The Breech-Lock Heat Exchanger features an innovative closure system that enables rapid bundle removal and installation without hot work, reducing maintenance downtime by up to 75%. This patented technology combines the reliability of traditional flanged exchangers with unprecedented ease of maintenance.
Bundle extraction in 2-4 hours vs. 24-48 hours for conventional flanged exchangers. No hot work required for closure removal.
Breech-lock closure provides positive mechanical locking with 360° uniform sealing, suitable for pressures up to 300 bar.
Reduced labor costs with simple bolt-free closure mechanism. Maintenance can be performed by standard crew without specialized tools.
Lower total cost of ownership through reduced downtime, minimal spare parts inventory, and extended gasket life.
Up to 300 bar (4,350 psi)
-50°C to +400°C
200 mm to 2,400 mm
Up to 12 meters

The breech-lock mechanism enables bundle removal in hours instead of days. Critical for high-value production processes where every hour of downtime costs thousands of dollars in lost production.
Elimination of hot work during maintenance reduces fire and explosion risks. The positive locking mechanism prevents accidental opening during operation, ensuring operator safety.
Reduced maintenance labor, minimal specialized tooling requirements, and extended gasket service life result in significantly lower lifecycle costs compared to conventional flanged designs.
Uniform compression of gasket around entire circumference eliminates leak paths. The mechanical locking system maintains seal integrity even under thermal cycling and pressure transients.
Existing shell & tube exchangers can be retrofitted with breech-lock closure assemblies, providing upgrade path for aging equipment without complete replacement.
Quick bundle changeout enables rapid process modifications. Multiple bundle designs can be maintained for different operating conditions or product campaigns.
Ideal for high-fouling service where frequent cleaning is required:
