Cost reduction through energy saving

RotaVect energy saving rate of 65% to 75%

Among Furnace Juko products, the RotaVect product group has amazing performance with an energy saving rate of 65% to 75% compared to traditional industrial furnaces. Why was it possible to achieve such extreme energy savings?

Traditional furnaces that were large

In the traditional method, many products are lined up on a shelf called a basket and the basket with the products is placed in a furnace to be heated, then the basket with the products is taken out. By doing this, an extra amount of heat is applied to heat the basket, requiring the furnace to be larger to enable the entire basket to be put in. This also requires more time to reach the target temperature and the problem of uneven temperature rising times inside between the top, bottom, left, and right of the furnace occurs. Additionally, even in a furnace that does not use a basket that employs a typical circulation fan, hot air is supplied from the lower part to the upper part of the furnace, and because the temperature rises quickly from the lower work, problems of uneven heating and uneven quality occurs. Since this prevents securing a consistent number of processed products, it becomes necessary to increase the number of products to be processed at one time in order to achieve the target production number, and so conventional industrial furnaces had to be made large.

Elimination of all unevenness with hot air circulation technology

The problems of uneven heating and uneven quality of products have also been dramatically and innovatively improved by Furnace Juko's patented hot air circulation technology. In this hot air circulation technology, the air is first heated by a gas burner, electric heater, etc. then blown directly on the products at high speed with the circulation fan in the furnace. However, the heat is replenished and recirculated and repeatedly heated while the accuracy of the temperature is strictly controlled. A notable feature is the cylindrical guide installed on the hot air outlet side of the circulation fan. This makes it is possible to blow high-pressure pressurized hot air directly on the work at high speed with a consistent air volume, eliminating all unevenness such as uneven temperature rise, uneven heating, and unevenness in quality. Inside the furnaces of Furnace Juko, are shelves made to match the products so the products can be arranged on them, succeeding in eliminating the excess heat generated for the baskets.

Realization of extreme energy-saving that surpasses energy-saving

Furnace Juko's patented hot air circulation technology has made it possible to eliminate all unevenness such as uneven temperature rise, uneven heating, and unevenness in quality, which efficiently eliminates wasted heat treatment and by designing an industrial furnace without the need to use traditional baskets, wasted heat generated for the baskets is completely eliminated. Extreme energy-saving that surpasses energy saving is realized, and by efficiently eliminating wasteful heat, reduction of carbon dioxide emissions, which have become serious environmental problems, have been reduced by a phenomenal 65% to 75% compared to traditional furnaces.
