An air-to-air type of Heat Exchanger that has a low running cost, easy to clean, easy to maintain, and is 100 % reliable for cooling high-temperature fine gases. Its design is compact and modular, easy to install, and economical to run. Added advantage, is it provides clean hot air, which can be used in the process (material drying, etc.) thereby making its operation commercially profitable. The heat exchanger has been designed in such a way that it can be run for 24 hrs.

The Air-to-Air Heat Exchanger reduces both the temperature and the dust loading of the excess gas to the dust collecting system, thereby lowering the gas volume to be handled and increasing the life of the filter bags. This also permits the vent fan to operate at a reduced speed and corresponding lower power consumption.

During upset clinker cooler operating conditions, the Air-to-Air Heat Exchanger aids in the protection of the downstream equipment within the specified design temperature limits. This is accomplished without the introduction of dilution air or water spray systems. In most cooler vent systems where there is no heat exchanger ahead of the dust collector, numerous problems are experienced with burning filter bags, unstable kiln hood draft control, and limited vent system capacity due to the introduction of dilution air. With the Air-to-Air Heat Exchanger, these problems are essentially eliminated.
