Remote Monitoring
Allows remote monitoring of the air compressor's equipment status and operating data via computer, mobile phone, or tablet;
Authority Management
Allows hierarchical access control for air compressor equipment data and information;
Remote Troubleshooting
Analyzes fault information to help narrow down the problem scope, facilitates advance solution preparation, and saves labor costs;
High-Performance Host
The host utilizes the most advanced manufacturing technology from a renowned German brand.
The host is durable: the screw rotor undergoes special heat treatment and is paired with SKF heavy-duty bearings.
The host offers reliable transmission: the host and motor are elastically connected, resulting in low noise, high transmission efficiency, and no easily damaged parts.
High-efficiency permanent magnet variable frequency motor:
Wide speed range, low noise, compact structure, small size, and light weight; high starting torque.
Made of rigid metal tubingUses metal hard piping materialNot prone to corrosion, ensuring a longer service life.
Adopting a shell-and-tube combined cooler;No internal corrosion, small size, and significant cooling effect.
Fault Reminder Function
When the air compressor malfunctions, it notifies relevant personnel of the fault type and cause in real time via SMS, email, and system messages;
Maintenance Service
Provides maintenance reminders based on different maintenance components and urgency levels;
Employing a fully intelligent computer control system:
A large color touchscreen provides a clear and intuitive interface for system processes and status updates, offering easy and intelligent operation.
A multi-point PLC control and monitoring system, combined with the inverter's PID control system, provides comprehensive and intelligent control, protection, and energy-saving functions.
1. Comprehensive protection functions including phase sequence, short circuit, locked rotor, phase loss, overload, and imbalance.
2. Water shortage, high temperature, and overpressure protection.
3. Alarm protection against filter clogging and sensor failure. Fully meets the needs of continuous uninterrupted operation under unattended conditions. A uniquely developed multi-segment speed control program automatically adapts to changes in air consumption, without releasing excess compressed air. Provides maximum balance between air production and power consumption. RS485 communication protocol and remote control module allow for remote monitoring of compressor operating status and parameters, and remote control of compressor start and stop.
