Single chamber pretreatment tunnel SPT+

The SPT+ is the premium single chamber pretreatment tunnel within the ESTEE range. In this case, the beam is brought into the tunnel manually and the nozzles make an oscillating movement over the workpiece.

The SPT+ combines multiple (2 to 4) chemical treatments in one tunnel section, using our unique fluid distribution system. Due to this system and the fact that the tunnel and baths are constructed solely of polypropylene, minimal contamination of liquids is obtained.

Due to the insulating properties of polypropylene (in combination with the selective use of rock wool) and the use of a high-efficiency central heating circuit, energy consumption is reduced to a minimum. In addition, special attention has been paid to the operator’s ease of use and the serviceability of the installation.

Due to the insulating properties of polypropylene (in combination with the selective use of rock wool) and the use of a high-efficiency central heating circuit, energy consumption is reduced to a minimum.

✓ Minimal water and chemical consumption

  • The unique fluid distribution system
  • The use of polypropylene for all internal components: the low surface tension of polypropylene ensures that drops remain minimally ‘sticky’
  • High-performance nylon sealing brushes, which minimise vapor transmission

✓ Minimal energy consumption

  • Double insulation of the heated baths: combination of rock wool and polypropylene!
  • The use of high-efficiency plate heat exchangers in combination with a high-efficiency central heating boiler
  • Optimized fan control: heat is only extracted from the tunnel when required

✓ Long service life

  • Vertical centrifugal pumps are extremely reliable and maintenance-free
  • Polypropylene retains its properties even after long-term contact with aggressive chemistry
  • Exclusive use of premium valves

✓ Service convenience

  • Double protective sieves ensure that the pump is protected at all times, even during maintenance of the protective sieves
  • The central fiberglass-reinforced grid in the tunnel, e.g. for inspection of the nozzles
  • Our optional platform ESTEE IoT Connect is the ideal tool to provide preventive maintenance

✓ Maximum operator comfort

  • Advanced touchscreen where spraying times, alarms and trends are easily visualized and adjusted
  • Automated opening and closing of the doors

Polypropylene internal construction

  • Excellent chemical resistance
  • 85 times better insulator than stainless steel:
    • thermal conductivity stainless steel: 17 W/mK
    • heat conductivity polypropylene: 0.2 W/mK
  • Minimum contamination between liquids thanks to low surface tension: droplets remain minimally ‘sticky’
  • Piping made of polypropylene does not become brittle after a few years, unlike PVC
  • Easy to clean: retains ‘look & feel’ even after years of intensive production
Minimal contamination between liquids thanks to low surface tension: droplets remain minimally ‘sticky’
Tunnel parts & bath from Inox

→ Charges, more difficult to clean and less insulating

All in double-wall polypropylene

→ Maximum chemical resistance and ease of cleaning, excellent thermal insulator, low surface tension → minimal water and chemical consumption
