Replacement Tube Bundles for Heat Exchanger Performance Restoration
Krueger Engineering manufactures replacement tube bundles engineered to restore heat exchanger performance and extend equipment service life.

Engineered Replacement Tube Bundles for Industrial Heat Exchangers
Krueger Engineering manufactures replacement tube bundles, the core of the heat transfer mechanism in a shell-and-tube exchanger. The replacement bundles include tubes, tube sheets, and support elements. Once the efficiency of an exchanger has been decreased due to factors such as fouling, corrosion, and wear, then replacement of the tube bundles becomes necessary. New tube bundles will be utilized to increase the efficiency. Our approach focuses on matching the original exchanger geometry while addressing the conditions that led to performance loss.
We support tube bundle replacement through in-house engineering, fabrication, and aftermarket services. Our team applies thermal modeling using HTRI and mechanical design tools such as PV-Elite and Compress to evaluate performance requirements and ensure proper fit. The replacement tube bundles are manufactured in-house, with processes like precision CNC tube sheet drilling, optimized tube arrangement, and welding.
