installed in the right place.

In addition to this installation and operating instructions please observe and

comply with the instructions regarding the steam installation (positioning,

max. length of steam pipe, etc.) in the installation and operating instructions

of the steam humidier.

3.4 Mounting the premounted MultiPipe system

1. Remove the protection covers.

2. Measure the distance of the collector pipes and afx the installation

template on the duct wall at the designed place with this distance (per-

missible variation ±3 mm) and cut out the openings.

3. From inside of duct, insert the collector pipes through the prepared open-

ings.

4. Slip from the outside ange, O-ring and steam hose connections onto the

tube and x them by the four screws. Pay attention that the condensate

drains are below the steam hose connection.

5. Starting with the lowest collector pipe x the steam hose connections

with the 4 screws at the duct wall.

6. Align the collector pipes with a down-slope of 2° against the steam con-

nector. Then, fasten the pipe ends on the duct using M8 threaded rod

or the specially designed support available as accessory (see mounting

drawing in chapter 3.6).

7. Connect the steam hose and the condensate hose to each collector pipe

according to the instructions in the installation and operating instructions

of the humidier.

Note: with the system 1 connect the steam hose ø35/46 mm to the lower

steam connector DV71 and close the upper steam connector with the

sealing cap supplied.
