Since 1947, Aqua-Chem equipment has produced high-purity water for pharmaceutical applications. Over the past 60 years, we have supplied equipment to hundreds of pharmaceutical and biotech facilities worldwide. Today, we supply Aqua-Chem Spray-Film:emoji: vapor compression distillation units to produce consistent, reliable, high-purity Water for Injection (WFI) for parenteral solutions, cell culture growth, vaccines and other critical applications.
Design Features
Compressors – Low-speed, direct drive compressors are offered Shielding=宋体>– The evaporator features a horizontal design using the Spray-Film:emoji: process. It has a straight tube or U-tube configuration depending Shielding=宋体>– and no large gaskets requiring routine maintenance.
Heat Source – The vapor compression process uses its own compressed steam as its primary heat source, resulting in vastly improved efficiency.
Hot or Cold Distillate – The stills can be designed to produce hot (180° F) distillate, cold (90° F) distillate or both. Output can range from 300 to 7,200 U.S. gph.
Materials of Construction – Standard materials are 316L stainless steel, product contact surfaces are 25 RA, and evaporator tubes are bright annealed. Material certifications are provided for traceability and electropolish is available.
Sanitary Components – Stills are manufactured using sanitary valves, instruments, pumps and piping. Heat exchangers have double tube sheets. Designs include sloped piping and low point drains.
Automation – Stills are designed to operate automatically; stopping and starting based Shielding=宋体>– Our stills can include variable speed to allow turndown to around 50 percent of design flow, allowing the still to match tank drawdown while reducing stops and starts.
Deaerator – A 316L SST deaerator removes carbon dioxide, oxygen and other noncondensable gases from the feedwater or distillate.
Insulation – The evaporator and deaerator are insulated with fiberglass and covered with aluminum cladding. Polished stainless steel cladding is also available.
Benefits
Spray-Film:emoji: vapor compression distillation units produce consistent, reliable, high-purity Water for Injection (WFI) for parenteral solutions, cell culture growth, vaccines and other critical applications.
Patented Spray-Film evaporator design provides improved wetting of the tube bundle and reduced scaling. This means less downtime for cleaning and reduced blowdown for less water waste.
Spray-Film design includes built-in Shielding=top width=81>
