CALGAVIN's "hiTRAN" / Mechanism for Reducing Internal Contamination

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.*

Digital Agency: "paperlogic can be used as contract documents for the national and local governments."

  • NEW
  • COMPANY

"Electronic contracts for national and local governments are also available with 'paperlogic Electronic Contracts'" In December of last year (2023), we inquired about our service 'paperlogic Electronic Contracts' regarding the 'Law and Orders Related to Regulations on New Business Activities' utilizing the Digital Agency's gray zone resolution system. As a result, we received a response from the Digital Agency stating that 'paperlogic Electronic Contracts' can be used as an electronic record in place of paper contracts for national and local government contracts. "'paperlogic' is endorsed by the Digital Agency" In this inquiry, we received confirmation that 'paperlogic Electronic Contracts' can be utilized as an electronic record in place of paper contracts for national and local government contracts. From now on, you can confidently use 'paperlogic Electronic Contracts' not only for contracts between private companies but also for all types of contracts in local government practices, including administrative contracts and discretionary contracts. For business document digital transformation and electronic contract services, feel free to consult with paperlogic.
