Haein Accelerates Expansion of Emergency Generator Supply...From Semiconductor Factories and Hospitals to AI Data Centers

Long-Lead Items Requiring Orders Over Two Years in Advance
Direct Coordination with CAT on Supply and Delivery Schedules,
Integrated Support from Installation to Maintenance

Haein is expanding its supply of emergency generators, focusing on artificial intelligence (AI) data centers.

According to Haein on September 30, the company has supplied Caterpillar power generation equipment to sites highly sensitive to power outages, such as semiconductor factories, hospitals, broadcasting facilities, and high-end residential complexes. Based on this experience, Haein plans to expand its supply channels to data centers, which require large-scale power capacity.

The sites that Haein has supplied with power generation equipment so far are places where production or services come to a halt, or where critical facilities such as fire safety and water supply are interrupted immediately due to a blackout, leading directly to losses and safety concerns. Therefore, in addition to the initial purchase price, operational reliability during emergencies and long-term maintenance conditions have become key selection criteria. For AI data centers, these requirements become even stricter. Since servers run 24 hours a day, even a brief power outage can result in service disruption.

Data centers consume a large amount of electricity, and their power loads can change rapidly depending on computational demands. The Caterpillar C175-20 supplied by Haein is a large 3,900kW generator, equipped with '100% block load acceptance' capability, which allows it to instantly take on significant loads. This specification is well-suited for data center environments, which need to handle large-scale loads immediately after a blackout.

Emergency generators must maintain required performance even when the engine, generator, control devices, cooling and exhaust systems, and fuel supply systems all operate in tandem. The larger and more complex the setup, as with data centers, the more important it is to verify the entirety of the system rather than individual components. Caterpillar designs and manufactures generator sets and conducts performance testing on complete packaged products, providing highly reliable verification data for the assembled components.

As global demand for generators rises, particularly for AI data centers, large generators have become long lead-time items, requiring advance orders at least two years ahead. Delays in placing orders can impact data center construction and operational schedules. Haein selects specifications according to the customer’s power design and construction timeline. Additionally, the company shares projected demand and project progress directly with Caterpillar, discussing production volumes and delivery times. In a supply-constrained market, the ability to secure units on time becomes a key competitive advantage.

Even after installation, power generation equipment requires regular inspections and parts replacements over extended periods to ensure proper emergency operation. Haein supports after-sales management through its team of dedicated local engineers, the Cheonan parts warehouse, and Caterpillar's Asia-Pacific supply chain. As data center supply increases, so does the demand for post-installation maintenance.

A Haein representative stated, "We are expanding our supply and maintenance expertise, built up at sites where power interruptions are unacceptable, such as semiconductor factories, hospitals, and broadcasting stations, into AI data centers. By combining Caterpillar's product performance and thorough verification processes with Haein’s supply and maintenance capabilities, we will provide emergency power solutions that our customers can rely on for the long term."
