SCR75 APM Base Mount 55KW VSD Screw Air Compressor
The SCR APM series represents an advanced range of energy-saving compressed air solutions. These compressors utilize Permanent Magnet Variable Speed Drive (VSD) technology to precisely match air output with real-time demand. By ramping motor speed up or down, the APM series maintains constant pressure while avoiding the energy waste associated with fixed-speed compressors that run unloaded. This intelligent control, combined with dual VSD technology (controlling both the main motor and cooling fan), results in significant energy savings of up to 50%, reduced CO2 emissions, and a reliable, soft-start system that minimizes electrical stress during startup.
Key Features
- Dual VSD Energy-Saving Technology: Inovance VSD independently controls both the main permanent magnet motor and the cooling fan motor, optimizing energy use and maintaining ideal operating temperatures.
- Super Premium Efficiency Motor (IE4 Equivalent): Features an oil-cooled, bearing-free permanent magnet motor with IP65 protection. The design includes high-temperature resistant UH magnets (up to 180°C) to prevent demagnetization and requires zero maintenance on the motor.
- Pure Soft-Start System: Standard soft-start technology ensures the starting current never exceeds the rated value, unlike traditional starters that can draw significant inrush current.
- Intelligent Controller: A 7-inch full-colour LCD touchscreen provides real-time operation data, maintenance schedules, fault logging, and graphical flow diagrams. It includes 4 energy-saving modes, remote monitoring capability, and multiple interface connections (RS485, Ethernet, USB, SD card).
- Innovative Air End: Features a new, improved rotor profile developed in Japan, designed for many years of reliable and efficient operation.
- Robust Cooling System: A 30% oversized cooler with anti-corrosion coating and a VSD-controlled cooling fan ensures optimal performance even in high-temperature environments.
- High-Efficiency Separation: The built-in separation system, designed and certified to AS1210, includes an oversized air/oil tank and a high-efficiency separator to ensure oil carryover is less than 3ppm.
- Durable Construction: An all-steel internal pipe system prevents leakage and premature ageing commonly associated with flexible pipes.
