Applications

Applications for S2 Engineering skid purified plus water systems vary from industry sector to industry sector, but can include;

• Pharmaceutical Water Systems including Purified Water (PW) and Sterile Purified Water (SPW)
• Water for Irrigation
• Sterile Water for Injection (SWFI)
• Water for Irrigation

Technical Features

S2 Engineering Purified Plus water systems are designed to a range of Current Best Practice standards and international specifications. Each governing body (or pharmacopaeias) has its own definition of a purified water system and the corresponding water quality specification. For example,

• US Pharmacopeia (USP): “. . .obtained by a suitable process” so that Conductivity ≤ 1.3 µS/cm @ 25º C, Total Organic Carbon (TOC) ≤ 500 ppb, Microbial ≤ 100 cfu/ml and No endotoxin requirement"
• European Pharmacopeia (EP): “. . .prepared by distillation, by ion exchange, by reverse osmosis or by any other suitable method”
• Japanese Pharmacopeia (JP): “. . .purified by distillation, ion-exchange treatment, ultrafiltration or combination of these methods”

Design Features

S2 Engineering Hot Water modular systems are designed to Current Good Manufacturing Practice (cGMP) and include the following design features.

• Tank and pipework materials of construction for optimum chemical and heat compatibility are typically Stainless Steel (316 or 316L)
• Elastomeric members such as gaskets and diaphragms are typically Teflon, EPDM, Silicone and Viton (FDA approved where required)
• The tanks are designed to be fully drainable (minimum slope 1/8” per foot
• Hygienic tank and system design of components - no bug traps
• Minimize Dead Legs (<= 2 pipe diameters)
• Smooth Surfaces - high mechanical polish/buff
• Mechanically sealed centrifugal Pump or Canned motor pump providing leak tight pumping.
• Gasketed or welded plate heat exchanger providing efficient and quick heat transfer.
• 2 way or 3 Way Globe Control Valve providing accurate temperature control of uid and product.
• Expansion tank to accommodate volume changes expected in thermal fluid.
• Strainers and non return valves for pump and equipment protection.
• Temperature transmitters and Pressure gauges for measurement of operating parameters.
• All electrical components like drive motor, wiring in flameproof construction.
• Seamless pipes and fitting in SS304 or on specific requirement.
• PID or PLC based control system.
• Simple Flameproof Operating Panel or IS HMI as man –machine interface.
• All components are assembled on compact skid to reduce installation and testing time at site.
