KTI cold air plants are specially designed to cool large quantities such as gravel and other aggregates efficiently, quickly and economically during concrete production.

Thanks to the highly efficient technology of the cold air system, no or less ice is needed for cooling. Customers thus save electricity and water. Due to wear-resistant materials, these systems work reliably even under the most demanding conditions. A special air scrubber cleans the air before this is cooled down, thus permanently protecting the plant.

• The prevention or reduction of ice through the use of cold air saves costs for electricity and water, as the technology implemented in a cold air system enables more efficient operation.

• In addition, the cold air system must in operation only during concrete production, while an ice plant is usually in continuous operation for 24 hours to fill the ice store even during the downtimes of the concrete batching plant.

• Cold air systems from KTI are a sensible economic upgrade of existing concrete cooling systems instead of expansion with an ice plant or a chilled water plant.

• The use of cold air to lower the temperature of the aggregates before they are fed into the concrete mixer is the most energy-efficient way to cool concrete economically. This can improve overall efficiency by up to 30%.
