Four Rules For Air-To-Air Energy Recovery Units

These units can save energy, but only if the technology is installed and operated correctly.
The application of energy recovery units allows for the ability to do total heat recovery and recover both sensible and latent heat from an exhaust air stream, using that heat to pre-condition outdoor air required for building ventilation.
