Polaris™ 2.0

The Polaris™ 2.0 product range features two systems, a skid-mounted multiple effect water distillator (MED) for the production of hot water for injection (WFI), and a skid-mounted pure steam generator (PSG) for the production of pure steam (PS). They guarantee WFI and PS quality in compliance with the European and U.S. Pharmacopoeia, and the produced PS is in line with the European sterilization standard EN285. The range also includes a new validated software for added peace of mind when ensuring compliance with the U.S. Food and Drug Administration (FDA) and Good Automated Manufacturing Practice 5 regulations.

Features two packaged distillation systems that reliably produce hot water for injection and pure steam. To give users peace of mind, they are designed according to European and U.S. Pharmacopoeia and European sterilization standard EN285, and feature validated software to ensure compliance.


At Veolia Water Technologies, we know the availability of pure fluids is crucial for the pharmaceutical and biotech industries when it comes to finished products manufacturing. To meet the needs of our customers, Polaris 2.0 has a robust design and thanks to easy and fast maintenance, it helps to minimize downtime and ensure the availability of high-quality WFI and PS when needed.

How does Polaris 2.0 work?

The Polaris 2.0 range technology is based on high pressure distillation and droplet separation. Sanitization features are available to reduce the risk of microbiological contamination.

The Polaris 2.0 MED is based on high pressure distillation with falling film heat exchange to speed up the preliminary heating phase. The feed water is also used to partially cool down the produced WFI to optimize energy recovery.

The Polaris 2.0 PSG is based on the interconnected water vessels principle where the industrial steam heats up the feed water to the vaporization temperature. A thermal degassing option is available for the compliance with the European sterilization standard EN285.

Both technologies use high-quality stainless steel in the demister for droplet separation.

FAQ about Polaris™ 2.0

Why should I still consider hot WFI production via distillation?

Hot WFI production sensibly decreases the risk of microbiological contamination and biofilm creation. In addition to this, the distillation technology is a very well known process increasing the level of confidence for the end user.

Why should I use an HMI comfort panel instead of a panel PC?

The HMI comfort panel can easily be replaced in case of damage without reconfiguration. Data is saved locally and automatically transferred to your local network. The integration capability of our control platform allows full connection with your network, ensuring a proper data transfer as per FDA CFR21 Part 11.

What is the difference between cold and hot WFI?

The key difference between cold and hot water for WFI lies in the temperature at which the water is produced and maintained.

For example, cold WFI is typically produced and stored at a temperature between 20°C to 25°C and is mostly suitable for applications where there is a need to avoid the potential degradation or alteration of heat-sensitive pharmaceutical compounds. Alternatively, hot WFI is produced and maintained at a temperature above 85°C to 90°C. It is often used for the production plant cleaning in place (CIP) and in processes that require high temperatures to ensure microbial control.

Both cold and hot WFI must meet strict quality and purity standards, including requirements for microbial content, endotoxin levels, conductivity and chemical impurities. The choice between cold and hot WFI depends on the specific requirements of the pharmaceutical or biotech manufacturing process and the characteristics of the products being produced.
