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
