Puretech - Model OASYS -Chemical Sanitisation System
Puretech’s innovative OASYS is a chemical sanitisation system that provides a single source solution for taking raw water to purified water complying with all relevant pharmacopeia standards. The OASYS has been developed to complement GENESYS™. It is a chemically sanitised version of the GENESYS with a simpler GAMP 4 compliant control system. The unit can be validated up to USP and EP standards with a full FAT being carried out at our works. From softened water to point of use, Puretech’s OASYS offers a true single source, multi-technology validated unit, for producing purified water.
- Purified water to USP, EP and JP
- PLC controlled with touch screen HMI
- Flexible outputs from 100 to 10,000 l/hr
- Condensed footprint with optimal accessibility
- 316L stainless steel pipework
- GAMP compliant
- Validation to regulatory and client standards
- Minimises waste water
- Designed for robust and safe operation
- Flexible system integration, including, UV sanitisation, ultra filtration, TOC Monitor
The design of the equipment offers excellent performance for steam production for use in pharmaceutical production:
Sanitary design: Generator designed in the form of a column, with the heat exchanger at the bottom and the expansion chamber above, which guarantees dry and saturated steam, free from droplets, which fall due to the effect of gravity. The impurities are eliminated or intermittently drained from the bottom of the column.
All the active surfaces are mechanically polished to a surface roughness of Ra < 0.6 μm. The exchanger body is also electro-polished after mechanical polishing. All the detachable connections are joined with Tri-Clamp sanitary accessories, and are supplied with FDA approved quality certificates. All welding is carried out in inert gas atmospheres, using an automatic orbital method whenever possible.
Robustness and reliability: The heat exchanger consists of a double tube sheet (DTS), constructed from AISI 316L stainless steel. The column is thermally insulated with rock wool and it is clad with AISI 304 stainless steel sheet. The skid is made out of AISI 304 stainless steel.
Safety and easy operation: Operation is fully automated by means of sensors and the unit is equipped with the required safety and protection equipment, providing 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.
Quality guarantee: The unit is fully prevalidated in the factory to test its compliance with EN 258 (HTM 2010) standards in terms of saturation, heating and non-condensable gas levels.
Applications
Pure steam is mainly used in the pharmaceutical industry and in biotechnology for:
Sterilization.
Steam is very efficient for sterilizing due to the double effect produced by the heat of condensation (latent heat transfer) and the humidity generated. Wetting results in cellular wall pore opening and heat cell protein coagulation or denaturalization, which is lethal.
Water for injection generation.
When the laboratory requires water for injection but in very small amounts, the installation of a pure steam condensing unit for water for injection production can be beneficial.
Clean room humidification.
Clean steam is sometimes used for clean room humidification by direct injection into the air conditioning system. This theoretically minimises the risk of pollutants entering the production area. The problem with using clean steam for humidifying the air conditioning system of clean rooms is that the clean steam condensate is quite aggressive and may cause corrosion or oxidation in the air conditioning system.
