Industrial Gas Compressor Manufacturer - FKW

The piston compressor is a type of positive displacement compressor. Due to its characteristics such as wide ranges of discharge pressure and displacement, and high volumetric efficiency, it is widely used in many industries including petrochemical, silicon and fluorine chemical, hydrogen production, and metallurgy. For piston compressor models, the piston force ranges from 25 to 800KN, the maximum pressure can reach 25 MPa, and the rotational speed ranges from 300 to 1000rpm. There are various models such as M, D, L, and P types, more than 60 product series. The number of compressor stages can achieve pressure matching from one stage to six stages. The products comply with the API 618 standard and fully cover market demands.

The diaphragm compressor is a positive displacement compressor with a special structure. As its cylinder requires no lubrication, has excellent sealing performance, and the compressed medium does not come into contact with any lubricant, diaphragm compressors can compress gases with extremely high purity, generally reaching 99.999%. Due to their "zero pollution" and "zero leakage" characteristics, diaphragm compressors play a crucial role in the development of hydrogen energy. The maximum displacement can reach 4000 Nm³/h, and the compressor piston force can reach 250 kN. In particular, the introduction of 90 MPa high-pressure, 250 MPa, and 320 MPa ultra-high-pressure diaphragm compressors has solved the problem of domestic substitution and "necklace" technologies in key national fields, overcome important challenges that have plagued key national sectors for 30 years, and significantly enhanced the security capabilities of key national fields.

The high-speed compressor is a positive displacement piston compressor. It is widely used in industries such as petrochemical, silicon & fluorine chemical, hydrogen production, and metallurgy due to its characteristics of wide discharge pressure and displacement ranges, high volumetric efficiency, and small footprint. Our company provides professional customization according to customers' actual working conditions to deliver compressor products fully meeting on-site requirements. The product types include M-type and D-type, capable of achieving 1 to 4 stages of compression, featuring high rotational speed, high balance, and compact footprint.

The products cover the entire industrial chain scenarios such as hydrogen production, hydrogen filling and hydrogen refueling stations, integrated hydrogen production and refueling, residual hydrogen recovery, and hydrogen energy chemistry, and can provide a full set of solutions for gas compression equipment. The diaphragm hydrogen compressor has a maximum displacement of 4000 Nm³/h and a piston force of 250 KN. It features zero pollution and zero leakage of the compressed medium, and is fully automatic (one-key start and stop).

With China's diaphragm compressor technology continuously advancing in high-pressure, ultra-high-pressure, and high-displacement capabilities, the demand for application scenarios is rapidly expanding. Our company specializes in providing high-pressure and ultra-high-pressure diaphragm compressors (up to 320 MPa) for hydrogen energy, nuclear power, military, aerospace, and other critical sectors. Committed to technological innovation, we have developed proprietary high/ultra-high-pressure diaphragm compressors with independent intellectual property rights.
