INSTALLATION AND OPERATING INSTRUCTIONS

Possible applications for the Condair Esco live steam humidication system
In the proximity of machinery and production processes, op-
timal air humidity is essential. Of course for hospitals, as well
as clinics, laboratories, and the chemical and pharmaceutical
industries, air humidity and hygiene is an absolute necessity.
In storage rooms, where organic matter like sh, vegetables
or tobacco is kept for longer periods of time, optimal air humid-
ity will prevent undesired drying and preserve the freshness.
It improves the health and well-being of people, animals and
plants, especially during the heating season. Condair Esco’s
steam air humidication system satises these requirements
to a high degree.
Using steam to humidify the air...
• is indisputably the most hygienic method (sterile)
• causes no disturbing odours
• hardly affects the temperature of the air (isothermal)
• prevents waterborne mineral deposits from accumulating in
air ducts and rooms
• allows optimal control of the air humidity
• requires minimal maintenance
Why humidify with steam?
To humidify the air with water vapour is the most direct, sim-
plest, and safest method. Humidity contained in air is called
water vapour. To humidify the air means increasing its water
vapour content. The Condair Esco steam humidication system
raises the lacking humidity to the proper, optimal value without
any undesired side-effects.

1 Important notes
Please read this chapter carefully. It contains important information,
which must be observed for safe, correct, and economic operation of
the steam humidication system Condair Esco.
1.1 Correct use for intended purpose
Steam humidication systems Condair Esco are intended exclusively for
indirect humidication via steam distribution pipe in a ventilation duct. For
applications in process technology systems, please consult the supplier. Any
other type of application is considered as not conforming with the intended
purpose. The supplier cannot be made liable for any damage resulting
from improper use. The user bears full responsibility.
Correct use for intended purpose further includes:
• Observation of the instructions, regulations and notes contained in the
present installation and operating instructions for the steam humidica-
tion system Condair Esco.
• These installation and operating instructions contain all information
required for planning a humidication project which utilises the steam
humidication system Condair Esco. In addition, it contains all informa-
tion necessary to install such a system.
• The installation and operating instructions are intended for use by engi-
neers, planning personnel and system constructors entrusted with the
design of humidication systems. It is assumed, that these persons have
a good understanding of the ventilation and humidication technology.
• The steam humidication system Condair Esco incorporates the lat-
est technical advances and meets all recognised safety regulations
(manufacturer’s statement). Ignorance of appliance-specic qualities or
improper use, however, can result in danger to the user or third parties
and/or impairment of the system and other material values.
• The notes in the installation and operating instructions concerning the
planning /layout of a humidication system, and the installation details
for the steam humidication system Condair Esco must be observed
and followed without fail.

The following points must be observed in addition to these installation and
operating instructions:
• All local safety regulations concerning the use of pressurised steam
systems.
• All local safety regulations concerning the use of mains-supplied electri-
cal equipment.
• All instructions and warnings in the publications for the products used
in conjunction with the steam humidication system Condair Esco.
• All safety regulations concerning the system in which the steam humidi-
cation system Condair Esco is tted.
• All instructions and warnings provided on the steam humidication
system Condair Esco.
• All local sanitary regulations.
The well organised world-wide Condair distributor network provides service
at all times by qualied technicians. Please contact your supplier if you have
any queries concerning the steam humidication system Condair Esco or
humidication technology in general.
1.2 Safety instructions
• The steam humidication system Condair Esco must only be installed,
operated and serviced by persons familiar with this product and suf-
ciently qualied for the task. The customer must ensure that the installa-
tion and operating instructions are supplemented by internal instructions
with respect to supervisory and notication liability, work organisation,
personnel qualication, etc.
• Persons unfamiliar with the operating instructions must neither operate

2 The Humidier
2.1 Steam humidication system Condair Esco
Wherever existing steam is employed for humidication, the steam humidi-
cation systems Condair Esco, DR73 and DL40 prove to be outstanding.
The precisely controlled steam mass ow is evenly distributed into
the air current, void of any condensate spray. Steam humidication
systems Condair Esco, type DR73 and DL40 operate very reliably. They
are compact, easily installed, and thanks to computerised layout, permit
a system-optimised humidication distance. The absolutely steam-tight
rotary-disk control valve prevents temperature energy losses in the
closed position.
•Safe operation
Strainers, water separators, as well as primary and secondary conden-
sate drains ensure clean, condensate-free steam.The nozzles, tap-
ping the steam at the centre of the distribution pipe, render the jacket
heating unnecessary, because accumulating condensate is drained via
secondary steam trap.
• Compact
Strainer, water separator, steam trap, rotary-disk control valve and rotary
actuator form a compact unit, requiring little space.
•Easy to install
Combining all important parts into one compact unit, averts the need
for expensive additional installations and prevents sealing problems
during installation.
