Heavy–Duty Centrifugal Compressors
Equipment /Compressors

A wide range of centrifugal compressors according to API 617 are supplied. These compressors with high degree of reliability and low maintenance cost are used in petrochemical and refinery industries, natural gas, steel and cement plants, food industries as well as transportation.
Our centrifugal compressors could be supplied with electro motors as well as turbines, equipped with complex control systems in order to meet projects requirements in various pressures, capacities and powers.




HAVAYAR Company combines the advantages of custom-built machines (maximum efficiency, layout flexibility, materials selection etc.) and standardization (proven reliable components; availability of spare parts).
These compressor series comes in a range of sizes. For each size the baseplate, gearbox, stage volutes, cooler shells, oil and gas piping, and auxiliaries are standardized.

Machines can be produced to meet the individual requirements of each application through the appropriate selection of key design factors including:
  1. Number Of Stages
  2. Shaft Rotational Speed
  3. Diameter Of Impellers
  4. Exchange Surface Of Coolers


Horizontally-Split Compressors




Centrifugal Compressors With Horizontally Split Casing Intended Particularly For Flammable, Toxic Or Explosive Gases Used In All Branches Of Industry And In All Cases Where Outer Hermetic Seals Must Be Used. 

Outlet Seals Can Be Designed As Oil Seals (Contact Type Or Floating Ring Seals) Or Dry Gas Seals. These Machines Are Predominantly Used In The Chemical Industry As Process As Process Or Refrigerating Compressors. 

If Necessary, They Can Be Provided With Up To Two Intercoolers And Refrigeration Compressors With Up To Two Side Streams. 
In Order To Increase Control Ranges, The Compressors Can Be Equipped With Inlet Guide Vanes On The First Stage.

Vertically-Split  Compressors




Vertically Split (Barrel) Centrifugal Compressors Are Used To Compress Gases In Various Chemical Technologies, Such As Crude Oil Processing, Urea Production Or Natural Gas Storage & Treatment. 
A Common Feature Of These Compressors Is That Their Assembled Flow Oath Is Placed In A Cylindrical Vessel Closed By Means Of Heads. 

In Order To Prevent Escape Of The Gas Handled, These Compressors Are Provided With Outer Hermetic Seals That Can Be Designed As Contact Type Oil Seals, Floating Ring Oil Seals Or Dry Gas Seals. 
Standard Pressure Range Of Vertically Spilt Centrifugal Compressors Reaches Up To 200 Bar, Machines For Pressures Can Be Design Individual Basis.

Integrally Geared Compressors




Integrally Geared Compressors Are Design Based On API 617 (672). The Compact Design Of These Compressors With Use Motor And Turbine Drivers Makes The Special Gas Processes Possible In Petrochemical, Refinery, Chemical, Cement, Steel And Transportation Industries. 
The Maximum Achievable Pressure For These Compressors Could Be More Than 170 Bar And The Maximum Suction Capacity Could Be 120,000 M 3 /Hr.

The Multi-Shaft Configuration Allows Frequent Intercooling, And Therefore Better Compression Efficiency Compared To Traditional In-Line Centrifugal Compressors. Axial Intel Flow Guarantees And Optimum Aerodynamic Design, And Therefore Very High Stage Efficiency. 
Due To Its Rugged Mechanical Design, This Type Of Machine Guarantees Very High Reliability.
