Reactor Internals for Flow and Separation
We supply internals for fluid distribution, gas-liquid contact, bed support, and mist removal across a wide range of reactor configurations.

Stable Flow, Longer Runs
Axial / Downflow Reactor
Internals
Ekaislot supplies axial / downflow reactor internals for hydrotreating, hydrocracking, styrene monomer, esterification and PTA hydrogenation units, engineered to meet the mechanical and hydraulic requirements of licensed processes. Our axial flow reactor internals are designed to support stable flow distribution, catalyst utilization and run length in demanding fixed‑bed reactors.

High Open Area, Low ΔP
Radial Flow Reactor Internals
Radial flow reactor internals from Ekaislot are used in CCR reforming, aromatics units, ammonia converters and hydrodesulfurization reactors, where high open‑area and robust structures are critical to maintaining uniform radial flow and low pressure drop. Our radial flow reactor internals combine wedge wire technology with proven support structures to perform reliably under high pressure, high temperature and cyclic conditions.

Beyond Standard Designs
Special & Proprietary Reactor Internals
Beyond standard axial and radial reactors, Ekaislot co‑develops special and proprietary reactor internals for PTA, polysilicon, new energy and new materials applications, often under high‑temperature, high‑pressure and highly corrosive conditions. Many of these projects are import replacement programs driven by licensors and end users.
