Robotics

Remote and automated cleaning systems that take people out of confined spaces and hazardous environments — cleaning online, underwater and on vertical surfaces without taking the asset out of service.

Preventative Maintenance

Data-driven maintenance strategies that improve plant reliability, increase production output, and reduce unplanned downtime.

What We Do

Online Tube Cleaning Systems

Positioning: Zero-downtime differentiator — cleans while the plant runs
Fully automatic tube cleaning of condensers, chillers, and heat exchangers while the plant remains in operation — no shutdown, no production loss. SJA represents Innovas Technologies, supplying and supporting the award-winning Helios Tube Cleaning System®, which circulates sponge balls through heat exchanger tubes at programmed intervals to prevent residue, deposits, and bio-film from ever establishing. With operational reliability above 99.97% across millions of cleaning cycles worldwide and zero cooling process interruption, the Helios TCS converts cleaning from a shutdown cost into a continuous efficiency gain — the strongest possible expression of SJA's preventative maintenance philosophy.
Proven internationally across power generation, oil & gas refining, district cooling, and industrial plants — including a retrofit at New York's Empire State Building that cut energy consumption by 1.2 million kWh annually.
Directly relevant to: Eskom (condenser efficiency directly affects generation output), Sasol (process cooling and heat recovery), Sappi (evaporators and process exchangers)

Magnetic Crawler Robot

Positioning: Safety-critical differentiator — eliminates rope access & scaffolding
Remote-operated magnetic crawler robots that adhere to ferrous surfaces — tank shells, vessel walls, structural steel — to perform high-pressure cleaning, surface preparation, and coating removal at height or in hazardous areas. Eliminates the need for scaffolding, rope access, and personnel exposure to working-at-height and confined space risks, while delivering consistent, repeatable cleaning quality.
Directly relevant to: Sasol storage tank farms, Eskom structural and tank maintenance, all clients with bulk storage infrastructure and stringent HSE requirements

Underwater Vacuum Robot

Positioning: No-drain cleaning — major water and downtime savings
Submersible robotic vacuum systems that remove sludge, sediment, and debris from water-filled assets — cooling towers, dams, clarifiers, reservoirs, and process water ponds — without draining the asset or interrupting operations. Eliminates confined space entry, avoids the cost and water loss of draining and refilling, and keeps critical water infrastructure in service throughout cleaning.
Directly relevant to: Eskom cooling water dams and towers, Sasol process water infrastructure, Exxaro water management facilities, mine water impoundments across the corridor

Safety First

Fewer people in harm’s way

Remote systems keep technicians out of confined spaces and hazardous environments, and allow cleaning to continue while the asset stays in service.
