Compressed Air Solutions for New Energy & Battery Manufacturing

New energy and battery manufacturing facilities rely on compressed air for automation equipment, pneumatic conveying, assembly systems, control valves, production machinery, packaging, maintenance, and general plant utilities.

Some production areas may have relatively standard compressed air requirements, while other processes can be significantly more sensitive to moisture and contamination.

Moisture, oil aerosols, and solid particles in untreated compressed air can affect pneumatic components, production equipment, and process consistency. Where compressed air is used in moisture-sensitive production areas, the required pressure dew point may be substantially lower than that of ordinary plant utility air.

Lingyu provides refrigerated air dryers, regenerative desiccant air dryers, modular adsorption dryers, and multi-stage compressed air filtration solutions for battery and new energy manufacturing facilities requiring stable moisture control and reliable compressed air quality.

Why Air Quality Matters

Compressed air naturally contains water vapor and may also carry oil aerosols and solid particles from the surrounding environment, compressor, piping, and distribution system.

As compressed air cools, water vapor can condense inside pipelines and downstream equipment. In moisture-sensitive manufacturing environments, unstable moisture levels can affect process consistency and increase the risk of condensation in pneumatic systems.

Oil aerosols and solid particles may also accumulate in compressed air piping or reach production equipment if they are not adequately removed.

For battery and new energy manufacturing, compressed air quality should therefore be determined according to the actual production area and point of use.

General plant air, pneumatic automation, precision assembly, and moisture-sensitive process air may require different drying and filtration strategies.

Key Challenges

Moisture-Sensitive Production Areas

Some battery manufacturing processes can require tighter moisture control than ordinary plant compressed air applications.

Where a low pressure dew point is required, regenerative desiccant drying can provide deeper moisture removal than standard refrigerated drying.

Different Air Quality Requirements Across the Plant

A large battery manufacturing facility may include general utility areas, assembly sections, automation systems, testing areas, packaging lines, and more moisture-sensitive production zones.

Applying one air quality specification to the entire plant may lead to unnecessary energy consumption.

A staged or zoned air treatment strategy can provide a more practical solution.

Continuous and High-Throughput Production

Battery and new energy plants may operate multiple shifts or continuously.

Compressed air treatment equipment should therefore provide stable performance, practical maintenance, and sufficient capacity for long operating cycles.

Oil and Particle Control

Moisture removal alone is not sufficient for many production environments.

Oil aerosols and solid particles should also be controlled through appropriate filtration according to compressor type and downstream equipment requirements.

Variable Compressed Air Demand

Compressed air demand may change as production lines, assembly equipment, pneumatic systems, and different shifts start or stop.

Where air demand fluctuates significantly, system capacity and energy control should be considered during dryer selection.

Energy Efficiency

Deep drying requires additional energy and, depending on dryer technology, regeneration air.

The lowest pressure dew point should therefore be applied only where the process actually requires it.

Recommended Solution

For battery and new energy manufacturing, a practical compressed air treatment strategy often combines central moisture removal with dedicated low-dew-point treatment for selected production areas.

For general plant and utility air, a refrigerated air dryer combined with appropriate filtration may provide sufficient moisture control.

For production zones requiring substantially drier compressed air, a regenerative desiccant air dryer can be added as a dedicated low-dew-point treatment stage.

For smaller local systems or equipment-side applications, modular adsorption drying can provide a compact alternative.

The final system should be selected according to total compressed air flow, pressure, inlet temperature, ambient conditions, required pressure dew point, filtration requirement, production area, and duty cycle.

General Plant and Utility Compressed Air

For general pneumatic equipment, automation, conveying, packaging, and plant utility air, the AH Series Air-Cooled Refrigerated Air Dryer provides a practical solution where refrigerated drying meets the actual process requirement.

The AH Series provides:

• Pressure dew point: 2–10°C
• Rated inlet pressure: 0.7 MPa
• Operating pressure range: 0.6–1.0 MPa
• Rated inlet temperature: 50°C
• Maximum inlet temperature: ≤80°C
• Operating ambient temperature: 2–45°C
• Pressure drop: ≤0.025 MPa

This configuration can be used as a central treatment stage for general compressed air users where deep adsorption drying is not required.

