Heat Exchangers
From pilot scale to commercial scale production, our custom fabricated heat exchangers provide the necessary heat transfer requirements, along with the corrosion resistance for the demands of your chemical or pharmaceutical production. Our alloy heat exchangers are constructed of Tantalum, Zirconium and Niobium and our exchangers with Silicon Carbide construction integrate well in complete process systems with Glasteel® and fluoropolymer-lined technologies due to similar corrosion resistance.

Pfaudler Heat Exchanger Technology
Pfaudler was the first to fabricate equipment from stainless steel (1926), Tantalum (1942) and Zirconium (1946) and continue to do so today. Over the years we have developed many innovative fabrication techniques to ensure the quality and integrity of our corrosion resistant equipment
Benefits of our Heat Exchanger Technologies
Process Design Know-How
Our experienced process engineers review each application and use simulation software to design a heat exchanger specifically for each process.
Fabrication Expertise
We have over 70 years of practical experience.
High Product Quality
Our all-welded design for tantalum and zirconium construction eliminates leaks as verified using dye penetrant and gas leak testing.
Peace of Mind
We provide “tell-tale” ports that can be used to monitor any process leakage on the back side of our linings as an indication of weld integrity during operation.
Variety of Corrosion Resistant Materials
Our Tantalum, Zirconium, Niobium, Glasteel® and Silicone Carbide materials of construction provide the widest degree of protection for corrosive applications.
Construction codes
We provide construction as per major pressure vessel codes such as ASME, TEMA, PED, AD Merkblatter, CRN and China SQL Codes.
Process Simulation and Design
We custom engineer each heat exchangers using Apen and HYSYS software. We also use 3D CAD software to design the exchanger which provides full visual understanding of the exchanger for design review, ensuring piping layout and future maintenance planning.
Materials Engineering
Our engineers carefully review each application to select the proper material for construction for the corrosive application. They will also define the most economical design for the heat exchanger, which typically means locating the process on the shell side when the process allows and utilizing Glasteel® or fluoropolymer lined steel shells rather that expansive reactive metal shells or bonnets.
Reactive Metal Tubes with Alloy Shell
For corrosive tube side heat transfer, built with reactive metal tube bundle. The corrosive process is on the tube side with reactive metal, Glasteel® or fluoropolymer-lined bonnets and carbon steel shell side for the utility.
Reactive Metal Tubes with Glasteel® Shell
For corrosive shell side condensing or evaporation, built with reactive metal tube bundle. The corrosive process is on the shell side with reactive metal, Glasteel® or fluoropolymer-lined shell and carbon steel bonnets for the utility.
GlasSiC®
For corrosive applications, built with silicon carbide tube bundle and either Glasteel® or fluoropolymer lined tubesheets. The corrosive process can be on the tube side or shell side with Glasteel® or fluoropolymer lined bonnets or shells provided.
