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.

2. Component
description
The components described in this chapter refer
to the images on page 3 and 4.
2.1 PAHT high-pressure pump
1
The heart of the Plug & Spray unit is the Danfoss
axial piston high-pressure pump. The pump is
water lubricated and fulls the most stringent
hygiene requirements as no lubricants or
chemicals are involved at all.
Danfoss PAHT pumps are designed for long
periods of service-free operation to provide
customers with low maintenance and life cycle
costs. Provided that the pump is installed and
operated according to Danfoss specications,
Danfoss PAHT pumps typically run 8,000 hours
between service routines.
We recommend that you inspect your pump
after 8,000 hours of operation even if it is
running without any noticeable problems.
2.2 Electric motor
2
The electric motor is dimensioned to provide
sucient power for maximum ow at 100 barg/
1,450 psig system pressure. The motor is a
standard IEC 3-phase 400 V, 50 Hz asynchronous
motor.
2.2.1 Danfoss FCP 106 drive motor
The variable speed drive motor in connection
with a pressure transmitter allows adjusting the
pump capacity to the actual demand of the
application, keeping the system pressure
constant.
The FCP 106 has a built-in PID-controller and 24 V
DC transmitter power supply.
2.6 Water lter
6
The system comprises a 5” or 10” (10, 12,5 VS),
10-micron ne lter with a β-value ≥ 5,000 abs.
The lter protects the pump against rapid wear
caused by contamination of the supply water
and – as a second benet – prevents the nozzles
from clogging. The lter cartridge is easy to
replace.
2.7 Electrical connection box, optional
7
Both CS and VS units can be delivered with an
electrical connection box, please see sec. 8.
2.8 Supply pressure gauge
8
It allows monitoring the supply pressure under
operation and the condition of the lter. The
lter should be changed when the supply
pressure is below 2 barg (29 psig).
2.9 Pressure relief valve
VRH 5 (30) CA cartridge
9
The relief valve is integrated in the connection
block with internal recirculation loop back to the
lter. It works as a safety valve in case the
discharge is blocked and allows adjusting the
system pressure under normal operation. At 20
°C (68 °F) water temperature 90% of the water
can be run over the bypass loop (recirculation).
Pressure range: 20–100 barg / 363–1450 psig
(25–140 barg / 363–2031 psig).
2.10 Filter bleed button
10
It is important that there is no air in the system.
At commissioning air can be bled from the lter
by using the lter bleed button.
2.3 Aluminium cast bell housing and
exible coupling
3
The bell housing is made of cast aluminium. The
electric motor and the pump are directly coupled
with a exible coupling. The bell housing
requires minimum space and is lightweighted.
The transmission is maintenance free and cost
ecient compared to traditional belt drives.
2.4 Galvanized steel frame
4
The base frame is designed for oor mounting;
however it can be mounted on a wall with
suitable support bars. The base frame concept
allows adding numerous options.
2.5 Connection block
5
A central connection block with integrated
pressure relief valve provides a very compact and
reliable solution to connect all other necessary
components such as gauges, switches etc.
Service friendly gasket concept:
All HP components as well as the connections to
the pump are equipped with bonded seals,
which provide easy and reliable connections.
2.11 High-pressure gauge
11
It allows monitoring the discharge pressure
under operation and during adjusting the
pressure relief valve.
Pressure range: 0-160 barg (0-2,321 psig)
2.12 Check valve - inlet 3/4”
12
In order to make back-ow impossible, a check
valve at the water supply is mandatory when
connecting the system to the public utilities.
2.13 Ball valve G 3/8” female
13
The ball valve allows to interrupt the water
supply i.e. for lter change or pump service.
2.14 Inlet G 3/4” female
14
Connect your water supply to the inlet.
2.15 High-pressure outlet G 3/8” female,
optional
15
Not used by Danfoss.

2.16 High-pressure hose
To avoid vibrations in the system Danfoss always
use a exible high-pressure hose from the pump
outlet to the connection block.
2.17 High-temperature switch
The water temperature is monitored to prevent
overheating. The switch is set to 50 °C(122 °F).

2.18 Low-pressure hose
18
To avoid vibrations in the system Danfoss always
use a exible low-pressure hose from the
connection block to the pump inlet.
2.19 MBS 3050 pressure transmitter
19
The pressure transmitter is connected to the
internal PID controller of the FCP 106 Drive
Motor, which is set up for constant pressure
Constant speed versions:
2.21 Check valve - outlet
21
The connection block is mounted with a check
valve and a male connector for a 12 mm pipe. By
removing the male connector the outlet can be
changed to G 3/4” female.
2.22 Swivel union 3/4”
22
The swivel union allows establishing the water
supply from the top, back, front or bottom.
