Inlet Bowl

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

Inlet Channel 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.

Decant Outlet

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.

Drain Opening

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

Sloped Floor

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.

Equipment Hanger Inserts

Stainless steel (eg. 316) 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.

Support Corbels

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.

Overflow Connection

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 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.

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.


INSTALLATION

STEULER-CTI not only manufactures and supplies UNICELLs®. We can install them as well, whether on Greenfield sites, or replacing old cells in existing refineries. Our expertise covers the entire project requirement:

  • Detailed project planning including development of work plans, safety plans, work schedules and the like, from power down to power up
  • Dismantling of existing cell assemblies including removal of liners, pipework and all other connected equipment
  • Rehabilitation of existing support structures
  • Installation of UNICELLS® including placement and leveling 
  • Supply and connection of piping systems, pipe hangers, etc ...
  • Re-fitting walkways
  • Testing and re-commissioning of cell arrangement
