Custom Heat Exchanger Manufacturers in Alberta and BC
Custom Design and Fabrication
At Enermax, our core strength lies in the design and fabrication of high-performance custom heat exchangers built to exact client specifications. We engineer each unit using advanced tools such as AutoCAD, HTRI, ASPEN, Compress, DesignCalcs, SolidWorks, and NASTRAN, ensuring optimal thermal performance and mechanical integrity.
Fabrication Excellence for Heat Exchangers
All fabrication of our heat exchangers adheres to strict American Society of Mechanical Engineers (ASME) and Tubular Exchanger Manufacturers Association (TEMA) standards.
As leading heat exchange manufacturers, we work with an extensive range of materials suited to demanding industrial services, including carbon steel, stainless steel, Hastelloy, titanium and chrome-moly alloys.
Our ASME-certifications include the ‘U’, ‘S’ and ‘R’ stamps:
- The ‘U’ and ‘S’ stamps authorise us to design and build new custom heat exchangers to ASME Section VIII Division 1 and ASME Section I standards.
- The ‘R’ stamp enables us to perform repairs and alterations on existing heat exchangers when required.
At Enermax, we manufacture a wide variety of heat exchanger types, including air-cooled, shell & tube and hair-pin configurations. They are all engineered for efficiency, durability and long-term reliability.
Custom Heat Exchanger Repair and Maintenance
In addition to new fabrication, Enermax offers expert repair and maintenance services to help extend the lifespan of your existing heat exchangers and ensure continuous operation. While custom design and build remains our core focus, our team is certified to perform repairs and alterations under our ASME ‘R’ stamp. Everything we do is backed by meticulous testing and quality assurance processes. Every repaired unit is rigorously inspected to ensure it meets or exceeds industry standards for safety, reliability, and performance.
Advanced Engineering and Design Capabilities
Our engineering process is the foundation of every custom heat exchanger we produce. We solve complex thermal and mechanical challenges by leveraging a sophisticated suite of design and analysis software. Each project begins with a thorough analysis of the client’s operational parameters and technical requirements. Using tools like HTRI and ASPEN for thermal design and rating, we model and simulate heat transfer performance to ensure the proposed design meets or exceeds performance targets.
For mechanical design and stress analysis, we utilize Compress, DesignCalcs, SolidWorks, and NASTRAN to validate the structural integrity, material suitability, and compliance of every component. This integrated approach ensures that each custom-engineered heat exchanger provides not only optimal thermal efficiency but also long-term mechanical reliability, even in demanding industrial environments. Our design capabilities are fully compliant with ASME and TEMA standards, reflecting our commitment to technical excellence.
Fabrication of Custom-Engineered Heat Exchangers
Enermax is a premier fabricator of custom heat exchangers, engineered and built to precise client specifications for a wide range of industrial applications. Our custom fabrication services rely on facilities that are equipped to handle diverse materials and complex designs, ensuring the highest quality standards are met throughout the manufacturing process.
All new fabrication is governed by our ASME ‘U’ and ‘S’ stamp certifications, authorizing us to build pressure vessels and power boilers to ASME Section VIII Div. 1 and ASME Section I codes. We specialize in the following types of heat exchangers:
- Shell & Tube Heat Exchangers: Custom-designed for various process conditions, from high-pressure and high-temperature applications to corrosive service environments. We fabricate to all TEMA classes (C, B, R), ensuring the mechanical design is perfectly matched to the operational duty.
- Air-Cooled Heat Exchangers (Fin-Fan Coolers): Engineered for reliable performance in applications where water cooling is impractical or unavailable. Our designs focus on maximizing cooling efficiency while minimizing power consumption and footprint.
Our material expertise includes carbon steel, various grades of stainless steel, Hastelloy, titanium, chrome moly alloys, and other specialized materials required for challenging service conditions. Every weld, component, and final assembly is subject to rigorous quality control and testing procedures to guarantee compliance with all applicable codes and client requirements.
Ensuring Quality: From Fabrication Floor to Final Shipment of Heat Exchangers
Supporting the Full Lifecycle of Your Equipment
While our primary focus is the engineering and fabrication of new equipment, Enermax provides services to support the full lifecycle of your heat exchangers. We understand that operational needs evolve and that existing assets must be managed effectively.
Repair and Alteration
Under the authority of our National Board ‘R’ stamp, we are certified to perform expert repairs and alterations on existing heat exchangers and pressure vessels. Whether addressing damage, wear, or a change in process requirements, our engineering team can develop and execute a repair plan that restores the unit’s integrity and performance in full compliance with original code standards.
Replacement and Upgrade Services
Enermax can support the replacement of aging or damaged units as required. Our team of heat exchanger manufacturers can design and fabricate direct, in-kind replacements that match the footprint and connection points of the original unit, minimizing downtime and installation costs. Alternatively, we can engineer and manufacture upgraded units with improved thermal performance, enhanced material composition, or a design better suited to current operating conditions. This capability ensures our clients have a clear path for asset renewal, backed by the same engineering rigor as our new-build projects.
