Rotary Screw Compressors SX - HSD Series With the world-renowned SIGMA PROFILE Flow rate 0.25 to 85.2 m³/min, Pressure 5.5 to 15 bar

KAESER KOMPRESSOREN – The global compressed air systems provider The company was established by Carl Kaeser Sr in 1919 as a machine workshop, but started on the road to becoming one of the world’s leading providers of compressed air systems in the 1950s, when Carl made the decision to start manufacturing reciprocating compressors. The breakthrough on the road to today's market-leading position among the world's top compressed air system suppliers came when KAESER developed the rotary screw airend featuring the SIGMA PROFILE. Main plant, Coburg The KAESER headquarters in Coburg currently...

More compressed air for less energy KAESER SIGMA PROFILE Developed by KAESER and continuously enhanced ever since, the KAESER SIGMA PROFILE achieves power savings of up to 15 percent compared with conventional screw airend rotor profiles. All KAESER rotary screw airends feature this energy-saving rotor profile and are designed to ensure maximum energy efficiency. The generously-sized, precision-aligned roller bearings and close-tolerance machining guarantee long service life and outstanding reliability. Energy-saving compressor airend with SIGMA PROFILE rotors A specific drive power can be...

Energy-saving SIGMA CONTROL 2 compressor controller The SIGMA CONTROL 2 control unit coordinates compressed air generation and consumption. With its intelligent control, this advanced system prevents inefficient energy usage, especially during partial load operation. KAESER offers various different control modes to suit every possible requirement. The SIGMA CONTROL 2 fulfils the highest possible requirements for an internal compressor controller and is based on advanced industrial computing technology. The control unit is linked to interchangeable input and output modules, allowing flexible...

KAESER rotary screw compressors with belt drive up to 22 kW KAESER rotary screw compressors with belt drive provide outstanding efficiency and reliability. KAESER was one of the first compressor manufacturers to introduce the belt drive system. The automatic tensioning device*) ensures continually high transmission efficiency of the belt drive in KAESER rotary screw compressors over their entire service life. This, of course, also reduces maintenance costs. The automatic tensioning device assures consistent transmission efficiency and drive performance throughout the machine’s entire...

Heat recovery All maintenance work can be carried out from one side of the unit. The left-hand housing cover is easily removed to allow excellent component accessibility. Every rotary screw compressor converts 100 % of its input electrical drive energy into heat energy. Up to 96 % of this energy can be recovered and reused for heating purposes. This not only reduces primary energy consumption, but also improves the company’s total energy balance.

The left-hand housing cover is easily removed to allow excellent accessibility to all service points. Inspection glasses allow convenient inspection of fluid levels, condensate drain and drive belt tension whilst the unit...

KAESER rotary screw compressors All-in-one systems up to 22 kW With KAESER's intelligent system design, the compressor and refrigeration dryer are both completely separate, independently functioning modules. This protects the dryer from exposure to heat from the compressor package, thereby enhancing reliability. The dryer shut-down feature (not available on SXC models), which can be selected via the compressor controller, is linked to compressor operation and significantly reduces energy consumption. All components are generously-sized, yet easily accessible for maintenance and servicing...

KAESER rotary screw compressors with 1:1 drive up to 500 kW In compressed air packages featuring 1:1 direct drive, the motor drives the airend directly without transmission loss via a maintenance-free coupling. 1:1 direct drive rotary screw compressors provide outstanding performance and enable significant savings. KAESER's comprehensive range of specially designed airends are manufactured and developed to meet every compressed air user’s needs. No energy is lost during power transmission. The large, low-speed airends save additional energy, whilst the 1:1 drive reduces maintenance costs....

Required temperature assured Heat recovery According to operating conditions, the innovative Electronic Thermo Management (ETM) system dynamically controls fluid temperature to ensure safe prevention of condensate accumulation and also boosts energy efficiency. Every rotary screw compressor converts 100 % of its input electrical drive energy into heat energy. Up to 96 % of this energy can be recovered and reused for heating purposes. This not only reduces primary energy consumption, but also improves the company’s total energy balance.

Future-proof refrigerant Stay cool with The new EU 517/2014 F-Gas Regulation is intended to minimise emissions of fluorinated greenhouse gases and therefore contribute to limiting global warming. KAESER’s new T-systems are equipped with R-513A refrigerant, which has a very low GWP (Global Warming Potential) value. This means that these efficient dryers will be future-proof for their entire life cycle.
