Since 1990, Dunn has maintained a library of electronically archived drawings of equipment engineered, fabricated or modified by the company.  

Customers planning to have existing equipment modified or replaced can save considerable time and expense by contacting us to utilize this valuable resource.

Customers can also use this resource when replacement parts are needed. Rather than looking for old files, drawings, or material lists, or worse yet , waiting to take measurements when the equipment is opened in the field, they should contact Dunn.  

In addition to complete exchangers and tube bundles routinely fabricated, the following is a partial list of components that may also be purchased from us:

To order drawings or replacement parts please contact us at drawingarchive@dunnheat.com and include in the subject line your company name and the equipment number for which drawings or parts are needed.   In the body of the email please include all name plate information available and indicate the specific drawings or parts needed and any other information relevant to the request.
