Coating
Spray Coaters
Coating is a process in which the surfaces of particles are carefully coated and refined. It is more than just a protective layer; coating is used to purposefully modify surface properties to meet specific requirements.
This process is widely applied across various industries, including agrochemical, pharmaceutical, and many others, where diverse coating techniques are utilized to influence surface structure effectively.
Coating applications include protection against environmental factors, taste masking, and the controlled release of active substances, offering significant functional advantages in product performance.
The selection of the coating is based on:
- the targeted functionality of the coating layer
- the size and shape of the particles to be coated
- the efficiency of the process (in terms of material, time and personnel requirements)
Spray Coaters: Fluidized Bed
Granulating, Coating, and Pelletizing with Unique Glatt Nozzles.
The Glatt LD top spray nozzle is specifically designed for granulation and coating processes. Its intelligent, lightweight construction ensures optimal spray rates, prevents clogging, allows for easy handling, and offers excellent cleanability. In addition, the nozzle is extremely robust. Operating on the binary principle, it can be precisely adjusted for a wide range of granulation processes. The nozzle is also equipped with SmartID technology for smart verification of critical process components.
The patented Glatt HS method is applied for coating processes in Wurster (bottom spray) systems. The HS Wurster spray nozzle delivers very high spray rates and enables the efficient coating of even micro-fine particles as small as 50 μm.
In direct pelletizing, rotor coating, and high-performance (HP) spray systems, the nozzle sprays laterally and directly into the product bed. For powder layering, a specialized three-component nozzle is used to precisely meter both the powder and spraying liquid, ensuring accurate and uniform layering.
Drum Coaters
As the pioneer and developer of the first fully perforated drum coating system, Glatt now offers a comprehensive range of advanced drum coaters for the intelligent coating of tablets.
The portfolio includes systems designed for laboratory and pilot-scale applications, as well as coaters for large-scale pharmaceutical production. Laboratory systems are capable of coating very small quantities, starting from just a few grams, while production systems are engineered to handle batch sizes well in excess of one ton. Each solution is tailored to meet specific customer requirements.

This innovative coating solution has been engineered for exceptionally fast mixing and coating processes and is recognized as one of the fastest tablet coaters in the world. Its wetting area ranges from 5% to 100%, all achievable with a single drum.
The new coater from Glatt sets a new standard in performance and versatility. It ensures consistently high product quality, excellent reproducibility, extensive process safety, and user-friendly operation.
Revolutionary Upgrade of the GCSmart Drum Coater Series
The GCSmart drum coater series has been revolutionized to deliver outstanding speed, performance, and flexibility, all while ensuring maximum process reliability and excellent user handling.
Specifically developed for extremely fast coating processes, this advanced system guarantees consistently high product quality and reproducibility across all operations. The coater is designed to flexibly accommodate a wide range of drum filling levels, from as low as 5% to full capacity at 100%.
Lab and Pilot Systems
Small-scale production for clinical trials, the testing of optimal coatings for new tablets, or the evaluation of different coating processes can all be efficiently supported with our lab and pilot systems.
Our multi-functional lab and pilot systems for coating processes have been proven repeatedly in process development and have demonstrated reliable scalability from laboratory to full production. Their modular design and flexible configuration allow for quick and effective adaptation to changing process requirements.
This technically reliable pan coater is specifically designed to deliver optimal film coating results on a very small scale. It is equipped with three interchangeable drums, allowing for maximum flexibility and precision in laboratory applications.
The system offers high process efficiency, as the entire housing can be quickly dismantled and reassembled within seconds for drum changes or cleaning. This makes it an ideal laboratory unit for research and development activities.
The MultiLab process module is specifically designed for optimized tablet coating on a small scale. It features a flat spray nozzle that ensures homogeneous and adjustable spraying while consistently delivering reproducible quality.
The system is equipped with exchangeable coating pans in sizes of 2.5 liters, 5 liters, 9 liters, and 12 liters, providing a flexible working range from 1.3 liters to 12 liters.
The GMPC II is a highly flexible, multi-purpose machine designed for research and development at laboratory and pilot scales. It is suitable for coating tablets with aqueous or organic lacquer suspensions, as well as for pan-coating particles using sugar syrup.
The machine features a well-conceived, compact design that allows for quick installation and easy handling. Interchangeable drums enable the processing of batch sizes ranging from 1.5 to 45 kilograms, providing versatility for a wide range of applications.
GCSD Spray System
Perfect coating requires a homogeneous, adjustable spray pattern combined with constant and reproducible spraying behaviour. The GCSD spray system has been specifically developed to meet these exact requirements.
The GCSD nozzle is equipped with Glatt’s innovative ABC technology (Anti-Bearding-Cap), which enables spraying without bearding for the first time. This advanced feature prevents the clogging of liquid inlets and ensures continuous, even spraying without process interruptions or the need for frequent cleaning of the nozzle outlets.
The system allows for finely adjustable and reproducible droplet sizes, guaranteeing uniform liquid distribution throughout the spray jet. This solution offers perfectly controlled spray behaviour, delivering optimal results in every coating process.
