FilmTech™ Fortilife™ HSRO-4040-FF (Heat Sanitizable)
Updated on October 12, 2025
Key Features:
• Delivers outstanding quality water with the added capability to withstand sanitization with hot water
to eliminate the need for chemical sanitizers.
• High active membrane area that allows system design with either lower operating flux or cost savings
from fewer membrane elements..
• Full-fit configuration design that minimizes stagnant areas for sanitary designs.
Key Application:
• Purified water in the pharmaceutical, medical and biotechnology applications.
• Permeate polishing in food and dairy pro cesses.
