2 Technical Data
2.1 Range of Application and Intended Use
Product description:
EcoDose 2K (ED2K) is a machine designed for dosing and mixing fluid
components (typically bases and catalyst) according to pre-defined ratios.
It is intended to be used in all applications based on “two components”
process, in which two liquids, base and catalyst, are mixed together to have a
chemical reaction to reach the final state suitable to cover surfaces in general.
Typically, ED2K is used in painting process of any kind, and in every surface
protecting process by spraying liquid materials.
It can be used in manual application and in automatic application; in this case
it communicates with any kind of PLC/PC controlled device, with Ethernet
interface, and allows a complete automated functioning, including of
safety/alarms management, interchange of relevant process data, 4.0 industry
compliance.
The machine is complete of a base plate, a main support, an electrical cabinet,
a pneumatic cabinet, a fluidic panel. Mixing of fluids is performed into the
fluidic panel, using flow meters, pneumatic valves, static mixing devices.
According to type of flow meters used, are available two versions, with Coriolis
flow meters and with Gear flow meters, each of them in high pressure or low
pressure. EcoDose 2K was built exclusively for use in the field of surface finish
or similar activities
EcoDose should be installed, maintained and repaired only by persons who
know the equipment very well and have been made aware about the dangers.
The main rules for the prevention of accidents must be respected, as well as
the rules for safety.
The commands of EcoDose 2K have been designed exclusively for the
activity of dosing components with the mixing machinery EcoDose 2K.
The password to change the input parameters has to be provided only to
trained personnel.
Use EcoDose 2K only for products that are compatible with its components.

Grounding
The metal parts of the plants subject to contact with people who for lack of insulation or
other causes may be energized, must be grounded. In this regard, on the base of the
machine there is a point of contact identified by an adhesive (see drawing) for the
connection with the network of general grounding of establishment.

The machine is feed with two components by a pumping system (pos. 4+6+7
in figure) not included into the machine, and with compressed air through an
inlet filter/regulator kit (pos. 5+8 in figure).
Compressed air (marked in blue in figure) is used into pneumatic section of
control panel to operate valves into the machine.
The two components feed directly the Fluidic Panel by plastic hoses (marked
in red in figure). Output of the Fluidic Panel is delivered to a gun, manual or
automatic (pos. 10 in figure), that is not included into the machine.
Fluidic Panel can be assembled on the metallic stand, above the control panel
(see figure Version: Stand Alone) or installed internally the room in which
spraying is performed, typically paint booth, normally classified Atex Zone 2
(see figure Version: Separate).
Control logic is electronic, driven by the control panel that can be managed
by operator directly by a touch screen on the front of the panel, or via optional
remoted magnetic switch panel (pos. 12 in figure).
All cable connections between control panel and Fluidic Panel (marked in
dashed black line in figure) are suitable to Atex certification of fluidic panel.
In automatic configuration, the control panel dialog with other electronic
devices, as line control master, by an Ethernet connection (marked in dashed
black line in figure); in this case, the assembly of the machine is identical to
manual version, only software logic act differently.
Machine can be completed with none, 1 or 2 optional mechanical devices to
clean the gun, named EcoGunCleaner M, (pos. 11 in figure), installed inside
the spraying booth, and connected with control panel by a compressed air
command pipe (marked in blue in figure).

The operator may only carry out the installation, commissioning, maintenance,
repair and cleaning activities expressly described in this operating manual. All
the operations not described in this manual can only be carried out by the
manufacturer. For all maintenance, repair and cleaning activities, you must
observe the industrial safety regulations applicable at the place of the
installation.
3.2 Use of Tools in Ex Zones
The spraybooth is classified once into ex zones according to UNI EN
16985:2019. Ex zones are defined beforehand and are effective
independentently of the installation's operating condition. Even a sufficiently
ventilated spraybooth which does not contain any inflammable material is still
considered as ex zone.
According to DIN EN 50176, only accessories meeting the requirements of EN
60079-0 and/or EN ISO 80079-36 can be used in an ex zone.
UNI EN 16985:2019 always requires a technical ventilation inside the
spraybooth. Spraybooths with fresh air inletsare provided a sufficient
ventilation after 3 to 10 air exchanges. As a rule, the spraybooth is sufficiently
ventilated after 5 minutes. In air recirculation installations, a ventilating time of
30 minutes [4] is necessary to achieve a sufficient ventilation, depending on
the mixture ratio of recirculating air to fresh air.
The use of not classified tools pursuant to the regulations for protection against
explosions in hazardous areas is the customer's exclusive responsibility.
- The customer has to carry out a risk assessment for every
operation performed, to document them and to prepare an
operating manual on the basis of the resulting evaluation.
- The customer has to ensure that all operators carrying out their
own respective tasks know and observe these measures.
[4] This value is dependent on the design and settings and must always be
determined on the basis of the system-specific parameters
