Core Competitive Advantages

Elily’s customized 3–6 bar low-pressure screw compressor delivers ultra-large air volume output, capable of replacing traditional industrial blowers while achieving 30%+ energy savings.

Tailored specifically for medium-and-low pressure, high-flow air demand scenarios, the 75kW permanent magnet VSD low-pressure screw compressor acts as a high-efficiency, energy-saving core power unit. It is widely applied in textiles, glass processing, chemical industry, food and beverage production, and various automated industrial production lines.

1. Extreme Energy Efficiency & Top-Grade Energy Performance

Featuring a directly-coupled permanent magnet synchronous motor with no excitation current loss, the unit reaches IE5 ultra-high energy efficiency grade, over 10% higher than standard asynchronous motors.

Compared with conventional fixed-speed compressors, the comprehensive energy-saving rate ranges from 30% to 50%. For a standard 75kW unit operating under normal production loads, the annual electricity cost savings can exceed 70,000 RMB.

2. Advanced Reliable Motor Technology

The motor is fitted with high-performance NdFeB permanent magnets and adopts a 180°C high-temperature demagnetization-resistant structure, effectively avoiding performance degradation under continuous high-load operation.

Optional air-cooled and oil-cooled dual cooling solutions support stable long-term operation even in harsh industrial environments.

3. Stable Operation & Intelligent Precise Control

Built with SKF heavy-duty bearings and high-rigidity rotors, the compressor operates with low vibration and low noise, ranging from 65 to 75 dB(A).

The standard intelligent VSD control system maintains constant air pressure with fluctuation controlled within ±0.01 MPa. Soft-start technology greatly reduces grid current impact during startup. The integrated intelligent controller supports RS485 remote monitoring and real-time fault early warning, ensuring safe and stable unmanned operation.

4. Humanized Structure & Low Lifecycle Maintenance Cost

Direct-coupled host transmission eliminates coupling power loss, achieving 100% transmission efficiency.

The modular overall structure enables quick disassembly, easy access for daily inspection and convenient maintenance, significantly reducing full-lifecycle operating and maintenance costs for end users.

FAQ

Q1: Are you a factory or trading company?

A: We are a manufacturer based in Dongguan, Guangdong, owning a 20,000 m² production facility. We offer direct factory pricing and full professional technical support.

Q2: Does your factory provide machine trial testing or equipment rental services?

A: We support trial tests and short-term equipment rental subject to project demands. Please contact our sales team to discuss detailed terms.

Q3: What is the OEM lead time, and how do we coordinate OEM orders?

A: We have a specialized technical team dedicated to OEM customization. After confirming your technical scheme, customized drawings will be delivered for your review within 7–15 working days. The full production cycle varies based on customization complexity. Clients may communicate with our engineers directly via phone, email, or on-site factory visits.

Q4: Which brands are your motors and frequency converters equipped with?

A: All units adopt Class 1 high-efficiency permanent magnet synchronous motors matched with Zhongchen split-type inverters. The two components deliver perfect compatibility, rapid response and precise pressure control performance.

Q5: What is the minimum working pressure of the 75kW low-pressure model?

A: Stable operation at 0.3 MPa is standard. Ultra-low pressure output is available by customizing dedicated low-pressure screw air ends.

Q6: Can multiple compressors run in parallel?

A: Yes. Several units can be connected and synchronized under unified control with automatic load balancing.

Q7: Do I need to prepare compressor oil separately for skid-mounted models?

A: The screw compressor is pre-filled with dedicated coolant oil at the factory. On-site trial operation can be carried out right after delivery.

Q8: Can the machine adapt to overseas voltage standards such as 415V or 460V?

A: Custom configurations for non-standard voltages are available. Customization of inverters and electrical parameters will be required.

Q9: What is the largest low-pressure system project you have delivered?

A: We supplied six sets of 75kW skid-mounted low-pressure compressors for parallel operation at a large wastewater treatment plant, achieving a total air flow of over 100 m³/min.
