QC-System Introduction


Hazards of conventional container emptying.

The consequences when handling chemicals using conventional drum pumps, self-made suction lances or even just with tubes put into the container can be serious: hazardous substances continuously outgassing, drips when inserting and removing and the ever-present risk of contact with the chemical that is always associated with injury to operators, damage to production equipment, and sometimes even leading to building damage. Even totes with integrated ball valves do not stay non-drip for ever – no wonder because even a high-grade industrial valve costs more today than a standard tote with pre-mounted valve....

Safe, clean and flexible – it's that simple.

The clever, complete system

Over the decades, the QC-System from AS has developed into one of the world's leading dispensing systems for liquid chemicals. Not without reason. QC is more than just a simple fast-connect system; it is a precision tool manufactured from high-purity plastics for a versatile range of applications. Suitable for acids, alkalis and solvents – even aggressive and highly flammable products. Entirely free of metal and therefore immune to corrosion. The AS QC-System is primarily a sophisticated, highly flexible adapter system for simultaneous dispensing and ventilation in a closed circuit, which protects and takes care of handlers and the environment alike. It can be integrated into the supply chain perfectly. A clever, complete modular system with over 100,000 variants for small operations and large companies.

Always safe and clean chemical dispensing from drums, totes and canisters.

Fast connection: Thanks to the coding system that prevents product mix-ups

Click into place, screw tight, job done. The patented pin-hole coding system with clear medium assignment reliably prevents
product mix-ups.

Emission-free dispensing: Thanks to integrated ventilation

No uncontrolled escape of gases: Dispensing in closed circuits with safe ventilation via check valves, particle filters or spiral tubing. Practical: The second drum opening can remain sealed.

shut-off valves in the dispense heads shut-off valves in the dispense heads

Spill-free disconnection: Thanks to integrated check valves

No more spillage when disconnecting: The various shut-off valves in the dispense heads (e.g automatic check valves) remain tightly and reliably sealed.

Customer Experiences

A. L.

Engineering / Industrialisation

schülke is a wholly-owned subsidiary of the Air Liquide Group and one of the global market leaders for infection prevention. With more than 1000 employees and at 22 international branches, the company mainly develops and produces disinfectants, antiseptics, preservatives, biocides, medical skin care products, deodorant agents and system cleaners.

"The QC-System is the best and most comprehensive solution on the market - handling, variants, safety, support, everything fits. We see particular strengths of QC in the hygiene area and with hazardous substances. In the explosion-risk zones, dispensing is much easier and safer and the acceptance of the operators is without exception very good.

Above all, we were positively surprised that AS took time from the first moment to find the best solution. Especially in interaction with raw material suppliers, AS is very well networked, and this three-way relationship worked perfectly for us.”

Thomas Plötzke

Production / Dispatch Manager - Electronic Wet Chemicals

"As a manufacturer of high-purity hydrogen peroxide for the semiconductor industry, it is crucial for us that our products are filled safely and cleanly.

Through many years of cooperation with AS, we have achieved this goal. Their closed-loop QC® filling system and the use of SupplyLine® enable us to fill without mix-ups and with 100% traceability. This has allowed us not only to improve the quality of our products, but also to offer our customers real added value.

We are very satisfied with the cooperation with AS and are happy to recommend their products and services to others."

Pia Thörnblom

Materials and Process Engineer

"GKN Aerospace Sweden develops and manufactures advanced engine parts for aircraft as well as spacecraft. We also do engine maintenance and overhaul. Some parts go through our etching and pickling plant in which we use a process solution that consist of a combination of Nitric acid and Hydrofluoric acid.

Since safety, health and environment are key issues to our business we have been looking for a safe way to add Hydrofluoric acid into our process tanks. Our chemical supplier recommended us to get in contact with AS Strömungstechnik, and that's how we found out about the QC-System. We have used the system for about a year and it works beyond expectation. The system performs really well so we have plans to expand its use further to other processes and chemicals."

David Driesen

eSDS Product Regulation / Chemical Preparations & Application

"Agfa-Gevaert produces in their site in Heultje fine chemicals which are used especially for the manufacture of films. To produce those chemicals many liquid ingredients are needed.
Because of the new regulations imposed by the European Chemical Agency ECHA concerning Strictly Controlled Conditions, transport of intermediates into a reactor had to be executed in a closed-loop system. Therefore, Agfa had to look for a system to follow those new legislation.

Concerning the use of intermediates in a liquid state, Agfa now uses the QC-System of AS Strömungstechnik to empty all kind of drums (plastic, metal, composite) in different volumes.

AS is a recommended company because they can produce in function of the demand of the customer followed by an excellent service afterwards. They made us very happy with their way of working and we wish them therefore many clients in the future."

Robert Andersen

Project Engineer / Lean Leader

"BLÜCHER Metal A/S produces Drainage Systems in Stainless Steel sold under the brand name “BLÜCHER”. All our products go through our Pickling Plant where we use mixed acids containing HNO3 and HF. We have a high focus on Safety and Environment therefore we have been looking for a more safe system for pumping the Pickling Acids from IBC to the bathes, especially when changing from one empty IBC to a new one. For continuous dozing we need to pump to three different bathes at the same time, but not necessarily in the same amounts.

After some search and help from our acid supplier we found the QC-System from AS Strömungstechnik. AS solved the problem for us. As a supplement we also have bought and implemented a QC-System for high speed dozing for use when we set a new pickling bath. We have been using the system for some months now and the operators are very pleased with it. They feel safer which was the goal of the project from start."

Robin Ehlers

Team leader Production / Fermentation

E-nema is a globally active company which produces insect-pathogenic roundworms and a range of additional biological plant protection agents based on microorganisms.

"With the QC-System we were able to reduce the odor nuisance of several pH corrective products for our fermentation processes to a minimum. Since we place great value on the protection of people, the environment and our production facilities, the drip-free QC-System dispense heads are perfectly suited for our purposes. Because of the possibility to customize hose connections, the QC-System can be used in many applications around our facility."

Solar and microchip

Semiconductor / Solar

The clever, complete system for the semiconductor and solar industry. For better protection and more efficient processes.

The main focus of the production of semiconductors and solar cells was also the basic premise of AS when developing the QC-System: absolute protection of handlers and the environment from chemicals and, at the same time, the protection of high-purity chemicals from contamination. Due to our high purity plastics and our high standards towards cleanness, our products meet the critical requirements towards purity of the semiconductor industry.

Pharmaceuticals and Foodstuffs

Pharmaceuticals / Foodstuffs

Ultrapure plastics enable a cleaner supply of chemicals and the flexible connection options can be seamlessly integrated into existing systems. Specially developed versions made from stainless steel also enable the compliant handling of solvents in the pharmaceutical and food industries.



The handling of corrosive and aggressive chemicals is a critical part of many production steps in chemical process industries, be it surface treatment of metals, etching of glas or manufacturing of adhesives. Therefore, it is necessary to ensure the full protection of operators and the environment from these chemicals – from the first process step onwards.
