Lummus technology launches the next generation of Breech-Lock high pressure heat exchanger closure

The new breech heat exchanger closure offers exceptional operational performance and underscores Lummus’ commitment to providing innovative products and services throughout the life cycle of refining and petrochemical plants

HOUSTON, June 17, 2022 / PRNewswire / – Lummus Technology, a global provider of value-based process technologies and solutions, announced the launch of its Polarisshutter closure, a new technological upgrade applicable to its high pressure heat exchanger equipment. This advanced shutter latch design offers a number of operational benefits including secure, reliable and safe sealing in all conditions, simplified assembly and easier maintenance.

“The Polaris breech heat exchanger exemplifies our dedication to providing innovation and operational performance for customers requiring new or retrofitted heat exchangers,” he said. Rutger Theunissen, Chief Business Officer of Services and Supplies, Lummus Technology. “The new locking system allows for a wider range of operating conditions, larger unit sizes and capacities, and reduces shutdown times through ease of use, while delivering the high reliability and safety our customers have come to expect from. Lummus “.

To preview this technology and its benefits, Lummus will participate in a live webcast hosted by Hydrocarbon processing On Tuesday 21st June, 10am to 11am CDT. You can join the webcast by registering here.

The Polaris shutter design incorporates two new advanced features that elevate its performance above traditional shutter latches in today’s rigorous operating environments. The Proseal system, a new seal loading design, requires no internal split ring, flange or bolts to simplify fabrication, assembly and disassembly. The load on the seal is efficiently distributed and maintained over a wider range of operating conditions. The ProSeal system further protects components from damage and deformation caused by system disturbances and differential thermal expansion.

Complementing the new sealing system is the ProLock locking system, an advanced fixing mechanism through a special device that is easier and safer to use. The design allows easy access to all threads for maintenance, lubrication and repair and greatly reduces the time for inserting and removing the locking cap.

High pressure exchangers with shutter or screw cap type closures are used in the hydrotreatment industry, mainly for hydrocracking, hydrotreating, lubricating oil, slurry and residue updating treatment. Applications include use in reactor feeds and effluent exchangers, recycle gas exchangers, effluent recuperators and gas recovery exchangers and other applications in gas compression and fertilizer processes.

Lummus Technology has been providing heat transfer equipment to the process and power industries around the world for over 75 years. Specializing in heat transfer systems for critical process environments, Lummus has produced industry-leading technology for combustion heaters, including SRT pyrolysis oven and heat exchangers, including HELIXCHANGERheat exchanger and LALEX Lummus advanced shutter exchanger.
