2. General performance

The Nessie high-pressure water products from Danfoss are designed
to operate on clean tap or potable water and technical water with
low conductivity (De-Mineralized, De-Ionized, Reverse Osmosis).
Danfoss defines clean tap water as water filtered to 10 µm absolute,
β value > than 5000. This means that the water is filtered to a level
where 99.995% of all particles larger than10 µm have been filtered out.
Since Nessie pumps are water lubricated and cooled, failing to meet
the water quality specification will reduce the expected service life
of the components and void the limited warranty. It should be noted
that systems with high-pressure atomization nozzles require a high
filtration degree of the water to ensure optimal performance of the
spray nozzles.
It is the responsibility of the end-user to provide sufficient feed water.

water temperatures of 3°C to 50°C (37°F to 122°F). Operation outside
this area may cause damage to the system.
