Water Heater Blast

Pangborn Europe Water Heater Blast Machine technology is second to none for surface preparation prior to enamelling of water heater internal surfaces and it has been the preferred choice of the major manufacturers world-wide over the last decades.

In a key phase of the water heater manufacturing, shot blasting is more and more replacing the pickling process due to low environmental impact (no pickling acids and sludges) and consequent indirect dramatic cost savings.

The Water Heater Blast Machines are modern, automatic and fully programmable. Pangborn Europe’s technique of rotating blasting lances with air compressed nozzles avoids the need to install special rotating hooks on the overhead conveyor, an evident limitation of other existing blasting systems. This results in a more reliable blasting performance and is an unquestioned cost reduction for the overhead conveyor purchase and maintenance, considering that the overhead conveyor is usually common to the complete coating line including enamelling and furnace equipments.

Designed to perform the internal blasting for water heaters/boilers with a max 600 mm diameter and up to 2000 mm height (standard version), the water heater blast machine consists of blasting stations (up to 10) equipped with different nozzle types according to the area to be treated and independent centering systems, for a production rate of 170 pcs/h (standard version). Special solutions are also available depending on specific needs.

  • Power & Free conveyor
  • Automatic pieces identifier for PLC programs
  • Two or three steps cycle
  • Specific nozzles set for bottomless heaters
  • Independent centering systems
  • Abrasive removal in blow-off and shaking stations
