Whether you need to maintain ultra-low conductivity, remove specific contaminants, or generate high-purity DI water, Dynalene has an ion exchange solution — backed by 30+ years of heat transfer fluid expertise.

IC Series

Low Conductivity Ion Exchange Cartridges

Maintains electrical conductivity <5 µS/cm in glycol-water coolants and heat transfer fluids

The IC Series mixed-bed ion exchange cartridges contain high-capacity resin media that captures ionic contaminants (Na⁺, Ca²⁺, Mg²⁺, Cl⁻, SO₄²⁻) as coolant flows through, preventing electrical conductivity rise that can cause leakage currents, corrosion, and equipment damage. Compatible with low-conductivity glycol-water blends and Dynalene heat transfer coolant products. Available in six sizes with FNPT or barbed connections.

Features

  • Target conductivity: <5 µS/cm
  • Max temp: 93°C / 200°F (continuous: 85°C)
  • Max pressure: 50–60 psi
  • 0.25" or 0.5" FNPT; barbed options
  • Target conductivity: <5 µS/cm
  • Max temp: 93°C / 200°F (continuous: 85°C)
  • Max pressure: 50–60 psi
  • 0.25" or 0.5" FNPT; barbed options

Applications

  • EV battery thermal management (BTMS)
  • Data center / CDU liquid cooling
  • Industrial HTF closed loops
  • Hydrogen / fuel cell cooling
  • Electronics & laser cooling
  • Custom designs available

CR Series

Contamination Removal Ion Exchange Cartridges

Selectively removes specific ionic contaminants from process fluids and coolants

The CR Series uses targeted ion exchange resin formulations to remove specific contaminants — heavy metals, anions, or cations — without full demineralization. Ideal for industrial HTF loops, process cooling systems, and applications where selective ion removal is required to restore fluid specification compliance. Compatible with water-based and glycol-based fluids.

Features

  • Selective ion targeting (no full DI)
  • Removes: Mo, Se, As, Pb, Ni, V, heavy metals
  • Max temp: 90°C · Max pressure: 40 psi
  • Removes: Cl⁻, SO₄²⁻, Ca²⁺, Mg²⁺
  • Compatible: water & glycol-based fluids
  • Custom configurations available

Applications

  • Industrial HTF & process cooling loops
  • Wastewater & effluent treatment
  • Coolant with corrosion inhibitor contamination
  • Semiconductor & lab water treatment

DYI Series

Laboratory & Industrial Scale Deionization Systems

Provides maximum ion removal in water — from 1 to 40 GPM for medical, food processing, chemical and semiconductor applications

Dynalene DYI series deionization systems are designed and tested for maximum ion removal in water, ranging from small laboratory scale (1–10 GPM) to large industrial scale applications (up to 40 GPM). These systems are easy to install, can be wall-mounted or bought with a stand, and are ideal for making DI water on-site to be blended with glycol to make a glycol-water solution.

Features

  • Output: 1 to 40 GPM capabilities
  • DYI-44: 5 GPM output, 4 cartridge housing
  • TDS meter can be added (optional)
  • High capacity media for long operating cycles
  • DYI-22: 1.3 GPM output, requires two cartridges
  • Polypropylene housing, optional stand
  • DYI-20 cartridges sold separately

Applications

  • Medical applications
  • Chemical manufacturing
  • DI water making for glycol dilution
  • Food processing
  • Semiconductor facilities
  • Industrial system flushing

Where It Works

Applications

Dynalene ion exchange cartridges are engineered for any closed-loop thermal system where ionic contamination raises electrical conductivity and risks equipment damage.

EV Battery Cooling (BTMS)

Maintains low electrical conductivity in battery thermal management loops. High-voltage EV systems (400V/800V) require coolant conductivity <5 µS/cm to prevent leakage currents and protect electronics.

IC Series

H

Hydrogen / Fuel Cell Cooling

Dynalene FC coolant paired with IC Series cartridges delivers a validated, matched fluid-filter solution for PEM fuel cell cooling loops requiring conductivity <1 µS/cm.

IC Series

30+

Data Center / CDU Cooling

Maintains low electrical conductivity in battery thermal management loops. High-voltage EV systems (400V/800V) require coolant conductivity <5 µS/cm to prevent leakage currents and protect electronics.

IC Series

Electronics & Laser Cooling

Keeps deionized or low-conductivity glycol coolants clean in precision electronics cooling, laser chiller loops, and computer cooling systems where conductivity spikes cause immediate equipment failure

IC Series

Contamination Removal

Selectively removes specific ionic contaminants — chlorides, sulfates, heavy metals (Mo, Se, As), and calcium/magnesium — from industrial process fluids and coolants.

CR Series

Deionization & Water Prep

Creates high-purity deionized water on-site for medical, semiconductor, and food processing applications, or for proper dilution of glycol heat transfer fluids.
