Tailor-made solutions for the chemical industry
We supply safe, efficient, sustainable, worldwide solutions for the chemical plants and manufacturing facilities.
We supply safe, efficient, sustainable, worldwide solutions for the chemical plants and manufacturing facilities.

In the chemical industry, process safety, compliance with standards and efficiency are crucial.
Ziemann Holvrieka supplies both standard solutions and custom-designed stainless steel tanks and systems that meet the highest safety standards and integrate seamlessly into your processes.
貯蔵タンク
Our storage tanks are designed for the safe handling of chemicals, solvents, and intermediate products. Up to a diameter of 7.5 meters, tanks can be fully manufactured as one-piece units in the factory; larger dimensions are realized through flexible on-site assembly.
Designs comply with international standards such as API, PED, ASME, and ASME BPE, with ATEX-compliant configurations available. The focus is on maximum safety, high corrosion resistance, and fully verified material quality and leak tightness.
Tailor-made tanks
Whether biogas, hydrogen, CO² or aggressive chemicals – we supply tailor-made special tanks from a wide selection of materials.
All of the solutions we deliver are designed to meet the relevant environmental and safety requirements and can be seamlessly integrated into complex process chains.
Pressure vessels
Our pressure vessels are capable of handling demanding high-pressure processes such as hydrocracking or gas storage. Certifications according to PED and ASME standards, as well as ATEX compliance for explosive media, are standard.
Our design and manufacturing aim for maximum strength and process reliability, supported by comprehensive testing and documentation packages.
Process tanks
Our process tanks are designed for mixing, reaction, and polymerization processes, ensuring reliable and controlled operation. They are equipped with agitators as well as integrated heating and cooling systems tailored to process requirements.
All tanks are designed to be pressure-resistant and comply with relevant safety standards. The focus is on stable processes and consistent product quality.
Silos
Our silos reliably store bulk materials such as catalysts, sulfur granules, or additives. Designed according to Eurocode 3, they meet ATEX requirements; a corrosion-resistant version is available.
Optionally integrated discharge systems and sensors improve flow behavior, level control and process monitoring.
Tank accessories
In addition to their various applications, our tanks also offer accessories that you can use to customize them to your individual needs:
Walkway systems for safe access, insulation for energy efficiency, agitators for homogeneous processes. Available in stainless/carbon steel as well as pre-configured skids. Spare parts and service ensure availability, reliable operation throughout the product lifecycle, and predictable costs.

Complete solutions including engineering, automation and assembly up to safe commissioning.
We integrate safety and explosion protection systems, agitators, skids, and steel structures (stainless/carbon steel). This reduces interfaces, risks, and project durations.

Our tanks and systems meet the relevant chemical industry standards – including complete documentation and testing. This ensures legal certainty, speeds up permitting processes, and increases plant safety.
