Hyosung to Supply Cooling Pumps for SKT’s Ulsan AI Data Center

What happened

According to industry sources on Nov. 4, Hyosung Goodsprings, a pump manufacturing subsidiary of Hyosung Group, has secured contracts to supply sensorless inline pumps for both the 40MW first-phase facility (Building A) and the 60MW second-phase facility (Building B) at SK Telecom's (SKT) Ulsan AI data center, with orders covering the data center's 100-megawatt (MW) capacity; the total supply value for the 100MW Ulsan data center is estimated at around 4 billion won, based on a set of pumps for a 40MW facility costing approximately 1.5 billion won (a 40MW data center typically requires about 20 to 30 pumps, so the 100MW data center would need more than 50 pumps). The sensorless inline pump (ILP 150-400) was unveiled at Data Center Korea 2026 in Yangjae-dong, Seoul, held Nov. 4–6; it automatically adjusts motor speeds according to server cooling loads, controls operating conditions without separate flow sensors, and has added a total harmonic distortion (THD) monitoring function, with its integrated inverters supplied by ABB, a Swedish-Swiss power technology company. With SKT planning to expand its domestic AI data center capacity to 15 gigawatts (GW) by 2035 — including establishing AI data center clusters exceeding 2GW in the Yeongnam region and 1GW in the southwestern region, before gradually expanding domestic capacity to 5GW starting in 2029 — Hyosung Goodsprings' cooling pump shipments are expected to increase further, and total pump demand could reach approximately 600 billion won applying the same cooling equipment requirements. Hyosung Goodsprings also supplies cooling pumps to other domestic data center operators, including the 35MW Deogi-dong IDC in Ilsan, the 80MW GPC IDC in Hwaseong, the 50MW TIMBUKTU IDC in Ansan and the 25MW Global Cloud Center (GCC) IDC in Ansan. The company's revenue declined slightly last year to 230.1 billion won from 236.3 billion won a year earlier, while operating profit increased approximately 48% to 20.9 billion won from 14.2 billion won over the same period.
