CALGAVIN's "hiTRAN" heat transfer enhancement element - Improving the performance of the tube-type heat exchanger, reducing fouling inside the tubes, and decreasing energy requirements.

Increase and improve the capacity of heat exchangers, reduce fouling inside the tubes! A group of experts dedicated to solving various issues related to heat exchangers. Support from Japanese professionals who are well-versed in processes and heat exchangers!

◇ What is "hiTRAN"? 1. Wire elements intricately woven are inserted into the tubes of the heat exchanger. 2. Various wire materials such as SUS and copper can be used. 3. Compatible diameters: φ6 to φ150mm. 4. Applicable to both "existing" and "new" heat exchangers. 5. Appropriate shapes and densities are selected according to specification conditions. ◇ What are the benefits of "hiTRAN"? 1. Miniaturization of new heat exchangers (e.g., from 4 to 1 pass) ⇒ Reduction in initial costs! 2. Recovery of capacity in existing heat exchangers ⇒ Reduction in running costs! 3. Prevention and reduction of dirt inside the heat exchanger tubes ⇒ Reduction in maintenance costs and shutdown time! 4. Improvement of plant operational capacity ⇒ Reduction in utility costs!

By inserting "hiTRAN" into the tubular heat exchanger, we can reduce fouling inside the tubes and achieve long-term operation!

The CALGAVIN-produced "hiTRAN" is a heat transfer enhancement element designed to improve the performance of heat exchangers, particularly intended for use in tubular heat exchangers. By inserting hiTRAN into the tube, turbulence is generated within the tube, significantly improving heat transfer efficiency. The benefits obtained from the hiTRAN heat transfer enhancement element are as follows: ✓ Improvement and enhancement of heat exchanger capacity ✓ Increase in tube-side heat transfer coefficient (up to 16 times) ✓ Reduction in heat exchanger surface area and weight ✓ Reduction in maintenance costs due to decreased fouling ✓ Energy savings due to reduced energy requirements ✓ Lower maintenance and installation costs As fouling inside the tube increases, the performance of the heat exchanger decreases, leading to more frequent cleaning. This occurs because the flow velocity at the tube wall is slow, allowing dirt to accumulate there. As a result, additional energy is required to restore the performance of the heat exchanger, leading to a decline in production efficiency. Naturally, maintenance costs also increase. Here, we will introduce the mechanism of fouling reduction in the tube by hiTRAN. *For more details, please refer to the materials or feel free to contact us.*

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.
