Coating system
TULZ®
TULZ® –
Immersion-recirculation-painting centrifuge
The TULZ® coating system is used in the electroplating sector in particular. One of the main areas of application is zinc flake coating. Panning and circulating are just as important as a high material throughput. We have been creating coating systems for surface treatment for 50 years.
The TULZ® is optimized for the future
The TULZ® is an essential element in an automatic coating system. It has been continuously developed over the years and optimized for the future. With this system, it is now also possible to coat rack goods as well as drum goods.
The TULZ® is also ideal for applying various sealants, e.g. in the electroplating sector. However, the main area of application is the application of zinc flake systems. Thanks to the movable paint container with quick-release couplings, media can be changed within a very short time and in just a few steps, without reducing the material throughput. Another advantage is the ability to swivel the centrifuge basket up to 90° in order to circulate the parts.
The TULZ® Color Recovery System (PRS)
As the centrifuge basket is completely closed in the station, there is no reduction in the usable volume. A swivel angle greater than 75° is particularly important for flat punched parts and panes to ensure optimum coating quality. The TULZ® coating station is equipped with the newly developed, patented “Paint Recovery System (PRS)”. Here, the paint carriages are designed with a cylindrical spin-off jacket. The spin-off and recirculation cycles are then carried out in the spin-off jacket clamped around the centrifuge drum.
Significant paint savings
The advantage of this system is a considerable saving in paint, as on the one hand there is no swirling of the paint in the interior of the coating station and on the other hand the centrifuged medium in the centrifuge jacket detaches itself from the wall again when immersed at the end of the cycle. Thanks to the variable, freely parameterizable treatment program, even small screws with internal attack can be coated to a very high quality. An economical loading quantity can be achieved in the basket.

The right coating system
The station is completely encapsulated and equipped with a ventilation system. This makes the system ideal for processing solvent-based coating systems. Another advantage is the “loose” coating basket, i.e. when the coating medium is changed, the coating basket can be easily replaced or removed for cleaning. In automatic systems, the basket is changed fully automatically without reducing the throughput of the system. The centrifuge is available in different sizes. In the TULZ® 900 (basket diameter 900 mm), for example, loading weights of up to 250 kg can be coated, with cycle times of less than 2 minutes.

Immersion circulating paint centrifuge in use
For laboratory applications
A smaller version, the 300/500 models, was developed especially for laboratory applications and sample coatings. With this machine, sample coatings can be applied directly in the paint manufacturer’s delivery container (hobbock). For series production, the station can also be operated with a larger coating basket (Ø 500 mm) and a paint container. The coating system can be fully integrated into the WMV modular system, i.e. existing systems can also be easily retrofitted.
TLZ (dip-coating centrifuge)
The TLZ was developed for rack goods, as circulation is not necessary or possible for certain parts. The TLZ (dip-coating centrifuge). Parts with a length of up to 750 mm can be coated without any problems. We have developed the TLZ300 for laboratory applications or for coating small quantities.
Here, the product can be dipped directly into a hobbock container and spun off. It is suitable for coating parts with water-based and solvent-based paints.

Questions Answers
Which products can be coated in a TULZ ®?
The TULZ ® coating system can be used to coat all types of bulk goods such as screws, clips, nuts, but also rack dip rack goods and thick bolts for wind turbines.
Which parameters can be set on a coating centrifuge?
With a coating centrifuge, parameters such as speeds, spin-off speeds, coating times and immersion and swivel angles can be set.
What is a TULZ ® ?
A TULZ ® is a dip spin coating centrifuge. The TULZ ® is suitable for the dip spin process for applying zinc flake and other coatings. It is one of the 4 modules in WMV Apparatebau’s catalog of modular coating systems.
