Computer-Aided Design for Desiccant Bags & Cartridges

At Flow Dry, we innovate by design and work closely with our clients and stakeholders to deliver moisture and contaminant control solutions including desiccant bags and cartridges. We understand how important it is to you to be able to engage with our engineers early in the design process which is why we offer a full CAD Design service so that you can make the most of our world-leading expertise.

  • AutoDesk Inventor Series which includes AutoCAD, Autodesk Inventor Suite including Autodesk Inventor (3D Design and Modeling), AutoCAD (2D) and 3D Studio Max
  • Solid models for desiccant bags and desiccant cartridges
  • Flow Dry can export data in many different formats including DXF, DWG, IGES, BMP, and PDF
  • Drawings can be sent via secure email or made available via various cloud-based applications or posted to Flow Dry’s secure FTP site. Alternatively, contact Flow Dry to coordinate the FTP process.

Prototype Laboratory for Custom Desiccant Solutions

Flow Dry has an industrial prototype lab where we fabricate hundreds of different styles of prototype and sample desiccant products every year.

When you need a prototype for your flow control, moisture control, or contaminant removal problem then we can provide a cost-effective and rapid turnaround prototype. Working with our engineering experts also means you get design help and access to our dedicated desiccant solutions testing facility.

Industrial Testing of Desiccant Bags & Cartridges

Flow Dry has the capability to test pressure drop, seam strength, vibration, permeability and loss on ignition (LOI) on all its desiccant products to ensure premier quality and reliability.

Pressure drop testing is used to determine the amount of fluid flow restriction a receiver dryer or accumulator design creates. Less restrictive designs have the potential to create a higher performance a/c system. The desiccant package contained inside the receiver dryer or accumulator can create a restriction in the system and therefore increase the pressure drop of the system.

Because pressure drop is a critical design requirement, Flow Dry utilizes a pressure drop tests to aid in designing the highest performance desiccant packages on the market.

The wide range of applications for our desiccant beads means that they may be subjected to great compression forces. Our desiccant beads are tested to a very high standard to ensure they resist fracture and fail during transit and application.

The physical properties of the material used to fabricate desiccant bags are critical to insure proper performance. The permeability of the bag material must be balanced to allow the desiccant exposure to the refrigerant, while at the same time containing any attrition of desiccant particles inside the bag. Because of its low cost and permeability properties, polyester felts have become the standard materials of construction for most a/c desiccant bags.

Some desiccant bag fabricators form or stretch the bag material in the process of manufacturing; this distortion can weaken the material and change its permeability properties. Flow Dry fabricates its desiccant bags without stretching or forming the bag material to insure that the proper permeability rating is maintained. Extensive permeability testing is performed to insure all bags have the proper permeability rating.

Vibration Testing

Vibration testing is used to determine if a desiccant package is designed to withstand the punishment it will be subjected to in a vehicle. If the desiccant package is not designed properly it could be damaged or cause damage to other components in the system. Flow Dry has the capability to test desiccant packages as installed in receiver dryers and accumulators to ensure long life without premature failure.

The industry-standard test to measure the amount of water that has been absorbed by the desiccant is the Loss on Ignition test. To perform this test the desiccant must be heated for a specified period of time to bake out the water. The difference in the desiccant weight before and after heating is the amount of water the desiccant contained. LOI testing is performed on all incoming desiccant material; in-process packaging and outgoing product to ensure the moisture content is maintained at specified levels.

Along with vibration testing, seam strength testing is critical to insure structural integrity of the desiccant package. An automated pull tester checks the strength of package welds. SPC data of the seam strengths is recorded and monitored to insure proper process control.

The Flow-Dry desiccant bag design and manufacturing process retains the highest material integrity and does NOT “stretch” or “deform” the felt material. The Flow-Dry process results in a bag with greater filtering capability and NO “pin-holes” in the material. These holes have led to desiccant and particulate escaping from competitors’ bags and causing damage to a/c systems.
