in THE MAIN WALL
Does anyone have information on ratings for 1930's flat top water/steam Crane radiators? We bought the Book by Dan Holohan "E.D.R....", but it did not inventory the Crane radiators. We have a house restoration in New Mexico and are re-using the old Cranr radiators in a new hydronic system. We are battling it out with the Contractor and plumber and desparately need the rating information for these radiators. Anybody out there?

    Do they look like normal free-standing sectional radiators?

    If so, ratings were quite standardized and you should be able to find something similar in EDR

    The "Burnham Slenderized" beginning on page 190 is good for most of the especially compact tube-type radiators. Dimensions (height and width of sections) might not be exactly the same as others, but a close size match will mostly likely have the same EDR. Again, manufacturers were remarkably good about using standardized ratings for similar products.

    The US Capitol beginning on page 136 is good for "traditional" thin-fin tube rads. Section height and width (as well as EDR) are nearly identical among this type.

    You can differentiate between these two general types by measuring the width of an individual section and comparing to dimensions in the book. The "slenderized" are significantly narrower.

    Thank you so much for your input... I will forward this to our engineer and Plumber...

    I also found out that "Shafter Bros. Inc." in Montreal, Quebec, assembles new radiators with old parts from post 1935 radiators...they have rating information available there for "New Style Radiators" that works as well... looks like they may be using "Corona"? radiator parts? www.oldcastironradiators.com

    Am almost positive it's of the typical thin-fin tube variety--not the "slenderized".

    If so, section width should be 2½".

    Definitely not \"Slenderized\"

    which by the way was Burnham's name for their midget or "small-tube" radiators.

    That Crane is a "large-tube" type. The section width (center-to-center) should be 2-1/2 inches. The ratings for the American Corto, National Aero, U.S. Capitol and similar units can be used for your Cranes.
