High Pressure reactors and process plants

Together with our partners, we design and manufacture high-pressure reactors for industrial production. The following reactor technologies are used:

 

• – Batch reactors
• – Semi-batch reactors (gas and/or liquid inlet)
• – Continuous flow reactors (continuous in one or more reagents)
• – Internal-receycle reactors (implementation of kneading studies in the gas, liquid or slurry phase).
• – Rotary basket reactors (for kinetic use and/or aging studies).

Our high-pressure reactors are characterised by the high quality of workmanship of all components used as well as by their high ease of operation. They have a modular design and are available in stainless steel or special steels in volumes from 60 ml to 100 litres. We offer solutions from 6 bar – 700 bar at a maximum of 350°C.

Examples of our high pressure reactors:

– series twister

• – series pinto
