Droplet Separator; Hydraulics Connections - Elsteam HPN Series User, Installation And Maintenance Manual

HighPressure Humidifier - Constant Pressure
The nozzle lines must be connected in thermal contact with heating batteries in AHU, to be sure the
stainless steel pipes are always at drying temperature when the humidifiers is not working. This will dry
the empty network avoiding all possibilities of microbes growth and proliferation.
When installing the distribution rack (inside the AHU) the holes opened in the panel of the
must be closed using permanent elastic sealant that fulfils the requirement of the standard
VDI 6022-1.

7.4 Droplet separator

The "droplet separator" is made of stainless steel frame and glass fiber panel. It must be installed (only in
AHU) at minimum 150cm from the distribution network. It is care of the AHU manufacturer to make
stainless steel frame avoiding sharp edges and all corner than can allow dust deposits. Permanent elastic
sealant must be used in such a way to avoid dirt accumulation (make surfaces as smooth as possible).
The droplet separator must be easily removable to perform maintenance operation or unit replacing. As
the droplet eliminator is not intended to be cleaned, it must be replaced at end of its lifetime.
When installing the droplet separator (inside the AHU) the holes opened in the panel of the
must be closed using permanent elastic sealant that fulfils the requirement of the standard
VDI 6022-1.

7.5 Hydraulics connections

The connection between the pump and distribution network must be realized using pipes which supports
nominal pressure of 100bar (minimum), due to the high pressure (80 bar) in the network. It is preferable
to use stainless steel material.
Hydraulic connections are positioned on side panels of the cabinet. Input water connection is 3/4" and is
on the right side of the case; output is 3/8" and is on the left side.
A shut-off valve must be installed upstream (and nearby) humidifier for maintenance and
safety reasons operations.
Before installing the nozzles, it is mandatory to carry out a cleaning phase of the pipes
