250HP 185KW PM VSD screw air compressor

250HP 185KW P VSD screw air compressor - High-efficiency industrial air compression solution This 250 HP permanent magnet variable frequency screw air compressor (model ZAY-250) is a cutting-edge industrial air compression system designed for high-performance applications. The compressor combines the latest permanent magnet motor technology with an advanced variable frequency drive system to provide excellent energy efficiency and operational reliability. With an overall size of 2800*1900*1950 mm and a weight of 4200 kg, it is designed to provide stable and precise compressed air output in harsh environments. The product integrates an IE5 energy-efficient permanent magnet synchronous motor, which ensures optimal power utilization while maintaining the working pressure within a stable range of ±0.1 bar.

 

The 250 HP Screw Air Compressor is a high-end industrial power equipment that integrates a permanent magnet synchronous motor (IE5 energy efficiency level) and intelligent variable frequency control. Its core features include: adopting a two-stage screw main engine design, optimizing the compression ratio distribution, and improving the exhaust efficiency by 12%-15% compared with the single-stage model; equipped with a vector variable frequency drive system (0-100Hz stepless speed regulation), real-time matching of gas demand, and comprehensive energy saving of up to 35%-55%; the working pressure is stable within ±0.1bar, suitable for high-precision scenes such as laser cutting and semiconductor manufacturing; the direct connection structure reduces transmission loss, the protection level reaches IP54, and the low noise design is <75dB (1 meter distance), meeting the stringent environmental requirements. However, it should be noted that the ambient humidity must be controlled below 90% to ensure the performance of the permanent magnet.

 

The core advantages of 250HP permanent magnet variable frequency Screw Type Compressor are high efficiency, energy saving, intelligent and stable: it adopts IE5 ultra-high energy efficiency permanent magnet synchronous motor (efficiency ≥ 96%) and two-stage compression technology, which saves 35%-55% energy compared with traditional industrial frequency models; it realizes 0-100% stepless speed regulation through vector variable frequency control, and the air pressure fluctuation is controlled within ±0.1bar, which is suitable for high precision requirements such as laser cutting and chemical processes; the direct drive structure reduces mechanical loss, IP54 protection level, low noise design with noise <75dB at 1 meter distance, and supports wide temperature operation from -15℃ to 45℃; the intelligent control system can monitor energy consumption in real time, automatically match the load, and improve energy efficiency by 18% when multiple machines are connected in parallel, but the cooling system needs to be maintained regularly to ensure the service life of the permanent magnet.

 

Single Phase Air Compressor is widely used in the heavy industry due to its high efficiency, energy saving and precise pressure supply. In the iron and steel metallurgical industry, it provides a stable high-pressure gas source (pressure range 7-10bar) for blast furnace coal injection and continuous casting equipment; in the chemical industry, it is used for stirring and gas transportation in large reactors (explosion-proof design applicable); in the energy industry, it serves shale gas fracturing operations; in shipbuilding and bridge construction, it drives heavy pneumatic tools (instantaneous load response time <0.5 seconds). Its variable frequency control system (PID accuracy ±0.5%) can intelligently dispatch multiple devices, and is particularly suitable for scenes with large fluctuations in gas consumption, such as automotive welding lines and glass float production lines. According to tests, the energy consumption is reduced by 42% compared to the industrial frequency model, but the cooling system needs to be regularly maintained to ensure that the permanent magnet motor can operate stably in an environment of -15℃~45℃.
