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.
Liquid Distributor Tray
We design and fabricate reactor and column internals, including liquid and vapor distributors, collectors, support grids, trays, demister pads, and packing supports. Each assembly is tailored to your media, temperature, pressure, corrosion profile, and plot space limits with documented materials and qualified weld procedures for full traceability.

Performance
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.
