Desiccant Dryers

Ultra-Dry Air for Critical Applications — -40°C PDP, Heatless or Heated Regeneration

Key Features

Why This Accessory Matters

01

Dual-Tower Design

One tower dries while the other regenerates, providing continuous -40°C PDP air supply.

02

Heatless or Heated

Heatless (pressure-swing) for simplicity; heated (external blower or internal heater) for energy efficiency.

03

Low Purge Loss

Optimized cycle control reduces purge air consumption to 5–8% of rated flow.

04

Cold Climate Ready

Integral pre-filter, after-filter, and dew point monitoring for reliable sub-zero operation.

FAQ

Frequently Asked Questions

When should I choose a desiccant dryer over a refrigerated dryer?

Choose a desiccant dryer when you need a pressure dew point below +3°C. Typical applications include: outdoor installations in cold climates, lithium battery dry rooms, semiconductor cleanrooms, and pharmaceutical facilities.

How often should I replace the desiccant?

Desiccant typically lasts 3–5 years depending on inlet air quality and operating conditions. Annual purity testing is recommended.
