If concrete is to be used at temperatures of up to minus 15° C,  the sand and gravel silos require heating and the water used for mixing the concrete must also be pre-heated. The Sauter silo heaters run with hot air so that the water/cement ratio is not affected. In continuous operation the plant heats the minerals by 15° C or more. With pre-heated mixing water from the boiler, the concrete temperature can be increased by an additional 8° C. Hot air is blow directly onto the minerals and moves up through the silo, preventing localised heating and condensation.
