Unicell® | CTI - Corrosion Technology International

The UNICELL®-Difference

The drain opening can be designed to accept
any suitable plug to ensure leak-free service.
Alternatively, the underside flange can be
accommodate a drain valve if required.

Drain opening

Part of STEULER-CTI's patented inlet system, the inlet opening
provides a smooth passage for electrolyte into the
cell beneath the electrode assembly.

Inlet Channel Opening

Controlled feed and fast feed systems provide
operating flexibility and improoved electrolyte
flow into the cell.

Inlet Bowl

End corbels and end cell side wall corbels
can be positioned to accommodate walkways or
pipe support gantrys and remove the need for
additional support structures around cell installation.

Support Corbels

Because the unicell is cast upside down, a sloping
floor can easily be incorporated to ensure easy
trouble-free cleaning. Slopes from 5 to 200 mm
over the cell lenght are common.

Sloped Floor

Overflow Bowl

STEULER-CTI's patented overflow system range from the
very simple to the complex and are designed to
take maximum advantage of the integral overflow
concept.

A direct flange connection enables leak proof
mounting of overflow pipework to the cell.
Alternatively, a pipe stub can be integrated into the
cell to accept a flexible hose connection.

Overflow Connection

To enable electrolyte decanting, a separate high
level outlet can be integrally cast into the cell,
either as a stand alone 'structure' or integrated
with the overflow pipe system.

Decant Outlet

316 stainless steel inserts can be integrated into
the structure at appropriate points to enable fixing
of pipe hangers, valve supports, busbar supports
and bolt-on corbel supports reducing the need
for separate support structures.

Corrosion Resistant Advanced Composite

Our advanced technology vinylester-based composite is specifically designed to provide superior chemical resistance and mechanical durability, withstanding the extreme environment of a refinery tank house.

Monolithic Construction

The UNICELL^® is the originally monolithically cast electrolytic cell with integrated overflow/decant and inlet piping systems. Eliminating cold joints and seams from cell designs has reduced long-term maintenance costs.

Non-Conductive FRP Rebar Reinforcement

Fiberglass Reinforced Plastic Rebar provides structural protection against catastrophic failure to each UNICELL^® without the possibility of creating short circuits.

Easy Installation

Pre-cast piping connections ensure an effortless field hook-up, save expensive labour and materials, eliminate unnecessary downtime, and thereby improve overall productivity.

Advanced Wall Construction

STEULER-CTI’s advanced composite technology allows UNICELL^® wall designs that support electrodes and electrolyte with minimal deflection. Sleek wall design allows a tank house to add additional cells of electrodes to increase production capacity.

UNICELL^® ADVANCED DESIGN OPTIONS

Patented Integrally Cast Piping Systems

STEULER-CTI offers a variety of proven integrally cast piping systems. Pre-cast piping that is protected by STEULER-CTI’s advanced technical composite decreases initial installation expenses, costly production downtime and long-term maintenance costs.

Customised Inlet Designs

STEULER-CTI has inlet options for a variety of electrolyte flow patterns and fast filling capabilities. These precisely planned features provide better electrolyte flow control.

Overflow and Decant Designs

All UNICELLs^® contain a proven integrated cast overflow arrangement. Overflow designs are available that can allow decantation at a controlled level without disturbing slimes to aid in maintaining clarity of the electrolyte, reducing unnecessary slimes treatment.

Sloped UNICELL^® Bottom Designs

The slope of the UNICELL^® floor is dependent on the needs of each individual tankhouse. STEULER-CTI has numerous options that can increase tankhouse productivity and slimes recovery.
