What Are the Energy-saving Renovation Methods for Compressed Air Systems?

Compressed air is the blood of modern industry. Its quality and energy efficiency are core factors for our customized selection and solution design. Based on actual on-site demands, we provide tailored energy-saving cooperation solutions for compressed air systems. What are the mainstream energy-saving renovation methods? This article introduces five effective approaches in detail.

• Replace with Energy-saving Equipment

Introduction: Renovate existing air compressors or adopt new high-efficiency equipment, and replace high-power-consumption units with first-class energy-efficiency products.

Typical Application: Upgrade outdated and low-efficiency air compressors to permanent magnet variable frequency two-stage compression air compressors.

Energy-saving Effect: Comprehensive energy-saving rate reaches 30%–50%(Chinese National Standard), realizing fundamental energy consumption reduction.

• Waste Heat Recovery

Introduction: Recycle the excess heat discharged during air compressor operation to meet the factory’s heating demands.

Typical Application: Waste heat recovery system: Supply recovered heat for domestic hot water, boiler water replenishment and workshop heating.

Compression heat regenerative adsorption dryers: Regenerate adsorbents by utilizing compression heat generated by air compression.

Energy-saving Effect: Remarkable energy reduction and significant cutdown on heating power consumption.

• Energy-saving Benefit Sharing

Introduction: Deman launches a win-win cooperation model: Asset-light & High-efficiency Air Supply. Deman fully invests in and provides all equipment, intelligent control and operation & maintenance services. Customers enjoy high-efficiency compressed air with zero or low asset investment and share energy-saving benefits together.

Customer Benefits: Lower investment, outstanding energy-saving performance and sustainable profit sharing.

Benefit Calculation Formula: Energy-saving Revenue = (Original Air-power Ratio − New Air-power Ratio) × Air Consumption × Agreed Average Electricity Price × Sharing Ratio

Parameter Explanation: Original Air-power Ratio: Power consumption per cubic meter of original compressed air

New Air-power Ratio: Power consumption per cubic meter of high-quality compressed air supplied by Deman

• Air Sales Model

Introduction: Deman produces and supplies qualified compressed air to customers at a price lower than the customer’s self-operation cost.

Customer Benefits:

-Zero upfront investment

-Stable and obvious energy-saving effect

-Worry-free air supply, just like using water, electricity and natural gas

Applicable Scenarios: Enterprises focusing on core production and unwilling to invest heavily in compressed air system management and assets.

• Build High-efficiency Compressed Air Stations

Introduction: Deman application engineers design customized systems from six major energy-saving dimensions, delivering compressed air station solutions with the highest comprehensive transmission and operation efficiency.
