1. General information
The Danfoss Plug & Spray unit is designed for
humidication and adiabatic cooling systems
based on the high-pressure principle. The units
are available in a constant speed version (CS)
with IEC electric motor, as well as in a version
with constant pressure control using a Danfoss
FCP 106 variable speed drive motor (VS).
The Plug & Spray unit is available with 6 dierent
pump sizes (see Technical data, sec. 4) to match
the required ow demand. The motor power is
dimensioned to provide design ow at
a system pressure of max. 100 barg or 1,450 psig.
The Danfoss high-pressure axial piston pumps
provide excellent pressure stability at high
energy eciency and low noise level. Pulsation
dampeners are superuous.
The Plug & Spray unit comprises all necessary
components to ensure the best possible
performance, maximum service life with
maximum protection of the pump. It is very
compact, requires very little space and is suitable
for both wall and oor mounting.
The Danfoss Plug & Spray unit can be operated
with ordinary tap water as well as with all kinds
of technical water (distilled, de-ionised and
demineralised water).
The Plug & Spray unit is suitable for a variety of
applications, such as:
• High-pressure hymidication and adia batic
cooling in HVAC systems (Air-handling
units) i.e. in oces, server rooms etc.
• Open space humidication system in
production halls, storages etc.
• Humidication and adiabatic cooling
in animal farms, greenhouses and composting, server rooms
• Electrostatic Discharge (ESD) control
• Adiabatic outdoor cooling i.e. in pools,
bars, restaurants etc.
• Dust suppression and dust binding in
manufacturing and clean rooms
• Gas turbine inlet cooling and NOx control
• Odour control and soil lters
• Water mist clouds in theme parks,
exhibitions etc.
