Guided by the dual carbon goals, the heavy machinery manufacturing and metal processing industries are facing critical challenges in green transformation. A heavy industry enterprise in Jiangsu actively responded to the call by launching an energy-saving retrofit project for its air compressor systems. After a comprehensive evaluation of various air compressors on the market, Hand's highly efficient, energy-saving, stable, and reliable two-stage permanent magnet screw compressors (HD-EPM2T series) stood out for their outstanding performance. Through in-depth discussions and negotiations, both parties reached a cooperation agreement. Following an on-site assessment by Hand's professional team, four customized two-stage permanent magnet screw compressors were selected for the enterprise: two HD-EPM2T220 units, one HD-EPM2T132 unit, and one HD-EPM2T110 unit. These successfully replaced the existing six outdated units. This intelligent and high-efficiency technological upgrade has increased the enterprise's compressed air production capacity to 140m³ and improved overall energy efficiency by over 20%, ushering in a new chapter of green production.

Why Choose the Hand HD-EPM2T Series?

The company's decision to purchase four new units at once stems from its deep recognition of the core advantages of the Hand HD-EPM2T series. Through multiple innovative technologies, the HD-EPM2T series achieves comprehensive breakthroughs in performance, energy efficiency, and maintenance convenience.

Innovative Design Ensures Long-Term Stable Operation of Equipment

1. Independent Air Inlet and Outlet Channels: Precisely planned airflow paths enable separate air intake for the air filter, motor, and electrical cabinet. This design prevents repeated heat intake within the enclosure at the source, ensuring clean air intake, reducing component wear from high temperatures and impurities, and significantly extending equipment lifespan.

2. Multi-stage High-Efficiency Cooler: Features a segmented structure that substantially reduces stress deformation caused by thermal expansion and contraction, enhancing operational stability. Modular design enables easier disassembly and replacement of the cooler, significantly lowering maintenance complexity and time costs.

3. Oil/Gas Drum Lifting and Rotation Structure: Innovatively integrates all pipelines within the drum body, eliminating pipe fittings on the drum cover to completely resolve the complexity of traditional pipeline connections. Even when handling large machinery, maintenance operations can be easily performed by a single operator.

4. Temperature-Controlled Oil Filter Housing with Flat-Seal Mixed-Flow Design: Effectively avoids stalling failures common in traditional diverter-type piston temperature control valves, eliminating operational risks and providing robust assurance for production continuity.

High Efficiency and Energy Savings: Building Core Competitive Advantages in Cost Reduction and Efficiency Enhancement

5. Full Range of Super-Class 1 Energy Efficiency: Integrating large rotor, low-speed design concepts with two-stage compression technology, achieving high-efficiency operation at low pressure ratios. Overall energy efficiency exceeds national Class 1 standards by 3%-5%, delivering over 20% energy savings and significantly reducing long-term energy costs.

6. Low-Speed Large-Diameter Centrifugal Fan: Featuring a simple and compact structure, its operational efficiency far surpasses traditional fans. While maintaining stable operation, it also offers low-noise advantages. Outstanding heat dissipation ensures the equipment maintains optimal operating temperatures during high-load, extended-duration operation, safeguarding efficient performance.
