◇ 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!

CALGAVIN is a group of experts providing solutions to various problems related to heat exchangers. - Optimization of plant operations - Removal of plant limitations - Reduction of required energy For these solutions, CALGAVIN has been thoroughly researching the optimization and improvement of heat exchangers in collaboration with universities and research institutions for over 40 years. By inserting 'hiTRAN', a heat transfer enhancement element, into tube-type heat exchangers, both new and existing, various benefits can be obtained: - Reduction in the number of tubes, weight reduction, and decreased installation area - Reduction in initial costs and installation expenses - Increase in heat transfer coefficients - Decrease in heat transfer area - Maintenance of long-term operation by reducing fouling inside the tubes - Increase in production while reducing energy consumption - Reduction of required energy - Decrease in maintenance costs *For more details about the product, please refer to the catalog or feel free to contact us.

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.*
