Cross Reference to vintage products

DP Hand Connection Diagrams

Caution is required when crossing old products to new. Cross references should be viewed as functional, not necessarily dimensional replacements. Our goal is to help you find the best available solution. Sometimes the best available solution is very good. Sometimes it presents a real challenge to the technician to make it fit.

Helpful Tip: Many older unit numbers and coil numbers reflect nominal capacity in BTU/hr. New products are defined by cfm.

Example: The old 60-HBAX was rated based on a nominal 60,000 BTU, or 5 ton. Today’s HBB60 is based on cfm (6000 cfm, or 15 tons).
