Industrial perspective for the
Narrowspan atomiser
Narrowspan achieves powders with uniform-sized particles, creating a largely dust free, easily wettable product with a high flowability, from a rotary atomiser wheel
Until now, powders with uniform-sized particles were achievable only in large nozzle towers Narrowspan, however, achieves this uniformity, creating a largely dust free, easily wettable product with a high flowability, from a rotary atomiser wheel

NEW aseptic filling technology
GEA Procomac, specialists in aseptic filling technology for PET containers, has received a letter of non-objection (LNO) from the US FDA, for aseptic filling systems for low acid shelf-stable products
Reduced costs for pharmaceutical process lines
The new BuckValve MC is a new concept in high containment valves that makes the transfer of active ingredients or chemicals between IBCs (Intermediate Bulk Containers) much easer and less expensive
This reduces costs and allows the use of smaller buildings to house the plant equipment.
The Narrowspan is suitable for new-build projects, or for retrofit to improve the efficiency of existing production plants.
The Narrowspan produces a low-dust product, which is important for explosion safety, personal health, and the environment.
The uniform particle size distribution means a controlled functionality of the final product.
A high bulk density can be achieved together with a free flowing product with large particle size.
The product does not break into fines, compared with agglomerates that are generally more brittle.
Narrowspan products are easier to disperse and wet in their respective solvents.
Large, uniform, free flowing particles allow easy handling and packing.
Variation in particle size from fine to coarse is possible while running the plant by controlling the rotation speed of the atomiser wheel.
Large particles can be produced in smaller diameter chambers.
Rebuilding of existing plants allows for the manufacture of added value products, with low building height and hence investment costs, compared to nozzle towers.
These features are all proven in tests and have been working in industrial applications for the last decade.
