Since 
Since In addition to our standard heat exchanger product range, FRHE also supports more demanding and specialized applications requiring advanced metallurgy, replacement engineering, reverse engineering and urgent fabrication support.
Our experience extends beyond standard supply, allowing us to assist clients who require technically suitable, commercially practical and site-compatible heat exchanger solutions for critical plant operations.
Exotic Alloy Heat Exchangers
Titanium, Duplex, Super Duplex & Exotic Stainless Steel Heat Exchangers
FRHE is able to support the design and fabrication of heat exchangers using advanced and corrosion-resistant materials for demanding industrial applications.
Our material capabilities include, but are not limited to:
- Titanium Grade 2
- Duplex Stainless Steel
- Super Duplex Stainless Steel
- Stainless Steel 304 / 316 / 316L
- High-grade and exotic stainless steel materials – SS310, 254SMO etc
- Material selections based on process duty, corrosion requirement and client specification
These materials are commonly considered for applications involving corrosive media, seawater, chemical processes, sour service, high chloride environments, aggressive condensates and other demanding operating conditions.
FRHE understands that exotic material fabrication requires proper control over material selection, welding procedure, cleanliness, dimensional accuracy, inspection and quality documentation. Where applicable, we are able to support projects involving special material requirements, pressure-retaining components, tube-to-tubesheet joints, headers, tubesheets, shell assemblies and heat exchanger replacement units.
Typical applications include:
- Titanium heat exchangers involving high corrosive media / sea water
- Duplex and Super Duplex heat exchangers
- High temperature process heat exchangers and waste heat recovery units (Economizers)
- Corrosion-resistant replacement tube bundles
- Custom heat exchangers for chemical, petrochemical, marine, oil & gas and process industries
Why This Matters
For critical heat exchanger applications, material selection is not only a matter of cost. It directly affects corrosion resistance, mechanical strength, operating reliability, maintenance frequency and long-term plant safety. FRHE works with clients to provide practical material solutions that balance technical suitability, delivery time and commercial feasibility.
Complete Thermal & Mechanical Design
Engineered Heat Exchanger Design Support, FRHE is able to support clients from early-stage enquiry through to final heat exchanger design and fabrication.
Our design support may include:
- Thermal design review
- Heat transfer area evaluation
- Mechanical design considerations
- Material selection review
- Pressure part design support
- Replacement design based on available site information
- Dimensional matching for existing installation
- Design optimization for performance, maintainability and fabrication practicality
For replacement projects, clients may not always have complete original design information. In such cases, FRHE can work with available drawings, site measurements, operating data and process requirements to develop a practical replacement solution.
Our objective is to deliver heat exchangers that are not only technically suitable, but also practical for installation, operation, maintenance and long-term use.
Replacement of Obsolete OEM Heat Exchangers
1-to-1 Replacement for Existing or Discontinued Heat Exchangers
Many industrial plants operate heat exchangers that were originally supplied many years ago by OEM manufacturers. Over time, the original manufacturer may no longer support the unit, spare parts may become difficult to obtain, or replacement cost and lead time may become commercially unattractive.
FRHE is able to support the replacement of obsolete or aging OEM heat exchangers by developing a replacement unit based on the existing installation requirement.
Our replacement approach focuses on:
- Maintaining existing overall dimensions where required
- Matching existing nozzle location and orientation
- Maintaining site installation compatibility
- Reducing piping modification work
- Improving performance where required
- Upgrading material selection where suitable
- Providing a practical plug-and-play replacement solution
This is especially useful for plants that require minimum shutdown duration and do not wish to modify existing piping, supports or surrounding equipment arrangement.
Reverse Engineering of Heat Exchangers
Replacement Based on Existing Unit, Site Measurements or Limited Drawings
FRHE is able to assist clients with reverse engineering requirements where the original drawings are incomplete, outdated or unavailable or where upgraded performance is required due to new process / production requirements.
Our reverse engineering support may include:
- Site dimensional verification
- Measurement of existing heat exchanger units
- Review of old drawings or dimensional sketches
- Identification of main construction features
- Review of nozzle orientation and installation interface
- Development of replacement drawings
- Proposal of suitable material and construction improvements
- Fabrication of replacement unit based on agreed dimensional requirements
Reverse engineering is particularly useful for aging equipment, legacy OEM units, emergency replacement projects and cases where the end user requires a practical replacement without major plant modification.
Fast-Track Emergency Fabrication
Urgent Heat Exchanger Replacement for Critical Plant Operation
FRHE understands that heat exchanger failure can directly affect plant reliability, production continuity and shutdown planning. For urgent requirements, we are able to provide fast-track fabrication support subject to material availability, technical review and project complexity.
Our fast-track support may include:
- Urgent review of enquiry documents
- Priority engineering assessment
- Expedited material sourcing
- Accelerated fabrication planning
- Replacement based on existing dimensions
- Coordination for urgent inspection and delivery
- Practical technical support for shutdown or emergency replacement cases
For emergency fabrication, early confirmation of key information is important, including drawings, photos, dimensions, operating conditions, material requirements, nozzle details and delivery expectations. FRHE will always aim to provide the fastest practical delivery while maintaining proper workmanship, inspection and quality control.

CORROSION PROTECTION COATING
Protective Coating for Offshore, Marine & Corrosive Environments
FRHE is able to support heat exchanger applications requiring protective coating systems such as Heresite coating, particularly for operating environments where corrosion resistance and long-term surface protection are important.
Heresite coating is commonly considered for heat exchangers exposed to harsh atmospheric or corrosive environments, including offshore platforms, marine installations, coastal plants, chemical plants, petrochemical facilities, refineries, wastewater treatment areas and other aggressive industrial environments.
This coating option may be suitable for applications where the heat exchanger is exposed to:
- Offshore and marine atmosphere
- Salt-laden air
- Coastal or high-humidity environments
- Corrosive industrial surroundings
- Chemical vapour exposure
- Process areas with higher corrosion risk
- Equipment requiring additional external protection
For heat exchanger applications, Heresite coating can be considered for components such as coils, finned surfaces, casings, frames, air cooler components and other exposed areas, depending on the project requirement, operating condition and coating suitability.
Why This Matters
In offshore, marine and corrosive environments, heat exchangers are often exposed to aggressive external conditions that can accelerate corrosion, reduce service life and increase maintenance frequency. A suitable protective coating system helps provide additional corrosion protection, improves durability and supports longer-term equipment reliability.
FRHE can assist clients in reviewing whether Heresite coating or an alternative protective coating system is suitable based on the operating environment, material of construction, temperature, process condition and project specifications.
