Here is a case study of our solar thermal water heater. To install the collector and tank on the roof, there were concerns about the weight burden on the roof and the potential for bacteria to develop in the water pipes. Since only the collector is installed on the roof, it does not put a burden on the roof. 【Case Overview】 ■Challenges - Weight and burden on the roof - Is the circulating water kept clean? - Can warm water be used at night? - Will the pipes freeze in winter? - Is there enough hot water available? *For more details, please refer to the related links or feel free to contact us.

We would like to introduce an example of our manufacturing of reference tanks for liquid meter inspections. The volume reference device "stainless steel reference tank for liquid meters" can be produced in sizes of 50L, 100L, and 200L. The stainless steel reference tank is used for the calibration of water meters, hot water meters, and heat meters. *For more details, please refer to the related links or feel free to contact us.

• Processing Technology

We would like to introduce a case where we received a consultation from a food processing company and updated their long-used iron thawing tank to a highly corrosion-resistant stainless steel one. There was a request to convert the thawing tank for large fish, such as frozen tuna for canned food, to stainless steel. We updated it to highly corrosion-resistant stainless steel, proposed improvements to the thawing process, and shortened the thawing time by using a method that sprays water from below the tank, reducing the amount of water needed for thawing, thus achieving cost reduction and improved operational efficiency. 【Case Overview】 ■Challenges - Convert the thawing tank for large fish, such as frozen tuna for canned food, to stainless steel. ■Results - Adopted high-strength and relatively inexpensive duplex stainless steel. - Shortened thawing time using a method that sprays water from below the tank. - Reduced the amount of water needed for thawing, achieving cost reduction and improved operational efficiency. *For more details, please refer to the related links or feel free to contact us.

• Processing Technology

We would like to introduce a case study where the use of NSSC-190 in the hot water system's storage tank has achieved excellent pitting corrosion resistance and crevice corrosion resistance. The storage tank in the hot water system was made of enamel but lacked durability. By using NSSC-190 in the hot water system's storage tank, we have achieved excellent pitting corrosion resistance and crevice corrosion resistance. 【Case Overview】 ■Challenge - The enamel used lacked durability. ■Result - By using NSSC-190, we achieved excellent pitting corrosion resistance and crevice corrosion resistance. *For more details, please refer to the related links or feel free to contact us.

• Processing Technology

Our company is a professional in the welding technology of special stainless steel. We design and manufacture solar water heaters using special stainless steel welding technology. The processing of special stainless steel is a technology developed in collaboration with major companies by our predecessor company. Currently, we manufacture solar thermal water heaters as OEM products utilizing that technology. 【Services】 ■ Stainless steel tanks ■ Standard tanks for liquid manufacturer inspections ■ Solar thermal water heaters ■ Photovoltaics *For more details, please refer to the related links or feel free to contact us.
