Heat Exchangers Engineered for Corrosive & Critical Plant Environments
ATX designs and fabricates Titanium, Tantalum, and Zirconium heat exchangers based on actual process conditions, operating environments, and long-term corrosion requirements.
Heat Exchangers Engineered for
Corrosive & Critical Plant Environments
Selecting appropriate materials and configurations for heat exchangers requires careful evaluation of process conditions, operating environments, and long-term operational risks.
With extensive hands-on experience in fabricating specialty non-ferrous metals, ATX goes beyond manufacturing to provide practical engineering judgment on material selection and structural configuration.
Our approach is grounded in actual service conditions, ensuring reliable performance and durability in corrosive and critical plant environments.
Heat Exchanger Types Manufactured by ATX
Shell & Tube Heat Exchanger
A proven shell and tube heat exchanger design engineered for high-pressure and high-temperature process conditions, recognized as the most widely used configuration in plant industries and capable of handling diverse process media across a wide range of pressures and operating temperatures.
Proven & Widely Adopted Fabrication Reference
U-Tube / Fixed Tube Sheet Type
Designed to accommodate thermal expansion and complex operating conditions, this configuration is selected for corrosive and high-temperature process applications where structural stability and maintenance considerations are critical.
Thermal Expansion–Driven Fabrication Reference
- Representative structural configurations of shell & tube heat exchangers
- Selected based on thermal expansion characteristics and maintenance approach
Coil / Immersion Type
A compact heat exchanger configuration designed for direct installation inside tanks and reactors, optimized for space-constrained layouts and continuous exposure to corrosive or aggressive process fluids.
Space-Constrained Immersion Fabrication Reference
- A configuration installed directly inside tanks or reactors
- Applied in space-constrained or highly corrosive environments
Air Cooled Heat Exchanger
A large-scale heat exchanger system engineered for continuous operation in high-capacity industrial and energy-related processes, utilizing ambient air for heat dissipation in plant environments with limited or restricted cooling water availability.
Water-Constrained Plant Fabrication Reference
- An air-cooled configuration that dissipates heat using ambient air
- Applied in plant environments where cooling water use is restricted
Custom-Designed Configuration
Custom-engineered heat exchanger configurations developed for process conditions where standard designs are not suitable, tailored to specific operating requirements, materials, and plant environments.
Non-Standard Process Fabrication Reference
- Applied to processes where standard configurations are not suitable
- Non-standard heat exchanger forms configured to meet specific process conditions
Why ATX Heat Exchangers
Proven delivery record in chemical and plant environments for over 35 years
We have a long-standing track record of supplying equipment to chemical plant environments where corrosion resistance and long-term operational stability are required, with numerous units delivered over extended periods.
Fabrication-focused in-house control and consistent execution system
Key fabrication processes such as forming, welding, and testing are performed in-house to minimize quality variations between processes and maintain consistent results.
Materials are directly sourced and managed, and the entire process—from fabrication and inspection to delivery—is carried out within a single, integrated workflow.
Experience in plant equipment certification and regulatory compliance
In addition to domestic statutory inspections, we have project experience meeting fabrication and quality management requirements in accordance with various international certification standards.
We provide non-destructive and quality inspection arrangements aligned with customer requirements, either under our own control or through third-party inspection agencies.
Materials We Work With
Ti Titanium
A high corrosion-resistant material widely used in seawater, chlorine-based, and high-salinity environments. ATX has experience in processing various titanium grades and fabricating heat exchangers.
Ta Tantalum
A specialty metal applied in strong acid and extreme chemical processes, capable of withstanding 30% hydrochloric acid at 200°C and 95% sulfuric acid at 200°C. Solid or Lined Construction for Cost Optimization
Zr Zirconium
A specialty metal that exhibits more stable corrosion behavior than titanium under conditions where oxidizing media are present. It is applied in environments where material stability is critical, such as the nuclear field. Solid or Lined Construction for Cost Optimization
Nb Niobium
Applied to complement the durability of high corrosion-resistant structures due to its ability to form a stable oxide film even in high-temperature, highly corrosive environments.
Ni Nickel
Materials that maintain mechanical stability even at high temperatures, showing excellent corrosion resistance in strong alkaline and certain reducing chemical environments.
