RobaPUR 2 MOD

The RobaPUR 2 MOD adhesive melter is designed for processing different hot melt adhesives in block, granular, and cushion form. Particularly developed for demand-depending melting (Melt-on-Demand), it is suitable for processing almost all commercially available PUR adhesives as well as for PSA, EVA, and APAO hot melt adhesives.

The overall design of the RobaPUR 2 MOD is tailored to flexible production with short retrofit times. Switching between reactive and thermoplastic adhesives as well as color changes are quick and easy – without major cleaning effort. The innovative magazine and melting concept enables a significant increase in the melting rate to up to 10 kg/h. Depending on the pump selection, the adhesive melter can achieve delivery capacities of 9 – 12 kg/h. In highly dynamic processes (SpineCoat applications, adhesive binding in perfect binder soft covers 200 – 2000 T/h), up to 50 kg/h are possible.

Melt-on-Demand (MOD) technology ensures comprehensive protection of the adhesive characteristics of the melted material.
Processing of most commercially available PUR hot melt adhesives without additional inert gas flushing and active cooling.
Adhesive viscosities (depending on variant and pump type): 500 - 120,000 mPas
Adhesives with and without inliner
Self-calibrating level sensor for precise filling level monitoring
Consistent thermal separation between heating zones and magazine for high operating safety
Non-stuck coating for reduced and quick adhesive changes with different color (PUR applications in the woodworking industry)
TRM standard graphic panel for language-independent operation
Integrated AS IK 40 or AS IK 10 application control

The RobaPUR 2 MOD is available in three variants with different pump configurations. With that, the adhesive melter can be tailored optimally to customer- and process-specific requirements.

1-block magazine

The 1-block magazine is suitable for simple applications with low adhesive flow.

Magazine for 2...2.5 kg block.
Basin filling: Gerotor pump GPR 12, max. 9 kg/h, viscosities from 2,500 to 120,000 mPas
Nozzle application: Gear pump ZPR 12, max. 12 kg/h, viscosities from 500 to 120,000 mPas
For adhesives without inliner

2-block magazine

The 2-block magazine is recommended for applications with high adhesive flow. Compared to the 1-block magazine, significantly less refilling intervals are required and the process performance is improved with increased production due to higher magazine filling.

1-block magazine with press

The 1-block magazine with press is available for highly dynamic processes. It was specially developed for the use in clocked PUR applications of the bookbinding industry.

Magazine for 2...2.5 kg block.
Basin filling: Gerotor pump GPR 12, max. 9 kg/h, viscosities from 2,500 to 120,000 mPas
PUR spine nozzle application: Gear pump ZP3 S, max. 50 kg/h, viscosities from 500 to 10,000 mPas
For PUR hot melt adhesives with inliner

Thanks to the high melting rate and different configurations, the RobaPUR 2 MOD can be used in different applications and processes:

Packaging industry ISC 200
Graphical industry ISC 300
Textile industry ISC 590
Wood industry ISC 690
Construction supply industry ISC 790
Automotive industry ISC 820

Typical areas of application of the RobaPUR 2 MOD are basin filling, manual application using a hand applicator, as well as bead and surface application with nozzle systems.
