Kaeser Kompressoren

What Kaeser Kompressoren does

Kaeser Kompressoren SE is a privately held, family-owned German manufacturer of compressed air systems founded in 1918 and headquartered in Coburg, Germany, with approximately 8,000 employees and operations in roughly 140 countries. The company designs and builds rotary screw compressors (SX, SM, SK, ASK, ASD, BSD series up to 515 kW), reciprocating compressors and boosters, rotary screw and turbo blowers, portable MOBILAIR compressors, and a full air-treatment ecosystem including SECOTEC, KRYOSEC, CALOSEC, HYBRITEC, and KMM dryers alongside KAESER filters, ACT activated carbon adsorbers, and condensate handling equipment. Its technical differentiation rests on the proprietary SIGMA PROFILE rotor design, which the company states consumes 10-20% less energy than conventional rotors of equivalent air delivery, complemented by SECOPACK LS latent-heat storage and a digital control layer (SIGMA CONTROL 2, ECO CONTROL 3, SIGMA AIR MANAGER 4.0) that integrates compressors, dryers, and sensors via industrial protocols including Modbus TCP, Profibus, Profinet, and DeviceNet.

Kaeser earns revenue through five distinct streams: direct hardware sales of compressors, blowers, and air-treatment systems; KAESER AIR SERVICE aftermarket maintenance, inspection, full-service contracts, and consumables; equipment rental for portable compressors; the SIGMA AIR UTILITY operator model in which Kaeser owns and operates the compressed air installation on the customer's site; and financing/lease arrangements. Go-to-market combines wholly-owned subsidiaries for enterprise accounts with a qualified partner network serving mid-market and SMB buyers across all served verticals. The customer base spans manufacturing, food and beverage, pharmaceutical and medical technology, water management, construction, oil and gas, mining, electronics, trades and workshops, aquaculture, marine, and agriculture, with application-specific engineering and energy-efficiency analysis (KESS, ADA) positioned as the primary demand-generation mechanic. The company is led by Thomas Kaeser (Chairman of the Executive Board), with Tina-Maria Vlantoussi-Kaeser on the Executive Board and Carl J. Kaeser chairing the Supervisory Board.
