[Service] Cause investigation through foreign matter analysis

[Service] Cause investigation through foreign matter analysis

Leave the analysis of foreign substances to us! Are there any foreign substances coming from tap water or scattered from the air conditioner?

We offer a "Cause Investigation through Foreign Substance Analysis" service. Are there any foreign substances (such as black or green particles) coming from tap water, settling or floating in tanks, dispersing from air conditioners, clogging filters, or accumulating in ceilings? After discussing the occurrence of foreign substances, we analyze them using various devices to identify the substances. Please feel free to consult us when you need our services. 【We handle the following types of foreign substances】 ■ Foreign substances coming from tap water (such as black or green particles) ■ Foreign substances settling or floating in tanks ■ Foreign substances dispersing from air conditioners ■ Foreign substances clogging filters ■ Foreign substances obstructing pipes ■ Foreign substances accumulating in ceilings *For more details, please refer to the PDF document or feel free to contact us.

[Verification Case] Investigation of the Cause of Refrigerant Leakage in Welded Plate Heat Exchangers

[Verification Case] Investigation of the Cause of Refrigerant Leakage in Welded Plate Heat Exchangers

Clarifying the cause of 'freezing and expansion' in four steps! Introduction of scientific approach verification cases.

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.
