Compact Air Dryers for OEM Integration
Choose a compact compressed air dryer for the air demand of your instrument, machine branch or OEM assembly. XENTRODRY ZLA and DS models cover rated flows from 120 to 500 NL/min.
Use this guide to compare thermoelectric and heatless desiccant drying, then match the model to your pressure, inlet temperature, required dew point and installation space.
Air Dryers Built for Equipment Integration
A dryer can treat the low-flow branch that supplies an instrument or control circuit within a larger machine. Select for that branch’s air demand and quality requirements.
- Compact enclosures for equipment-level installation
- ZLA thermoelectric models: 120, 200 and 400 NL/min
- DS heatless desiccant models: 200 and 500 NL/min
- Check connections, supply voltage, ventilation and condensate drainage before integration
Choose the Right Compact Air Dryer Technology
The ZLA series uses solid-state Peltier cooling to condense moisture from compressed air without a refrigeration compressor or refrigerant circuit. Compare the ZLA compact compressed air dryer models for laboratory instruments, pneumatic controls and equipment-level moisture removal.
The DS series uses twin-tower pressure swing adsorption with heatless regeneration. Compare DS-200 and DS-500 when the application requires a pressure dew point down to −40°C under specified operating conditions. Allow for purge-air consumption when checking the available compressed-air supply.
Common OEM and Industrial Applications
- Laboratory and instrument air: dry air for analyzers, test equipment and pneumatic instruments.
- Automation and OEM integration: moisture control for machine branches, control cabinets and pneumatic components.
- CEMS and gas analysis: distinguish the instrument’s compressed-air supply from its sample-gas stream. For moisture removal from sample gas, compare CS Peltier sample gas coolers.
For selection, provide required flow, operating pressure, ambient and inlet temperatures, target pressure dew point, power supply and available space. The air dryer selection checklist explains these inputs.
Frequently Asked Questions
Is a thermoelectric air dryer the same as a refrigerated air dryer?
Both remove moisture through cooling and condensation. Thermoelectric dryers use a solid-state Peltier module; conventional refrigerated dryers use a refrigeration compressor and refrigerant circuit. Compare the specific model’s flow and drying performance.
When should I choose a heatless desiccant dryer?
Consider desiccant drying when the required pressure dew point is below what a cooling-based dryer can deliver. DS models are specified for pressure dew points down to −40°C under stated operating conditions; include regeneration air in your supply calculation.
Can a compact dryer serve a larger machine?
Yes, when the air demand and operating conditions of the branch being treated match the dryer’s specifications. Overall machine size is not a substitute for checking flow, pressure, temperature and required air quality.
