Consulting - Specifying Engineer | Recovering waste

Cross-flow heat-recovery cores work similar to enthalpy wheels, but the airstreams flow in an X pattern separated by static plates of heat-transfer media. Static cores can be enthalpy or sensible-only depending on the heat-transfer media used for the plates. Mechanical codes don't allow heat recovery from exhaust that is considered hazardous.