Low-Dew-Point Process Air

For moisture-sensitive production areas requiring substantially drier compressed air, the HH Series Heatless Regenerative Desiccant Air Dryer provides a low-dew-point solution.

The HH Series provides:

• Outlet pressure dew point: ≤−40°C
• Rated inlet pressure: 0.7 MPa
• Operating pressure range: 0.6–1.0 MPa
• Rated inlet temperature: 10–30°C
• Maximum inlet temperature: ≤40°C
• Average regeneration air consumption: 8–14%
• Desiccant: Activated Alumina + High-Performance Molecular Sieve
• Operating ambient temperature: 2–45°C

This configuration can be considered for production areas where the actual process specification requires a low and stable pressure dew point.

The required dew point should be confirmed according to the production process rather than assumed from the industry alone.

Compact Low-Dew-Point Treatment

For smaller capacities, local production zones, or installations with limited equipment space, the M Series Modular Heatless Desiccant Air Dryer provides a compact adsorption drying option.

This type of system can be considered for:

• Local low-dew-point compressed air
• Precision assembly areas
• Equipment-side treatment
• Small process zones
• Space-limited technical installations

Final selection should be based on actual air flow, operating pressure, inlet conditions, and required pressure dew point.

Multi-Stage Compressed Air Filtration

Drying controls moisture, while filtration helps reduce oil aerosols and solid particles.

Lingyu D Series compressed air filters provide several filtration grades:

Multiple filter stages can be configured according to compressor type, dryer configuration, production environment, and downstream air quality requirements.

For adsorption drying systems, suitable upstream filtration also helps protect the desiccant from oil and particulate contamination.

Where very low residual oil levels are required, activated carbon filtration can be considered after appropriate upstream treatment.

Staged Drying for Moisture-Sensitive Production

In some battery manufacturing facilities, a staged treatment approach can provide a practical balance between air quality and operating efficiency.

A typical arrangement may include:

Air Compressor → Air Receiver → Refrigerated Air Dryer → Multi-Stage Filtration → General Plant Air

For production areas requiring deeper drying:

Pre-Treated Compressed Air → Regenerative Desiccant Air Dryer → Final Filtration → Low-Dew-Point Process Air

This approach removes a large portion of the moisture before the adsorption dryer, reducing the moisture load on the low-dew-point treatment stage.

It also allows deep drying to be applied only where necessary rather than to the entire plant compressed air system.

Energy-Efficient Low-Dew-Point Systems

For larger battery manufacturing facilities with continuous low-dew-point compressed air demand, regeneration air consumption becomes an important operating consideration.

The HRB-E Series Low-Purge Blower-Heated Regenerative Desiccant Air Dryer provides:

• Outlet pressure dew point: −20°C / −40°C optional
• Regeneration air consumption: 2–3%
• Rated inlet pressure: 0.7 MPa
• Operating pressure range: 0.6–1.0 MPa
• Maximum inlet temperature: ≤40°C
• RS-485 communication as standard

During regeneration, an independent blower supplies heated ambient air to regenerate the desiccant.

Only a small amount of dry product air is used during cooling, reducing compressed air losses compared with conventional heatless regeneration.

For larger continuous-duty installations, this can provide a more energy-conscious low-dew-point solution.

Heat-of-Compression Drying

For suitable compressor and system configurations, a Heat-of-Compression Regenerative Desiccant Air Dryer can also be considered.

This technology uses heat already present in the compressed air system to support desiccant regeneration.

It can be suitable for selected large industrial projects where compressor type, discharge temperature, operating schedule, and required pressure dew point make heat-of-compression regeneration technically appropriate.

Final selection should be based on the complete compressor and air treatment system rather than the dryer alone.

Typical Selection Guide

The final system should be designed according to the air quality requirement of each production area.
