This is an introduction to a case where iron exceeding the standard value was detected in drinking water just before the completion of a new hospital construction project. One example of detecting iron is corrosion of steel pipes. However, this is unlikely in a new construction site, so an investigation of the water supply system revealed that there was a mistake in connecting the water supply pipes and the utility water pipes. Additionally, our company has also identified foreign substances using advanced equipment and a rich database. [Overview] ■ Issue - Detection of iron exceeding the standard value in drinking water just before the completion of new construction ■ Solution - Conducted an investigation of the water supply system - Determined that there was a mistake in connecting the water supply pipes and the utility water pipes [Be cautious of such troubles at new construction sites!] ■ Water may stagnate in the pipes for a long time, leading to the possibility of general bacteria and TOC (total organic carbon) exceeding standard values ■ If the water source is well water, components from the soil may leach out, causing iron, manganese, and fungi to exceed standard values.

We would like to introduce a scientific approach to investigating the causes of refrigerant leaks in welded plate heat exchangers. In the visual inspection, no foreign objects or blockages were found at the cold water inlet and outlet sides, and no external deformations were observed. 【Investigation Overview】 ■ Visual Inspection ■ Air Tightness Test ■ Dissection Investigation ■ Water Quality Test 【Verification Results】 Based on the deformation characteristics of the plates, it is determined that the cause was the expansion of cold water inside the plates due to freezing. Once freezing occurs inside the plates, the circulation flow rate in that area decreases, leading to repeated freezing and increased deformation. In areas other than the deformed sections, no impact was observed on the plate materials, which are stainless steel and copper solder. Therefore, it is concluded that the cause of the gas leak was an incidental issue due to the removal of deposits from previously frozen areas. As a countermeasure, regular water quality management and maintenance are being implemented for improvement. *For more details, please refer to the PDF document or feel free to contact us.

The outdoor unit had some white substance attached to it, and the company contacted us stating that "it cannot be removed by conventional regular cleaning with high-pressure water." Upon investigation, it was found that hard well water was used in the spray system, causing scale to precipitate and adhere to the fins of the outdoor unit's heat exchanger. Additionally, it was discovered that excessive cleaning with high-pressure water had caused the fins to bend, and the combination of scale and bent fins was blocking the airflow, leading to the high-pressure anomaly. As a solution, we carried out a cleaning process. During this, we used a special cleaning agent to avoid damaging the aluminum fins. The bent fins were also returned to their normal state, resolving the issue. [Case Summary] ■ Issues - The outdoor unit with a cooling spray system experienced an abnormal shutdown due to a rise in high pressure during the summer. - It could not be removed by conventional regular cleaning with high-pressure water. ■ Solutions - Cleaned with a special cleaning agent to avoid damaging the aluminum fins. - Restored the bent fins to their normal state. *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to a case study that improved the combustion efficiency of a kerosene boiler and achieved cost reduction. In a certain factory, a measurement of the exhaust gas from a kerosene boiler that had been used with its initial settings revealed an air ratio of 1.8, which was causing an increase in fuel costs due to decreased combustion efficiency from excess air. We reported the current situation to the customer and proposed a solution to adjust the air ratio during combustion to 1.3. Our company conducted real-time exhaust gas measurements simultaneously with inspections by the boiler manufacturer. As a result, efficient adjustments became possible, and regular measurements are now conducted to confirm the proper operating conditions of the boiler. [Case Summary] ■ Issues - An air ratio of 1.8 caused increased fuel costs due to decreased combustion efficiency from excess air. ■ Solutions - Proposed a solution to adjust the air ratio during combustion to 1.3. - Enabled efficient adjustments and confirmed the proper operating conditions of the boiler. *For more details, please refer to the PDF document or feel free to contact us.

In recent years, awareness of environmental issues has increased, and wastewater regulations have become even stricter. However, it is also true that many cleaning companies still discharge wastewater that exceeds regulatory limits. This wastewater issue is considered one of the significant challenges for factories. In response to the request to "collect all wastewater generated during air conditioner cleaning," our company has been working on improving various collection methods. As a result, we have developed dedicated wastewater collection vehicles and wastewater collection kits, establishing a robust system that allows us to collect wastewater from air conditioner parts cleaning as well. Additionally, we have collaborated with manufacturers to develop optimal cleaning agents, implementing measures to minimize the amount of cleaning wastewater generated. Our company aims not only to clean air conditioners but also to pursue environmentally conscious cleaning practices. [Case Overview] ■ Challenge - To collect all wastewater generated during air conditioner cleaning ■ Solution - Developed dedicated wastewater collection vehicles and wastewater collection kits, establishing a robust system to collect wastewater from air conditioner parts cleaning. *For more details, please refer to the PDF materials or feel free to contact us.

The Labor Safety and Health Act mandates that workplaces using regulated substances such as organic solvents and specific chemicals in quantities above a certain level, such as factories, must conduct regular work environment measurements. There are penalties for violations. Our company has certified work environment measurement specialists who conduct measurements on-site and evaluate the environmental conditions of the workplace. For example, a hospital requested measurements due to concerns that the indoor formaldehyde concentration might be high. The measurements revealed that the formaldehyde levels indeed exceeded the standard values. As a result, we proposed the installation of local exhaust ventilation systems in areas with high concentrations. Additionally, we recommended and implemented proper storage methods for chemicals in storage areas, which led to a reduction in formaldehyde levels and overall improvement of the indoor environment. 【Case Summary】 ■Issue - There are concerns that the indoor formaldehyde concentration may be high, and measurements are requested. ■Solution - Proposed the installation of local exhaust ventilation systems in areas with high concentrations. *For more details, please refer to the PDF document or feel free to contact us.

In a factory where drainage inspection and maintenance of the wastewater treatment facility are separately contracted, our company is responsible for the drainage inspection. In one factory, there was a tendency for the wastewater quality to exceed the standards. As a result, under the administrative penalty system, there was an obligation to pay a specified fee depending on the degree of exceeding the standard values. Therefore, the managing company requested the maintenance company for improvements. The maintenance company then implemented improvement measures and conducted a drainage inspection (separately from our company) to prove the effectiveness of these measures, submitting the inspection results to the managing company. However, the results did not reflect the actual situation (with suspended solids SS at 0 mg/L, indicating no suspended matter at all), and the data was unreliable. By the way, the data from the drainage inspection conducted by our company around the same time was near the standard value (200 mg/L) and yielded different results. Considering such cases, it is deemed effective to conduct cross-checks by a third-party organization like ours when drainage inspections are not separately contracted.

We would like to introduce examples of refrigerant ammonia recovery and decontamination work associated with the repair and removal of ammonia refrigeration systems. The number of refrigeration systems using ammonia as a refrigerant, which existed in large numbers 30 to 40 years ago, has decreased due to aging and removal, leading to a reduction in engineers capable of maintenance. Our company has a proven track record in recovery and decontamination associated with the removal of various facilities such as large cold storage warehouses and ice factories, and we have engineers capable of handling complex systems. Using our unique decontamination equipment, we can carry out decontamination work safely, quickly, and with consideration for the environment. 【Features】 ■ Engineers capable of handling complex systems ■ Not subject to the Manufacturing Act of the High-Pressure Gas Safety Act, no prior notification to authorities required ■ Quick response possible even in cases requiring urgent repairs ■ Implementation of safety measures within the system to ensure that repairs, removals, and demolition work can be carried out safely *For more details, please refer to the PDF document or feel free to contact us.
