l The Functional Principle of Rotary Heat Exchangers

The combination of heat and humidity recovery of rotary heat
exchangers is a highly efficient energy-saving technology. It is equally successful when used for comfort climate range, industrial plants or marine applications. It is common to have energy recovery rates between 70-90%. Air pressure drops through such exchangers of lower 200 Pa are usually economically sensible.

Supply and exhaust air each pass through half of the wheel in counter flow directions. The rotor matrix is a rotating transfer media. It temporarily takes up the heat from the warm air stream and releases it in the colder air stream. The hygroscopic / sorptive coating of the storage matrix brings the additional advantage of recovering moisture.

Typical summer application is dehumidification of warm and humid
supply air to reduce the energy consumption of the down stream cooling equipment. During winter operation this feature recovers moisture from the exhaust air to reduce the humidification load.
