Better surface finish and less porosity. Reducing chemical additives reduces the gas that is generated.
More dimensionally accurate castings. Thermal reclamation creates expanded silica sand grains which do not go through the same expansion as new sand during every pour. In steel foundries this can limit or eliminate the need for iron oxides, zircon and chromite sands.
Far less odor and smoke in the foundry during pouring because less chemical binder is needed.
Less grinding and welding of castings is required. With fewer chemical additives and a superior quality of sand grain, casting defects such as finning and burn-in are reduced.
The TES-SAN thermal reclamation plant is the possibility to minimize the part of new sand as well as the quantity of used sand to be landfilled. In this way the acquisition costs for new sand and the disposal.

Thermal reclamation offers better surface quality and reduced porosity while minimizing chemical additives. It enables more dimensionally accurate castings. Through thermal reclamation, sand with superior crystal structure, even better than new sand, is obtained with every casting. This eliminates issues like gas permeability and similar problems.

In steel foundries, it limits or eliminates the need for iron oxides, zircon, and chromite sands. Additionally, thermal reclamation results in much less odor and smoke during casting, as less chemical (resin, binder) is used in the sand obtained through the process. Castings require less grinding and welding. Fewer chemical additives and superior-quality sand particles eliminate casting defects.

With the TES-SAN thermal reclamation plant, it is possible to significantly reduce the amount of new sand used, leading to up to a 95% reduction in new sand costs.

Other Advantages of Thermal Reclamation:

Fewer defects in castings

Better casting surface

Lower labor costs

Less waste

Reduced chemical requirements
