Drying without additional energy?
Up to the 1950s, tiles had been dried in open-air dryers without additional energy. Today, approximately 50 to 75 % of the total consumed heat energy is used for drying.
The EcoDry drying system developed by ROTHO can use ambient air economically up to the end of the first drying segment. This allows up to 70% of the previously-required heat energy to be saved. It also results in lower CO2 emissions and the required CO2 certificate.
The subsequent end-drying is carried out using the Xstream quick-drying process. This combination allows for similar drying times and construction areas of conventional dryers. In addition, less aggressive drying with ambient air improves the product quality, particularly with products that were previously difficult to dry.
Low-energy drying is also interesting for existing drying facilities with surplus capacity. The savings which can be made on thermal energy depends on the essential heat from the cooling process emitted from the furnace. Particularly in existing drying chambers with process air ventilators, retrofitting is possible using simple measures and without great risk.
EcoDry Product Advantages:
- Reduced thermal energy consumption by up to 70%
- Reduced CO2 emissions and CO2 certificates
- Improved product quality with difficult to dry brick formats
- Same space requirements and drying times as conventional dryers (in combination with XStream quick drying)
