Water for Injection systems - How Vapor Compression distiller works

DISTILLATION. THE MAIN WAY TO PRODUCE WATER FOR INJECTION.
These frames from Bram-Cor, Italy, show the process steps of a vapor compression distiller, producing WFI (Water For Injection) for pharmaceutical purposes.
BRAM-COR STMC Vapor Compression Distiller (VCD) produces compendial water for pharmaceutical applications and parenteral preparations, such as LVP, SVP, any injectable product, washing medias and special solutions where both quality factors (such as the sterility, elimination of the pyrogens and of the chlorine solvents with low molecular weight) and economical factors, (low running costs) are critical for the success of the pharmaceutical process.
Each STMC can produce both cold Distillate or hot Distillate with huge savings of energy costs and with no need of cooling water.
BRAM-COR vapor compression distillers operate with electrical heating or plant steam heating or even through both electrical and steam heating systems. Capacities range: from 20 to 20.000 lph with one/more blowers.
The recognized benefits of the BRAM-COR Vapor Compression Distillation technology are :
• Low energy consumption
• No need of cooling water to condensate the pure steam
• No need for high quality inlet water (in some cases even softened water can feed the VC still)
• Very high quality of the WFI thanks to the strong degassying process
• No need to pressurize the inlet water
• WFI outflow at high pressure (1-1.5 bar) without any additional pump
• Extreme safe process, with no risk of any cross contamination through plant steam or inlet water
• Highest flexibility in terms of capacities and WFI temperatures
• Reduced Maintenance
