Concrete Aggregate Heaters

Keeping aggregate at a consistent temperature throughout is essential. This is especially challenging during the coldest months of the year. The solution? A concrete aggregate heater from R.W. Martin Process Water. 

The "water" in our name is a bit misleading in this instance though. That's because the Sioux Aggre-Flo® aggregate heater uses a dry heat to prevent the formation of ice and frozen chunks in both fine and coarse aggregates. This maintains the quality and consistency of the aggregate because it doesn't introduce any additional moisture into the mix. 

Make sure your concrete aggregate keeps flowing throughout the winter with a Sioux Aggregate Bin Heater from R.W. Martin Process Water!
