sunsep™, an Alternative to Nafion™ Dryers & Humidifiers

A practical, fact-based starting point for customers evaluating membrane-based moisture control for gas streams. We supply and support sunsep™ fluoropolymer hollow-fiber membrane modules and assemblies.

Quick summary

  • Both are membrane-based approaches used to manage moisture in gas streams.
  • Results depend on sizing, operating conditions, and how the system is configured (including any purge/sweep stream).
  • If you share your current model/length and conditions, we can recommend a sunsep™ configuration to evaluate.

What it is Module format (hollow-fiber). Multiple families and packages depending on application. Tubing-based membrane dryers offered in different lengths/diameters and integrated assemblies.
Moisture control principle Selective moisture transport across a membrane (configuration dependent). Selective moisture transport through Nafion® membrane tubing (configuration dependent).
Purge / sweep stream Often used with a dry purge/sweep stream; the amount depends on the target and conditions. Often used with a dry purge/sweep stream; the amount depends on the target and conditions.
Power requirement Typically passive (no electrical power) for many dryer configurations. Typically passive (no electrical power) for many dryer configurations.
Form factor / integration Module formats that can be packaged for cabinet, rack, OEM, or point-of-use assemblies (depends on family). Often integrated as tubing assemblies; packaging varies by series and supplier.
How we help Selection support, fitting options, and quotes for sunsep™ configurations. If you share your current model, we can help you evaluate a sunsep™ option to trial.

Note: This table is intentionally high-level. For performance targets (dew point, moisture capacity, purge ratios), confirm using formal specifications for your operating conditions.

Common tubing pain points (and how we help)

When customers evaluate a Nafion® alternative, the issue is often less about the membrane material and more about real-world integration: routing, bend radius, fittings, and leak paths. Brink Innovation helps spec a robust moisture-control setup and reduce installation risk.

Kinks / tight routing In some enclosures, tight bends and routing constraints can create flow restriction or installation challenges. We’ll recommend practical routing and packaging approaches for your space.
Leaks at connections Any sample system can leak at fittings or transitions. We help select adapters, end connections, and assemblies to minimize leak paths and simplify installation.
Service time & downtime Moisture-related issues often show up as drift, condensation, and unplanned service events. We focus on moisture stabilization configurations that are straightforward to maintain.
Fast sizing support Share flow, pressure, temperature, and target dew point. We typically respond within 1 business day with a recommended configuration and quote.
What we need to recommend the right setup
  • Flow (L/min) and pressure (psig)
  • Inlet temperature (°C) and target atmospheric dew point (°C)
  • Line length / enclosure constraints (routing and bend radius)
  • Fittings and end connections (e.g., 1/4" Swagelok®, KF, NPT)
