PAL Certified Quality
Technical Overview
Our U-Tube Bundle heat exchangers feature a single tubesheet and U-bent tubes. Because only one end is fixed to the tubesheet, the tubes can expand and contract freely in response to large temperature swings, completely eliminating thermal stress on the shell-tube joints.

Key Engineering Features
Zero Thermal Stress
The free-floating U-bend design accommodates extreme thermal expansion without causing fatigue or cracks in the tube joints.
Easy Shell Cleaning
The entire tube bundle can be pulled out of the shell, giving full access for mechanical cleaning and water jetting of the shell interior.
Economical Design
Using a single tubesheet reduces manufacturing complexity and material costs, making it a highly cost-efficient solution.
