3 HOWDEN TURBO BLOWERS & COMPRESSORS 1 TURBO BLOWERS & COMPRESSORS FROM THE GLOBAL LEADER IN AIR AND GAS HANDLING HOWDEN IS ONE OF THE WORLD S LEADING ENGINEERING COMPANIES IN THE FIELD OF AIR AND GAS HANDLING. FOUNDED IN 1857 IN GLASGOW BY JAMES HOWDEN AND INITIALLY SPECIALISING IN MARINE STEAM ENGINES AND BOILERS, THE COMPANY BUILT A REPUTATION FOR INNOVATION AND QUALITY THAT LED TO ITS STEADY GROWTH INTO A GLOBAL ORGANISATION WITH A WORKFORCE OF OVER 4,000 PEOPLE IN 17 COUNTRIES. HOWDEN PROCESS COMPRESSORS Part of Howden s compressor division, Howden Process Compressors (HPC) designs, manufactures, supplies and supports the Howden SG range of high efficiency turbo blowers & compressors. The SG range encompasses industrial type blowers used in the power, mining and water industries, whilst our turbo compressor version is best suited for API specification type applications in the downstream oil & gas industry. API Turbo Compressors Industrial Turbo Blowers Howden s range of compressors and complete compressor packaged systems are used in the petroleum, petrochemical, refrigeration, fuel gas and other markets where performance and reliability are crucial. We have over one hundred years of experience behind us and supply our compressors to API or equivalent industry standards. We designed and supplied the first diaphragm compressor and were the first company to commercialise screw compressor technology. We have built on this experience and now offer screw, piston (reciprocating) and diaphragm process gas compressors, and highly efficient turbo blowers & compressors capable of meeting the most demanding conditions.
4 2 HOWDEN TURBO BLOWERS & COMPRESSORS THE HOWDEN SG RANGE OF HIGH EFFICIENCY TURBO BLOWERS & COMPRESSORS All Howden s turbo blower & compressor models are designed and supplied as single stage, integrally geared units and complete packages, and provide high efficiency over a wide operating range. Systems are designed and built to API and other industry standards for applications in the petrochemical/refining, power, mining, industrial and water industries. HISTORY OF HOWDEN TURBO BLOWERS & COMPRESSORS Acquired by Howden in 1997 to complement their range of compressor technologies and solutions, Bryan Donkin, based in Chesterfield, UK, was one of the longest established designers of rotary blowers and compressors with a history extending back to For almost 100 years, as Bryan Donkin and now Howden, we have supplied turbo blowers & compressors for a wide range of applications in international markets. Today, Howden turbo blower & compressor systems are designed, manufactured and tested on-site at our centre of excellence facility in Renfrew, UK, and global aftermarket support activities are managed from our regional service centre in Chesterfield, UK. KEY PRODUCT FEATURES ADAPTABILITY Industrial or bespoke API Standards 617, 672 & 614 Compact skid design or separate lube oil console Turn down to 45% volume flow EFFICIENCY High efficiency designed impeller Maintains optimum efficiency in all duty points RELIABILITY Ease of maintenance Minimum downtime Designed to suit all environments
