DITEC: Water-for-Injection Production

Multiple-effect distillers, or DITEC, are daily employed for Water for Injection production.

DITEC is built with the simplest piping structure possible. This simplified and efficient design aims to reduce energy consumption and to contain microbiological contamination.

Multiple-effect distillers have several consolidated features that make them perfectly efficient and easily applicable in pharma and biotech processes, such as the integral pre-heating coil, which allows an easier design and high thermal efficiency. The falling film feed system with an instantaneous flash evaporation effect to improve evaporation efficiency. The possibility to produce pure steam at first-effect in alternation or while producing CS. The availability to supply automation and control system, mostly based on industrial PLC/HMI interface.

DITEC 6.000/6 is designed and manufactured with six effects, operating capacity 5.000 l/h at 90° with industrial steam at 6 barg. The system is built and wired on skid, equipped with its own control system, all this makes it a stand-alone WFI controllable unit and fully testable during FAT.

It consists of six columns made of AISI 316 L stainless steel, rock wool thermal insulation; high pressure multistage pump; 200L feed tank; two heat exchangers DTS type; valves and sensors; cooling system. 

The control system is based on PLC/HMI solution, with one remote I/O module. The HMI interface allows to supervision system status, manage and monitor automatic production, manage multiple user accounts/groups, monitor and manage alarms, view real-time and stored data and more.

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