Profile: Howden Compressors Ltd. is a designer and manufacturer of rotary screw compressors that are used for a variety of demanding gas compression and refrigeration applications. We produce bare-shaft screw compressor units. We also manufacture both oil injected and oil free screw compressor units. Our refrigeration packages cover applications like dew point control, process gas chilling, storage boil off gas recondensing and mine air coolers. Our Turbo compressors are used in applications like sulphur recovery, sulphuric acid plant, flue gas desulphurization and process gas blowing applications. This compressor enhance variable flow by means of variable vane diffusers, pre-rotational inlet guide vanes or a combination of both systems. It supports with inherent anti-surge protection. It is designed to maximize operating efficiency and provide variable capacities over a wide duty range. Fully automatic capacity control within this compressor is achieved from a single input signal, processed and relayed to the electric, pneumatic or hydraulic, guide vane actuators.
