Application Scenarios

- High-Precision Manufacturing: Precision painting, electronics assembly, instrument control, and other industries requiring high air pressure stability.
- Continuous Operation Scenarios: Automotive manufacturing, chemical fiber textiles, and other production lines operating 24/7. 
- Harsh Working Conditions: High-dust environments like foundries and building materials plants; high-humidity environments like seafood processing and breweries.
- Energy Saving Retrofit Projects: Replacing traditional high-energy-consumption fixed-speed units for fast payback on investment.
- Space-Constrained Locations: Underground parking garages, equipment mezzanines, mobile air compressor stations.

Customer Frequently Asked Questions (FAQ)

Q1: How reliable is the oil-cooled motor? Is there a risk of oil leakage?

A: The oil cooling circuit utilizes double seal design and pressure balance technology. The cooling oil is synthetic oil with excellent insulating properties. The system features real-time oil pressure and leakage detection. The risk of oil leakage is significantly lower than traditional oil systems, meeting the highest industrial safety standards.

 

Q2: What is the practical value of the IP65 protection rating?

A: IP65 means complete dust-tight and protected against water jets. In high-dust workshops, it prevents overheating failures caused by dust accumulation on the motor. In humid environments or food/pharmaceutical workshops requiring regular wash-downs, it significantly reduces maintenance costs.

 

Q3: Compared to traditional Air Cooled VSD units, what are the specific energy saving advantages?

A: 1) Motor efficiency increased by 5-10%; 2) Oil-Cooled technology keeps the motor at its optimal operating temperature, eliminating high-temperature efficiency loss; 3) Standby power consumption reduced to below 15% of rated power; 4) Integrated design reduces Pressure Drop in piping, improving system efficiency by 3-5%.

 

Q4: Can single-stage compression meet high pressure requirements?

A: The PSO Series is optimized for common pressure ranges (7-13 bar). Within this range, single-stage compression offers the highest efficiency and best reliability. For requirements above 16 bar, we recommend our dedicated high-pressure series.

 

Q5: How is data security ensured on the intelligent cloud platform?

A: We employ a multi-layered security architecture including end-to-end encryption, dynamic token authentication, and physical isolation. Customers control data upload permissions, and on-premise deployment is supported, complying with Level 3 industrial information security standards.
