Fact Sheet
E-Cell MK-2 PharmHT
Heat Sanitizable Ultrapure Water for Pharmaceutical Industry
Description and Use
E-Cell* electrodeinization (EDI) technology is setting
the industry standard for chemical-free, ultra-pure
water production. E-cell stacks offer a robust alter-
native to mixed bed technology.
The PharmHT model series is designed to deliver
high purity water for pharmaceutical applications
where heat sanitization is required, rated for 60 cy-
cles of sanitization at 80°C.
The modular design allows configuration of single
or multiple stacks to provide a cost-effective treat-
ment across all flow requirements.
