Vapor Compression Still

The Vapor Compression Still (VCS) produces distilled water for injectable use or WFI, compliant with the requirements of the International Pharmacopeias including USP, EP and JP.

Our VCS is available in two different versions, leveraging different technologies: falling film or rising film, depending on process needs.

Our VCS technology is the result of  decades of experience and continuous technical improvement. It offers two variations: rising film and falling film. The rising film VCS showcases our expertise in distillation, with ongoing refinements to ensure exceptional performance. On the other hand, the falling film VCS represents the cutting-edge solution in VMC technology, placing special emphasis on sustainability, particularly in energy and water conservation. This version stands as the pinnacle of our 50-year journey in mastering falling film heat transfer.

Product benefits
The next generation Vapor Compressor Still

Stilmas’ VCS is able to generate from 100 to 24.000 liters per hour of hot or ambient WFI. The variable wide range of production capacities allows the user to dial in required flowrates.

The Science of Possibility
Electric version available VCS is available in steam-heated or full electric version (plug-in). An hybrid version is also available, for a wider flexibility in the heating source.
The Science of Possibility
Falling Film heat transfer The system works with a small quantity of water inside the evaporation column (90%) compared the traditional configuration, granting 65% less starting time. No hot stand by required allowing less energy consumption.
The Science of Possibility
IIoT READY through MDP (Masco Digital Platform) Digital platform helps to minimize utilities consumption and maximize efficiency. Energy Pack also available.

Technical description

 

Stilmas' VCS (Vapor Compression Still) accepts softened water that through a set of exchangers for energy recovery enters in the main column where it evaporates. The steam, decontaminated through different techniques, is subsequently compressed by a sanitary compressor and released in the condenser where it condensates and becomes WFI.

Reduced Operating Costs
  • Self-modulating system adapts the production flow rate to the storage tank level to minimize water consumption due to start/stop transient.
  • Due to low operating temperature, no cooling water is required and very raw water could be used (at least softened type) 
  • The system features a sophisticated and efficient energy recovery mode developed through pinch technology.
  • To further improve water efficiencies, during low demand each system automatically adjust the blow down to minimize the water consumption
  • Falling film version works with a small quantity of water inside the evaporation column, 90% less, compared the traditional configuration thus allowing 65% less starting time
  • With Falling Film version No hot stand-by required allowing less energy consumption.
