SMART-4: Spiroflow Material Automatic Refilling Technology

System OVerview

Introducing the new Spiroflow Melter Automatic Refilling Technology from Spiroflow Systems, developed to convey small format hot-melt adhesives to hot melt tanks. The portable SMART-4  and SMART-Bulk systems automatically deliver materials on demand to multiple locations.

The SMART-4 utilizes a portable to hopper and vacuum lances to refill tanks up to 20m (60′) away.

Looking to supply more than four locations? The SMART-Bulk system is capable of feeding materials to more than eight locations at distances of over 60m (200 ft), from a single bulk bag discharger.


  1. A level probe continually senses the material level in each receiver vessel
  2. The control system receives a low-level signal from each vessel when it requires more material
  3. A predetermined amount of material is quickly conveyed via venturi transfer lines to maintain optimal levels and temperatures of material in each location
  4. An audible and visible alarm quickly alerts the operator of low material level in the SMART-4.
