Solutions

Process tanks

We design and produce process tanks with variety of capabilities, including:

  • Heating, cooling, melting, reduction
  • Mixing, homogenizing, emulsifying, high shear mixing
  • Cooking, fermenting, carbonating
  • Vacuum, pressure
  • Measuring, weighing
  • Automation
  • Indoor, outdoor

Pressure equipment

Under our expertise in pressure vessels, we ensure:

  • The use of materials sourced from controlled and certified origins.
  • Implementation of qualified and verified fabrication procedures.
  • Conducting non-destructive testing.
  • Design according to established industry standards.

In the European market, the design, manufacture, and use of pressure equipment adhere to the PED (Pressure Equipment Directive) 2014/68/EU standard. As of April 2025, we will also hold ASME certification.

We manufacture custom vessels that perfectly meet your industrial requirements, including specific products, usage, environment, and operating conditions. Our tanks can be constructed from materials such as stainless steel, duplex, nickel alloys, Incoloy, and Hastelloy.

Mixing solutions

Mixing, blending, emulsifying and agitation of various substances.

We specialize in designing stainless steel tanks that serve a wide range of mixing needs, including liquids, powder-to-liquid, solids, and agitation to prevent sedimentation.

Even if you are unsure about which design to choose, we are here to expertly guide you through the process. We ensure optimal and efficient mixing results.

Lab scale & pilot equipment

We design and engineer pilot units and lab-scale test production units for the food and cosmetics industry, providing both customized solutions for your needs and ready-made options.

Pilot units with various functions allow you to conduct R&D, develop recipes, and test products for food and other innovations, and simulate large production lines.

Automation

With our expertise in process automation, we can design and implement tailored automation systems.

Our solutions range from programmable logic controllers (PLCs) to supervisory control and data acquisition (SCADA) systems, ensuring seamless integration and intelligent monitoring of operations, while also addressing simpler needs with basic process controllers.

Our engineers are ready to assess your specific requirements and work out the suitable automation solutions to meet your needs.

On site built tanks

At Thorsteel we have expertise in building customized large stainless steel storage tanks, all to be assembled on-location. Our specialized skilled team performs on-site manufacturing, with all engineering managed entirely by Thorsteel, ensuring oversight at every stage of the process.

We offer customized tanks with capacity of up to 10,000 m³, constructed and welded at your location.

Other equipment

We design and manufacture custom solutions for skids, container setups and mobile process units to comply client’s specific requirements. Our mobile process tanks with automatic heating and adjustable speed agitator help to reduce manufacturing waste and quickly increase production capacity.

We find solutions to set up equipment in confined and challenging access spaces.

Thorsteel has competence to design and build large infrastructure units in cooperation with world-wide corporations.

We excel in pharma-grade surface finishing.
