Since its founding, LHE has made tangible eff orts, 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 effi cient heat exchangers based on the accumulated technologies.
As a result of these ceaseless and various eff orts, 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 eff orts 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 fi xed 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 fl ow channels for two kinds of fl uids, and the chevrons on the heat transfer plate make the turbulent fl ow and act to support the plate against the pressure diff erence between the two fl uids. The plate pack is to be placed between the fi xed cover and the movable cover, and fi xed with tie bolts.
As for its characteristics, the plate heat exchanger is highly effi cient in heat transfer compared with shell and tube heat exchanger, about fi ve 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 fi xed tightly and quickly on the heat plate in the optimal condition with the dual fi xing device (snap on type). It also features anti-vibration design with easiness to assemble and disassemble.

Alternator regulators apply for 12V and 24V charging systems with a wide range of operating temperatures, from -45 to +135. A self-compensating thermal circuit with custom sett ing voltage as well as custom package design is available. They are multifunctional with HIC & ASVR types, including LRC function, faulty warning and protection.
However, its parent company, HLB was established in 1975. And it has recently expanded its business into Bio-industry.
Penguin shares the pleasure with everyone regardless of age, health condition and swimming skills. The company helps anyone to give it a try and gather unforgett able memories. Penguin is the achievement of HLB’s technology and experience of manufacturing lifeboats over 40 years.
It produces refrigerated compressed air dryers, desiccant air dryers, membrane dryers, after coolers, chillers, oil-water separators, particulate & air fi lters, automatic condensate drains, PSA nitrogen generator, PAS oxygen generator, PSA hydrogen purifi er, PSA argon recovery and purifi cation plant, PSA CO, CO2 recovery and purifi cation plant, PSA methane recovery and purifi cation plant, PSA other gases separation and purifi cation plant.
Feroof tiles can be installed on existing asphalt shingles, which saves cost of uninstalling and prevents environmental waste. Feroof stone chip coated steel tiles are very easy to install, therefore, shorten installation time and save the labor cost. The installation requires no special training with weight of each tile about 2.6-7 a piece. They are also very fl exible so, when bent during installation, the basecoat will stretch instead of cracking.
ALH-380 is a handle that locks and releases automatically for sliding windows when closing and opening. It is easy to install so that it can be easily used for closing and opening windows. The security function has been upgraded with lock function eff ectively improved, bett er than the existing lock device, crescent.
ALH-115 is an another handle that locks and releases automatically.
ASP-021A is a roller for windows, which facilitates their movement when opening or closing. It endures high-load with very low noise so it is useful for long-term use. The durability test has been completed with 100,000 repetitions of opening and closing tests.
This company sells largely three categories of products – namely, mechanical parts such as grinding wheels and sisal wheels; bearings for power plants like pump sleeve bearings and rudder bearings for vessels. However, its most representative product is “LUNA 15GR Bearings” for the marine industry and the power plant pump industry.
More products include marine bearings (rudder, stern tube), container support pads and winch bush. Also, heavyload sheave pulley bush bearings for opening fl oodgates at tidal power plants and shaft sleeve bearings for water drainage pumps for dry docks in the shipyards are among the products.
The maker’s AC low-voltage induction motors range in output from 0.4kW to 500kW (at 220V~660V), while its high-voltage induction motors vary in output from 37kW to 2,500kW (at 690V~13,800V).
The manufacturer’s servo motors and servo drives are widely applicable for robots, injection-molding machines, packaging machines, semiconductor lines, FA systems, and others. Ranging in rated output from 50W to 75W, servo motors feature rapid position/speed control and high-speed operation with low noise. Servo drives passed EtherCAT conformance test assuring compatibilities with EtherCAT based network systems.
Higen Motor has played a key role in the Korean government-sponsored major R&D projects to develop next-generation profi table core products such as robots and electric vehicle motors that are solidly competitive in the global market in terms of price and performance.
Since the fi rm can provide a full range of production consulting from design phase to fi nal product’s application, it can satisfy customers’ changing requirements and off er fast and optimum solutions for any diffi cult problems encountered by customers.
