GL-TURBO

What GL-TURBO does

GL-TURBO, LLC is a privately held, US-headquartered designer and manufacturer of industrial centrifugal turbo blowers serving municipal and industrial process-gas applications worldwide. The portfolio is anchored by two core product platforms: the GL Series integrally geared single-stage turbo blower (75 to 4,500 kW, flow to 120,000 m³/h, pressure to 3 bar) and the LS Series multistage centrifugal turbo blower (25 to 2,200 kW, 500 to 7,500 m³/hr, up to 1.7 bar delta pressure). These are complemented by CS control systems (blower control panels, process/sequencing controls, motor starters and VFDs), PS packaged systems (pre-engineered and custom turnkey skids), and a Customer Service line including the proprietary Remote Control System (RCS) for real-time monitoring across any brand of blower. Underlying technology centers on a combination vane control system (variable inlet guide vanes plus variable discharge diffuser vanes) that holds 95% design efficiency through most of the operating range, a backward-swept impeller for surge-safe operation, sleeve-type bearings for long maintenance intervals, optional forced-lubricated sleeve bearings for API 617 petrochemical service, and an LS architecture configurable from 1 to 10 stages with mixed impellers. Product development uses solid modeling, finite element analysis, CFD performance verification, and in-house compliant test stands supporting ASME PTC 9, ASME PTC 10, ISO 5389, ISO 1217, and API 617/672.

Revenue is generated through capital equipment sales (GL and LS hardware), custom and standard packaged systems, control systems and motor starters/drives, and professional services including installation, training, and RCS monitoring subscriptions. Pricing is not publicly disclosed; quotes are provided on request, and the company emphasizes a 20-year lifecycle value proposition and turnkey "One Source" responsibility. Distribution combines direct field sales from six owned offices (Marlborough, Houston, Wuxi, Farum/Copenhagen, Leipzig, Bangalore) with an authorized Global Reps network spanning 60+ countries, industry trade show participation (notably WEFTEC), and free energy analysis/site survey offers as top-of-funnel engagement. Primary customer segments are water and wastewater treatment, utility power (flue-gas desulfurization, fly ash, coal gasification), and petrochemical (sulfur recovery, refinery tail gas, H2S handling); secondary segments are mining, environmental (landfill/biogas), industrial, and vacuum systems/pneumatic conveying. Named reference customer includes HOFOR's Amagerværket Power Station in Copenhagen (FGD oxidation blower).

The company traces to a predecessor founded in Boston in 1998 with an initial focus on valves and blowers for wastewater treatment; the GL Series design was formally started in 2006 and the GL-TURBO name was adopted in May 2008 when the blower business was spun off as a standalone company. Key milestones since include the Wuxi plant opening (December 2013, 10,815 m², 300 units/year capacity), establishment of the Danish subsidiary GL-TURBO International, ApS (October 2015), the Lone Star Blower partnership for the Americas (November 2015), the GL-TURBO China IPO on the NEEQ third board (January 2016), the LS Series launch (April 2016), the GL-TURBO Houston manufacturing facility (September 2016), the Rewin financing partnership (July 2016), reaching 300 units sold (January 2017), and the HOFOR Amagerværket European reference win (December 2017). The US parent GL-TURBO, LLC remains privately held, with the China entity publicly listed. The company reports 5,000+ installed systems globally and principals with 200+ years of combined compressor-design experience from MIT and the former Northern Research & Engineering Corporation (NREC).
