Coater for small batches

Even though specifically designed for small batches, the R 60 coater offers all the functional features of its larger siblings. With the new Rotamat R 60 Walther Trowal is rounding off its equipment range for coating mass produced bulk parts down to very small batches. For the very first time it is now possible to effectively coat small part volumes of up to 15 liters (4 gallons).

With a drum diameter of only 600 mm (24”) this coater is ideally suited for processing small part batches like, for example, in the aerospace industry, where batch sizes rarely exceed 50 l (13 gallons). This also includes metallic work pieces with high bulk weights, which might get damaged in larger drums through the intensive part-on-part contact. These include spikes for snow tires, bullets and balancing weights.

Frank Siegel, the sales manager for “coating technologies” at Walther Trowal can now offer the right machine for practically any coating application: “We have many customers who must coat small part batches but do not want to give up the high quality standard we achieve with our Rotamat models R 80 and R 90. With the new R 60 coater you can now effectively process small part batches without having to invest in a larger machine”.

Features include:

Precise control of the inlet air temperature

The measuring point for the inlet air temperature is immediately at the drum entry. Compared to measuring the temperature with a sensor behind the air heating unit the measurement is now much more direct allowing extremely precise temperature readings. 

Eco-friendly operation

For typical applications – today 90% of all customers are using water-based paint – Walther Trowal supplies a specially adapted filtering system. For coating tasks with solvent-based paints the new R 60 – like with the bigger Rotamat units – can be equipped with a four stage exhaust air filtering system with a Papp filter, a filter mat and two pocket filters.

Low energy requirements

The capacity of the heating unit was adapted to the smaller drum diameter, resulting in considerably lower overall energy requirements. Depending on the technical characteristics of the work pieces and/or paint Walther Trowal can equip the machine with PID or pulse control for the heating unit. The result: Customers can also use paint types that do not allow going over or below certain operating temperatures.
