Frequently Asked Questions
Q
What makes the EHV/HV series suitable for high-pressure applications?
The EHV/HV series features a purpose-built high-pressure dedicated air-end with an optimized rotor profile that minimizes internal leakage. Combined with an 8-bearing design, it delivers exceptional mechanical stability and precision, making it highly reliable for continuous high-pressure compression up to 1.6 MPa.
Q
What is the maximum ambient operating temperature for these compressors?
Thanks to the oversized cooling system with over 25% surplus cooling capacity, the EHV/HV series can operate reliably in ambient temperatures up to 46°C. This makes them well-suited for demanding industrial environments where heat is a significant challenge.
Q
How does the IE5 oil-cooled motor contribute to energy efficiency?
The IE5 oil-cooled permanent-magnet motor offers outstanding efficiency across a wide variable frequency range of 20%–110%, with efficiency fluctuation kept below 4%. Combined with an advanced inverter and intelligent control algorithms, it ensures precise pressure regulation and maximum energy savings under varying load conditions.
Q
What dew point performance can I expect from the built-in air dryer?
The high-efficiency aluminum-plate air dryer uses R410a refrigerant and a high-performance heat exchange design to consistently deliver a stable dew point of 2–10°C at the outlet. The 5°C inlet-outlet pre-cooling design also helps reduce power consumption and prevent secondary condensation.
Q
Why is stainless steel piping used in these compressors?
SUS304 stainless steel piping is used to minimize pressure drop thanks to its smooth interior surface, and to provide high corrosion resistance. This prevents rust contamination, ensures premium compressed air quality, and extends the overall service life of the system with minimal maintenance requirements.
Q
What is the difference between the EHV and HV series models?
Both the EHV and HV series share the same core high-pressure technology, including the dedicated air-end, IE5 motor, and intelligent control system. The EHV series features larger external dimensions and higher unit weight, indicating a heavier-duty all-in-one integrated design, while the HV series is more compact, making it suitable for space-constrained installations with equivalent power and pressure ratings.
