OEM 22kW 30HP Variable Speed Rotary Screw Compressor Factories, Exporter
Product Description
Product Overview
The XZV-30A represents a step up in capacity, featuring a 22kW permanent magnet motor that delivers up to 3.7 m³/min at 0.7MPa. This model is engineered for manufacturing facilities with moderate to high air consumption, including multiple production lines operating simultaneously. The advanced VFD technology ensures that the compressor runs only as hard as necessary, dramatically reducing energy waste during low-demand periods. The anti-corona stator winding is a key differentiator—it prevents electrical discharge damage in high-voltage environments, making this unit particularly suitable for facilities with unstable power supply or frequent start-stop cycles. The 1" connector and 396kg robust construction provide a stable, vibration-free operation that extends component life.

FAQ
Q1
What makes the anti-corona stator winding different from standard windings?
Standard motor windings can suffer from corona discharge—a phenomenon where high-voltage electrical fields ionize air around the winding, causing gradual insulation degradation. This leads to shorts and motor failure over time. Our anti-corona winding uses specially coated enameled wire and reinforced slot insulation that prevents this discharge, making the motor suitable for high-frequency VFD operation and areas with unstable power. This is particularly important for compressors that start and stop frequently, as voltage spikes are common during these cycles.
Q2
How does the VFD handle sudden spikes in air demand, such as when multiple machines start simultaneously?
The XZV-30A's VFD has a rapid response time of less than 0.5 seconds to pressure drops. When demand spikes, the drive instantly increases motor speed to supply the required air, preventing pressure dips. Unlike fixed-speed compressors that rely on large storage tanks to buffer demand, the VFD responds dynamically, allowing for a smaller receiver tank (saving floor space). The unit's maximum torque is available from zero speed, ensuring immediate response.
Q3
Can the XZV-30A be paralleled with another compressor for redundancy?
Yes, the PLC supports master/slave sequencing for up to 4 compressors. When connected, the PLC coordinates startup, load sharing, and standby rotation to equalize operating hours across units. This extends the service life of each compressor and provides automatic backup if one unit requires maintenance. The sequence control is fully programmable via the touch screen.
Q4
What is the recommended receiver tank size for this model?
For optimal performance, we recommend a 1,000-liter (1 m³) receiver tank. This provides adequate buffer for demand spikes and allows the VFD to operate efficiently. The tank also helps remove moisture from the compressed air through natural cooling. For critical applications requiring tight pressure control, a 2,000-liter tank is recommended.
Q5
How does the 81°C constant temperature control impact oil life and maintenance costs?
Maintaining oil at a consistent 81°C prevents the two main causes of oil degradation: excessive heat (which oxidizes oil) and condensation (which emulsifies oil with water). By staying at the optimal temperature, the oil maintains its lubricating properties for much longer—typically 6,000 hours between changes compared to 2,000–3,000 hours in traditional compressors. This reduces annual oil costs by approximately 50% and extends the life of bearings and rotors.
