When discharges from furnaces or other high temperature systems are too extreme for normal filtration operations, an air-to-air heat exchanger will lower temperatures to an acceptable level. Installing an air-to-air heat exchanges will adjust the ACFM entering the filter inlet to a temperature within filtration tolerances.

Air-to-air heat exchanges accomplish:

1. Lower temperature media
2. Smaller filter due to reduced ACFM
3. Less footprint and maintenance on smaller equipment

We can set the heat exchanger on a common hopper with the filter saving the cost of another material handling point. The heat exchanger temperature is controlled with a temperature sensor and VFD on the cooling fan. This allows you to control the temperature + - 20° F or less.

For proper operation, our design incorporates a proprietary expansion joint at the cell plate where the tubes connect. The dirty air is directed through the tubes and the cooling air is directed around the tubes. The tube has an inset on the top to prevent wear at the tube inlet.

We have built and installed units for ACFM of 700 to 28,000 and incoming air temperature of 1,000 to 1,600 degrees F, 3,000 ACFM to 38,000 ACFM @ temperature.

We have 25 of these units in service since 1993.
