KAESER Rotary Screw Compressors & Industrial Air Compressors

More and more customers throughout the world rely on the quality of KAESER compressed air systems, benefitting from optimum compressed air availability combined with low life-cycle costs.

Supplied as belt drive from 2.2 to 22 kW, direct drive (or gear driven) from 18.5 to 515 kW, and with oil-free dry screw model options from 30 to 355 kW, all KAESER screw compressors have an operating pressure range from 5.5 bar – 15 bar, rated at 100% full load duty.

(Lower pressures are available on request).

The KAESER SIGMA Profile

Developed by KAESER and continually enhanced ever since, the SIGMA PROFILE brings power savings of up to 15% 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.

A given drive power can be used to turn a smaller airend at high speed or a larger airend at low speed. Larger, lower-speed airends are more efficient and deliver more compressed air for the same drive power.

This is why KAESER builds airends with optimised rotor profiles that operate at the slowest drive speeds possible to achieve significant savings in energy costs.

Key Benefits

Low Life Cycle Costs

Energy costs taken over the lifetime of any compressor add up to many times that of the initial capital cost, which can make any difference in purchase price a false economy.

Maintenance Friendly

All maintenance work can be carried out from one side of the unit. The left-hand housing cover is easily removed, allowing excellent accessibility to all components.

Heat Recovery

Every rotary screw compressor converts a full 100% of the electrical drive energy supplied to it into heat energy. Up to 96% of this energy can be recovered and reused for heating purposes.

A compressed air audit comprehensively evaluates your compressed air system. Our skilled engineers will assess your system’s performance, identify inefficiencies, and recommend optimising energy consumption and reducing costs.

Kerr Compressors offers air compressors to suit various applications and industries. Our product range includes rotary screw, piston, and oil-free air compressors. We also provide specialised solutions for aquaculture, marine, and offshore environments.

Air management involves optimising the production, distribution, and consumption of compressed air within a facility. It includes various components and processes, such as air compressors, dryers, filters, and piping systems. By carefully managing these elements, businesses can improve energy efficiency, reduce operational costs, and enhance overall system performance.

To ensure the reliability of your compressed air system, regular maintenance and service are vital. Kerr Compressors offers comprehensive service and maintenance plans to keep your system running efficiently and minimising downtime.

Rotary screw air compressors use two intermeshing screws to compress air, offering continuous and efficient operation. Piston air compressors use a reciprocating piston to compress air, providing a more pulsating airflow. The choice between these two types depends on factors such as required airflow, pressure, and duty cycle. Our experts can help you determine the best solution for your specific needs.
