Ecological gluing: with GREENLINE on the “green line”
Tuesday 04. May 2010 - Robatech's market appearance has been characterized by a green logo for more than 30 years, and the Concept hotmelters of the latest GREENLINE generation are also "green" because their working mode is particularly energy saving. Up to 17) percent energy can be saved in combination with a heated hose NW 6 mm and the fully insulated SX Diamond applicator heads which Robatech originally presented as a world's first at the Interpack 2008 exhibition.
This energy saving is the result of an exact analysis which Robatech carried out in-house for each component: We determined where the overall system emits the most heat, and then insulated these areas specifically. “From the applicator head over the hose right to the hotmelter we carefully investigated all appliance components for their energy consumption and heat losses. In this way we found out where to attack in order to achieve perceivable energy savings. The first step was to design our fully-insulated applicator head SX Diamond which consumes up to 60% less energy than the preceding models. Within the framework of our GREENLINE concept we also exchanged the hoses: Energy can also be saved by using a hose of diameter 6 mm instead of the previous 8 mm. The latest measures we implemented with a view to “greener” and more ecological Robatech adhesive applicator systems are the special insulation with which we provide the melting tank of our well-proven Concept hotmelters and the cover over the adhesive distributor. All these optimizations enable us to save 17) percent energy compared with the hotmelt applicator systems offered so far. This puts us in the lead also when it comes to ecologically working hotmelt applicator systems. A further plus of the insulation of the applicator head and the insulated cover over the adhesive distributor is the improved protection of the operating personnel: The danger of personal injury (burns) during operation of the appliances is reduced to the minimum”, explains Hanspeter Huber, Product Manager Packaging Industry at Robatech.
Robatech sets a clear example with its GREENLINE concept: Optimizations as well as new and further developments in the sense of more ecology, environment friendliness and sustainability are initiated and realized step by step.
Since December 2009 the Concept hotmelt series with tank volumes of 5 and 8 litres (the best-selling models of Robatech’s Concept range) come exclusively in the GREENLINE execution with special insulation – and this at the same price as the preceding models. At a later point in time the Concept hotmelters with bigger tank volumes will also become available with the special GREENLINE insulation, at no extra charge. Moreover, Robatech has further “green projects” in the pipeline.
1) The following two hotmelt systems were measured and compared:
a) Concept B 5/2, one heated hose NW 8 mm / 1.8 m, one jetting head AX100
b) Concept B 5/2 “GREENLINE”, one heated hose NW 6 mm / 1.8 m, one jetting head SX Diamond.
