Keep Your Concrete Plant Fully Operational During Winter

Steam is commonly used to accelerate the curing of concrete products at precast plants and for heating aggregates and limited amounts of water at both ready mix and precast concrete plants. FESCO Direct offers cost-effective, high-performance steam generators from Sioux® that outperform conventional boilers and are ideally suited for small to mid-sized concrete producers, as well as larger operations.

Forced Air Aggregate Heating System
A forced air aggregate heating system from FESCO Direct.

The Aggre-Flo forced air aggregate heating system is designed to heat fine and coarse aggregates to mitigate ice and frozen chunks over winter months. The whole bin is heated to a constant temperature with dry heat that brings no extra moisture into the aggregate. Concrete producers can keep aggregates flowing from bins and get 100% consistent batch quality even through the coldest months.

This forced air aggregate heater lives up to the Sioux reputation and delivers on its promise to keep aggregates flowing through the winter.
