MultiPipe – Steam distribution system for very short humidification distance
The MultiPipe is made from stain less steel and high-grade plastic compo-
nents. It is designed for con nection to the Nordmann steam humidi fiers.
The MultiPipe steam distribu tion system is installed directly in the air duct
or in an air-handling unit. It comprises horizontal collec tor 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 flow. 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 distri bution system should be deter mined when
laying out the air-con-ditioning system. The following points should be ob-
served to en-sure correct humidification of the air. The conditions must be
main tained exactly to ensure that the MultiPipe system satisfies the high
demands made of it. A layout based on incorrect data, an unfavourable
installation position or wrong instal lation can result in excessive hu midity
with separation of conden sate and therefore to damage from water. The air
duct must therefore be sealed in the area of the absorp tion distance and
provided with a water drainage tray with outlet. The system is preferably fit-
ted immedi ately following the air heater (and before the cooling coils). Other
in stallation situations require addi tional care. A viewing port immedi ately
following the system is highly recommended for installation and inspection
of operation of the instal lation. Installation of the system is always made
laterally to the air flow. With vertical air flow the nozzle tubes are fitted at an
angle of 20° to 30° to enable the condensate to flow 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 humidifier).
