WFI Production by Distillation Method

WFI Distillation: Energy-efficient, durable, economical

Our distillation systems produce WFI using evaporation columns in a natural circulation process. In multiple evaporation columns, water is first evaporated via heat exchangers and then rises at low speeds to ensure safe droplet separation. During the condensation of the pure steam, WFI is produced. In addition to its use for WFI production, part of the produced pure steam from the first column can be extracted and directly fed into the pure steam network (Twin systems for WFI and PS).

Easy Maintenance and Service

All heat exchangers are located outside the pressure columns and are designed as DTS or simple tube bundle heat exchangers. This design principle ensures easy and reliable maintenance and service of our systems. The production capacity and energy efficiency can be further enhanced by connecting up to seven evaporation columns in series, allowing for flexible adaptation to different production requirements.

Anti-Rouging-Concept

To comply with DIN EN 285, CO₂ and other non-condensable gases are removed from the water through thermal degassing. This process not only improves water quality but also reduces the risk of rouging, a typical surface discoloration on stainless steel components. In this way, our systems contribute to extending the lifespan of the plant and ensuring adherence to the highest hygiene and quality standards in production.

Efficient standby operation with full microbiological safety

Reducing the temperature in the pressure columns to 80–90°C during standby phases ensures quick reactivation while maintaining microbiological safety. This offers energy advantages during the operation of the distillation systems, as well as minimal thermal stress during heating, cooling, and production.
