KROTECT™
KROTECT™ is an insulation material that has very low thermal conductivity and demonstrates excellent thermal insulation performance. It is used in steel manufacturing and industrial furnaces, as well as in household fuel cells (ENE-FARM).
KROTECT™ has the characteristics of lower thermal conductivity and higher strength than conventional materials.

Presentation Materials and inquiries for KROTECT™
KROTECT™ can reduce energy loss by improving insulation performance, and thereby decreasing heat released to the outside from equipment such as furnaces.

*KROTECTTM (Low thermal conductivity type) 3mm is applied.
*Please note that the values obtained from this simulation are all predictions, and are not guaranteed to be effective.
KROTECT™ can make fuel cell products smaller and lighter because it can maintain conventional insulation performance while reducing the thickness of the insulation material.

By miniaturizing fuel cells, they can be installed even in narrow spaces, expanding the options for installation locations.
Additionally, weight reduction leads to improved workability and reduced labor during installation and maintenance, as well as lower costs associated with downsizing.
Presentation Materials and inquiries for KROTECT™
We estimated of CO₂ reduction based on the amount of heat dissipation in an industrial furnace operating 24 hours a day, 365 days a year using fossil fuels, comparing three scenarios: No insulation, Using conventional products, KROTECT™.
As a result, we found that by using KROTECT™ with its high insulation performance, we can reduce CO₂ emissions by approx. 58 tons per year compared to conventional products.
Comparison of CO₂ emission reduction between our conventional product and KROTECT™
We obtained calculation results showing that by using KROTECT™ with its high insulation performance, CO₂ emissions can be reduced by approx. 58t per year compared to conventional products.*
* As our own calculation, we estimated the CO₂ reduction amount based on factors such as heat dissipation in each case (no insulation, using conventional products, and using KROTECTTM (Low thermal conductivity type)) assuming industrial furnaces operating 24 hours a day, 365 days a year, with fossil fuel.
