姫路エコテック List of Products and Services

The Himeji Ecotech plate-type heat exchanger cleaning system has been jointly developed with a major power company and features a cleaning system with two processes: "chemical cleaning" and "blow cleaning." By frequently performing chemical cleaning, cost-effectiveness is improved, and blow cleaning allows for the removal of foreign substances that cannot be addressed by anti-fouling technology without opening the heat exchanger. 【Features】 ■ No risk of gasket deterioration, damage, or leaks ■ Significantly reduced downtime for the equipment ■ Increased frequency of chemical cleaning can enhance cost-effectiveness ■ Contaminants are removed during construction, using methods that consider the water environment *For more details, please refer to the PDF document or feel free to contact us.

Plate-type heat exchangers need to have their gaskets replaced regularly, but opening the heat exchanger on-site for cleaning and gasket replacement requires a significant amount of effort. If you entrust us with the entire heat exchanger or just the plates, we will handle everything from cleaning to gasket replacement on your behalf. The gaskets we offer are equivalent products, making them very reasonably priced compared to genuine ones. 【About the factory maintenance process】 ■ Incoming inspection ■ Gasket removal ■ Chemical immersion ■ High-pressure water cleaning, etc. Before consulting the manufacturer, please feel free to contact us first! We also sell equivalent gaskets, so don't hesitate to reach out. *For more details, please refer to the PDF document or feel free to contact us.

The "Small Tube Cleaning Work" is a project aimed at improving the heat exchange function and reliability by cleaning the small tubes of the condenser in power plants. The small tubes of the seawater cooling system in power plants not only experience a decrease in heat exchange efficiency due to slime, purple mussels, and barnacles, but also cause pinholes in the tubes due to the attachment of marine organisms, erosion from changes in flow velocity, and deposit attacks occurring in the surrounding area. Unfortunately, routine cleaning with sponge balls and backwashing alone cannot completely remove the attached organisms. Thorough cleaning is necessary during regular inspections. In our small tube cleaning work, we remove dirt using "Bullet Cleaning," as well as "Spin Brushing" and "Hydro Bit Cleaning." We also recommend "Small Tube Inspection." 【Small Tube Cleaning Work】 ■ Bullet Cleaning ■ Spin Brushing ■ Hydro Bit Cleaning ■ Small Tube Inspection *For more details, please refer to the PDF materials or feel free to contact us.

The "Mitti Mouse Cleaning Machine" is a handheld cleaning device that performs powerful mechanical cleaning of the inner surface of heat exchanger tubes. The tube sizes that can be cleaned range from an inner diameter of 8mm to 125mm. It can remove dirt and hard silica scale (calcium carbonate) that has clogged the inner surface of the tubes without the need for large cleaning machines. 【Features】 ■ Four types of rods that can be selected according to tube size ■ An inline type oiler is included with the air hose, allowing direct connection to the air piping instead of a lubricator ■ Removes dirt and hard scale that has clogged the inner surface of the tubes without the need for large cleaning machines ■ Less likely to damage the tubes compared to jet cleaning *For more details, please refer to the PDF document or feel free to contact us.

"Spin brushing cleaning" is a mechanical cleaning method that removes scale from the inner surface of small tubes using a flexible wire shaft. The cleaning device is very compact and does not require a large space like a jet vehicle. Various cleaning tools can be attached to the tip of the shaft, and cleaning water is sprayed from the center of the shaft while rotating the cleaning tool to remove dirt from the inner surface of the tube through friction. [Features] - Compatible with heat exchangers with small inner diameters (φ6.4mm and above) - Capable of cleaning U-shaped sections - Reduces wastewater treatment volume - Less likely to damage tubes compared to jet cleaning *For more details, please refer to the PDF document or feel free to contact us.

The condenser's small pipes are exposed to corrosive and dirty environments. To improve these conditions, it is necessary to review the operation of the condenser, but the operational methods vary depending on the water intake conditions and equipment. In the "Model Condenser Test," we will set various operational methods in advance to investigate and propose appropriate operational methods. 【Water Flow Conditions】 ■ Iron ions: concentration, time, frequency ■ Ball cleaning: type, number of cleanings, frequency ■ Chlorine injection: concentration, time *For more details, please refer to the PDF document or feel free to contact us.

• Electrical Equipment Testing

We offer a "Leak Detection Service for Condenser Cooling Pipes." The detection work is carried out while operating the condenser in a single-ended mode, and the pressure control valve is opened for about 10 seconds, during which helium is dispersed. It is necessary to set up scaffolding in the water chamber on the helium dispersion side. Inspections can be conducted for purposes such as performance evaluation, investigation of corrosion causes, verification of cleaning effects, confirmation of operational conditions, and comparison of the performance of various pipe materials. 【Example of Implementation】 ■ Number of cooling pipes: Approximately 6,500 (per water chamber) ■ Required time: 2 to 3 hours ■ Number of detected leaking pipes: 1 *For more details, please refer to the PDF document or feel free to contact us.

• Structural Survey

The inner surface of the small tubes of copper alloy heat exchangers using seawater as cooling water needs to form a protective film to improve corrosion resistance. Generally, a method is adopted where iron ions are injected into the cooling water to form a protective film of iron hydroxide on the surface of the small tubes. However, excessive injection of iron ions can lead to a decrease in thermal efficiency, and insufficient injection of iron ions will not provide adequate corrosion resistance. Therefore, our company conducts monitoring surveys to confirm that an appropriate initial iron film has been formed. [Method] - A bypass line is installed on the piping at the outlet side of the condenser of the circulating water pipe, and a sample tube is attached. - Seawater is passed through the bypass line simultaneously with the startup of the circulating water pump. - Regularly conduct polarization resistance measurements and visual observations to assess the status of iron film formation. *For more details, please refer to the PDF document or feel free to contact us.

Our company has jointly developed a cleaning system with a major power company that incorporates two processes: "chemical cleaning" and "blow cleaning." This system eliminates the need to disassemble the plates, thereby reducing the downtime of the equipment compared to conventional cleaning methods. By frequently performing chemical cleaning, we achieve higher cost-effectiveness, and by utilizing blow cleaning, we can remove foreign substances that cannot be addressed by anti-fouling technology without opening the heat exchanger. 【Features】 ■ The downtime of the equipment is shorter than that of conventional cleaning methods. ■ Frequent chemical cleaning increases cost-effectiveness. ■ There is no risk of gasket deterioration, damage, or leaks. ■ Contaminants are removed during construction, using methods that consider the water environment. ■ Foreign substances that cannot be addressed by anti-fouling technology can be removed without opening the heat exchanger. * We will propose suitable cleaning agents and methods for your situation through a free cleaning test. * For more details, please refer to the PDF document or feel free to contact us.

Our company has entered into a dealership agreement with Conco Services, which holds a significant share in the United States for the cleaning of heat exchanger tubes, and we are introducing the Conco system aimed at removing tough deposits from heat exchanger tubes. We provide total management from the sale of cleaners to cleaning work and measuring tube contamination, helping to reduce costs. [Features] - The cleaner is inserted into the tube and pushed out with water pressure to clean the tube. - The scraper-type cleaner removes hard scale and stubbornly attached marine organisms. - The H-brush type cleaner is suitable for removing soft scale. *For more details, please download the PDF or feel free to contact us.
