Description
The design of the unit offers excellent performance for production of water for injection.
Simplicity and efficiency: A group of distillation columns in series designed to evaporate the purified water and condense pure steam. Their design allows the steam water drops, containing impurities, particles and pyrogens to be separated by the effect of gravity. This design has proven to reduce the level of endotoxins by 3 to 4 log.
Fully sanitary design: The exchanger bodies and the separation chambers are electropolished after mechanical polishing, to provide greater resistance to corrosion produced by "rouging". The exchanger pipes, AISI 316 L stainless steel, seamless pipes, in accordance with ASTM 270, are bored (expanded) at both ends, in the double plate, so that they are free from cracks and their useful operating life is extended.
The pipes with active surfaces have been already mechanically polished when they are purchased from the supplier, with a surface roughness of Ra < 0.6 μm. The inline, detachable connections are TC sanitary type (Tri-Clamp), with Gylon® Bio-Pro gaskets (with FDA certification). All welding is carried out in inert gas atmospheres (argon), with automatic orbital welding whenever possible.
Low maintenance: The inside of the pipes is filled with non evaporated water from the previous column. The pipes are always immersed in water, preventing liming. Furthermore, as they are relatively short, they do not dilate or vibrate, minimising leaks. The column gasket is very easy to change. The skid is made out of AISI 304 stainless steel.
Safety and easy operation: Operation is fully automated by means of sensors. The unit has all the required safety and protection equipment, with warning signals and alarms. A PLC performs the control and management of the equipment. The equipment can be easily supervised and controlled by means of a touch screen in the control panel.
