Premelters

Melting machines for hotmelts and reactive PUR adhesives

 

The motto for using our premelters is: no half-measures!

Our standard premelters for adhesive application and coating systems can melt up to 240 kg of adhesives per hour. Optionally, we can also implement higher melting capacities for specific customers.


Our Melters automatically supply the machine with hot, liquid adhesive – but only ever as much as is needed at the specific point in time.


We manufacture premelters for:

  • Granulated hotmelts
  • Reactive adhesives (PUR, polyurethane-based) in a closed-loop system

Control is carried out by means of capacitive level control in the melting tank of the respective application machine or using a timer.


Thanks to their individual and needs-based control, our premelting systems are extremely energy-saving and economical. Our premelting systems can be expanded even further with a wide range of accessories such as a vacuum conveyor with a granulate reservoir, for instance.


Efficient premelters from H&H Klebetechnologie: development, production, installation, service – all from a single source.

Advantages of premelters by H&H Klebetechnologie

Optimal and economical material processing – thanks to premelters

Thanks to their extremely short heating time and needs-based control, our premelting systems are highly energy-saving and very economical.

Gentle handling of hotmelts and reactive adhesives (PUR)


Thermal stress for the hotmelts is minimized thanks to needs-based melting.

Increased production efficiency

Thanks to fully-automatic control by means of capacitive level control or the alternative use of a timer, significantly more attention can be paid to the actual production process.

The alternative to costly material extruders

Due to their compact dimensions and comparatively low price, our premelting systems are a clever alternative to material extruders. High and extremely high throughput volumes can also be optionally implemented.

Overview of PUR melting units

PUR premelter - PUVS 130-B
Vorschmelzer PUVS 130 B | H&H Klebetechnologie
Description

The reactive adhesive (e.g. PUR adhesive) is stored in the premelter's melting pipe. The pneumatically actuated cylinder presses the adhesive through the electrically heated melting plate as required.

Melting quantity control is carried out by means of capacitive level control in the application machine's melting tank. Needs-based melting leads to only low thermal stress for the PUR adhesives.
The PUR series premelters are equipped with an airtight melting tank and a connection for nitrogen, dry air or inert gas.
All components that come into contact with reactive adhesive are coated with Teflon.

Technical data
  • For reactive adhesives without outer packaging or bags with diameters of 130 and 150 mm
  • No over-boiling, no overloading
  • Low risk of adhesive decomposition
  • Almost no adhesive wastage and no adhesive residues
  • Closed-loop system
  • Weight approx. 140 kg
  • For mounting on the machine
  • Control system can be networked with the application machine or system

PUR premelter - PUVS 280-P
Vorschmelzer PUVS 280 P Galgen
Description

The reactive adhesive (e.g. PUR adhesive) is stored in the premelter's melting pipe. The pneumatically actuated cylinder presses the adhesive through the electrically heated melting plate and the blocking facility into the heated hose(s) as required. These end at an adhesive filling valve on the adhesive melting tank and ensure a continuous quantity of hotmelt. Several machines can be supplied simultaneously with processed adhesive using up to four heated hoses.

Melting quantity control is carried out by means of capacitive level control in the application machine's melting tank. Needs-based melting leads to only low thermal stress for the PUR adhesives.
The PUR series premelters are equipped with an airtight melting tank and a connection for nitrogen, dry air or inert gas.
All components that come into contact with reactive adhesive are coated with Teflon.



Technical data
