MULTIPLE EFFEC T DISTILLED WATER STILLS ENGINEERING SUCCESS THROUGH FIVE DECADES Pharmalab India Pvt. Ltd. is a leading Engineering Company, with a reputation for designing, manufacturing, erecting and commissioning a variety of fabricated stainless steel process and packaging equipments. We have earned the trust of many major pharmaceutical, biotech, food & beverage, cosmetics and agro-chemical companies over the past 5 decades and currently serve their requirements through three manufacturing facilities. MULTIPLE EFFECT DISTILLED WATER STILL Over the last 25 years Pharmalab has been a leading supplier of plants producing water for injection, which meets international standards, including USP, IP, BP and JP. The plants are manufactured as per FDA- current Good Manufacturing Practices (cGMP) and ASME requirements and follow the basic principle of Distillation by Thin Film Evaporation. This process involves a shell and tube heat exchangers (columns) where heat transfer is done by falling film evaporation. Very high temperatures are reached for every drop of water produced, thus ensuring sterility levels demanded for WFI. Separation of the Pyrogenic load is achieved through centrifugal forces generated during the upward movement of the steam. During the process the feed and distilled water within the plant is in constant motion and hence there is no stagnancy. Impurities, along with the Pyrogenic load, are continuously purged from the last column. At start-up during pre-heating and self sanitizing the residual accumulated water will also drain off before WFI is produced. Our plant is designed to be crevice-free as crevices promote stagnation and stimulate bacterial growth. All columns are designed to ASME specifications and are approved by CE for PED regulations as per European Union requirements. All parts in the plant coming into contact with WFI and Pure Steam are electro polished, pipe joints are orbitally welded, gaskets are made from pure Teflon or pharmaceutical-grade silicon and the first column is double tube sheet designed to prevent pure steam mixing with plant steam, should there be a weld joint failure in the tube sheet. This state-of-the-art system delivers WFI of a quality standard for storage and distribution that is much higher than what is desired by pharmacopoeias throughout the world. UNIQUE PYROGEN SEPARATION AND REMOVAL SYSTEM Pharmalab’s Multiple Effect Distilled Water Still has a unique three-stage pyrogen removal system, which includes a specially designed centrifugal separation followed by separators. We have evolved a rationale for the removal of impure water by the means of a unique purging system. This ensures endotoxin removal exceeding Log 3 reduction.

Factory Acceptance Test (FAT Area) Pyrogen Testing Kit COMBO UNITS ( COMBINED PSG & WFI DISTILLATION UNIT ) A combined pure steam and distillation unit simplifies the production of ultra-pure media WFI and Pure steam. Instead of using two units, Pure steam and Water for Injection (WFI) can be generated with COMBO units in a single unit. This is made possible by the use of a specially designed first column with a larger surface area with the Falling film technique. The Combo units can produce the rated capacity of WFI or Pure steam, one at a time. The capacity of pure steam to WFI can be adjusted to match individual project requirements. Customer-specific versions with higher outputs and with individual configurations are available. Reduced investment cost & Less footprint: Since the COMBO units produce two ultra-pure media, both WFI and Pure steam from a single unit, the investment costs for the system and its periphery are reduced by up to 30 per cent, and the combined unit requires considerably less space than two separate units. Combo distillation unit skids are equipped with NCGR along with fully automatic control panel. The operating mode can be selected either to Pure steam or WFI . The NCGR will assure the non-condensable gas removal during the PSG mode, to meet the EN 285 / HTM2010 quality steam. Fully automatic production of the distillate guarantees USP grade WFI. Online printer can document production and process data in both operating mode.
