Aqueous Technologies Trident ZDO Automatic Defluxing System

“Zero discharge” means that the system operates without sending rinse or wash fluid out to drains or wastewater. The Trident ZDO filters, de-ionises, and recycles both the wash solution and the rinse water internally. This minimises environmental impact, helps avoid costly permits or drain management, and supports sustainability goals.

The Trident ZDO is capable of removing any flux from any alloy, including water-soluble (polar) and non-polar or non-water-soluble flux types. It’s designed for post-reflow circuit assemblies of mixed technologies.

It includes automatic wash, rinse, and dry cycles. The wash uses defluxing chemistry or DI water, sprays via precision fan-jet nozzles. The rinse uses filtered / recycled water, and drying is achieved through radiant and convection hot air to thoroughly remove moisture from assemblies.

It has built-in cleanliness verification technology so you can set desired cleanliness levels. It also includes SPC (Statistical Process Control) data collection with an SQL database, report generation, and advanced multi-query search capabilities. All process parameters (times, temperatures, chemical levels etc.) are logged.

• Dimensions: approximately 42.25″ Depth × 56″ Width × 70″ Height.
• Electrical supply: 208-240 VAC, 3-phase, 40 amps or 400 VAC 3-phase, 30 amps.
• Plumbing / construction: stainless-steel fluid delivery, welded steel frame, steel panels with durable finish.

The system has the option to include an automatic chemical dosing and mixing system (HydroBlend) that proportionally mixes wash solution. All wash and rinse fluids are recirculated / reused, with internal filtering / de-ionisation to maintain quality. This extends chemical life and reduces chemical waste and operating cost.

The ZDO uses an asymmetrical fan-jet spray system with stainless steel nozzles placed at 15° angles, plus an oscillating board rack. These features help reduce spray “shadowing” under components and ensure spray coverage even under tight areas.

• Although “zero discharge,” internal water recycling requires maintenance of filters, de-ionisation units, and chemical mix controls to maintain performance.
• The footprint and electrical needs are significant; facility must support the power draw and three-phase supply.
• Very large boards or fixtures may require optional upper racks or extra process chambers for throughput or spatial compatibility.
• Cycle time may be longer than simpler, less eco-friendly defluxing systems due to the additional rinse / recycle / drying steps. Ensuring good process design mitigates this. (Inferential based on process complexity.)
