Aggregate Heating & Cooling

Cost effective concrete temperature control is available from FESCO Direct. Our aggregate heating and cooling systems provide concrete producers the greatest mix control and allow for extended production hours. Whether producing during the hot hours of the summer or the frozen months of winter, we offer total heating and cooling solutions customized to your concrete plant.

Aggregate Bin Heating System


This aggregate bin heating system distributes heated air to the aggregates through a system of diffusers in aggregate bins heating and drying the aggregates at the same time.

Using hot air reduces corrosion in the hoppers and dries the materials. The efficient hot air diffusers evenly distribute almost 100% of the hot air creating uniform moisture content in sand, and better slump control.

Aggregate Cooling System


Aggregate cooling options may require a wet belt conveyor, sand cooler, or even and ice plant.

Flooded wet belts are a cost effective alternative to a costly on-site ice plant or even a sand cooler. Based on our operational requirement we will develop a cooling system specific to your concrete plant.

Aggregate Heating System at Charge Point


Heating your aggregates as they are being loaded into a bin is a cost effective way ensure you are able to produce concrete even during frozen winter conditions. Using a direct fired steam generator, the aggregate is heated in smaller quantities as it is being loaded into the aggregate bins, typically using a radial stacking conveyor.

Using this system frozen aggregates are quickly heated using dry steam (212°F to 550°F) created by a steam generator connected to the charging hopper. Frozen aggregates are quickly thawed and heated by the dry steam system and then fed into the normal aggregate bins. The heated aggregates retain heat after being loaded into the bin further distributing the heat throughout the aggregate.

This type of system is economical to install and is well suited for high production facilities, facilities that have indoor or enclosed storage, locations that have shorter periods of cold weather, or in conjunction with a bin heating system.
