Frequently Asked Questions
Q
What makes the EHV/HV series different from standard screw compressors?
The EHV/HV series features a purpose-built high-pressure dedicated air-end with an optimized rotor profile and 8-bearing design, enabling reliable operation at discharge pressures up to 1.6 MPa. Standard screw compressors are typically designed for lower pressure ranges and cannot match this level of stability and internal sealing performance.
Q
What is the maximum ambient temperature these compressors can operate in?
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, making it well-suited for harsh industrial environments such as foundries, chemical plants, and outdoor installations in tropical climates.
Q
How does the IE5 oil-cooled motor contribute to energy savings?
The IE5 oil-cooled permanent-magnet motor maintains high efficiency across a wide variable-frequency range of 20%–110%, with efficiency fluctuation below 4%. This means the compressor delivers maximum energy savings whether running at full load or partial load, significantly reducing electricity costs over its lifecycle.
Q
What dew point can the built-in air dryer achieve?
The high-efficiency aluminum-plate air dryer uses R410a refrigerant and a high-efficiency heat exchange design to consistently deliver a stable outlet dew point of 2–10 °C. The 5 °C inlet-outlet pre-cooling stage further reduces power consumption and prevents secondary condensation in downstream pipework.
Q
Why is stainless steel piping used instead of standard carbon steel?
SUS304 stainless steel piping offers a smooth interior surface that minimizes pressure drop and is highly resistant to corrosion and rust. This ensures the compressed air remains clean and free from contamination, which is critical for applications in food processing, pharmaceuticals, electronics, and other industries requiring high air purity.
Q
Which model should I choose for a high-pressure application requiring 3.6 m³/min at 1.6 MPa?
For a requirement of 3.6 m³/min free air delivery at 1.6 MPa discharge pressure, the HV 37e-16 (37 kW) is the recommended model. It provides exactly 3.6 m³/min FAD and has external dimensions of 1232×890×1200 mm with a unit weight of 585 kg, connected via a G1 1/2 piping connection.
