As symbolized by the recent abnormal weather, the effects of increasing greenhouse gas have a significant impact on the global environment.
In order to protect the global environment, we have to choose as much as possible the means that do not place a burden on the environment in our daily activities as well as in our corporate activities.

In order to fulfill our corporate social responsibility and become a foundation for survival, we proposed a switch from steam heaters that rely mainly on a fossil energy to the self-regulating heater that use electrical energy with less environmental impact, and we aim to help you.

In addition, the effects of water leakage from piping are not limited to the loss of property value, contamination of the human body due to harmful substances, and adverse effects on the surrounding environment, and the cost and labor required for recovery are beyond imagination.

  • Pipeline anti-corrosion measures to ensure safety against leaks from pipelines buried underground for decades or more
  • A water leak detection system that quickly detects leakage that can lead to serious loss or contamination, as a result of being left unattended for a long time, resulting in a large amount of leaks.

We will contribute not only to sales of products, but also to engineering for the above technologies by reducing the burden on the global environment.
Through corporate activities, we will increase the value for all stakeholders and contribute to society.

Experiment module

In November 2010, we set up an equipment for freezing experiments at our affiliates Kashiwa Tech site. From the adjacent monitor room, it is possible to monitor and record the temperature states and progress of piping, containers, and other objects within the freezing room. By using state-of-the-art digital recorders, it is also possible to process data on computers. From freeze protection to maintaining process heating, various verification tests are carried out focusing on self-regulating heating cable due to electrical heating. We will continue to strive to create a new application.
