I came across this very interesting unit last year and had forgotten the URL. I bumbled into it again and decided to post the info before it sinks beneath the waves again. It is amongst the most interesting designs I have come across.

This is an Enthalpy Wheel ERV with a claimed maximum efficiency of 96%, (real efficiency is likely in the 80% range). This is pretty good, because cross-flow HRVs have a real efficiency close to 60%.

From looking at the documents below, it would not be a casual undertaking to DIY an enthalpy wheel HRV.

Here's a Link to the User Manual.

Here's a link to the Installation Manual.

Link to Dealer Brochure

Here's a link to the company.

They seem to run about $1600 bucks, with one currently on ebay at $1,270 OBO.
