Helixchanger®
Turn Up the efficiency
Shell-and-tube heat exchangers (STHXs) play a vital role in refinery and process applications; however, conventional segmental baffle designs often face challenges such as high shell-side pressure drop, flow-induced fouling, vibration issues, and reduced thermal efficiency. These limitations can impact operational performance and increase maintenance requirements.
In helical baffle heat exchangers, the baffles are arranged at an inclined angle along the shell length, creating a continuous spiral flow path across the tube bundle. Designed in accordance with Lummus technology principles, this configuration promotes uniform fluid distribution, reduces dead zones, minimizes fouling, and enhances overall heat transfer performance. Our helical baffle heat exchangers are engineered to significantly reduce pressure drop and mitigate flow-induced vibration while improving thermal efficiency. With superior fouling resistance, optimized flow characteristics, and extended service life, they are a preferred solution for high-performance applications in petrochemical, refinery, and process industries
Rod Baffle Heat Exchangers
Stable Design Superior Heat Transfer for gas-to-gas applications in PP or PE plants
A rod baffle heat exchanger is a specialized type of shell-and-tube heat exchanger in which conventional solid plate baffles are replaced with a system of longitudinal rod grids extending along the entire shell length. This innovative configuration significantly reduces shell-side pressure drop while minimizing stagnant or dead-flow zones within the tube bundle. The rod grids are arranged in an alternating pattern to provide uniform tube support, ensuring effective flow distribution and superior resistance to flow-induced vibration.
Rod baffle heat exchangers designed in accordance with Novolen technology are widely used in polymer, petrochemical, and chemical processing industries, where high reliability, low fouling, and optimized thermal performance are critical.
Cryogenic Heat Exchangers
Where Extreme Cold Meets Smart Engineering
Our cryogenic heat exchangers are specifically designed to meet the extreme demands of cryogenic processing at temperatures as low as –163°C. They provide precise and efficient thermal control for liquefied gases, ensuring stable operation under severe low-temperature conditions. Engineered for structural integrity, thermal stability, and robust performance, these exchangers play a critical role in LNG, gas separation, and air liquefaction plants.
Our solutions are developed to withstand harsh cryogenic and offshore environments, supporting efficient LNG transfer, heating, and regasification processes, particularly onboard LNG & FSRUs. We have extensive experience in supplying exchangers manufactured from special materials of construction, like stainless steel including Alloy 825 and other superior grades, to ensure superior corrosion resistance, mechanical strength, and long-term reliability in demanding applications.
High Pressure Heat Exchangers
Strength in Pressure, Precision in Heat Transfer
A high‑pressure D‑type heat exchanger is a specialized shell‑and‑tube heat exchanger designed to handle elevated operating pressures and temperatures. The “D‑type” designation refers to a divided‑flow shell configuration defined by TEMA standards. This design improves heat transfer efficiency by directing fluid flow in a way that reduces bypassing and enhances turbulence, which increases thermal performance. Because it is built for high‑pressure service, the exchanger typically incorporates reinforced tube sheets, thicker shells, and closures such as breech‑lock systems to withstand demanding conditions. Materials of construction often include alloy steels, duplex stainless steels, or nickel alloys, chosen for their strength and corrosion resistance. These exchangers are widely used in petrochemical plants, fertilizer units, gas processing facilities, and power generation, where reliable performance under severe operating conditions is critical.
Low Fin Heat Exchangers
Finned for Better Performance
A low‑fin tube heat exchanger is a shell‑and‑tube type exchanger that uses tubes with small, integrally rolled fins on their outer surface. These fins increase the external surface area of the tubes, which enhances heat transfer efficiency, especially when one of the fluids has a low heat transfer coefficient such as gases. Because the fins are part of the tube wall itself, they are mechanically strong, resistant to vibration, and durable under high‑pressure and high‑temperature conditions. This design allows for compact equipment that delivers better thermal performance compared to plain tubes, making it ideal for applications like petrochemical plants, refrigeration systems, power generation condensers, and chemical process cooling. In short, low‑fin tube heat exchangers provide a reliable and efficient solution where improved heat transfer and reduced equipment size are critical.
High Flux Heat Exchangers
Maximum Heat Transfer, Maximum Performance
A high‑flux tube heat exchanger is a specialized type of shell‑and‑tube exchanger that uses tubes with an enhanced surface treatment or coating to significantly improve heat transfer performance. The “high‑flux” tubes are typically manufactured by bonding a porous metallic layer or sintered surface onto the tube wall, which increases the effective surface area and promotes better boiling or condensation of fluids. This design is especially useful in applications where one side of the exchanger involves phase change (like boiling or condensing) and where maximizing thermal efficiency is critical. Because of their superior heat transfer capability, high‑flux tube exchangers allow for more compact equipment, reduced weight, and lower operating costs compared to conventional exchangers. They are widely used in industries such as petrochemicals, power generation, refrigeration, and LNG processing, where reliable performance under demanding thermal loads is essential.
Condensers
Advanced Condenser Design for Optimized Heat Transfer
A condenser is designed specifically to condense a vapor into liquid by transferring heat to a cooling medium. It consists of a cylindrical shell containing a bundle of tubes, with one fluid flowing inside the tubes and another fluid flowing outside them within the shell. In condenser duty, the vapor (such as steam, hydrocarbon vapours, or refrigerants) typically flows on the shell side, while cooling water or another coolant flows through the tubes. As the vapor loses heat to the coolant, it condenses into liquid, which is then collected and removed.
These exchangers are widely used in power plants (steam turbine exhaust condensers), petrochemical and chemical plants (hydrocarbon vapor condensation), and refrigeration systems. Their advantages include high reliability, ability to handle large heat loads, and flexibility in design for different pressure and temperature conditions. Materials of construction are chosen based on the fluids involved, often carbon steel, stainless steel, or copper alloys for good thermal conductivity and corrosion resistance.
