[INQ. NO. 2208M13] WOOAM SUPER POLYMER Co., Ltd. is a company that was founded in 1996, and specializing in manufacturing PTFE heat exchangers and heaters for the use of chemicals.


In recognition of the performance and stability, the product is being supplied to many companies nationwide and exported to a number of countries including China, Taiwan, the USA, and European nations.


WOOAM is planning to take the lead in the industry by producing its own differentiated and high-quality products including PTFE heat exchangers, chemical in-line heaters, PTFE tanks, quick couplers, degassers, bead-less tubes, static mixers.

PTFE heat exchanger is designed for heating and cooling ultra pure (single ppt) and highly corrosive fluids.
PTFE heat exchangers have excellent corrosion resistant qualities, these products are available in a wide variety of capacities and sizes to meet virtually any type of process heating and cooling a highly corrosive and high purity fluids. The perfect tube sheet structure applying patented fusion-welding technology makes it possible to endure high temperature and pressure (maximum use temperature and pressure: 90°C@5Kg/Cm2G).


As the wetted surface of chemicals is structured PTFE solid, it causes no contamination. The efficiency lasts for a long time as the fouling phenomenon (in which foreign substances are generated and stacked up on the tube surface) seldom occurs.


The quality has been recognized after being supplied to ultra-pure (12N, single PPT grade) processes and electro grade chemical manufacturing processes.


In-line heaters are divided into two types: immersion and indirect. ID heaters are manufactured in indirect-method structures to safely heat up IPA, solvent, and other chemicals that have risks of explosion. Meanwhile, IM heaters usually used for SC-1, sulfuric acid, etc.

Plate & Frame Heat Exchanger

June 15, 2022 by Leave a Comment
https://korean-machinery.com///inquiry

INQ. NO. 2205M16] LHE’s plate heat exchanger consists of heat transfer plates for exchanging heat, gaskets that seal the fl uid fi xed and movable covers, fluid inlet & outlet port nozzles, carrying & guiding bars and tightening bolts.
The key element of the plate heat exchanger is a hydraulically-pressed metal plate with a thin rectangular plate, gasketed at the edges.
Several heat plates are overlapped to form a single pack and bolted between the fixed and movable covers. The gasket installed on the heat plate prevents the mixture of the two fluids and leaks out of the plate pack to the surroundings.

Each pair of adjacent heat transfer plates forms a channel and hot fl uid and cold fl uid fl ow within that channel. While two fl uids pass through the channel hot fl uid transfer some of its heat energy to cold fl uid in the other channel through the thin plate. As a result, it reduces the temperature of the hot fl uid and increases the temperature of the cold fluid.
LHEBloc’s main component is the plate pack, panels, panel gaskets, upper & lower heads, columns and support.
LHEBloc is manufactured by inserting a welded plate pack into a rigid rectangular frame secured with bolts and has the advantage of providing a large heating area even in a very small space. The frame ensures mechanical strength while also insolating the fl ow paths of the two fluids.

If necessary, each flow path is fitted with a welded or detachable baffle. Four side carbon steel panels with nozzles attached have pipe connections and the panels can be lined with the same material as the heat plate. The plate, baffle and panel liner are made of stainless steel, titanium, etc. A pair of heat plates is welded along both ends.
The spiral heat exchanger is made of two concentric channels in which spacer pins are welded to create the gap of the channel. In order to meet the customer’s requirements and operating conditions, channel spacing and channel width are determined, and the overall flow rate allowable pressure drops, and the particles contained in the fl uid are considered.

Heat Exchanger

September 9, 2019 by Leave a Comment

https://korean-machinery.com///inquiry[INQ. NO. 1909M01] This refers to various heat exchangers such as condenser, fan & shroud, evaporator, heater core, etc. It is a core product that converts warm air into cold air or cold air into warm air. Its condenser is a product that is made of aluminum material, which is small in size, light in weight and high in efficiency.
There are two types of wave fin and louver fin. The former has low heat-exchange efficiency, but is advantageous for removing foreign substances. Mainly applied to products, the latter has high heat-exchange efficiency but it is difficult to remove foreign substances, so it is mainly applied to general vehicles. Fan&shroud is a condenser. It is a component that is mounted on the product to allow direct air cooling. It is excellent in mounting and durability with low noise, miniaturization and high performance.
There are options to set up products according to position. In the case of EVA, Louver FIN is applied to increase the heat transfer area and to provide excellent cooling performance. Lastly, Heater Core products are also made of aluminum to enhance their miniaturization, light weight and excellent heat exchange efficiency.

Heat recovery steam generator

September 3, 2015 by Leave a Comment

[INQ. NO. 1508M01] BHI is a world-leading supplier of heat exchangers, including heat-recovery steam generators, which have been awarded the World Class Product of Korea 2012 by the Ministry of Trade, Industry and Energy of Korea.

Heat-recovery-steam-generatorhttps://korean-machinery.com///inquiry With astonishing achievements in HRSG (Heat Recovery steam generator)fin tube coating technology, BHI has coated HRSG fin tubes with porcelain enamel, which have been co-developed by KOSPO and Ujin. This coating technology will prevent corrosion at dew points and enhance the durability of HRSG fin tubes, without compromising the heat-exchanging capabilities. Shin-Incheon project is the first HRSG in the world with enamel-coated fin tubes, and BHI is hoping to apply this technology further to other projects.

Utilizing LNG fuel, HRSG operates the gas turbine used for existing thermal power generation, collects high-heat waste with a recovery device, and operates the steam turbine. HRSG is an environment-friendly power generating device that efficiently produces electric power by a two-step process. Hence, it is considered to be mandatory equipment for a combined thermal power plant.

Based on self-developed technologies, BHI produces high-quality products that minimize pressure loss and maximize heat transfer. BHI contributes to energy saving and environment protection by efficiently recycling high-temperature exhaust gas energy.

Range of Heat Exchangers

November 30, 2012 by Leave a Comment

Heat Exchaners - LHELHE Co., Ltd is a heat exchanger manufacturer producing a wide range of heat exchangers such as plate heat exchanger, spiral heat exchanger, oblong heat exchanger, plate coil heat exchanger, bloc heat exchanger, etc.
Plate Heat Exchanger, one of the main products of LHE Co., involves bringing two substances at different temperatures close to each other so that one either heats or cools the other. And it uses heat transfer plates fitted with gaskets that seal off each channel from the next and direct the fluids into alternate channels. Oblong (Shell & Plate) Heat Exchanger combines good features Plate Heat Exchanger and Shell & Tube Heat Exchanger. Oblong Heat Exchanger is designed to be very compact compared with Shell & Tube Heat Exchanger.

The Spiral Heat Exchanger is constructed of two long metal strips rolled around and open split center forming two concentric spiral passages, one for each fluid. The transferred counter flow enables heat exchange for tiny temperature difference, and thus the spiral type is optimized for saving energy. The remarkable feature of LHE Bloc heat exchanger is to enable operation under higher pressure and temperature due to greater mechanical strength by welded structure without using interpolate rubber gaskets.

LHE’s heat exchangers are now exported to countries such as Saudi Arabia, China, Japan, Canada and the U.S.A. In the nation, they are supplied to major corporate customers including POSCO, Samsung Electronics, STX Offshore & Shipbuilding, LG Chemical, Daewoo Shipbuilding & Marine Engineering, Hyundai Engineering & Construction, GS Engineering & Construction, etc.
