01 / What We Do
Direct Replacement — US & EU
Drop-in replacements for both American and European standard systems. Send us your OEM model number and we match the vessel dimension for dimension — Pfaudler®, De Dietrich®, Thaletec® — same nozzle layout, same footprint, faster delivery.
Custom Engineering
From non-standard nozzle configurations to exotic alloy shells, our engineering team designs equipment to your exact process specifications.
Global Standards Compliance
All equipment manufactured to ASME (North America), PED (EU/UK), and JIS (Japan) standards with full documentation and material traceability.
Inside the Vessel
Engineered from the glass out.
Every layer of a glass-lined reactor exists for a reason. Here’s what you’re specifying when you specify ours.
- 01Borosilicate glass lining
Fused to the steel shell at high temperature — pore-free, chemically inert, and 100% spark tested at 20,000V.
- 02Precision agitation
Glass-lined impellers and shafts matched to your mixing duty, from anchor to retreat-blade styles.
- 03Jacketed heat transfer
Conventional and half-pipe jackets rated from −196°C to 200°C for tight reaction control.
- 04All-welded nozzles
No threaded connections on wetted surfaces — every penetration is welded, lined, and tested.
02 / Equipment Portfolio
Every vessel ships pore-free, HVT spark-tested, and fully documented.
