Engineering the Future of Heat Exchangers

About us

At LHE, we engineer the future of heat exchangers for a more efficient and sustainable tomorrow.

We design and manufacture heat exchangers that move industries forward — with performance, precision, and reliability at the core.

Founded in 2001 as DHT and now known as LHE (Leader Heat Exchanger), we’ve grown into a global supplier of advanced plate heat exchangers for Marine, Energy, HVAC, and beyond. Our mission is clear: design high-efficiency solutions that meet real operating conditions and deliver them with the consistency customers count on.

Our production facilities in Korea are built for scale and precision. With high-tonnage forming presses, automated QA, and cleanroom plate production, we manufacture every unit to meet tight thermal specs and global compliance standards.

At the center of it all is our R&D team. From new materials and performance testing to optimized plate design, we constantly push what heat exchangers can do to help customers stay ahead in fast-changing markets.

And with service centers in 13+ countries, we support every unit long after delivery. Maintenance, troubleshooting, spare parts — our global network is built to keep your systems running efficiently, year after year.

Global reach. Local support.

LHE supports customers in over 13 countries through a network of 16+ specialized agencies and service centers — providing fast diagnostics, certified maintenance, and access to OEM-quality parts wherever you operate.

From marine docks to industrial plants, our teams deliver expert support across the full lifecycle of your heat exchangers. Backed by centralized QA and engineering in Korea, every site is equipped to meet the same standards in testing, reconditioning, and thermal performance optimization.
