WFI Condensing Unit

Unidad condensadora de WFI de Neopure

The WFI Condensing Unit of Neopure is designed to obtain WFI by condensation of pure steam ensuring a high-quality by monitoring systems (TOC, conductivity, …).

The water for injection is used in the industry as a basis raw material for parenteral products manufacturing. It is used also as a cleaning or rinsing material of critical manufacturing equipment.

Tanks and heat exchangers: AISI-316 L

Pipes, valves and instruments: AISI-316 L

Bench: AISI-304

The main features of the system are:

– Storage tank with all pasts in contact with WFI made of stainless steel AISI-316L and the rest in stainless steel AISI-304. Designed by CIFA to reduce susceptible áreas to contamination, spray ball in the WFI return. Venting filter heated of 0,22µm.

– A pharmaceutical feeding pump, to continuously recirculation of WFI. Its power is monitored by a variable-frequency motor drive that receives a signal from a non-invasive flowmeter in the storage tank return pipe. The flow set point is 1,4 m3/h to maintain a minimum return velocity in the return line of 1 m/s, according FDA recommendation for this kind of facilities.

– Distribution loop made of pharmaceutical pipe, according to ASME BPE standard, with polish SFT1. All the welds are made by an orbital automatic TIC procedure.

– Temperature control system by a heating half-round in the storage tank. This system allows to maintain a stable temperature of 80ºC in normal working conditions and allows increase the temperature to 121ºC to do a thermal sterilization.

– User point valves “zero dead leg” type ensure a complete draining and minimize the microbial contamination risk.

– The control system is based on a Siemens PLC with ET200 architecture and a touch screen of 10” manage the system, select and monitor the parameters. This system only Works under operator password with identification function limits.
