We are a leading manufacturer of thermoplastic storage tanks

Over 50 Years of Experience and Know-How

Our storage tanks are manufactured according to the German DIBt Construction Certification as well as according to the specification of the German Water Conservation Act (link media list). On request we also manufacture our tanks according to the European standard EN 12 573. The storage tanks are offered as double-walled tanks or flat-bottom tanks with containment (Equipment double-walled tanks / storage tanks with containment).

Furthermore, formoplast produces working tanks such as agitation tanks and conical tanks made of PE-HD or PP. All tanks are manufactured to your individual specifications. Our plastic tanks are used in many different branches of industry, including dairies, the foodstuffs industry and the pharmaceutical industry.

The tanks are suitable for HBV systems (for manufacturing, treatment and use) as well as LAU systems (for storage, filling and handling). For winter services or industry we offer brine plants for the production, storage and filling of brine or 20-23% NaCl solution.

Our services include the planning, design and manufacture of storage tanks

We are an approved specialist company for the installation, erection and repararation of plants for the storage, filling and handling of water-polluting substances. All plastic tanks are developed and manufactured in Germany. In comparison with panelled tanks, our winding technology offers the advantage of a stress-free cylinder manufacture for the optimum storage of your chemicals. All plastic tanks in our product range are manufactured with the greatest of care, are durable and comply with all relevant legal regulations.

Thanks to our many years of experience we can offer you optimum advice for the planning and implementation of your plants. We will be glad to inform you about our range of services and furnish you with a quotation for storage tanks and other products for your application needs.
