1.General information The Danfoss Plug & Spray unit is designed for
humidification 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 different pump sizes (see Technical data, sec. 4) to match the required flow demand. The motor power is dimensioned to provide design flow 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 efficiency and low noise level. Pulsation dampeners are superfluous.
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 floor 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 hymidification and adiabatic cooling in HVAC systems (Air-handling units) i.e. in offices, server rooms etc.
•Open space humidification system in production halls, storages etc.
•Humidification 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 filters
•Water mist clouds in theme parks, exhibitions etc.
