This application had a strict height requirement at 70" tall total while also requiring an enthalpy plate, AND dedicated exhaust. We decided to go with a side-by-side layout to bring the height down to the specified limit and optimized the width accordingly. On the EA/RA side, these airstreams are entirely separate and they will never cross. The initial design used Daikin DDPLs, because of the length associated we ended up going with ECM arrays to bring our overall length down.
