3. Unit Description
3.1 The EkoFlush-K572 is a mobile flushing unit with wheels and rugged metal structure. The
solvent cylinder required to operate the machine must have a two-way valve and must be filled
only with the flushing agent SOLSTICE
®
PF-C by HONEYWELL, pressurized with nitrogen at 8
bar.
Please consult your local dealer on connectors to attach it to the circuit you need to clean.
3.2 IMPORTANT: This Unit was designed to operate exclusively with the flushing agent
SOLSTICE
®
PF-C by HONEYWELL. If other fluids will be used, the result will be a
significant damage to the Unit and injuries for the operator.
3.3 This Unit operates on the principle of pulsating pressurized flushing of the components or
systems to be cleaned. The EkoFlush has a patent certificate. The flushing agent SOLSTICE
®
PF-C is distilled during every flow and returns to the cylinder virtually pure, ready to be re-used
for another flushing. This ensures that the cleaned components are always flushed very
effectively and fast.
3.4 The cycle has four phases.
3.4.1 I – AIR SUCKING-OFF
After having safely connected the EkoFlush unit to the circuit to flush and the solvent cylinder
with SOLSTICE
®
PF-C, and having started the operations by switching the unit on and
selected the number of flushing cycles, the EkoFlush will remove the air from the dirty circuit.
Once this phase is completed, the EkoFlush begins the automatic flushing procedure.
3.4.2 II – FLUSHING
The flushing solvent is forced into the circuit to flush thanks to the high pressure of nitrogen
(6 – 8 bar) present in the cylinder. The high pressure, the speed of the solvent flow and the
pulsation ensure that the contaminants (oil, grease, particles, water, etc…) are also removed
from every hard-to-reach corner. The full volume of the dirty circuit is filled with SOLSTICE
®
PF-C. An accurate flushing is ensured by a special pulsating mode of the solvent flow. At the
end of this phase, the EkoFlush unit pushes SOLSTICE
®
PF-C from the circuit into its
distillation chamber. Each step automatically follows the previous one without manual
intervention of the operator.
3.4.3 III – REMOVING THE LIQUID PHASE OF SOLSTICE
®
PF-C
Nitrogen from the cylinder purges the flushed component at a pressure of 6 – 8 bar in order
to quickly remove the liquid SOLSTICE
®
PF-C.
The purge is repeated a number of times until there is no more liquid in the flushed circuit.
3.4.4 IV – SUCKING OFF THE VAPOR PHASE OF THE SOLSTICE
®
PF-C
In this last step, the vapor residues of SOLSTICE
®
PF-C are extracted from the circuit and
are returned clean to the storage cylinder. An acoustic signal announces the completion of
the automatic procedure. After hearing this signal, oils, greases and contaminants can be
drained from the distillation chamber.
