[INQ. NO. 1703M34] Since its founding, LHE has made tangible efforts, such as Business-University Joint Research to overcome restrictions in using the existing plate heat exchangers at high temperatures and pressures, and to develop more efficient heat exchangers based on the accumulated technologies.
As a result of these ceaseless and various efforts, it could secure 25,000ton and 50,000 ton hydraulic presses, creating a world-class production facility, with its own technology.
On the way from its origins as a small venture business, LHE won a hard-to-get order (Crystalizer Reactor and Heating & Cooling Device) without an appropriate production facility, but only with its pure technology and customers’ trust. It has been able to design and develop a world-class hydraulic press with its own technology through ceaseless efforts with much trial-and-error.
Manufacturing Heat Exchangers with Modernized and Optimized System
LHE’s production facilities are equipped with a modernized and optimized system for manufacturing heat exchangers. The quality of heat plate is directly related to the performance of the plate heat exchanger.
Therefore, it tries its best to live up to customers’ expectations by providing a various range of heat exchangers such as large, medium, small and mini-sized plates fabricated by 50,000, 25,000, 10,000 ton hydraulic presses.
The plate heat exchanger is fixed by numerous thin and corrugated heat transfer plates, hanging between the carrying bar on the above and the guide bar on the below. These heat transfer plates provide flow channels for two kinds of fluids, and the chevrons on the heat transfer plate make the turbulent flow and act to support the plate against the pressure difference between the two fluids. The plate pack is to be placed between the fixed cover and the movable cover, and fixed with tie bolts.
As for its characteristics, the plate heat exchanger is highly efficient in heat transfer compared with shell and tube heat exchanger, about five times more. It has a wide contact area so its durability and corrosion resistance are greatly improved by minimizing deformation and stress concentration. The gasket can be fixed tightly and quickly on the heat plate in the optimal condition with the dual fixing device (snap on type). It also features anti-vibration design with easiness to assemble and disassemble.

development through physical compaction. Resource cycling of cold patch is possible by using 100% recycled asphalt aggregate and nonvolatile special agent. Energy efficiency and reduction of CO2 emission is achievable in asphalt plants by producing room temperature.
EPO-AS, a high-temperature asphalt mixture using epoxy resin as binder, is an excellent asphalt concrete pavement that has very high strength, resistant to plastic deformation and high-performance for bridges and heavy traffic zones.
EP-COAT is an epoxy primer to increase the adhesion and water resistance of new and old asphalt, steel plate decking, and concrete slabs in the repairing of general asphalt and concrete pavement. This solution is made for pavement for new steel plate deck and concrete bridge, repairing pavement steel plate deck and concrete bridge, and pavement for heavy traffic roads and checkpoints.
RMC, an asphalt modifier material, mainly composed of thermoplastic elastomer, which enhances deformation resistance, low temperature crack resistance, and fatigue resistance, compared to the normal asphalt pavement, by adding in plant mix method in asphalt plant.
S-Phalt is a high-viscosity modified asphalt. It is added with RMC modifier during manufacturing asphalt mixture. It has high porosity that allows rainwater to drain through the continuously porous asphalt paving.
days. It ensures improved resistance to plastic deformation by using high viscosity modifier; prevents secession of aggregate owing to the increased adhesion; and ensures higher visibility of the road when it rains and driving at night. This solution also helps the significant mitigation of noise (3~5Db) when compared to the dense asphalt pavement.
S II Asphalt, a modified asphalt concrete added with RMC modifier by the plant-mix method when producing asphalt mixture, enhancing deformation resistance, low temperature crack resistance, and fatigue resistance in repeat loading, compared to the normal asphalt pavement. This solution is intended to be used for construction of highways and motorways, and general roads frequented by heavy traffic, bridges and overpasses, tunnels and underpasses, and roads with serious rutting and deformation.
Color Road-Con is a new concept of pavement method designed for sidewalks, driveways, and riverside roads, which is added with high viscosity RMC modifier and a variety of color pigment in consideration of scenic urban landscape (both water drainable type / non drainable type available).
A condenser is required to cool down the hot refrigerant coming from a compressor, so it is located at the front of a car where it can be exposed to the maximum amount of air. As the hot refrigerant flows into the condenser, it dissipates heat by flowing through a system
of ultra-thin tubes that are held together by fins.
compressed into high pressure gas and sent to the condenser. These units compress liquid refrigerant into gas while keeping the refrigerant flowing through the airconditioning system. Compressors are also filled with special lubricating oil, and some of this oil circulates with the refrigerant through the air-conditioning system, keeping all of the parts lubricated.
A radiator is located at the front of a car’s engine, just behind the condenser, and is the most important component of the cooling module because it keeps the engine from overheating. The radiator is made up of a radiator core, along with two plastic side tanks, and all the necessary connections and attachments. The radiator core is made up of a network of fins and tubes that run either horizontally or vertically, depending on the application.
vehicles from Hyundai, Kia, SsangYong and GM Korea, but also foreign-made cars from Toyota, Honda and BMW. The maker can supply automotive parts under the basis of both OEM and genuine parts. Its products can also carry the firm’s own brand “DJ parts.”
Korean-made cars, including CRDi (Common Rail Direct Injection) dieselengine cars. They have the same quality as those being supplied to Mercedes Benz, BMW and Audi.
Hyundai’s gasoline-engine cars and European diesel-engine cars. They are similar to those being supplied to Hyundai, Kia and Ssang Yong.
Recently, the firm has acquired the Korean agency for Bosch.
oriented attitude, we put all our efforts into finding ways to achieve mutual prosperity with our foreign customers, and are always ready to satisfy any complex requirements from overseas buyers, “ said the company’s spokesperson Raul Kim.
accumulated during 20 years of experience and research in the manufacture of freezing equipment and panels.
and operational noise. With it, users do not need to operate a refrigerator attached to the car engine.
certifications like ISO 9001 and has actively explored overseas markets in more than 30 countries, especially in Southeast Asia, Southwest Asia, the Middle East, Latin America and Africa. It has also been designated as a “Promising Export Company” by Korea’s Small & Medium Business Administration. Moreover, it has registered itself for the UN procurement market.
Other hot-selling models include the IZ-33 electric power ULV sprayer. With the main body made of aluminum and stainless steel, the model weighs only 5Kg. Ideal for pest control, it offers maximum chemical discharge rate of 60l per hour with its dimensions running 460 (L) x 290 (H) x 260mm (W). Easy to handle, it delivers ten-times higher productivity than air-pressure-type models.
since the products such as COM type, RLO type, RVC type, LIN/BSS type are emerging.
Alternator rectifiers also apply for 12V and 24V charging systems with press-fit type zener diode. Alternator die-cast and extrusion-type heat sink are available with welded connection to the stator wire.
