Aquastel
EA-devices are the latest development in onsite production of biocidal
liquids. Aquastel EA-devices
differ from Eurostel EZ-devices as the quality of the produced biocidal
liquids is continuously monitored, controlled and therefore guaranteed. Online pH, ORP and FAC measurements
give feed back to the Siemens S7-200 PLC that adjust e.g. valves and
pumps in order to keep the parameters of the biocidal liquid within
pre-set limits.
These
mobile disinfecting systems include a fully automatic Aquastel EA-device
as well ancillary equipment such as a water-softener, pre-filters, a
well-pump, a pressure reducing valve, a flow-regulator, a
brine-container, an collecting tank for the
biocidal
liquid and other measurement equipment to monitor the quality and
quantity of the produced biocidal liquids.
All
Aquastel EA-devices consist of 2 enclosures to keep electricity and water
separated:
·
The electrical
enclosure contains the Siemens S7-200 PLC, printed circuit boards,
power supply and all other electrical components needed to create a
rectified AC-voltage.
· The hydraulic enclosure
contains e.g. the Electrolytic cell, brine-pumps, acid pump, a
flow-sensor, high/low current detection and various solenoid valves the
parameters of the generated biocidal liquids
· The
operation enclosure is mounted between the electrical and hydraulic
enclosure. The operator only need to access this enclosure in order to
program or operate the Aquastel EZ-device.
The
volume these EA-devices generate can be re-programmed by the operator.
85 - 100% Neutral Electrolyzed Water with a pH
between 6.8 – 8.8, an ORP over 800mV and with 50 to 500 ppm. Free
Available Chlorine. 0 - 15% Alkaline Water with a pH 11-13 and an ORP of
approximately -900mV is generated.
2
models of Aquastel EA–devices are available. EA-100 and an EA-200 device
capable of generating 100 or 200 Liters per hour.
