Concept Stream

Concept Stream, Robatech's tankless melter for hot melt adhesives with Melt-on-Demand technology assures a fast heat-up time and an efficient and safe production with maximum uptime.

The tankless hot melt system is designed for melting and pumping of thermoplastic hot melt in granular form. It gently melts on demand and therefore is applicable for both high and low glue consumption applications. Thanks to the fast heat-up time of 16 minutes to 160°C the Concept Stream is quickly operational. In addition, the adhesive system achieves a high melting rate performance of 9 kg/h or 15 kg/h with minimum space. Click here for more information.

Innovative melting technology

• 100% increased melting rate - a small tank for high performance (8 kg/h) with minimum space
• MOD (Melt-on-Demand) technology only melts the quantity of adhesive you need, when you need it
• The gentle melting and conveying reduces the risk of charring and nozzle blockage to a minimum and increases the adhesive filters life span
• Even for applications with low glue consumption
