The "ECO Type Heat Exchanger" that we handle solves problems such as "struggling with leaks in heat exchangers" and "wanting to reduce defect rates." By eliminating the brazed joints through serpentine seamless technology, we minimize the risk of gas leaks. Additionally, by using stepped collars, we maintain the spacing of the fins, improving the contact with the piping and enhancing the efficiency of heat exchange. 【Features】 ■ Reduces the risk of failure ■ Minimizes the risk of gas leaks ■ Maintains fin spacing with stepped collars ■ Improves contact with piping, enhancing heat exchange efficiency *For more details, please feel free to contact us.

Our "microchannel heat exchangers" are recommended for those looking for high-performance heat exchangers. By using flat multi-channel tubes in the heat transfer tubes, the heat transfer area is increased compared to typical heat exchangers of the same size, resulting in improved heat transfer rates. This product is recommended for those seeking high-performance heat exchangers. Please feel free to contact us if you have any inquiries. 【Features】 ■ Improved heat transfer rates due to increased heat transfer area compared to typical heat exchangers of the same size ■ Capable of providing high-performance microchannel heat exchangers compared to standard fin & tube designs *For more details, please feel free to contact us.

The "R-ECO" that we handle is a product designed for companies looking to reduce weight and material costs by changing the heat exchangers for refrigeration to aluminum. Through seamless processing, the risk of gas leakage is reduced, and by increasing the fin pitch, it enables high corrosion-resistant epoxy resin coating, providing excellent corrosion resistance. Additionally, low costs are achievable through customized designs tailored to customer needs and applications. 【Features】 ■ Reduces the risk of gas leakage through seamless processing ■ Enables high corrosion-resistant epoxy resin coating by increasing fin pitch ■ High corrosion resistance ■ Low costs achievable through customized designs tailored to customer needs and applications *For more details, please feel free to contact us.

Our product "A-ECO," which we handle, is recommended for companies considering the miniaturization of equipment using heat exchangers. By switching entirely to aluminum, we achieve weight reduction, and there is no need for painting to prevent pitting corrosion due to the sacrificial corrosion effect from the material composition, allowing us to provide high-density heat exchangers. Customized designs tailored to customer needs and applications enable low costs. 【Features】 ■ Weight reduction is possible by switching entirely to aluminum ■ No need for painting to prevent pitting corrosion due to the sacrificial corrosion effect from the material composition ■ High density ■ Low costs are achievable through customized designs tailored to customer needs and applications *For more details, please feel free to contact us.
