Reciprocating Compressor

The reciprocating compressor is one of the most widely used compressors in petrochemical complexes, refineries, and processes related to natural gases. Therefore, Havayar has always tried to support its customers by producing and supplying reciprocating compressors which have the highest quality that require minimum maintenance in the long term.

A reciprocating compressor is easily used in a variety of applications, while any other type of compressor may be more suitable for a particular application. For example, centrifugal compressors are commonly used when power consumption is above 2 MW, gas molecular weight above 10 and gas outlet pressure less than 100 MPa. Also screw compressors are preferred in the power range between 10 and 500 kW and outlet pressure less than 30 bar. Piston compressors have good efficiency because the piston rings perform good sealing and also very low heat transfer makes the efficiency of this type of compressor very close to isentropic. In low-speed compressors, the efficiency of 85-95% is easily achievable, and in high-speed compressors, this value ranges from 80 to 90%. Mechanical efficiency, which is caused by friction and structural losses, is usually 95 to 98%. From the point of view of efficiency, other types of positive displacement compressors actually have lower efficiency and more leakage. One of the advantages of all positive displacement compressors is their operation with different types of gases and even variable density, and the reciprocating compressor is also in this group. Compared to centrifugal compressors, these compressors have higher maintenance costs and take up more space. But instead, they are much more efficient and produce higher range of output pressure. Centrifugal compressors use more power to pressurize low molecular weight gases, which is why hydrogen compressors are usually reciprocating type.

Types of air piston compressors

Air Reciprocating compressor is designed according to API 618 standard, the latest version. They also comply with many international construction guidelines and codes and customer requirements.
