When mixing concrete at the temperatures down to minus 8º C, the minerals required – gravel and sand – will need heating, and maybe water, too.
Heating Systems – tailored to suit individual demands – are suitable for various types of mineral storage. The use of hot air keeps minerals completely dry, and provides ideal conditions for measuring the amount of water required by the concrete making process. The ratio of water to cement can thus be maintained at a controlled optimal value. And because the gravel and sand are dry, corrosion in the outlet part of a silo will be prevented.

By the heating the minerals alone, Heating Systems are capable of raising the temperature of the concrete by about 15º C. And additional rise of 8º C can be obtained by heating the water. A combined heating effect of 23º C is thus realizable.

An alternative to a fixed installation, Heating Systems for concrete production plant can be housed in a standard container for transport between sites. The weather-proofed container contains an air heater, a water heater, an oil tank, various reservoirs for additives, and automatic controls. The system is supplied to a customer completely prepared for operation.
