What Solge does

Solge (주)솔지) is a South Korea-based industrial lubrication management specialist founded in 1999 and headquartered in Daegu. The company's core business is providing integrated products and services that detect, remove, and prevent lubricant-related failures in industrial equipment such as manufacturing plants, power generation facilities, marine vessels, wind turbines, hydraulic systems, gearboxes, and compressors. Its technical offerings are organized into three proprietary product lines: DETECT (online sensors including the SOCM10000/11000 solid contamination and moisture sensors and the WatchCon-Metal electromagnetic wear-particle sensor, plus Computrac moisture measuring instruments), REMOVE (oil purification units, filters, and OFU Series portable filtration equipment), and PROTECT (air breathers and contamination prevention equipment). Solge also distributes Royal Purple industrial hydraulic oils and consumer automotive engine oils under authorized distributor rights and sells a Solvancer varnish-removal additive.

The company monetizes through a mix of one-time hardware sales (sensors and equipment with perpetual licensing), pay-as-you-go oil analysis services through its KOLAS-accredited Wearcheck laboratory (with NORMAL turnaround of approximately one week, SEMI-EXPRESS next day, and EXPRESS same-day tiers at 50% and 100% surcharges respectively, plus a 1,000 KRW per-bottle sample disposal fee), equipment rentals, on-site resident lubrication management contracts, and structured training programs ranging from 3 to 20 hours including NORIA lubrication education and ICML international certification exam preparation. Distribution combines direct enterprise sales with authorized regional distributors across Korea; the company also operates a multilingual website (KOR/ENG/CHN/JAP), a YouTube demonstration channel, and a metaverse exhibition hall.

Solge is privately held and founder-controlled, with CEO Kim Tae-heon (김태헌) and Vice President Kim Hyun-deok (김현덕), supported by a small management team of general managers and senior staff in the oil analysis lab. With 11–50 employees and no disclosed external funding, M&A, or parent-company affiliations, the company competes through its KOLAS-accredited testing capability, international training/certification partnerships, and proprietary sensor portfolio rather than through scale or capital intensity.
