Our background is the manufacture of chemical facilities and we take pride in our quality standards of all Henze products. Our wide range of special constructions represents our goal to also provide solutions for extraordinary requirements.
We offer you:
- Storage tanks with catcher installations – one walled
- Standing and laying storage tanks – double walled
- Process, mixture and working tanks
- Ventilation pipelines, gas scrubbers, exhaust stacks
- Special constructions and molded parts of all types
Henze-storage tanks serve as environment safe storage of acids and lyes such as acetic acid, hydrofluoric acid, sodium hypochlorite, nitric acid, hydrochloric acid, sulfuric acid, Chlorine water or other water polluting chemical substances according to § 19 WHG.
Helically extruded Pipes for containers are designed and statically calculated according to DVS 2205 Page 1 to 4, as well as EN 12573, 1-4. The mentioned guidelines constitute the foundation for the design of containers and apparatus.
DVS provides the processor of semi-finished products from thermoplastic plastics guidelines for creating a calculation basis for ventilation systems and apparatus construction. The calculation of the building elements are based on long term statistic data. There are in general three criteria to consider:
1. Tensions or stretching
2. Deformation (ie by bending)
3. Stability (ie buckling or dents)
The permissible tension is assessed based upon the creep rupture strength, the reduction factor, the joining factor and the safety factor.

Acid resistant plastic containers
Plastic tank construction and the manufacture of acid-resistant plastic tanks have long been among our core competencies. To make our containers resistant to various aggressive liquids such as acids, alkalis, gases or waste water, we use only high-quality engineering plastics for the production of plastic containers:
- Polyethylene (PE)
- High density polyethylene (PE-HD or HDPE)
- Polypropylene (PP)
- Polyvinylidene fluoride (PVDF)
We thus ensure environmentally safe storage of alkalis and acids in our plastic containers. Acids include, for example, acetic acid, sodium hypochlorite, hydrofluoric acid, nitric acid, hydrochloric acid, chlorinated water, sulfuric acid or other chemical substances hazardous to water according to § 19 i WHG.
The WiRoTec Henze plastic tank construction range includes:
- PE container
- PE storage tanks (upright and horizontal)
- Process vessel
- Production, agitator and working vessels
- Flat-bottom tank
- Round container
- Rectangular tank
Special plastic container
In addition to common plastic tanks such as PE tanks, storage tanks, process tanks, flat-bottom tanks, production tanks, working tanks or agitator tanks, we also manufacture special components from the field of plastic tank construction for you. Please let us know your requirements or ideas and we will take care of the planning and implementation: +49 (0) 22 4 1- 98 19 0.
