Roller Compaction Technology Increasingly Important For Production Of Granules

Roller compaction is becoming an increasingly important agglomeration technology for the production of granules, as the pharmaceutical industry looks at ways in which it can introduce lean manufacturing to reduce its R&D and manufacturing costs.

GERTEIS® is a Swiss manufacturer of advanced high-quality roller compactors. GERTEIS® has set the standard with its unique dry granulation technology. The company’s understanding of the dry granulation process combined with patented roller compaction systems make GERTEIS® the technology leader in the field of dry granulation.

GERTEIS® has a depth of dry granulation knowledge and experience; its team of roller compaction specialists can evaluate an application and quickly predict and establish the best roller compaction parameters to achieve the optimum dry granulation process.

Gerteis Maschinen + Processengineering AG is the optimal solution for your dry granulation needs. From R&D trials to continuous manufacturing, Gerteis roller compactors can process powders, even those with extremely poor flow properties, far better than any other machine on the market, without the need for vacuum deaeration or roller cooling.

The Pactor line, which can be upgraded with High Containment as well as CIP for potent compounds, represent the best machines to launch a QbD program. Linear scale-up from R&D to high volume production has never been easier due to Gerteis’ sophisticated roller design.

In addition to any required Technical support, Gerteis is pleased to provide Formulation support to all of its customers.

Our product portfolio includes machines capable of product output ranging from 10g per trial up to 400kg / h.

Roller Compaction: Process Analytical Tools

The GERTEIS® roller compactors are able to control and measure all product quality relevant parameters (e.g. force, gap and roll speed) on-line in order to fulfill the requirements of the pharmaceutical industry for a well controlled and documented manufacturing process.

The GERTEIS® roller compactors are able to control and measure all product quality relevant parameters (e.g. force, gap and roll speed) on-line in order to fulfill the requirements of the pharmaceutical industry for a well controlled and documented manufacturing process. All the parameters are calibrated and validated. Additionally, in order to cope with batch to batch variations, our machines are fitted with control systems to allow equal granule properties during manufacturing according to PAT.

GERTEIS MASCHINEN + PROCESSENGINEERING AG had its beginnings as a one-man enterprise in Jona, Switzerland where the corporate headquarters is located to this day. Throughout the years the company grew exponentially and established itself as the market leader for premium dry granulation equipment. With our focus on roller compactors, we pride ourselves in possessing an in-depth knowledge on all aspects of dry granulation and the related processes which is much to the benefit of our customers.


Customer Success Story

Nucleo Life Sciences is a modern and state-of-the-art contract development & research lab (CRO) based in San Rafael, CA covering all phases of small molecule drug product development.
The founders have a long history of using the Gerteis line of pharmaceutical roller compactors for developing and
scaling up high volume pharmaceutical products at various manufacturing plants all over the world.
Pharmaceutical roller compaction is an efficient dry granulation process used to make increase the particle size of poorly flowing powders by compacting into a ribbon or compact. This compacted blend is then milled to increase the
particle size and producing blend that is free flowing and suitable for tablet compression, capsule filling, or filling
into sachets. Gerteis is a Swiss manufacturer of advanced high-quality roller compactor and has set the global
standard with their unique design of dry granulation technology.
“When we moved our lab from San Francisco to San Rafael the Gerteis Mini-Pactor was the first piece of equipment installed in the pilot plant,”recalls Mark Menning, PhD, CEO of
Nucleo Life Sciences. “Having the proper equipment in our facility allows us to perform our prototyping then produce GMP supplies using the same equipment. If the product scales up to a larger batch size or a commercial
facility, we can simply take the recipes in house then transfer it directly to the contract manufacturer (CMO).”
“When selecting equipment vendors, customer support is a critical part of the relationship,” said Lara Park Menning,
COO of Nucleo Life Sciences. “We prioritize client support in our company so we expect the same level of support
and passion from our equipment partners. Gerteis has always exceeded with their technical expertise and
support. Their machines are indestructible with high performance output.”
Pharmaceutical roller compaction is becoming an increasingly important agglomeration technology for the
production of granules, as the pharmaceutical industry looks at ways in which it can introduce lean manufacturing to reduce its R&D and manufacturing costs by QbD.

ULTRA-PACTOR® High Containment Roller Compactor

The ULTRA-PACTOR® High Containment Roller Compactor is the most technologically advanced roller compactor for optimal protection from highly active and hazardous substances.

High Containment Roller Compactor

The ULTRA-PACTOR® High Containment Roller Compactor is designed for full Cleaning-In-Place, so that operator contact with hazardous products is completely avoided. The ULTRA-PACTOR® roller compactor guarantees optimal protection for the operator against highly active and hazardous substances. With its ATEX-compliancy and the ability to purge N2 into the process area, this roller compactor truly pushes the boundaries in containment installations for dry granulation applications.

ULTRA-PRACTOR® is the most technologically advanced roller compactor that Gerteis® has produced. Building upon the well proven MACRO-PACTOR® - and with output capacities up to 400kg per hour - the ULTRA-PACTOR® is designed within an ergonomic containment isolator to allow processing of very potent products where high containment is required. In accordance with high containment good practice, the ULTRA-PACTOR® roller compactor is
