Waterjet cutting with ConSus® combines productivity and cutting quality

Waterjet cutting is becoming more and more important comparing to other cutting techniques. The Water Abrasive Injection System (WAIS) currently common in the industry, however, is increasingly reaching its limits. Contrary to this, the Water Abrasive Suspension (WAS) system enables three times higher performance and better quality at significantly lower pressures.

ConSus enables permanent water jet cutting in the suspension process – innovative and globally patented. Especially with increased cutting depths and the processing of high-strength materials, there are technological and economic advantages compared to the conventional water abrasive injection system.

  • Only 1500 bar
  • up to 3 times faster
  • 70 % energy savings
  • 70 % less noise
  • 50 % less particle emissions
  • 50 % CO2 savings
  • 50 % cost savings

Convincing Results

With ConSus you achieve excellent cutting quality in a wide variety of materials and in challenging tasks.

Our sample cuts speak for themselves:

Functionality of the Suspension Jet and ConSus

At less than half the pressure, the ANT suspension jet cuts twice to three times faster than conventional waterjet cutting methods. Since the abrasive particles in WAS systems are bound directly in the water without air, the suspension jet is much more stable, precise and powerful than the injection jet.

The abrasive mixing unit ConSus enables the continuous supply of the abrasive and an uninterrupted cutting process via a worldwide patented sluice system.

System Solution

ConSus as upgrade for your existing equipment or a new complete system

A WAS cutting system consists of ConSus, a cutting device and a pump. Optionally, an abrasive recycling unit (ARU) and a water treatment system can be integrated.

ConSus Calc a Cut makes it easy to compare cutting performance, costs and yield.

As a progressive web app, the comparison calculator can be used in a browser or as installed app on an Android or iOS smartphone.

ConSus vs. Injection: The Cutting Race

The ConSus performance factor shown in a direct competition:

More powerful, lower-emission and more cost-effective cutting

A study by the Fraunhofer IPT on the emission, cost and performance comparison "ConSus 1500" with the injector process shows the decisive advantages of the water abrasive suspension process with ConSus:

  • Reduced noise and particle emissions during waterjet cutting thanks to the two-phase suspension jet of water and abrasive without air.
  • WAS systems show a considerably higher removal rate, which outweighs the initially higher operation costs (per h) by far
  • Especially with increased cutting depths and the processing of high-strength materials, there are technological and economic advantages.
  • Protection of abrasive ensures more economical cutting and high recyclability of 80 % and more

More information on productivity, cut quality and sustainability of ConSus and details on the results of the investigation of the Fraunhofer IPT can be found in our whitepaper.

Sustainability and Climate Protection

For a 1000 mm long cut (Q3) through a 20 mm thick mild steel plate (S235JR), ConSus can reduce CO2 emissions by over 50% compared to the conventional water abrasive injection (WAIS) process.

The calculation includes emissions from the production of the required cutting materials and the power consumption of the machine. For the production of the required cutting materials, only the emissions related to the extraction and processing of raw materials are considered, but not the origin of the raw materials.

ARU, the Abrasive Recycling Unit

Sustainable production and efficiency are not mutually exclusive. The centralised or decentralised processing of 80 % and more of the abrasive with the Abrasive Recycling Unit ARU developed by ANT significantly reduces consumption costs.
