DITEC: Water-for-Injection Production

Description

Data and Design
Service and Support

Our water distillers belong to the latest generation of multi-effect distillers. These automatic systems reliably produce pyrogen-free and high-quality Water For Injection. Our 3D modelling software-aided designs are constantly updated according to the latest heat transfer technology. Distillation columns comply to ASME International rules and PED rules, including other design procedures requested by specific countries.

Principles of operation
The distillation process consists of water steaming, followed by steam condensation, to eliminate the most volatile or non-volatile impurities at water’s boiling point. The multi-effect distillation process includes several ‘effects’, in which evaporation and condensation usually occur at the same time. Feed water evaporates in columns consisting of tube condensers and decontamination chambers, which are joined by a flange connection, and have differing pressures and a decreasing temperature. The first effect is fed by an external heat source; in the subsequent effects this energy is totally reused and is therefore energetically self-sufficient. There are generally 3 to 7 effects included. An increasing number of effects reduces operative costs thanks to a greater percentage of recovered energy as compared to the initial energy fed in the first effect.

DITEC application
The fine chemical, biotechnology, and pharmaceutical industries need to reliably produce water for injection. Our range of multi-effect distillers (DITEC) has been designed to produce Water for injection (WFI) according to cGMP good manufacturing standards in compliance with the European Pharmacopeia and USP guidelines.

Integral pre-heating coil, a new design due to lengthy research and experience
Falling film feed system with an instantaneous flash evaporation effect to improve evaporation efficiency
Water droplet separation based on a combination of multiple physical factors
Pure steam production at first effect in alternation, or while producing CS
Automation and control: the system is controlled by industrial PLC based on HMI interface
