Domnick Hunter - Pneudri Air Dryer

• Used in manufacturing facilities to remove moisture from compressed air systems, preventing corrosion and damage to pneumatic tools.
• Essential in food and beverage processing for maintaining dry air in packaging and conveying lines, ensuring product quality and safety.
• Applied in pharmaceutical production to provide clean, dry air for critical processes, avoiding contamination and maintaining sterile environments.
• Utilised in chemical plants to protect sensitive instruments and processes from moisture-related issues, enhancing operational reliability.

Typical capacity

For this class of equipment, capacities commonly range from 100 to 2000 SCFM (Standard Cubic Feet per Minute), depending on the model series.

Power supply

Units of this type typically operate on standard industrial electrical supplies, commonly 230V or 400V, 3-phase, 50Hz.

Dew point achieved

Pneudri air dryers are designed to achieve pressure dew points typically in the range of -40°C to -70°C, suitable for critical applications.

Regeneration method

These units commonly employ heatless or heated desiccant regeneration methods, utilising a portion of the dried air or an external heat source.

Footprint

The physical footprint for a Pneudri air dryer can vary significantly but is typically compact for its capacity, requiring adequate space for maintenance access.

Inlet air pressure

Commonly designed to operate with inlet air pressures ranging from 4 to 16 barg (approximately 60 to 230 psig).

• What is the primary function of a Pneudri Air Dryer?

  Its primary function is to remove water vapour from compressed air, preventing condensation, corrosion, and damage to downstream equipment and processes.

• How does a desiccant air dryer like the Pneudri work?

• What maintenance is typically required for a used Pneudri Air Dryer?

• Can this unit be integrated into an existing compressed air system?

• What are the benefits of using a desiccant dryer over a refrigerated dryer?

Heating and drying equipment for food processing is valued for consistent performance and long operational life when properly maintained. Buyers typically prioritise units with robust construction, reliable temperature controls, and documented maintenance history. Common strengths include energy efficiency and compatibility with existing production lines. When purchasing used models, inspectors should verify heating elements function reliably, check for corrosion or wear affecting interior chambers, and confirm all temperature gauges read accurately. Equipment from reputable manufacturers generally commands confidence in the second-hand market.
