Demineralizer System...produce high purity water

Product Announcement from Res-Kem LLC

 Demineralizer System...produce high purity water -Image

Res-Kem's industrial two-bed deionizers are available as standard pre-engineered units or as custom designed systems with the flexibility to meet a wide range of individual customer requirements.

Ranging in size from 18" to 96" in diameter and with flows from 10 to 220 gpm, Res-Kem's two bed deionizers are a highly efficient means of removing dissolved minerals and solids to produce high purity DI water. Regeneration of the system is initiated by conductivity, time, and/or totalized flow. The deionizers can be supplied in combination with a full range of options and related equipment to provide a fully integrated water purification system.

Res-Kem Dual Bed Deionization Systems are designed for fully or semi-automatic operation. These systems will integrate into a complete water treatment system without expensive custom field engineering and programming.

Why use a Deionized Water System?

High pure water treatment is required in many industries, applications, and processes. Res-Kem offers a series of pre-assembled systems for the production of a continuous supply of high purity deionized water. Some of the many applications for high purity water are in:

  • Food and Beverage Processing Plants
  • Power Plants
  • Chemical Plants
  • Pharmaceutical Plants
  • High pressure boiler feedwater
  • Manufacturing Plants
  • Laboratories
  • Autoclaves
  • Steam Generators
  • Electronic Products
  • Medical Device Production
  • Alloy Metal Fabrication
  • Aerospace
  • Humidification Systems
  • Metal Treating and Plating
  • Printed Circuit Boards


  • Uses Less Water Than a Comparable RO System
  • Materials Selected to Maintain Water Quality and Long Service
  • High Quality Water Despite Changes in Water Flow Rate
  • Standard Designs Reduce Cost, Installation and Delivery Time
  • Simple Operation Reduces Operator Training Requirements


  • Conductivity of less than 10 micro-ohms
  • Flow rates from 10-220 gpm and capacities from 140,000 - 2,200,000 grains
  • Strong acid 8% crosslinked cation and type 2 strong base anion resins as the standard, with other resins available as an option.
  • Microprocessor based control system with conductivity monitor and flow sensor for regeneration initiation.
  • Electrical enclosures are NEMA 4XFG corrosion resistant fiberglass, which reduces maintenance costs.
  • PVC coated steel vessels depending on size and customer requirements.
  • Optional ASME code vessels.
  • Factory assembled and skid mounted for quick installation and minimum startup cost.
  • Schedule 80 PVC piping package including air operated true union ball valves are standard. Air or electric actuated ball or butterfly valves are available as an option.
  • Pressure regulators, rotameters and metering valves supplied for accurate and safe control of regeneration water and chemical introduction.
  • Internal distributors are corrosion resistant, designed for optimum efficiency and are fully supported where required.
