Notes on steam distribution system OptiSorp

OptiSorp – Steam distribution system for very short humidification distance
The OptiSorp is made from stain less steel and high-grade plastic components. It is designed for connection to the Condair steam humidi fiers. The OptiSorp 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 OptiSorp 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 OptiSorp. 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 inchapter 3.7). The mounting sets comprise all necessary parts for the correct support of a OptiSorp system.

Positioning of the steam distribution system

The positioning of the steam distri bution system should be deter mined when laying out the air-conditioning system. The following points should be observed to en-sure correct humidification of the air. The conditions must be main tained exactly to ensure that the OptiSorp system satisfies the high demands made of it. A layout based on incorrect data, an unfavorable 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 fitted 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 OptiSorp steam distribution system as to the standard steam distributor pipes (see installation and operating instructions of the humidifier).

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 re fer to an air inlet temperature of 10 °C to 30 °C. The length of the steam absorption distance can be calculated more accurately with the Condair software program. The result must be compared with the actual steam absorption distance or with the minimum spacings to be observed.

Notes on installation

Before installation check that the correct OptiSorp system is used and that the system is in accord ance with the type and steam out put on the specification label.
The OptiSorp is suitable for instal lation 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 connection side of the pre-fitted system is inserted from inside through these holes.
The connector pieces are then fit ted on the pipes from outside and screwed to the duct wall. The collector pipes should be aligned hor izontally and secured at the end on the duct wall. For large systems or in special cas es, where this type of installation is not possible, the collector pipes can be fitted individually from out side. The nozzle tubes are then in serted in the collectors in the air duct and secured with the hose 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 humidifier. It is advisable to drain the con densate separately and not return it to the humidifier owing to the in creased volume.

Notes for the planning engineer

Layout
The choice of the OptiSorp steam distribution system can be made with the Condair software programme or from the layout tables. The system is determined by the number of steam connections of the steam humidifier. This also determines the maximum steam output. The max imum possible collector lengths and collector spacing is selected depending on the duct width and height.

1. For “B min.” <600 mm, the steam capacity of the corresponding system is limited to these values!.
2. If the air ducts of these systems are designed with “H min.”, the mounting plates of the steam inlet will protrude on the bottom and on the top in thin-walled air ducts. If this is not desired we recommend to design the air ducts in the total height of the OptiSorp system.

Mounting

Safety
The OptiSorp steam distribution system must only be installed by adequately qualified personnel. Observe and comply with all safety instructions in the installation and operating instructions of the steam humidifier.

Delivery
The OptiSorp steam distribution system will be delivered either premounted or as single components. Observe the corresponding mounting instructions.

Mounting positions
The OptiSorp 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 figure below).
Note: Before mounting the OptiSorp system check the type designation and steam capacity on the data plate to ensure that the correct OptiSorp 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 humidifier.

Putting into operation and operation

Putting into operation
When connected to several basic units these should be operated in parallel. Otherwise condensate runs into the units switched off and fills these until overflow occurs. Problems can then arise when switching on again.

The following should be ensured when putting into operation:

1. that the system pressure don’t increase over 1500 Pa. The system pressure is componed of the air duct static pressure, the pressure drop over the OptiSorp system (typical 500 Pa) and the back pressure in the steam hose (typical 100 Pa/m)
2. that no water splashes from the steam distribution system and the condensate runs out of the system satisfactorily. Condensating forma tion may be caused by:
   • Steam supply pipe not properly drained
   • Metallic steam pipe inadequately insulated
   • Overstressed steam generator feeds water through steam pipe
   • System condensate drain is block ed
   • Extreme back-pressure in condensate hose
   • Incorrect installation of conden sate hose

Operation

• Carry out visual checks periodically
• Further details according to the installation and operating instructions of the humidifier
