Our Products leading to energy and resource saving, great improvement of economic effect.
Ultra lightweight calcium silicate thermal insulator Keical Ace Super Silica, has been developed corresponding to recent requirements, that is, thermal insulator is needed, which is more lightweight and stronger, and keeps the heat better, and withstands the heat more excellent.
Keical Ace Super Silica suppresses the diffusion calorific value and improves the fuel efficiency to contribute to energy and resource saving.
Keical Ace Super Silica is the top thermal insulator evaluated all over the world.
Ultimate thermal insulator applicable to a wide variety of industrial fields from thermal and nuclear power plants to regional air coditioning.
Keical Ace Super Silica
Keical Ace Super Silica is mainly composed of xonotlite crystal (6CaO·6SiO2·H2O) and its working temperature is 1000°C specified JIS No.1.
Not only the maximun working temperature is higher than that of JIS No.2, but also Keical Ace Super Silica shows no contraction in the mwdium temperature range (500°C or less), where the operation frequency is particularly large.
This ensures safe operation.
Keical Ace Super Silica WP
If the rain water splashes during construction work under the working conditions of 70°C to 150°C, like thermal insulation of the heavy oil tank, the water is difficult to vaporize and rust is produced, causing the thermal insulation performance to lower.
To prevent rain wqater during construction work, water-repelling material WP (Water Proof)-T (water-repelling of entire portion) is prepared.
Elbow Ace
In the normal construction work of piping elbows, the thermal insulation tube is cut corresponding to the elbow parts and these cut tubes are jointed.
To shorten the construction work period and reduce the machining loss, Elbow Ace is available that the elbow parts are prefabricated.
When needing Elbow Ace, please contact us early.
Mirror Ace
This product is prefabricated according to the curved surface of the end plate of various pressure vessels.
Not only can the construction man-hour be greatly reduced, but also the gap is narrow and the use of jointing material is minimized, reducing industrial waste.
Keical Excel
Keical Excel uses the radiative heat shielding agent and is a product that suppresses the thermal conductivity, which increases like secondary curve as the temperature increases.
Additionally, the physical properties of Keical Excel are almost the same as those of the normal product.
Keical Excel is specially developed for high-temperature use.
Please use Keical Excel corresponding to your needs.
Recycal
Calcium silicate heat insulator, once used, becomes industrial waste and is landfilled.
We bring these industrial waste to the factory, regenerate it again as a calcium silicate heat insulator, and deliver it to the discharge source.
