Integrated system

The WSP-H torch is a complete spray system designed for heavy-duty industrial spraying.
It comes fully equipped with all necessary components including:
  • DC power supply.
  • Water system with process feedback control.
  • Water coolers.
  • Modern software tailored for day-to-day easy use.
  • Spraying parameter library and remote online helpdesk.
  • Automated powder injector positioning system supporting up to 3 feed lines (optional).
  • Set of consumables.
  • Any standard powder feeder(s) capable of delivering requested feed rates can be integrated. Combination of several standard feeders is often used for extreme throughputs.

Dedicated feeder for spraying liquid NEW

WSP-H system may be now equipped with dedicated 2nd generation liquid feeder, which was designed to inject suspensions and solutions with high feed rates (up to 300 ml/min).

Selected features:

  • On-line flow rate control (Coriolis flow meter).
  • Pneumatic operation (pressure up to 8 bars).
  • 3 x 5 liters containers for continuous deposition or spraying composite materials.
  • Stirrer and peristaltic recirculation preventing suspension sedimentation and clogging.
  • Remote touchscreen control from your mobile or PC.
  • Suspensions with up to 75 wt.% solid load were successfully sprayed.
  • Setup is customizable upon customers request.
  • May be combined with powder spraying - "hybrid concept".
  • Compact design.
  • Can be sold separately to support your current torch.
