The "U-tube type heat exchanger" is a heat exchanger made by bending steel pipes into a U shape, as a replacement for channel-type turn bends. The steel pipes can be selected from carbon steel, stainless steel, or special heat-resistant steel depending on the temperature and gas composition. To achieve high heat transfer performance, the heat source gas flows perpendicular to the tubes on the outside, while the preheated gas is passed through at high speed to enhance its cooling effect. High-temperature preheating is possible up to a heat source temperature of 950°C and a preheated gas temperature of 750°C. Additionally, by installing multiple units in parallel within the flue, it can accommodate large flow rates. 【Features】 ■ Heat exchanger with U-bent steel pipes ■ Uses rolled steel pipes for the heat exchange section, suitable for gas-to-gas applications ■ Performance similar to channel-type ■ Achieves high heat transfer performance by ensuring the heat source gas flows perpendicular to the tubes on the outside *For more details, please refer to the PDF materials or feel free to contact us.

The "Channel-type Heat Exchanger" is a gas-to-gas heat exchanger that uses rolled steel pipes in the heat exchange section. The steel pipes can be selected from carbon steel, stainless steel, and special heat-resistant steel based on temperature and gas composition. To achieve high heat transfer performance, the heating gas flows outside the pipes in a direction perpendicular to the tubes, while the preheating gas is passed through at high speed to enhance cooling effects. The tube block is available in vertical (top suspension) and horizontal types. 【Features】 ■ Gas-to-gas heat exchanger using rolled steel pipes in the heat exchange section ■ Achieves high heat transfer performance by directing the heating gas to flow perpendicularly to the tubes ■ Capable of high-temperature preheating with heating source temperatures up to 950°C and preheating gas temperatures up to 750°C ■ Supports large flow rates by installing multiple units in parallel within the flue *For more details, please refer to the PDF document or feel free to contact us.

The "COMPAC G-L" is a plate-type heat exchanger for gas-liquid applications made from steel plates (t1.2 to t4.5). It can be manufactured in a wide range of sizes, from small to large. The pressure resistance is suitable for steam applications up to 10 kPa and for liquid applications up to 30 kPa. Since the elements are flat plate type, they are less prone to dust accumulation, allowing for the production of heat exchangers with minimal performance degradation and pressure loss. Additionally, maintenance is easy. We can design units from small to large capacity tailored to your needs, including material, configuration, dimensions, and auxiliary equipment combinations. 【Features】 ■ Gas-liquid type using steel plates ■ Pressure resistance: 10 kPa for steam, 30 kPa for liquid ■ Lightweight, compact, and high-performance, similar to the "COMPAC G-G type" ■ Less prone to dust accumulation, resulting in minimal performance degradation and pressure loss ■ Easy maintenance *For more details, please refer to the PDF document or feel free to contact us.

The "Radiation Type Double Cylinder Heat Exchanger" is a gas-gas heat exchanger that utilizes high-temperature heat source gas (above 800°C). It can heat preheated gas up to 650°C by using high-temperature heat source gas. The heat source gas flows inside the inner cylinder, which is installed concentrically, while preheated gas flows at high speed between the inner and outer cylinders. Gas radiation is due to the CO2 and H2O gases in the heat source gas, making it suitable for utilizing high-temperature gas due to the high concentration of these gases. 【Features】 ■ Utilizes high-temperature heat source gas (above 800°C) ■ Capable of heating preheated gas up to 650°C ■ Equipped with numerous fins on the outer surface of the inner cylinder to enhance the cooling effect of the preheated gas ■ Suitable for utilizing high-temperature gas *For more details, please refer to the PDF document or feel free to contact us.

The "Radiation Type Cage Heat Exchanger" is a gas-gas heat exchanger that utilizes high-temperature heat source gas (over 800°C). It can heat preheated gas up to 650°C using high-temperature heat source gas. Instead of a double cylindrical inner tube, it uses tubes on the heat transfer surface. Heat source gas flows inside the inner tube, while preheated gas flows at high speed inside the tubes. Gas radiation is due to CO2 and H2O gases in the heat source gas, making it suitable for utilizing high-temperature gas due to the high concentration of these gases. 【Features】 ■ Utilizes high-temperature heat source gas (over 800°C) ■ Can heat preheated gas up to 650°C ■ Uses tubes on the heat transfer surface instead of a double cylindrical inner tube ■ Suitable for utilizing high-temperature gas *For more details, please refer to the PDF document or feel free to contact us.

The "Shell & Tube Heat Exchanger" is a type of heat exchanger that arranges numerous steel tubes within a cylinder and passes heat source gas through these tubes. Baffle plates are installed to ensure that the preheated gas flows directly into the tubes. It is possible to prevent dust accumulation by passing significantly dust-laden gas (e.g., from sewage sludge treatment facilities) through the steel tubes at high speed. High-temperature preheating can be achieved with heat source gas temperatures of up to 850°C and preheated gas temperatures of up to 600°C. 【Features】 ■ By passing dust-laden gas (e.g., from sewage sludge treatment facilities) through the steel tubes at high speed, dust accumulation can be prevented. ■ High-temperature preheating is possible with heat source gas temperatures of up to 850°C and preheated gas temperatures of up to 600°C. ■ Self-supporting tower design requires minimal installation space. ■ Can also be used as a gas cooler by flowing cooling water outside the tubes. *For more details, please refer to the PDF document or feel free to contact us.

The "COMPAC Wave Plate Type" is a heat exchanger designed for gas-to-gas, gas-to-liquid, and liquid-to-liquid applications, made by combining thin steel plates (t0.6) that have been processed with wave patterns on both sides. The elements are specially processed with wave patterns to exhibit high heat exchange performance. Since no gaskets are used, there is no leakage due to gasket deterioration, allowing for long-term operation without maintenance. Additionally, by combining elements and element blocks, it can accommodate capacities ranging from small to large. 【Features】 ■ Exhibits high heat exchange performance ■ Pressure resistance up to 30 kPa ■ Each element has a fully welded structure, maintaining complete airtightness ■ No leakage due to gasket deterioration, allowing for long-term maintenance-free operation ■ Capable of handling capacities from small to large *For more details, please refer to the PDF document or feel free to contact us.

The "COMPAC G-G Thick Plate Type" is a gas-gas plate heat exchanger that uses thick plates (t3.0 to t6.0). It contributes to the longevity in cases where corrosion of the elements is likely to progress, such as in waste incineration plants, sludge treatment facilities, and industrial waste treatment facilities. In facilities with a high amount of dust, combining it with an optional scraping duct removal device can significantly reduce dust clogging. Depending on the amount and nature of the dust, maintenance can also be reduced to about once a year. 【Features】 ■ Gas-gas type using thick plates ■ Minimal performance degradation over time due to dust adhesion, with low pressure loss ■ Easy to clean ■ Wider element pitch (flow path width) compared to thin plate types, allowing for the production of products that are less likely to clog with dust *For more details, please refer to the PDF document or feel free to contact us.
