The POLARIS VCD Solution
1. Pre-heater/Cooler
POLARIS VCD is equipped with Double Tube Sheet heat
exchangers for eliminating contamination risk between
the feed water inlet and the water for injection, whilst
optimising heat recovery from the outgoing WFI and
also from the waste gases produced by the gas removal
device. Polaris VCD integrates the WFI cooling system
producing distilled water between 25°C and 90°C
depending on customer needs.
2. Boiling Chamber
POLARIS VCD can use two different heating sources –
steam and electrical heating – these can be used independently
or combined depending on customer preference.
This system is used to continuously maintain
the operating temperature at boiling point.
3. Core Heat Exchanger
The heat exchanger is the heart of the system where
the balance between condensation and the evaporation
feeds the system with as much energy as is
required to keep the evaporation process ‘alive’.
POLARIS VCD has minimised the energy consumption
thanks to the advanced design of its heat exchanger.
In this process step, gas removal also takes place,
maintaining the optimum WFI conductivity.
4. Water Droplet Separator
This part of the distillation process is responsible for
pyrogen and bacteria removal, the most critical area
of WFI microbiological quality. In POLARIS VCD, the
contaminants are released from the vapour in the
water droplet separator by close control of the shear
and speed ratio between the vapour and any water
droplets present.
5. Vapour Compressor
The vapour compressor increases the pressure and
consequently the temperature of the clean steam.
The purpose of this stage, is to optimise the energy
balance of the distiller. The POLARIS VCD
compressor uses all sanitary components and an
optimised seal design to ensure the highest possible
steam quality. The POLARIS VCD always operates at a
positive pressure differential relative to the surroundings,
making ingress of contaminants impossible.
6. Condensable Gas Separation
The last fraction of contaminant elements is separated
from the steam condensate through WFI re-circulation.
In POLARIS VCD, the re-circulating pump also maintains
the WFI outlet pressure.
7. Automation And Control
POLARIS shares a common control system architecture
and software design with the other VWS Critical
Water Utilities system components, allowing easy
integration for complete Purified Water and WFI systems.
Access to the PLC based control system is via a
colour touch screen HMI. The graphic display screens
are intuitive and easy to navigate. Options include
21 CFR Part 11 compliance and panel mounted PC SCADA.
