The PURELAB 7000 series is designed for applications requiring higher flows of Type II pure water or as a pure water feed system for small distribution loops. The system can supply water from the internal 50 liter reservoir at varying flow rates or can feed into much larger vessels as required.
  • Small high purity distribution system with variable flow rates
  • Auto rinse and simple sanitization procedures maintain the purity of water for the life of the system

For operating a PURELAB 3000/7000 system, a starter kit 1 or 2 is required.

Failure to comply with the feedwater pretreatment recommendations will affect the life and performance of key components and may invalidate the warranty. Feedwater requirements are specified for units fitted with a Protek L2 pretreatment cartridge. If feedwater purity is variable or values are outside any of the above ranges, additional pretreatment is recommended to be installed in the feedwater supply to the unit.

Deionization cartridge life may vary with feedwater >1400 µS/cm
