Product applications

production plant for liquid

In a new and fully automated plant various liquid pharmaceutical products are produced and stored. Each of the three production tanks with a content of 500, 1000 and 2000 litres respectively can be connected with each of the 5 storage tanks ( 2 x 1000, 3 x 2000 l) by means of a change over system. Up to three different production steps are possible. As the products are also exported to the USA, the plant is designed to cGMP and approved by FDA. Planning and construction of the plant are based on the latest directives and standards.
