Topics

Off-site production for higher efficiency

We are working on off-site production where piping, peripheral and other components are installed at a location other than the installation site (off-site) before installing HVAC systems on site.
The integrated equipment and facilities are delivered to the site, which helps reduce the workload on site, shorten the construction period, maintain higher safety, and reduce the burden on workers.

Recycled CFCs to reduce environmental load

CFCs, used as a refrigerant in HVAC systems, have greenhouse effects that cause global warming and are feared to have an impact on climate change. TOTECH is working with Kankyosoken Co., Ltd. to properly collect, recycle, and sell CFCs. By providing high-quality recycled CFCs, TOTECH aims to ensure a stable supply of refrigerants, while contributing to the effective use of resources and reduction of environmental impact.
