NOTES:
1. All dimensions are approximate. Certified dimensions are available on request.
2. For compact water boxes (shown above), determine overall unit length by adding water box depth to tube sheet length.
3. Water nozzles can be located on either end of unit. Add 1/2" (13 mm) to nozzle length for flanges connections.
4. To determine overall height, add 7/8" (22 mm) for isolators.
5. Use of motors with motor hoods may increase overall unit dimensions.
