DYS SERIES

Bag & Sock Filter Vessels

Heavy-duty bag filter housings — 15 to 100 GPM — Carbon Steel, 304 SS & 316 SS

The Dynalene DYS Series sock and bag filter vessels are heavy-duty housings engineered for high-flow particulate removal in industrial heat transfer and process fluid systems. Fluid enters the side inlet, passes through the BG Series filter bag supported by an internal stainless steel basket, and exits through the bottom outlet — clean and particulate-free. Available in four sizes in carbon steel or stainless steel with NPT or flanged connections and ASME code stamping upon request.

Specifications

  • Flow rate: 15 to 100 GPM
  • Max temp: 250°F (121°C)
  • Gaskets: Buna-N, Viton®, Teflon®
  • Bag sizes: 1, 2, 3 & 4
  • Stand: Custom tripod leg assembly
  • Pressure rating: 150 PSI
  • MOC: Carbon Steel, 304 SS, 316 SS
  • Connections: 1–4" NPT or flange
  • Basket: 316 SS, 9/64" perforations
  • ASME code stamping available

Features

  • Swing-bolt lid — tool-free bag changeout
  • Side-in / bottom-out or side-in / side-out
  • SS basket protects bags at high ΔP
  • Custom multi-bag housings available

DYC SERIES

Cartridge Filter Vessels

Fine particulate polishing from 0.5 µm — 1 to 100 GPM — 1 to 50 cartridges per vessel

The Dynalene DYC Series cartridge filter vessels deliver precision fine-particle removal down to sub-micron levels. Fluid flows from outside to inside the CD Series depth filter cartridges, with particulates trapped within the cartridge media matrix. Configurable from 1 to 50 cartridges for flows up to 100 GPM, in carbon steel or stainless steel with NPT or flanged connections. Ideal for critical fluid polishing applications where tight particulate control is required.

Specifications

  • Flow rate: 1 to 100 GPM
  • Cartridge count: 1 to 50 per vessel
  • Micron ratings (CD Series): 0.5–200 µm
  • Gaskets: Buna-N, Viton®, Teflon®
  • Stand: Custom tripod leg assembly
  • Pressure rating: 150 PSI
  • Cartridge lengths: 10, 20, 30, 40 inch
  • MOC: Carbon Steel, 304 SS, 316 SS
  • Connections: 1–4" NPT or flange
  • ASME code stamping available

Features

  • Sub-micron filtration to 0.5 µm

Where It Works

Applications

Dynalene filtration systems protect any closed-loop fluid system where solid particulates accumulate and risk damaging pumps, valves, heat exchangers, and fluid integrity.

Heat Transfer Fluid Loops

Removes particulate contamination from glycol-water, hydrocarbon, and silicone HTF closed loops — preventing pump wear, heat exchanger fouling, and valve erosion in industrial process temperature control systems.

DYS / DYC Series

EV & Battery Cooling Systems

Filters particulates from battery thermal management (BTMS) coolant loops — protecting sensitive cooling plates, connectors, and electronics from abrasive contamination in high-voltage EV systems.

DYC Series

Data Center Liquid Cooling

Maintains fluid purity in direct liquid cooling (DLC) and CDU loops for AI and HPC infrastructure — preventing micro-particle deposits on cold plates and manifold blockages in high-density server cooling systems.

DYC Series

Industrial Process Cooling

Filters glycol-water, potassium formate, and hydrocarbon process fluids in manufacturing, chemical, and food-grade cooling loops — meeting process cleanliness requirements and protecting heat exchanger surfaces.

DYS / DYC Series

Fluid Polishing & Reconditioning

Removes solid degradation byproducts, corrosion particles, and scale from aged heat transfer fluids — restoring fluid clarity and extending fluid service life without a full drain-and-recharge.

DYS / DYC / BG Series

Semiconductor & Lab Systems

Provides sub-micron particle control for precision cooling in semiconductor fabs, laser systems, and laboratory equipment — where particulate contamination causes immediate process yield loss.
