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.
