In the hameln pharma sterile production plant differentiation is generally made between four cleanroom classes in which various particle concentrations are permitted and consequently different regulations are enforced regarding clothing and behaviour. The pass-through system that links all the different cleanroom classes together is designed so that when passing from one zone to the next standardised processes are implemented. In addition, the necessity of passing in and out through air lock doors has been minimised. As a result efficiency is increased and the risk of contamination is reduced.
Efficiency by designStandardisation and reduction to the minimum requirements - the silver bullet to a slender production. This principle has also been realised consequently when arranging the filling lines. setting up the machines in the form of a "U” reduces the space needed for the highest cleanroom class and increases the employees´ productivity. Both bringing in the glass containers and removing the filled and sealed ampoules and vials can be carried out in a class D cleanroom by one and the same employee who consequently does not have to move between cleanrooms of different classes. Another employee in the adjacent class B cleanroom is responsible for fully monitoring the filling process. Less action in the cleanroom means a reduced risk of contamination – while at the same time increasing productivity.
